Chiropractic Cost-Effectiveness
Health Insights Today ~ FULL TEXT

In the current economic and political climate, one of the most important arguments to be made for any health care method is that it is cost-effective. As a result, researchers are redoubling their efforts to identify cost-effective approaches. This includes a growing number of studies addressing the cost-effectiveness of chiropractic services. Chiropractors and chiropractic students need to understand this information and to share it with others.

The following is a collection of studies relating to the cost effectiveness and efficacy associated with chiropractic care and the procedures that doctors of chiropractic provide. The American Chiropractic Association, The International Chiropractic Association, The Congress of State Associations, and the Association of Chiropractic Colleges appreciate the opportunity to provide these materials for your review. This presentation is divided into several parts:

  • Background studies, detailing that LBP is much more complex than the literature leads us to believe;
  • Cost-Effectiveness Studies;
  • Worker's Compensation Studies (National studies) and
  • Worker's Compensation Studies (State specific studies)
  • Additional Research Studies

The Cost-Effectiveness of Chiropractic ~ 2015
Chapter 2 from:   Practice Analysis of Chiropractic 2015

Provided by the National Board of Chiropractic Examiners (NBCE)

From Page 23:   A recent study of 12,036 records in the Medical Expenditure Panel Survey (MEPS) investigated the costs of treating patients with low back and neck pain (Martin et al., 2012). The study estimated the expenditures for care among complementary and alternative medicine (chiropractic, homeopathy, herbalism, acupuncture, and massage) users relative to non-users. This study included a chiropractic-specific analysis of expenditures for chiropractic users versus non-users, as approximately 75% of all complementary and alternative medicine services were rendered by doctors of chiropractic. Survey data were analyzed for the years 2002-2008. The analysis demonstrated that seeing a CAM/chiropractic provider did not add to overall medical spending. In fact, adjusted annual healthcare costs among chiropractic users were $424 lower for spine-related costs when compared to non-CAM users. Additionally, those who used complementary and alternative providers, including doctors of chiropractic, had significantly lower hospitalization expenditures.

Cost Comparison of Two Approaches to Chiropractic Care for Patients with Acute
and Sub-acute Low Back Pain Care Episodes: A Cohort Study

Chiropractic & Manual Therapies 2020 (Dec 14);   28 (1):   68~ FULL TEXT

Low back pain (LBP) imposes a costly burden upon patients, healthcare insurers, and society overall. Spinal manipulation as practiced by chiropractors has been found be cost-effective for treatment of LBP, but there is wide variation among chiropractors in their approach to clinical care, and the most cost-effective approach to chiropractic care is uncertain. To date, little has been published regarding the cost effectiveness of different approaches to chiropractic care. Thus, the current study presents a cost comparison between chiropractic approaches for patients with acute or subacute care episodes for low back pain.

Treatment of Patients with Low Back Pain:
A Comparison of Physical Therapy and Chiropractic Manipulation

Healthcare (Basel). 2020 (Feb 24);   8 (1):   pii: E44 ~ FULL TEXT

This study analyzed these two strategies and showed that in the short term, chiropractic care is a more cost-effective alternative compared to PT for the treatment of acute low back pain. Chiropractic resulted in a lower cost ($48.56) and higher DALY (0.0043) than the PT over a one-month treatment period and five months follow-up. However, the marginal cost-effectiveness of chiropractic over PT suggests that both treatments were quite similar. Such findings are in line with the earlier studies, which found that the effectiveness and total costs of chiropractic and PT as primary treatments were similar to each other right after treatment and after 6 months follow-up. [3, 22, 32]

Cost-Efficiency and Effectiveness of Including Doctors of Chiropractic to Offer
Treatment Under Medicaid: A Critical Appraisal of Missouri Inclusion of
Chiropractic Under Missouri Medicaid

Journal of Chiropractic Humanities 2019 (Dec 10);   26:   31-52 ~ FULL TEXT

Using a dynamic scoring model to incorporate savings from 3 primary sources, we found that (1) chiropractic care provides better outcomes at lower cost, (2) chiropractic treatment and care leads to a reduction in costs of spinal surgery, and (3) chiropractic care leads to cost savings from reduced use and abuse of opioid prescription drugs.

Conservative Spine Care Pathway Implementation Is Associated with Reduced
Health Care Expenditures in a Controlled, Before-After Observational Study

Journal of General Internal Medicine 2019 (Aug);   34 (8):   1381-1382 ~ FULL TEXT

In this retrospective, controlled, before-after study, we found that implementation of a conservative spine pain treatment pathway was associated with significant reductions in per-member-per-month (PMPM) healthcare expenditures for spine pain care; most cost savings were attributable to reduction in spine surgery costs. Our Poisson model found relatively reduced opioid utilization and relatively increased manual care costs, both anticipated by-products of guideline implementation. [4] While our findings are preliminary, in an era of increasing healthcare costs and use of complex and expensive spine surgery techniques they show promise for meaningful care cost reduction and value enhancement when providers conservatively manage spine pain. Importantly, our analysis underscores the value of using control groups, formal analytics, and academic partnerships to understand the impact of quality improvement and clinical effectiveness projects, measures that have been recommended to improve the robustness of quality improvement efforts. [5]

Chiropractic Integration Within a Community Health Centre: A Cost Description and
Partial Analysis of Cost-utility from the Perspective of the Institution

J Can Chiropr Assoc. 2019 (Aug);   63 (2):   64-79 ~ FULL TEXT

This study evaluated the cost-utility of chiropractic integration for low back pain services within a primary care CHC setting from the perspective of the healthcare institution. Among the subjects followed in this study, the addition of chiropractic care to usual medical care was associated with improved outcomes at a reasonable cost. These outcomes, along with the potential cost savings of such integration, may have important implications for healthcare institutions and their patients, as well as for policy decision-makers and other health stakeholders. Future comparative cost and effectiveness studies with control of confounding are nevertheless needed to evaluate the impact of chiropractic care with or without usual medical care in these settings.

Access to Chiropractic Care and the Cost of Spine Conditions Among Older Adults
American Journal of Managed Care 2019 (Aug);   25 (8):   e230-e236 ~ FULL TEXT

This study is among the first to examine whether access to chiropractic care, a health service that provides a significant amount of the nation’s conservative management of nonspecific back pain, has any effect on Medicare spending. We found some evidence of a relationship between lower accessibility of chiropractic care and higher spending on diagnostic imaging and testing. Future work is required to determine if indeed access to chiropractic care for Medicare beneficiaries in any way breaks the pathway to care that is discordant with practice guidelines

The Use of Complementary and Integrative Health Approaches for Chronic
Musculoskeletal Pain in Younger US Veterans: An Economic Evaluation

PLoS One. 2019 (Jun 5);   14 (6):   e0217831 ~ FULL TEXT

According to our propensity score-weighted HLM analysis, in a cohort of younger Veterans with chronic MSD pain during 2010 through 2013, any use of complementary and integrative health (CIH) was not only cost-effective, it was cost saving. Any use of CIH was associated with an average reduction in healthcare costs of $637, a 0.34-point reduction in pain intensity on a 0-10 pain scale, and a less than one percentage point increase in opioid use during the year after CIH start. Given the VA's growing interest in the use of CIH, further, more detailed analyses of its impacts are warranted.

Cost-effectiveness of Spinal Manipulation, Exercise, and Self-management for
Spinal Pain Using an Individual Participant Data Meta-analysis Approach:
A Study Protocol

Chiropractic & Manual Therapies 2018 (Nov 13);   26:   46 ~ FULL TEXT

This project capitalizes on a unique opportunity to combine clinical and economic data collected in a several clinical trials that used similar methods. The findings will provide important information on the value of spinal manipulation, exercise therapy, and self-management for spinal pain management in the U.S.

Comparative Effectiveness of Usual Care With or Without Chiropractic Care
in Patients with Recurrent Musculoskeletal Back and Neck Pain

J Gen Intern Med. 2018 (Sep);   33 (9):   1469-1477

We found that referred and non-referred participants had comparable clinical outcomes and that chiropractic referral neither added to health care costs nor introduced significant safety concerns. Data suggest that although two thirds of primary care physicians have recommended chiropractic care to their patients, [36] lack of communication remains a major barrier to care coordination. [37, 38] Better integration of chiropractors into conventional care spine management algorithms could represent a sensible approach to enhancing patient-centered care for patients with chronic musculoskeletal pain.

Association Between the Type of First Healthcare Provider and the Duration
of Financial Compensation for Occupational Back Pain

Journal of Occupational Rehabilitation 2017 (Sep);   27 (3):   382-392 ~ FULL TEXT

The type of healthcare provider first visited for back pain is a determinant of the duration of financial compensation during the first 5 months. Chiropractic patients experience the shortest duration of compensation, and physiotherapy patients experience the longest. These differences raise concerns regarding the use of physiotherapists as gatekeepers for the worker's compensation system. Further investigation is required to understand the between-provider differences.

This On-site Chiropractic Clinic Is Saving a Minnesota Manufacturer Big Money
The Star Tribune ~ Jan 1, 2017 ~ FULL TEXT

A year into the project, workers report that they are feeling better and like having health care services at their job. Statistics show that they are incurring injuries at much lower rates. They are also recovering quicker when they do get hurt.   And when it comes to the bottom line, the results have been better than Friendship Homes and Northwestern expected.   For every $1 that the company has invested in the program, it is saving $8 by avoiding more-costly and less-effective treatments, spending less on insurance payments and keeping more workers on the job in the first place, which generates savings through less lost tine for workers and less overtime to compensate for absences.

Cost-effectiveness of Spinal Manipulative Therapy, Supervised Exercise,
and Home Exercise for Older Adults with Chronic Neck Pain

Spine J. 2016 (Nov);   16 (11):   1292-1304

Total costs for spinal manipulative therapy (SMT) + home exercise and advice (HEA) were 5% lower than HEA (mean difference: -$111; 95% confidence interval [CI] -$1,354 to $899) and 47% lower than supervised rehabilitative exercise (SRE) + HEA (mean difference: -$1,932; 95% CI -$2,796 to -$1,097).   SMT+HEA also resulted in a greater reduction of neck pain over the year relative to HEA (0.57; 95% CI 0.23 to 0.92) and SRE+HEA (0.41; 95% CI 0.05 to 0.76). Differences in disability and quality-adjusted life years (QALYs) favored SMT+HEA.

Cost-Effectiveness of Non-Invasive and Non-Pharmacological Interventions for
Low Back Pain: a Systematic Literature Review

Applied Health Econ and Health Policy 2017 (Apr);   15 (2):  173-201 ~ FULL TEXT

Thirty-three studies were identified. Study interventions were categorised as: (1) combined physical exercise and psychological therapy, (2) physical exercise therapy only, (3) information and education, and (4) manual therapy. Interventions assessed within each category varied in terms of their components and delivery. In general, combined physical and psychological treatments, information and education interventions, and manual therapies appeared to be cost effective when compared with the study-specific comparators. There is inconsistent evidence around the cost effectiveness of physical exercise programmes as a whole, with yoga, but not group exercise, being cost effective.

Effectiveness and Economic Evaluation of Chiropractic Care for the Treatment of
Low Back Pain: A Systematic Review of Pragmatic Studies

PLoS One. 2016 (Aug 3);   11 (8):   e0160037 ~ FULL TEXT

Six RCTs and three full economic evaluations were scientifically admissible. Five RCTs with low risk of bias compared chiropractic care to exercise therapy (n = 1), physical therapy (n = 3) and medical care (n = 1). Overall, we found similar effects for chiropractic care and the other types of care and no reports of serious adverse events. Three low to high quality full economic evaluations studies (one cost-effectiveness, one cost-minimization and one cost-benefit) compared chiropractic to medical care. Given the divergent conclusions (favours chiropractic, favours medical care, equivalent options), mixed-evidence was found for economic evaluations of chiropractic care compared to medical care.

The Cost-Effectiveness Triumvirate

Variations in Patterns of Utilization and Charges for the Care of Headache
in North Carolina, 2000-2009: A Statewide Claims' Data Analysis

J Manipulative Physiol Ther. 2016 (May);   39 (4):   229-239 ~ FULL TEXT

Overall utilization and average charges for the treatment of headache increased considerably from 2000 to 2005 and then decreased in each subsequent year. Policy changes that took place between 2005 and 2007 may have affected utilization rates of certain providers and their associated charges. MD care accounted for the majority of total allowed charges throughout the decade. In general, patterns of care involving multiple providers and referral care incurred the largest charges, whereas patterns of care involving single or nonreferral providers incurred the least charges. MD-only, DC-only, and MD-DC care were the least expensive patterns of headache care; however, risk-adjusted charges (available 2006-2009) were significantly lower for DC-only care compared with MD-only care.

Variations in Patterns of Utilization and Charges for the Care of Neck Pain
in North Carolina, 2000 to 2009: A Statewide Claims' Data Analysis

J Manipulative Physiol Ther. 2016 (May);   39 (4):   240-251 ~ FULL TEXT

Increases in utilization and charges were the highest among patterns involving MDs, PTs and referral providers.   These findings are consistent with previous studies showing that medical specialty, diagnostic imaging, and invasive procedures (eg, spine injections, surgery) [17, 19, 20, 21] are significant drivers of increasing spine care costs.   When costs are viewed vertically as if in “silos” (eg, DC-only costs, MD-only costs), increasing utilization of one particular provider is seen as a net cost increase. However, when costs are viewed across the silos, as this study has done, an increase in utilization of one provider group can result in a net cost decrease given its effect on the patient population.   This is an opportunity to view costs laterally versus a confined, vertical analysis.

Variations in Patterns of Utilization and Charges for the Care of Low Back Pain
in North Carolina, 2000 to 2009: A Statewide Claims' Data Analysis

J Manipulative Physiol Ther. 2016 (May);   39 (4):   252-262 ~ FULL TEXT

A major strength of the study was the large amount of low back pain claims made available to us for analysis. The data were from 3,159,362 claims generated by approximately 66,0000 persons over the 2000-2009 decade in North Carolina, in several different pathways of healthcare services. This study and the series of papers it has generated on the treatment of low back pain, neck pain [25] and headache, [26] provides unique economic examination for healthcare policy makers and legislators.   When costs are viewed vertically as if in “silos” (eg, DC-only costs, MD-only costs), increasing utilization of one particular provider is seen as a net cost increase. However, when costs are viewed across the silos, as this study has done, an increase in utilization of one provider group can result in a net cost decrease given its effect on the patient population.   This is an opportunity to view costs laterally versus a confined, vertical analysis.

The Association Between Use of Chiropractic Care and Costs of Care
Among Older Medicare Patients With Chronic Low Back Pain
and Multiple Comorbidities

J Manipulative Physiol Ther. 2016 (Feb);   39 (2):   63-75 ~ FULL TEXT

After propensity score weighting, total and per-episode day Part A, Part B, and Part D Medicare reimbursements during the chronic low back pain (cLBP) treatment episode were lowest for patients who used CMT alone; these patients had higher rates of healthcare use for low back pain but lower rates of back surgery in the year following the treatment episode. Expenditures were greatest for patients receiving medical care alone; order was irrelevant when both CMT and medical treatment were provided.

A Systematic Review Comparing the Costs of Chiropractic Care
to other Interventions for Spine Pain in the United States

BMC Health Serv Res. 2015 (Oct 19);   15:   474 ~ FULL TEXT

The search uncovered 1,276 citations and 25 eligible studies, including 12 from private health plans, 6 from WC plans, and 7 that examined clinical outcomes. Chiropractic care was most commonly compared to care from a medical physician, with few details about the care received. Heterogeneity was noted among studies in patient selection, definition of spine pain, scope of costs compared, study duration, and methods to estimate costs. Overall, cost comparison studies from private health plans and WC plans reported that health care costs were lower with chiropractic care. In studies that also examined clinical outcomes, there were few differences in efficacy between groups, and health care costs were higher for those receiving chiropractic care. The effects of adjusting for differences in sociodemographic, clinical, or other factors between study groups were unclear.

Regional Supply of Chiropractic Care and Visits to Primary Care Physicians
for Back and Neck Pain

J Am Board Fam Med. 2015 (Jul);   28 (4):   481–490 ~ FULL TEXT

Despite the inherent limitations of our study, our findings offer important insights into the indirect effects of Medicare’s chiropractic care benefit on PCP services. Our finding that chiropractic care is associated with fewer visits to PCPs for back and/or neck pain is important for health policymakers to consider. Driven by both increased spending [11, 12] and a series of reports by the Office of the Inspector General, [11–14] Medicare’s chiropractic care benefit is currently being examined. In addition to providing important information regarding the impact of coverage of chiropractic care, our study also underscores the importance of evaluating the indirect effects of ambulatory health services. When extrapolated to the nation (based on our predictions from our adjusted model), we estimate that chiropractic care is associated with a reduction of 0.37 million visits to PCPs for back and/or neck pain at a total cost of $83.5 million (Table 3).

Tracking Low Back Problems in a Major Self-Insured Workforce:
Toward Improvement in the Patient's Journey

J Occup Environ Med. 2014 (Jun);   56 (6):   604-620 ~ FULL TEXT

This comprehensive new study from the Journal of Occupational and Environmental Medicine reveals that chiropractic care costs significantly less than other forms of low back care, and appears to comply with guideline recommendations more closely than than any of the other 4 comparison groups.

Cost-Effectiveness of Manual Therapy for the Management of Musculoskeletal Conditions:
A Systematic Review and Narrative Synthesis of Evidence From
Randomized Controlled Trials

J Manipulative Physiol Ther. 2014 (Jul);   37 (6):   343-362 ~ FULL TEXT

This review identified limited evidence indicating that manual therapy techniques (eg, osteopathic spinal manipulation, physiotherapy consisting of manipulation and mobilization techniques, and chiropractic manipulation), in addition to other treatments or alone, are more cost-effective than usual GP care (alone or with exercise), spinal stabilization, GP advice, advice to remain active, or brief pain management for improving low back pain and/or disability. Similarly, one study [57] demonstrated that spinal manipulation in addition to GP care was more cost-effective than GP care alone in reducing shoulder pain and related disability. The extra costs needed for 1-unit improvement in low back or shoulder pain/disability score or 1 QALY gained were lower than the WTP thresholds reported across the studies.

Cost Analysis Related to Dose-response of Spinal Manipulative Therapy for
Chronic Low Back Pain: Outcomes from a Randomized Controlled Trial

J Manipulative Physiol Ther. 2014 (Jun);   37 (5):   300–311 ~ FULL TEXT

Lost productivity accounts for most societal costs of chronic LBP. Cost of treatment and lost productivity ranged from $3398 for 12 SMT sessions to $3815 for 0 SMT sessions with no statistically significant differences between groups. Baseline patient characteristics related to increase in costs were greater age (P = .03), greater disability (P = .01), lower quality-adjusted life year scores (P = .01), and higher costs in the period preceding enrollment (P < .01). Pain-free and disability-free days were greater for all SMT doses compared with control, but only SMT 12 yielded a statistically significant benefit of 22.9 pain-free days (P = .03) and 19.8 disability-free days (P = .04). No statistically significant group differences in quality-adjusted life years were noted.

CONCLUSIONS:   A dose of 12 SMT sessions yielded a modest benefit in pain-free and disability-free days. Care of chronic LBP with SMT did not increase the costs of treatment plus lost productivity.

Prevention of Low Back Pain: Effect, Cost-effectiveness, and Cost-utility
of Maintenance Care - Study Protocol for a Randomized Clinical Trial
Trials. 2014 (Apr 2);   15:   102 ~ FULL TEXT

This study protocol describes a randomized controlled clinical trial in a multicenter setting investigating the effect and cost-effectiveness of preventive manual care (chiropractic maintenance care) in a population of patients with recurrent or persistent LBP.Four hundred consecutive study subjects with recurrent or persistent LBP will be recruited from chiropractic clinics in Sweden.

Health Care Utilization and Costs Associated with Adherence to Clinical Practice Guidelines for
Early Magnetic Resonance Imaging Among Workers with Acute Occupational Low Back Pain

Health Serv Res. 2014 (Apr);   49 (2):   645-665 ~ FULL TEXT

Nonadherence to guidelines for early MRI was associated with increased likelihood of lumbosacral injections or surgery and higher costs for out-patient, inpatient, and nonmedical services, and disability compensation.

Conservative Spine Care: Opportunities to Improve the Quality and Value of Care
Popul Health Manag. 2013 (Dec);   16 (6):   390-396 ~ FULL TEXT

A previous article analyzed current practices regarding the use of coronary stents in the chronic stable angina patient. [4] Musculoskeletal disorders represent another diagnostic class that, while usually not life threatening, results in a high prevalence of morbidity and significant societal burden. [5] Low back pain (LBP) management in particular has been linked to inefficiency and waste. [6] This is likely related, in part, to the growing list of treatment approaches recommended for conservative care (pharmacologic and non-pharmaceutical options) and the difficulty in determining the best option for each patient. [7]

Trends in the Use and Cost of Chiropractic Spinal Manipulation Under Medicare Part B
Spine J. 2013 (Nov);   13 (11):   1449–1454 ~ FULL TEXT

The number of Medicare beneficiaries who used chiropractic spinal manipulation grew 13% from 2002 to 2004, remained flat through 2007, and then declined 5% through 2008. An estimated 1.7 million beneficiaries (6.9%) used 18.6 million allowed chiropractic services in 2008. In inflation-adjusted dollars, allowed charges per user increased 4% through 2005 and then declined by 17% through 2008; payments per user increased by 5% from 2002 to 2005 and then declined by 18% through 2008. Expenditures for chiropractic in 2008 totaled an estimated $420 million. Longitudinal trends in allowed claims for spinal manipulation varied by procedure: the relative frequency of treatment of one to two spinal regions declined from 43% to 29% of services, treatment of three to four regions increased from 48% to 62% of services, and treatment of five regions remained flat at 9% of services.

Early Predictors of Lumbar Spine Surgery After Occupational Back Injury:
Results From a Prospective Study of Workers in Washington State

Spine (Phila Pa 1976). 2013 (May 15);   38 (11):   953-964 ~ FULL TEXT

In this sample, 9.2% of workers receiving temporary total disability compensation soon after an occupational back injury went on to have lumbar spine surgery in the next three years. This rate is similar to rates of lumbar spine surgery following occupational back injury reported in other studies (9.8% [17] and 10.8% [27]). Measures in four domains predicted surgery: sociodemographic, pain and function, clinical status, and health care.

The Association of Complementary and Alternative Medicine Use and Health Care
Expenditures for Back and Neck Problems

Medical Care 2012 (Dec);   50 (12):   1029-1036 ~ FULL TEXT

While health care conversations increasingly mention chiropractic care as a viable option for back and neck pain - and research increasingly supports its utility from a clinical standpoint - this nationwide study of complementary and alternative medicine (CAM)-related health care expenditures by 12,000-plus adults (ages 17 and older) with spinal conditions lends support to the suggestion that CAM in general, and chiropractic specifically, is also a cost-effective alternative to traditional medical care.

A Systematic Review and Meta-analysis of Efficacy, Cost-effectiveness, and Safety
of Selected Complementary and Alternative Medicine for Neck and Low-back Pain

Evid Based Complement Alternat Med. 2012 (Nov 24);   2012:   953139 ~ FULL TEXT

Reports of 147 randomized trials and 5 non-randomized studies were included. CAM treatments were more effective in reducing pain and disability compared to no treatment, physical therapy (exercise and/or electrotherapy) or usual care immediately or at short-term follow-up. Trials that applied sham-acupuncture tended towards statistically non-significant results. In several studies, acupuncture caused bleeding on the site of application, and manipulation and massage caused pain episodes of mild and transient nature.

Spinal Manipulation Epidemiology: Systematic Review of Cost Effectiveness Studies
J Electromyogr Kinesiol. 2012 (Oct);   22 (5):   655-662 ~ FULL TEXT

Six cost-effectiveness and cost-utility analysis were included. All included studies had a low risk of bias scoring =16/19 on the CHEC-List. SMT was found to be a cost-effective treatment to manage neck and back pain when used alone or in combination with other techniques compared to GP care, exercise and physiotherapy.

Cost-effectiveness of Conservative Treatments for Neck Pain:
A Systematic Review on Economic Evaluations

European Spine Journal 2012 (Aug);   21 (8):   1441-1450 ~ FULL TEXT

A total of five economic evaluations met the inclusion criteria. All studies were conducted alongside randomised controlled trials and included a cost-utility analysis, and four studies also conducted a cost-effectiveness analysis. Most often, the economic evaluation was conducted from a societal or a health-care perspective. One study found that manual therapy was dominant over physiotherapy and general practitioner care, whilst behavioural graded activity was not cost-effective compared to manual therapy. The combination of advice and exercise with manual therapy was not cost-effective compared to advice and exercise only. One study found that acupuncture was cost-effective compared to a delayed acupuncture intervention, and another study found no differences on cost-effectiveness between a brief physiotherapy intervention compared to usual physiotherapy. Pooling of the data was not possible as heterogeneity existed between the studies on participants, interventions, controls, outcomes, follow-up duration and context related socio-political differences.

Value of Chiropractic Services at an On-site Health Center
J Occupational and Environmental Medicine 2012 (Aug);   54 (8):   917-921 ~ FULL TEXT

Although previous research has demonstrated the benefits of chiropractic care, to the best of our knowledge this study is the first to evaluate its impact when offered at an on-site health center. [6-10, 14-17] Given the convenience and quality of care provided by on-site health centers, it was hypothesized that on-site chiropractic care would be more beneficial than off-site clinic care. Despite some limitations that may have weakened the conclusions, the findings suggest on-site chiropractic services are associated with lower health care utilization of certain services and improved functional status of musculoskeletal conditions.

A Model of Integrative Care for Low-back Pain
J Altern Complement Med. 2012 (Apr);   18 (4):   354-362 ~ FULL TEXT

Historically, federal agencies including the National Institutes of Health, the Agency for Healthcare Research and Quality, Centers for Medicare and Medicaid, the Department of Defense, and the Veterans Administration have not sponsored research aimed at evaluating the cost effectiveness — or lack thereof — of emerging models of multidisciplinary, “integrative care” in the treatment of common medical conditions. This study argues that such comparative effectiveness research in this area is feasible, promising, and warranted, at least with regard to adults with persistent LBP.

Cost-Effectiveness of General Practice Care for Low Back Pain: A Systematic Review
European Spine Journal 2011 (Jul);   20 (7):   1012-1023 ~ FULL TEXT

Eleven studies were included; the majority of which conducted a cost-effectiveness or cost-utility analysis. Most studies investigated the cost-effectiveness of usual general practitioner (GP) care. Adding advice, education and exercise, or exercise and behavioural counselling, to usual GP care was more cost-effective than usual GP care alone. Clinical rehabilitation and/or occupational intervention, and acupuncture were more cost-effective than usual GP care. One study investigated the cost-effectiveness of guideline-based GP care, and found that adding exercise and/or spinal manipulation was more cost-effective than guideline-based GP care alone.

The Trials of Evidence:
Interpreting Research and the Case for Chiropractic

The Chiropractic Report ~ July 2011 ~ FULL TEXT

For the great majority of patients with both acute and chronic low-back pain, namely those without diagnostic red flags, spinal manipulation is recommended by evidence-informed guidelines from many authoritative sources - whether chiropractic (the UK Evidence Report from Bronfort, Haas et al. [1]), medical (the 2007 Joint Clinical Practice Guideline from the American College of Physicians and the American Pain Society [2]) or interdisciplinary (the European Back Pain Guidelines [3]).

Health Maintenance Care in Work-Related Low Back Pain and Its
Association With Disability Recurrence

J Occupational and Environmental Medicine 2011 (Apr);   53 (4):   396-404 ~ FULL TEXT

This study found that you are twice as likely to end up disabled if you get your care from a Physical Therapist, rather than from a DC, and that patients were 60% more likely to be disabled if they choose an MD to manage their care, rather than a DC.

A Hospital-Based Standardized Spine Care Pathway:
Report of a Multidisciplinary, Evidence-Based Process

J Manipulative Physiol Ther 2011 (Feb);   34 (2):   98-106 ~ FULL TEXT

A health care facility (Jordan Hospital) implemented a multidimensional spine care pathway (SCP) using the National Center for Quality Assurance (NCQA) Back Pain Recognition Program (BPRP) as its foundation. The findings for 518 consecutive patients were included. One hundred sixteen patients were seen once and triaged to specialty care; 7% of patients received magnetic resonance imagings. Four hundred thirty-two patients (83%) were classified and treated by doctors of chiropractic and/or physical therapists. Results for the patients treated by doctors of chiropractic were mean of 5.2 visits, mean cost per case of $302, mean intake pain rating score of 6.2 of 10, and mean discharge score of 1.9 of 10; 95% of patients rated their care as "excellent.

Cost-effectiveness of Guideline-endorsed Treatments for Low Back Pain: A Systematic Review
European Spine Journal 2011 (Jul);   20 (7):   1024-1038 ~ FULL TEXT

This systematic review of the cost-effectiveness of treatments endorsed in the APS-ACP guidelines found that spinal manipulation was cost-effective for subacute and chronic low back pain, as were other methods usually within the chiropractor’s scope of practice (interdisciplinary rehabilitation, exercise, and acupuncture). For acute low back pain, this review found insufficient evidence for reaching a conclusion about the cost-effectiveness of spinal manipulation. It also found no evidence at all on the cost-effectiveness of medication for low back pain.

J Manipulative Physiol Ther 2010 (Nov);   33 (9):   640-643 ~ FULL TEXT

Paid costs for episodes of care initiated with a DC were almost 40% less than episodes initiated with an MD. Even after risk adjusting each patient’s costs, we found that episodes of care initiated with a DC were 20% less expensive than episodes initiated with an MD. This clearly demonstrates the savings that are possible when a patient is permitted to choose a chiropractor, rather than an MD for their care.

Cost and Use of Conservative Management of Lumbar Disc Herniation
Before Surgical Discectomy

Spine J. 2010 (Jun);   10 (6):   463–468

Lumbar discectomy is one of the most common spine surgical procedures. The average charge for discectomy procedure was $7,841. Although a large number of patients will ultimately require surgical intervention, given that many patients will improve with nonoperative therapy, a trial of conservative management is appropriate. This study reviewed the costs associated with various conservative measures.

Functional Scores and Subjective Responses of Injured Workers With Back
or Neck Pain Treated With Chiropractic Care in an Integrative
Program: A Retrospective Analysis of 100 Cases

J Manipulative Physiol Ther. 2009 (Nov);   32 (9):   765-771 ~ FULL TEXT

Injured workers with either an acute or subacute injury had significantly lower posttreatment FRI scores compared with individuals with a chronic injury. The FRI change scores were significantly greater in the acute group compared with either the subacute or chronic injured workers. Workers in all categories showed improved posttreatment tolerance for work-related activities and significantly lower posttreatment subjective pain scores.The study identified positive effects of chiropractic management included in integrative care when treating work-related neck or back pain. Improvement in both functional scores and subjective response was noted in all 3 time-based phases of patient status (acute, subacute, and chronic).

Do Chiropractic Physician Services for Treatment of Low-Back and Neck Pain Improve the Value
of Health Benefit Plans? An Evidence-Based Assessment of Incremental Impact
on Population Health and Total Health Care Spending

Mercer Health and Benefits LLC ~ October 12, 2009 ~ FULL TEXT

This report combined a rigorous analysis of direct and indirect costs with equally relevant (though often missing from such analyses) evidence concerning clinical effectiveness. In other words, Choudhry and Milstein started with the assumption that low cost is only a virtue if a product or service effectively delivers what it promises. Including both clinical effectiveness and cost in their analysis, they concluded that chiropractic care was far more valuable than medical treatment for neck and low back pain.

Colorado Workers' Compensation: Medical vs Chiropractic Costs for the Treatment of Lowback Pain
J Manipulative Physiol Ther. 2009 (Feb);   32 (2 Sup):  S108-116 ~ FULL TEXT

This study adds to the understanding of differences associated with costs and services provided by DCs and MDs when treating simple and nonspecific LBP. It does not bring about an understanding of patient satisfaction for each provider or explain all potential benefits that might have been achieved by treatment. Results from our study appear to demonstrate that chiropractic care is more expensive than medical care when treating relatively simple forms of LBP. Because costs can greatly increase because of repeated treatments, the difference in expenses is mainly due to more services and longer treatment periods. Further research is needed to evaluate quality of life and patient satisfaction related to different treatment approaches, as well as follow-up of patient's functional status and stability upon return to work, resumption of activities of daily livings, and impacts of relapses. Future evaluations should also examine effectiveness when treating more complex disorders causing spine and LBP. Cost-effectiveness has become very important when choosing a heath care provider for most third-party payers. However, because patients respond differently to different forms of treatment, it would be in the best interest of both the insurance company and the patient for the patient to be provided preferred treatment options for his/her condition and to take an active role in his/her overall treatment plan.

Clinical Utilization and Cost Outcomes from an Integrative Medicine
Independent Physician Association: An Additional 3-year Update

J Manipulative Physiol Ther 2007 (May);   30 (4):   263-269 ~ FULL TEXT

A new retrospective analysis of 70,274 member-months in a 7-year period within an IPA, comparing medical management to chiropractic management, demonstrated decreases of 60.2% in-hospital admissions, 59.0% hospital days, 62.0% outpatient surgeries and procedures, and 83% pharmaceutical costs when compared with conventional medicine IPA performance. This clearly demonstrates that chiropractic nonsurgical nonpharmaceutical approaches generates reductions in both clinical and cost utilization when compared with PCPs using conventional medicine alone.

Effects of a Managed Chiropractic Benefit on the Use of Specific Diagnostic

J Manipulative Physiol Ther 2005 (Oct);   28 (8):   564-569 ~ FULL TEXT

For the treatment of low back and neck pain, the inclusion of a chiropractic benefit resulted in a reduction in the rates of surgery, advanced imaging, inpatient care, and plain-film radiographs. This effect was greater on a per-episode basis than on a per-patient basis.

Cost-effectiveness of Medical and Chiropractic Care for Acute and Chronic Low Back Pain
J Manipulative Physiol Ther 2005 (Oct);   28 (8):   555-563 ~ FULL TEXT

Acute and chronic chiropractic patients experienced better outcomes in pain, functional disability, and patient satisfaction. Chiropractic care appeared relatively cost-effective for the treatment of chronic LBP. Chiropractic and medical care performed comparably for acute patients. Practice-based clinical outcomes were consistent with systematic reviews of spinal manipulation efficacy: manipulation-based therapy is at least as good as and, in some cases, better than other therapeusis. This evidence can guide physicians, payers, and policy makers in evaluating chiropractic as a treatment option for low back pain.

Cost Effectiveness of Physical Treatments for Back Pain in Primary Care
British Medical Journal 2004 (Dec 11);   329 (7479):   1381 ~ FULL TEXT

We believe that this is the first study of physical therapy for low back pain to show convincingly that both manipulation alone and manipulation followed by exercise provide cost effective additions to care in general practice. Indeed, as we trained practice teams in the best care of back pain, we may have underestimated the benefit of physical therapy (spinal manipulation) when compared with "usual care" in general practice. The detailed clinical outcomes reported in the accompanying paper reinforce these findings by showing that the improvements in health status reported here reflect statistically significant improvements in function, pain, disability, physical and mental aspects of quality of life, and beliefs about back pain.(1)

Comparative Analysis of Individuals With and Without Chiropractic Coverage:
Patient Characteristics, Utilization, and Costs

Archives of Internal Medicine 2004 (Oct 11);   164 (18):   1985-1892 ~ FULL TEXT

A 4-year retrospective claims data analysis comparing more than 700,000 health plan members within a managed care environment found that members had lower annual total health care expenditures, utilized x-rays and MRIs less, had less back surgeries, and for patients with chiropractic coverage, compared with those without coverage, also had lower average back pain episode-related costs ($289 vs $399).
The authors concluded:   "Access to managed chiropractic care may reduce overall health care expenditures through several effects, including (1) positive risk selection; (2) substitution of chiropractic for traditional medical care, particularly for spine conditions; (3) more conservative, less invasive treatment profiles; and (4) lower health service costs associated with managed chiropractic care."

These data, with the acknowledged limitations of an insurance database, indicate lower treatment costs, less workdays lost, lower compensation payments, and lower utilization of ancillary medical services for patients treated by DCs. Despite the lower cost of chiropractic management, the use of chiropractic services in North Carolina appears very low.

Chiropractic Care: Is It Substitution Care or Add-on Care in Corporate Medical Plans?
J Occup Environ Med 2004 (Aug);   46 (8):   847-855

An analysis of claims data from a managed care health plan was performed to evaluate whether patients use chiropractic care as a substitution for medical care or in addition to medical care. For the 4-year study period, there were 3,129,752 insured member years in the groups with chiropractic coverage and 5,197,686 insured member years in the groups without chiropractic coverage.   These results (of this file review) indicate that patients use chiropractic care as a direct substitution for medical care.

Estimates and Patterns of Direct Health Care Expenditures Among Individuals
With Back Pain in the United States

Spine (Phila Pa 1976) 2004 (Jan 1);   29 (1):   79-86 ~ FULL TEXT

In 1998, total health care expenditures incurred by individuals with back pain in the United States reached 90.7 billion dollars and total incremental expenditures attributable to back pain among these persons were approximately 26.3 billion dollars. On average, individuals with back pain incurred health care expenditures about 60% higher than individuals without back pain (3,498 dollars vs. 2,178 dollars). Among back pain individuals, at least 75% of service expenditures were attributed to those with top 25% expenditure, and per-capita expenditures were generally higher for those who were older, female, white, medically insured, or suffered from disc disorders.

CONCLUSIONS:   Health care expenditures for back pain in the United States in 1998 were substantial. The expenditures demonstrated wide variations among individuals with different clinical, demographic, and socioeconomic characteristics.

Lost Productive Time and Cost Due to Common Pain Conditions in the US Workforce
JAMA 2003 (Nov 12);   290 (18):   2443–2454 ~ FULL TEXT

The American productivity audit surveyed 29,000 working adults to quantify the impact of reduced performance at work due to pain. Researchers questioned respondents regarding the cost implications of reduced performance were due to headaches, arthritis, back pain and other musculoskeletal pain. Respondents were also asked if the common pain conditions had caused them to lose concentration, repeat jobs, do nothing or feel fatigued at work. The cost of lost productive time in the US workforce was found to be $61 billion, and 76% of that cost was attributed to health-related reduced performance. This is consistent with prior studies that concluded loss of productive time is more significant than absenteeism. The data revealed that 1.1% of the workforce were absent one or more days per week because of common pain conditions.

A hands-on approach to treating neck pain by manual therapy may help people get better faster and at a lower cost than more traditional treatments, according to this study.   After seven and 26 weeks, they found significant improvements in recovery rates in the manual therapy group compared to the other 2 groups. For example, at week seven, 68% of the manual therapy group had recovered from their neck pain vs. 51% in the physical therapy group and 36% in the medical care group.

The Cost-Effectiveness of Chiropractic

From:   Testimony to the Department of Veterans Affairs' Chiropractic Advisory Committee
George B. McClelland, D.C., Foundation for Chiropractic Education and Research ~ March 25, 2003

In the treatment of musculoskeletal disorders, despite the fact that most studies have not properly factored in such patient characteristics as severity and chronicity and lack the complete assessment of all direct costs and most indirect costs, the bulk of articles reviewed demonstrate lower costs for chiropractic. [9]   This pattern is consistently observed from the perspectives of workers' compensation studies, [10],   [11],   [12],   [13],   [14],   [15] databases from insurers, [16],   [17],   [18],   or the analysis of a health economist employed by the provincial government of Ontario. [19],   [20].

Other studies have suggested the opposite [that chiropractic services are more expensive than medical], [5],   [21],   [22]   but these contain significant flaws which have been refuted. [23]

The cost advantages for chiropractic for matched conditions appear to be so dramatic that Pran Manga, the aforementioned Canadian health economist, has concluded that doubling the utilization of chiropractic services from 10% to 20% may realize savings as much as $770 million in direct costs and $3.8 billion in indirect costs. [20]   When iatrogenic effects [yet to be discussed] are factored in, the cost advantages of spinal manipulation as a treatment alternative become even more prominent. In one study, for instance, it was shown that for managing disc herniations, the cost of treatment failures following a medical course of treatment [chymopapain injections] averaged 300 British pounds per patient, while there were no such costs following spinal manipulation. [24],   Imagine how failed back surgery might compare. Finally, in no cost studies to date have legal burdens been calculated, which one would expect should be heavily advantageous for chiropractic health management.

Chiropractic Treatment of Workers' Compensation Claimants in the State of Texas
MGT of America, Austin, Texas ~ February 2003

In 2002, the Texas Chiropractic Association (TCA) commissioned an independent study to determine the use and effectiveness of chiropractic with regard to workers' compensation, the results of which were published in February 2003. According to the report, chiropractic care was associated with significantly lower costs and more rapid recovery in treating workers with low-back injuries. They found: Lower back and neck injuries accounted for 38 percent of all claims costs. Chiropractors treated about 30 percent of workers with lower back injuries, but were responsible for only 17.5 percent of the medical costs and 9.1 percent of the total costs. These findings were even more intertesting: The average claim for a worker with a low-back injury was $15,884. However, if a worker received at least 75 percent of his or her care from a chiropractor, the total cost per claimant decreased by nearly one-fourth to $12,202.   If the chiropractor provided at least 90 percent of the care, the average cost declined by more than 50 percent, to $7,632.

Effects of Inclusion of a Chiropractic Benefit on the Utilization of
Health Care Resources in Managed Health Care Plan

Craig F Nelson, D.C., MS ~ 2003

A four-year longitudinal study using administrative claims data compared 700,000 health plan members with chiropractic coverage to 1 million health plan members without chiropractic coverage.   This study demonstrates that the inclusion of a chiropractic benefit in a managed health care plan results in a reduction in the overall utilization of health care resources, and thereby, cost savings.
There are four mechanism that produce this cost reduction:

  1. A favorable selection process;
  2. A substitution effect of chiropractic care for medical care;
  3. Lower rates of use of high cost procedures;
  4. Lower cost management of care episodes by chiropractors.

The current literature suggests that chiropractors and physicians provide equally effective care for OLBP but that chiropractic patients are more satisfied with their care. Evidence on the relative costs of medical and chiropractic care is conflicting. Several methodological deficiencies limit the validity of the reviewed studies. No studies combine high-quality cost data with adequate sample sizes and controls for confounding factors.

Single-blind Randomised Controlled Trial of Chemonucleolysis and
Manipulation in the Treatment of Symptomatic Lumbar Disc Herniation

European Spine Journal 2000 (Jun);   9 (3):   202-207

Crude cost analysis suggested an overall financial advantage from manipulation. Because osteopathic manipulation produced a 12-month outcome that was equivalent to chemonucleolysis, it can be considered as an option for the treatment of symptomatic lumbar disc herniation, at least in the absence of clear indications for surgery. In this study it was shown that for managing disc herniations, the cost of treatment failures following a medical course of treatment [chymopapain injections] averaged 300 British pounds per patient, while there were no such costs following spinal manipulation.

Economic Case for the Integration of Chiropractic Services into the Health Care System
J Manipulative Physiol Ther 2000 (Feb);   23 (2):   118-122 ~ FULL TEXT

For much of its history, chiropractic care has been both an alternative therapeutic paradigm and separate from or marginal to the mainstream health care system. Over the past decade, the situation has changed somewhat in that chiropractic care is gradually being integrated within a variety of health care delivery organizations. According to Triano et al,1 by the application of evidence-based health care and good business, there is a surge in cooperation and integration among chiropractors, allopathic physicians, allied health care providers, ancillary therapists, and respective support staff. There is, however, no quantification of the level of integration. Integration may also be more true of the United States than elsewhere. The overall position of chiropractic care as alternative and separate still predominates. This situation does not serve the interests of the chiropractic profession nor the public well. There is a persuasive economic case for a radical shift in the role of chiropractic care to one that may succinctly be described as alternative and mainstream.   The chiropractic profession must preserve its identity and its unique therapeutic paradigm and continue to be seen as an alternative to other health care professions, especially medical doctors. However, it should also become mainstream and thus widely available and accessible to the public by being integrated into the wide variety of health care delivery organizations that collectively constitute the health care system.

Studies on Chiropractic 2000
National Board of Chiropractic Examiners

Chiropractic is now firmly rooted in the public consciousness as a primary agent of health care management. According to a 1990 study published in the New England Journal of Medicine, the number of visits to non-medical health care providers in 1990 totaled 425 million, 9.5% more than the total number of visits to all family physicians (Eisenberg et al.1993). A follow-up study determined that, in 1997, total visits to non-medical providers amounted to 629 million, exceeding the total projected visits to all primary care physicians by 63% (Eisenberg et al. 1998). Moreover, a 1998 study published in the New England Journal of Medicine reported chiropractic as the most used non-medical treatment (15.7%) (Astin 1998).

Enhanced Chiropractic Coverage Under OHIP as a Means of Reducing Health Care Costs,
Attaining Better Health Outcomes and Achieving Equitable Access
to Select Health Services

Report to the Ontario Ministry of Health, 1998   PDF

Expenditure to improve access to chiropractic services, and the changed utilization patterns it produces, will lead to very substantial net savings in direct and indirect costs.   Direct savings to Ontario's health care system may be as much as $770 million, will very likely be $548 million, and will be at least $380 million.   The corresponding savings in indirect costs - made up of the short and long term costs of disability - are $3.775 billion, $1.849 billion and $1.255 billion.

Costs and Recurrences of Chiropractic and Medical Episodes of Low-back Care
J Manipulative Physiol Ther 1997 (Jan);   20 (1):   5-12

Total insurance payments within and across episodes were substantially greater for medically initiated episodes. Analysis of recurrent episodes as measures of patient outcomes indicated that chiropractic providers retain more patients for subsequent episodes, but that there is no significant difference in lapse time between episodes for chiropractic vs. medical providers. Chiropractic and medical patients were comparable on measures of severity; however, the chiropractic cohort included a greater proportion of chronic cases.

Chiropractic and Medical Costs of Low Back Care
Medical Care 1996 (Mar);   34 (3):   191-204

This study compares health insurance payments and patient utilization patterns for episodes of care for common lumbar and low back conditions treated by chiropractic and medical providers. Using 2 years of insurance claims data, this study examines 6,183 patients who had episodes with medical or chiropractic first-contact providers. Multiple regression analysis, to control for differences in patient, clinical, and insurance characteristics, indicates that total insurance payments were substantially greater for episodes with a medical first-contact provider.

The Outcomes and Costs of Care for Acute Low Back Pain Among Patients
Seen by Primary Care Practitioners, Chiropractors, and Orthopedic Surgeons

New England J Medicine 1995 (Oct 5);   333 (14):   913–917

The status at six months was ascertained for 1555 of the 1633 patients enrolled in the study (95 percent). The times to functional recovery, return to work, and complete recovery from low back pain were similar among patients seen by all six groups of practitioners, but there were marked differences in the use of health care services. The mean total estimated outpatient charges were highest for the patients seen by orthopedic surgeons and chiropractors and were lowest for the patients seen by HMO and primary care providers. Satisfaction was greatest among the patients who went to the chiropractors.

Preliminary Findings of Analysis of Chiropractic Utilization and Cost in the
Workers' Compensation System of New South Wales, Australia

J Manipulative Physiol Ther 1995 (Oct);   18 (8):   503-511

The methodology used was found to be able to provide a basis for comparison of costs for care apportioned to chiropractic and other interventions. An analysis of 20 randomly selected cases from the WCA suggested that chiropractic intervention for certain conditions may be more cost-effective than other forms of intervention.

Comparing the Costs Between Provider Types of Episodes of Back Pain Care
Spine (Phila Pa 1976) 1995 (Jan 15);   20 (2):   221-227

There were 1020 episodes of back pain care made by 686 different persons and encompassing 8825 visits. Chiropractors and general practitioners were the primary providers for 40% and 26% of episodes, respectively. Chiropractors had a significantly greater mean number of visits per episode (10.4) than did other practitioners.   Orthopedic physicians and "other" physicians were significantly more costly on a per visit basis. Orthopedists had the highest mean total cost per episode, and general practitioners the lowest.

Further Analysis of Health Care Costs for Chiropractic and Medical Patients
J Manipulative Physiol Ther 1994 (Sep);   17 (7):   442-446

The analysis of well-insured patients in plans that do not restrict the chiropractic benefit strengthens results previously reported. In this study, therefore,   the favorable cost patterns for chiropractic patients cannot be attributed to insurance restrictions limiting reimbursement for chiropractic services relative to other services. Because adjustments for patient characteristics systematically reduce the cost advantages of chiropractic patients as compared to mean differences derived from unadjusted data, the results also demonstrate that adjusted values should be used for meaningful comparisons between the two groups of patients.

A Comparison of Health Care Costs for Chiropractic and Medical Patients
J Manipulative Physiol Ther 1993 (Jun);   16 (5):   291-299

Nearly one-fourth of patients were treated by chiropractors.   Patients receiving chiropractic care experienced significantly lower health care costs as represented by third party payments in the fee-for-service sector. Total cost differences on the order of $1,000 over the 2-yr period were found in the total sample of patients as well as in subsamples of patients with specific disorders. The lower costs are attributable mainly to lower inpatient utilization. The cost differences remain statistically significant after controlling for patient demographics and insurance plan characteristics.

The Effectiveness and Cost-Effectiveness of Chiropractic Management of Low-Back Pain
Richmond Hill, Ontario: Kenilworth Publishing, 1993

A major study to assess the most appropriate use of available health care resources was reported in 1993. This was an outcomes study funded by the Ontario Ministry of Health. The study was conducted by three health economists led by University of Ottawa Professor Pran Manga, Ph.D. The report of the study is commonly called the Manga Report. The Manga Report overwhelmingly supported the efficacy, safety, scientific validity, and cost-effectiveness of chiropractic for low-back pain. Additionally, it found that higher patient satisfaction levels were associated with chiropractic care than with medical treatment alternatives.   On the evidence, particularly the most scientifically valid clinical studies, spinal manipulation applied by chiropractors is shown to be more effective than alternative treatments for LBP. It also found that many medical therapies are of questionable validity, or are clearly inadequate.

Comparisons of costs and outcomes were made between the two samples with the results being:
(i) a significantly lower number of claimants requiring compensation days when chiropractic management was chosen,
(ii) fewer compensation days taken by claimants who received chiropractic management,
(iii) a greater number of patients progressed to chronic status when medical management was chosen, and
(iv) a greater average payment per claim with medical management.

A Comparison of the Cost of Chiropractors Versus Alternative Medical Practitioners
Richmond, VA: Virginia Chiropractic Association, 1992

A 1992 study conducted by L.G. Schifrin, Ph.D., provided an economic assessment of mandated health insurance coverage for chiropractic treatment within the Commonwealth of Virginia. As reported by the College of William and Mary, and the Medical College of Virginia, the study indicated that chiropractic provides therapeutic benefits at economical costs. The report also recommended that chiropractic be a widely available form of health care. This paper is unavailable through PubMed or the Mantis database.

Cost Per Case Comparison of Back Injury Claims of Chiropractic Versus

This workers’ compensation study conducted in Utah compared the cost of chiropractic care to the costs of medical care for conditions with identical diagnostic codes. The study indicated that costs were significantly higher for medical claims than for chiropractic claims. The sample consisted of 3062 claims or 40.6% of the 7551 estimated back injury claims from the 1986 Workers' Compensation Fund of Utah.   For the total data set, cost for care was significantly more for medical claims, and compensation costs were 10-fold less for chiropractic claims.

Disabling Low Back Oregon Workers' Compensation Claims. Part I:
Methodology and Clinical Categorization of Chiropractic and Medical Cases

J Manipulative Physiol Ther 1991 (Mar);   14 (3):   177-184

The two provider groups differed in the proportion of claimants who had physical factors contributing to low back compromise.   DC claimants were less likely than MD claimants to have sought initial treatment in the emergency room, more likely to have a history of chronic, recurrent low back pain and more likely to have suffered exacerbation episodes. These differences suggest a greater level of chronicity among chiropractic claimants.

Disabling Low Back Oregon Workers' Compensation Claims Part II: Time Loss
J Manipulative Physiol Ther 1991 (May);   14 (4):   231-239

for claimants with a history of chronic low back problems,   the median time loss days for MD cases was 34.5 days, compared to 9 days for DC cases. It is suggested that chiropractors are better able to manage injured workers with a history of chronic low back problems and to return them more quickly to productive employment.

Disabling Low Back Oregon Workers' Compensation Claims Part III:
Diagnostic and Treatment Procedures and Associated Costs

J Manipulative Physiol Ther. 1991 (Jun);   14 (5):   287-297

Claimants in Oregon with disabling low back injuries attending chiropractors were found to have more treatments over a longer duration and at greater cost than claimants attending medical physicians with similar clinical presentations. These findings are attributed to: a) a higher proportion of chiropractic claimants than medical physician claimants with low back risk factors which may have adversely affected the course of recovery (chronic or recurrent low back conditions, obesity, extremity symptomatology, frequency of exacerbations); b) differences in age and gender of DC and MD claimants; c) the greater physician-patient contact hours characteristic of chiropractic practice; d) differences in therapeutic modalities employed; and e) the physician reimbursement permitted under Oregon workers' compensation law. The findings of this study emphasize the need for prospective studies of treatment outcome.

For those who received care from DCs (n = 266), the mean number of compensated days lost from work was at least 2.3 days less than for those who were treated by MDs (n = 494; p less than 0.025) and at least 3.8 days less than for those who were treated by DOs (n = 102; p less than 0.025).   Consequently, much less money in employment compensation was paid, on the average, to those who saw DCs.

An Analysis of Florida Workers' Compensation Medical Claims for Back-related Injuries
Journal of the American Chiro Association 1988;   25 (7):   50-59

This study of 10,652 Florida Workers’ Compensation cases was conducted by Steve Wolk, Ph.D. , and reported by the Foundation for Chiropractic Education and Research. It was concluded that   “a claimant with a back-related injury, when initially treated by a chiropractor versus a medical doctor, is less likely to become temporarily disabled, or if disabled, remains disabled for a shorter period of time; and claimants treated by medical doctors were hospitalized at a much higher rate than claimants treated by chiropractors.” The analysis focused on the cost of treatment, frequency of compensable injuries (an injury which disables an individual for more than seven days, resulting in wage compensation benefits), and frequency of hospitalization for workers' compensation claim patient (end of reference).

Educational Deficiencies in Musculoskeletal Medicine
Journal of Bone and Joint Surgery 2002 (Apr);   84-A (4):   604-608

According to the standard suggested by the program directors of internal medicine residency departments, a large majority of the examinees once again failed to demonstrate basic competency in musculoskeletal medicine on the examination. It is therefore reasonable to conclude that medical school preparation in musculoskeletal medicine is inadequate. NOTE: This is a follow-up article to the study cited below, which demonstrated that medical students were inadequately trained to diagnose and treat musculoskeletal complaints. Ask yourself: What would the headlines scream if, after 4 years, chiropractors had failed to improve their skills in musculoskeletal assessment and management? Why is medicine is shown more slack?

This is the original article, which found that 82 per cent of medical school graduates failed a valid musculoskeletal competency examination. They concluded that "we therefore believe that medical school preparation in musculoskeletal medicine is inadequate" and that medical students were inadequately trained to diagnose and treat musculoskeletal complaints.

Educating Medical Students About Musculoskeletal Problems: Are
Community Needs Reflected in the Curricula of Canadian Medical Schools?

Journal of Bone and Joint Surgery 2001 (Sept);   83-A (9):   1317-1320

Musculoskeletal problems are a common reason why patients present for medical treatment. The purpose of the present study was to review the curricula of Canadian medical schools to determine whether they prepare their students for the demands of practice with respect to musculoskeletal problems. The curriculum analysis revealed that, on the average, medical schools in Canada devoted 2.26% (range, 0.61% to 4.81%) of their curriculum time to musculoskeletal education. Our literature review and survey of local family physicians revealed that between 13.7% and 27.8% of North American patients presenting to a primary care physician have a chief symptom that is directly related to the musculoskeletal system. (So they conclude:) There is a marked discrepancy between the musculoskeletal knowledge and skill requirements of a primary care physician and the time devoted to musculoskeletal education in Canadian medical schools.

A Comparison of Chiropractic Student Knowledge Versus Medical Residents
Proceedings of the World Federation of Chiropractic Congress 2001 Pgs. 255

A previously published knowledge questionnaire designed by chief orthopedic residents was given to a Chiropractic student group for comparison to the results of the medical resident group. Based on the marking scale determined by the chief residents, the Chiropractic group (n = 51) showed statistically significant higher average grade than the orthopedic residents. Expressed in other terms, 70% of chiropractic students passed the knowledge questionnaire, compared to an 80% failure rate for the orthopedic residents.

Musculoskeletal Knowledge: How Do You Stack Up?
Physician and Sportsmedicine 2002; 30 (8) August

One of every 4 or 5 primary care visits is for a musculoskeletal problem. Yet undergraduate and graduate training for this burden of illness continues to constitute typically less than 5% of the medical curriculum. This is an area of clear concern, but also one in which sports medicine practitioners can assume leadership.

It's 8:00 pm on a Monday night. Just as you're getting ready to put your 5-year-old son to bed, he falls from a chair, landing on his wrist. It quickly swells, requiring a visit to a nearby urgent care clinic. At the clinic, a pleasant young resident takes a history, performs a physical exam, and orders an x-ray to evaluate the injury. You are told that nothing is broken, and a wrist splint is placed. The following day, however, you receive a phone call from the clinic informing you that upon further review of the radiographs, a fracture was detected, and your son will need a cast for definitive treatment. This scenario, while fictitious, is not unusual. According to some studies, up to 10% of wrist fractures are missed at the initial evaluation.1 While pediatric fractures are often difficult to detect, this example highlights a problem that continues to plague medical education: inadequate instruction in musculoskeletal medicine in both medical school and residency training.

In this study, 334 medical students, residents and staff physicians, specializing in various fields of medicine, were asked to take a basic cognitive examination consisting of 25 short-answer questions - the same type of test administered in the original JBJS 1998 study. The average score among medical doctors, students and residents who took the exam in 2005 was 2.7 points lower than those who took the exam in 1998. Just over half of the staff physicians (52%) scored a passing grade or higher on the 2005 exam. Only 21% of the residents registered a passing grade, and only 5% of the medical students passed the exam. Overall, Seventy-nine percent of the participants failed the basic musculoskeletal cognitive examination.

More Evidence of Educational Inadequacies in Musculoskeletal Medicine

A modified version of an exam used to assess the competency of incoming interns at the University of Pennsylvania was used to assess the competency of medical students during various stages of their training at the University of Washington. Despite generally improved levels of competency with each year at medical school, less than 50% of fourth-year students showed competency. These results suggested that the curricular approach toward teaching musculoskeletal medicine at this medical school was insufficient and that competency increased when learning was reinforced during the clinical years.

The National Board of Chiropractic Examiners published reports based on a four-year study of chiropractic.  These reports  focused on  three surveys including  full-time, licensed U.S., Canadian and registered Australian and New Zealand chiropractic practitioners.  The surveys and their resulting reports are titled Job Analysis of Chiropractic.

Following publication of the Job Analysis of Chiropractic, the NBCE began to receive requests for permission to reproduce certain portions of the reports.  In response to those requests, the NBCE has condensed relevant portions and reprinted them in this brochure.

In recent years, numerous independent researchers and various government agencies  have conducted studies which focus  on the efficacy, appropriateness and cost-effectiveness of chiropractic treatment.   Several of these important studies are listed below.

  • A 1994 study published by the U.S. Agency for Health Care Policy and Research (AHCPR) and the U.S. Department of Health and Human Services   endorses spinal manipulation for acute low back pain in adults in its Clinical Practice Guideline # 14.  An independent multidisciplinary panel of private-sector clinicians and other experts convened and developed specific statements on appropriate health care of acute low back problems in adults.   One statement cited,  relief of discomfort (low back pain) can be accomplished most safely with spinal manipulation, and/or nonprescription medication.

  • A major study to assess the most appropriate use of available health care resources was reported in 1993.  This was an outcomes study funded by the Ontario Ministry of Health and conducted in hopes of sharing information about ways to reduce the incidence of work-related injuries and to address cost-effective ways to rehabilitate disabled and injured workers. The study was conducted by three health economists led by University of Ottawa Professor Pran Manga, Ph.D.  The report of the study is commonly called the Manga Report.  The Manga Report overwhelmingly supported the efficacy, safety, scientific validity, and cost-effectiveness of chiropractic for low-back pain.  Additionally, it found that higher patient satisfaction levels were associated with chiropractic care than with medical treatment alternatives.

    "Evidence from Canada and other countries suggests potential savings of hundreds of millions annually,"
    the Manga Report states.

    "The literature clearly and consistently shows that the major savings from chiropractic management come from fewer and lower costs of auxiliary services, fewer hospitalizations, and a highly significant reduction in chronic problems, as well as in levels and duration of disability."

  • A four-phase study conducted in the early 1990s by RAND, one of America's most prestigious centers for research in public policy, science and technology, explored many indications of low-back pain.  In the RAND studies, an expert panel of researchers, including medical doctors and doctors of chiropractic, found that:

    • chiropractors deliver a substantial amount of health care to the U.S. population.

    • spinal manipulation is of benefit to some patients with acute low-back pain.

    The RAND reports marked the first time that representatives of the medical community went on record stating that spinal manipulation is an appropriate treatment for certain low-back pain conditions.

  • A 1988 study of 10,652 Florida workers' compensation cases was conducted by Steve Wolk, Ph.D. , and reported by the Foundation for Chiropractic Education and Research (FCER). It was concluded that "a claimant with a back-related injury, when initially treated by a chiropractor versus a medical doctor, is less likely to become temporarily disabled, or if disabled, remains disabled for a shorter period of time; and claimants treated by medical doctors were hospitalized at a much higher rate than claimants treated by chiropractors." Some of the study results were:

    • 51.3 percent shorter temporary total disability duration with chiropractic care

    • lower treatment cost by 58.8 percent ($558 vs. $1,100 per case) in the chiropractic group, and

    • 20.3 percent hospitalization rate in the chiropractic care group vs. 52.2 percent rate in the medical care group

  • In 1989, a survey administered by Daniel C. Cherkin, Ph.D., and Frederick A. MacCornack, Ph.D., concluded that patients receiving care from health maintenance organizations (HMOs) within the state of Washington were three times as likely to report satisfaction with care from chiropractors as they were with care from other physicians. The patients were also more likely to believe that their chiropractor was concerned about them.

  • A workers' compensation study conducted in Utah by Kelly B. Jarvis, D.C., Reed B. Phillips, D.C., Ph.D., and Elliot K. Morris, JD, MBA, compared the cost of chiropractic care to the costs of medical care for conditions with identical diagnostic codes.  Results were reported in the August 1991 Journal of Occupational MedicineThe study indicated that costs were significantly higher for medical claims than for chiropractic claims; in addition, the number of work days lost was nearly ten times higher for those who received medical care instead of chiropractic care.

    This Compensation Board study found the total treatment costs for back-related injuries cost an average of $775.30 per case when treated by a doctor of chiropractic. When injured workers received standard medical treatment as opposed to chiropractic treatment, the average cost per case was $1,665.43. They also found the mean compensation cost paid out by the Utah Worker's Compensation Board for patients treated by medical doctors was $668.39, while the mean compensation cost paid for patients treated by chiropractic doctors was only $68.38.

  • A 1992 article in the Journal of Family Practice reported a study by DC Cherkin, Ph.D., which compared patients of family physicians and of chiropractors.   The article stated "the number of days of disability for patients seen by family physicians was significantly higher (mean 39.7) than for patients managed by chiropractors (mean 10.8)." A related editorial in the same issue referred to risks of complications from lumbar manipulation as being "very low."

  • Miron Stano, PhD, a health care economist at Oakland University, conducted a study comparing the health-care costs for chiropractic and medical patients with neuromusculoskeletal conditions. The database he used came from the records of MEDSTAT Systems, Inc., a health benefits management consulting firm which processes insurance claims for many of the country's largest corporations. This June 1993 Journal of Manipulative and Physiological Therapeutics study involved 395,641 patients, drawn from statistical information on more than two million beneficiaries. Results over a two-year period showed that patients who received chiropractic care incurred significantly lower health care costs than did patients treated solely by medical or osteopathic physicians.

    Also of interest, for those patients receiving both medical and chiropractic care, the Stano/MEDSTAT results revealed:

    • 31 percent lower hospital admissions rates;

    • 43 percent lower inpatient payments; and

    • 23 percent lower total health care costs.

  • Following a 1993 study, researchers J. David Cassidy, D.C., Haymo Thiel,   D.C., M.S., and W. Kirkaldy-Willis, M.D., of the Back Pain Clinic at the Royal University Hospital in Saskatchewan concluded that "the treatment of lumbar intervertebral disk herniation by side posture manipulation is both safe and effective."

  • In 1985 the University of Saskatchewan conducted a study of 283 patients "who had not responded to previous conservative or operative treatment" and who were initially classified as totally disabled. The study revealed that "81% ... became symptom free or achieved a state of mild intermittent pain with no work restrictions" after daily spinal manipulations were administered.

  • A 1978 study conducted by J.S. Wight, D.C. , and reported in the ACA Journal of Chiropractic, indicated that 74.6% of patients with recurring headaches, including migraines, were either cured or experienced reduced headache symptomatology after receiving chiropractic manipulation.

  • 1991 GALLUP POLL
  • A 1991 demographic poll conducted by the Gallup Organization revealed that 90% of chiropractic patients felt their treatment was effective; more than 80% were satisfied with that treatment; and nearly 73% felt most of their expectations had been met during their chiropractic visits.

  • A 1992 review of data from over 2,000,000 users of chiropractic care in the U.S., reported in the Journal of American Health Policy, stated that "chiropractic users tend to have substantially lower total health care costs," and that "chiropractic care reduces the use of both physician and hospital care."

  • In 1985 the University of Saskatchewan conducted a study of 283 patients "who had not responded to previous conservative or operative treatment" and who were initially classified as totally disabled. The study revealed that "81% ... became symptom free or achieved a state of mild intermittent pain with no work restrictions" after daily spinal manipulations were administered.

Further validation of chiropractic care evolved from an antitrust suit which was filed by four members of the chiropractic profession against the American Medical Association (AMA) and a number of other health care organizations in the U.S. (Wilk et al v. AMA et al, 1990).   Following 11 years of litigation, a federal appellate court judge upheld a ruling by U.S. District Court Judge Susan Getzendanner that the AMA had engaged in a "lengthy, systematic, successful and unlawful boycott" designed to restrict cooperation between MDs and chiropractors in order to eliminate the profession of chiropractic as a competitor in the U.S. health care system.

Judge Getzendanner rejected the AMA's patient care defense, and cited scientific studies which implied that "chiropractic care was twice as effective as medical care in relieving many painful conditions of the neck and back as well as related musculo-skeletal problems."   Since the court's findings and conclusions were released, an increasing number of medical doctors, hospitals, and health care organizations in the U.S. have begun to include the services of chiropractors.

In order to become a licensed doctor of chiropractic, an individual must meet stringent testing, academic and professional requirements.  Currently, an individual must complete the four major steps shown below in order to become a chiropractic practitioner:


Government inquiries (some of which are described in this brochure), as well as independent investigations by medical practitioners, have affirmed that today's chiropractic academic training is of equivalent standard to medical training in all pre-clinical subjects.   High standards in chiropractic education are maintained by the Council on Chiropractic Education (CCE) and its Commission on Accreditation, as recognized by the U.S. Department of Education.

Some Chiropractic colleges require a Bachelor's degree before enrollment.   A doctor of chiropractic's training generally requires a minimum of six years of college study (two years of which are undergraduate course work) and an internship prior to entering practice.   Post-doctoral training in a variety of clinical disciplines and specialties is also available through accredited colleges and specialty councils.


Chiropractic is one of many occupations which are regulated by state licensing agencies. The requirements for chiropractic licensure vary from state to state (and country to country).  Some states require a Bachelor's degree as a prerequisite for licensure.  To assist the various regulatory agencies in assessing candidates for licensure, the National Board administers examinations to individuals currently in the chiropractic educational system or who have completed a chiropractic educational program. The National Board also offers an examination designed for previously licensed individuals.

A candidate for chiropractic licensure may request that transcripts of scores from National Board examinations be forwarded to licensing agencies which assess eligibility for licensure.  Scores from National Board examinations are made available to licensing agencies throughout the U.S. and in some foreign countries including Canada, the United Kingdom, France and Australia.
