Background:   A definitive diagnosis in chiropractic clinical practice is frequently elusive, yet decisions around management are still necessary. Often, a clinical impression is made after the exclusion of serious illness or injury, and care provided within the context of diagnostic uncertainty. Rather than focussing on labelling the condition, the clinician may choose to develop a defendable management plan since the response to treatment often clarifies the diagnosis.

Discussion:   This paper explores the concept and elements of defensive problem-solving practice, with a view to developing a model of agile, pragmatic decision-making amenable to real-world application. A theoretical framework that reflects the elements of this approach will be offered in order to validate the potential of a so called '3-Questions Model';

Summary:   Clinical decision-making is considered to be a key characteristic of any modern healthcare practitioner. It is, thus, prudent for chiropractors to re-visit the concept of defensible practice with a view to facilitate capable clinical decision-making and competent patient examination skills. In turn, the perception of competence and trustworthiness of chiropractors within the wider healthcare community helps integration of chiropractic services into broader healthcare settings.

From the FULL TEXT Article:

Development of the 3-questions Model

The chiropractic profession, particularly in Western countries, finds itself in a rapidly evolving healthcare landscape, with ‘modernisation’ being a consequence of escalating costs, an aging population, and an ever-diminishing relative resource base [9]. With a view to rationalising resources health system decision-makers are increasingly vigilant about the delivery of safe, evidence-based, cost-effective care, summarised as “the right care at the right time in the right place” [10, 11]. With this imperative in mind, the authors propose three straightforward questions that frame clinical decision-making within the context of diagnostic uncertainty.

Question 1:   What is the likelihood I will delay access to more appropriate care for this patient?

Contemporary chiropractic offers an array of conservative treatments, selected and delivered on the basis of research evidence, tradition, expertise, patient preference, or a combination of all these. Yet, before any treatment can be applied, the practitioner has a duty of care to ensure that the patient will receive the most appropriate care at the right time, which may in fact necessitate referral to another healthcare provider. In other words, the preferences, traditions, and care philosophy of the practitioner are secondary to the needs of the patient, supported by the maxim; ‘first do no harm’ [12, 13]. In short, the practitioner must consider what has gone wrong with the patient as a whole to bring them to this point, and what role the chiropractor may play in their management [12].

The favourable natural history and episodic nature of uncomplicated spine-related disorders, the well documented ‘Hawthorne Effect’, combined with a low risk of adverse effects, may lull the chiropractor into a false belief that their favoured technique provides a panacea [14]. Indeed, the belief that simply finding, quantifying and addressing ‘subluxations’ is the only role of the chiropractor ignores the reality that patients with serious or life threatening conditions can, and do, present to chiropractors. Also, over-confidence in their care philosophy and treatment technique may lead to the inappropriate treatment of specific patient populations. The failure to recognise these and consequently refer constitutes a significant proportion of malpractice litigation against chiropractors [15].

Chiropractors, along with all other health professionals, must be vigilant concerning the so called ‘Red Flags’ for serious illness, and be familiar with the signs and symptoms of emerging ill health or injury (13). Therefore, the practitioner must make several decisions on behalf of each patient on each visit. Firstly; whether the patient can be managed without collaboration with any other health practitioner, secondly; if the patient should be managed in conjunction with other healthcare provider(s), or thirdly; whether the patient should be rejected outright for chiropractic care.

It is relevant to note that various regulatory bodies expect inter-professional relationships to exist in the best interest of the patient, for example:

The Australian Code: Section 5

5.1 Good care is enhanced when there is mutual respect and clear communication between all health professionals involved in the care of the patient [16].

The UK code: Section D1

b)   Identifying where it might be appropriate to consider co-managing the patient with another healthcare practitioner

c)   Referring patients to other healthcare practitioners when their needs are beyond your own knowledge, skills and competence [17].

Question 2:   Is my proposed treatment safe? (What is the likelihood of making this patient worse?)

The risk of adverse events with chiropractic care is enviably low. Even those sceptical of chiropractors and spinal manipulation admit that adverse side effects after chiropractic spinal manipulation are usually mild and transient [18, 19]. Combined with high levels of patient satisfaction, the low risk of manual and manipulative therapy reinforces the role of chiropractic in the management of spine-related disorders [20, 21]. Consequently, spinal manipulation is now recommended for consideration in recent guidelines for management of uncomplicated spinal pain [8].

Chiropractic practice embraces a broad clinical spectrum including manual, manipulative, soft-tissue, physiological and rehabilitative therapies – choosing which of these to apply, and when, have evolved over time as part of the so called ‘Art of Chiropractic’. Based on the likely anatomical source of the presenting complaint, the chiropractor must advise the most appropriate clinical intervention, in the best interest of the patient [12].

Again, it is pertinent to note the requirements of regulators, whereby chiropractors must follow a patient-centred approach that minimises the risk of harm. Question 2 ensures compliance with the following sections:

The Australian code: Section 2.2 Good Care

d)   Practising patient-centred care, including encouraging patients to take interest in, and responsibility for the management of their health and supporting them in this

f)   Considering the balance of benefit and harm in all clinical management decisions [16].

The UK Code: S2.6 Clinical decision making

When drawing up the working diagnosis or rationale for care, you must consider:

a)   Relevant information about the natural history and prognosis of any complaint the patient has

b)   The potential benefits and risks of care, including contraindications

c)   The likelihood of recurrence or need for long-term management [17].

Question 3:   Do I have all the information I need to answer the first two questions?

Cleland describes the concept of a ‘treatment threshold’, whereby the clinician gathers information from the health history and the physical examination and further tests until they decide whether or not to provide care for the patient [22]. For the chiropractor, this is not as simple as checking they are breathing and have a spine! The health history and subsequently the relative value of findings from physical examination, orthopaedic tests, and available technologies are assessed according to sensitivity and specificity. Synthesis of the information gathered through history-taking, examination and evaluation of the patient is necessary to formulate a clinical impression, even if the diagnostic context is uncertain. Matters of safety, appropriateness, and cost-effectiveness of treatment are all paramount in the decision-making process and gathering information via thorough patient assessment permits the answering of the third question [23, 24].

The Australian Code: Section 4.2 Good practice involves

a)   A full and thorough assessment of patients using tools, tests and procedures that are appropriate for the gathering of information necessary to form a reasonable diagnosis [16].

The UK Code: S2.6 Clinical decision making

You must:

a)   Evaluate the patient’s health and health needs

b)   Arrive at and document a working diagnosis or rationale for care, based on the evaluation of the information.

Groopman (2007) advises patients to ask their doctor three pertinent questions which astute chiropractic practitioners would do well to ask themselves on behalf of their patient;

“What else could it be?”,

“Is there anything that doesn’t fit?” and

“Is it possible there is more than one problem?”

The patient may well in the chiropractors’ opinion, have a biomechanical (functional) spinal lesion, but what else might they have? [25,26] Thus, the imperative of the clinical encounter is to ensure the patient is in the right place at the right time; more appropriate care is not likely to be delayed, the intervention is not likely to result in harm, and the clinician has enough information to decide. If the cause of the presentation can be labelled (diagnosed), are there co-morbidities, and if so are they significant? The context of the clinical decision is “what are the ramifications of being incorrect?” Notwithstanding the traditional chiropractic emphasis on specificity, the reality is the implications for the patient are greater if the clinician ‘misses’ serious illness or injury compared to making an incorrect MSK diagnosis.


Red Flags for Care

Thanks to David Murphy, MD

Defined as a clinical sign or symptom that may indicate sinister pathology as the source of LBP, most red flags can be identified during a careful history.

The following is a list of sinister conditions and their associated red flags:

Malignancy:   (<1%): elderly, pain worse at night and not relieved by recumbancy, weight loss, chills, fever, night sweats

Infection:   (.01%): chills, fever, night seats, compromised host (diabetic, chronically ill ), IV drug use, previous UTI, skin infection or spinal procedure

Spinal fracture:   (<1%): history of trauma or osteoporosis

Cauda equina syndrome:   saddle anesthesia, incontinence of urine/stool

Spondyloarthropathies:   (<1%) (Rieter’s Syndrome, ankylosing spondylitis): inflammatory bowel disease, am stiffness, age < 40, improvement with exercise

Visceral disease:   (2%): include abdomenal aneurism, PID, peptic ulcer disease, endometriosis, ectopic pregnancy, tenderness or mass on abdomenal exam

Yellow Flags for Care

Sometimes we make the right diagnosis and provide appropriate treatment but the lower back pain doesn’t significantly decrease. Yellow flags are items in case presentation that can alert us to the possibility of delayed healing. These factors need to be considered in order to avoid chronicity. Some need to be addressed before treatment begins.

Yellow Flags in History and Examination:

  • Non-localized pain
  • Previous episodes of low back pain
  • Delay in getting treatment
  • Symptoms lasting more than three months
  • Pain intensity of greater than 8/10 three weeks or more after onset
  • Positive findings on neurological exam
  • Positive findings on orthopedic exam
  • Poor sleep (less than six hours/night)
Non-organic yellow flags:
  • Anxiety
  • Depression
  • Three or more positive Waddell signs
  • Negative family life
  • Negative work environment
  • Receiving compensation
  • Anticipation of future disability
  • Litigation
  • Prior work disability

The 3-questions model of clinical decision making for chiropractors

  1. What is the likelihood I will delay access to more appropriate care for this patient?

  2. Is my proposed treatment safe? (What is the likelihood of making this patient worse?)

  3. Do I have enough information to answer the first two questions?

The chiropractic profession is now highly regulated in developed countries, with standards that demand competent, safe practice and a duty of care to each and every patient. Logically, if chiropractors demonstrate these attributes, their reputation and trustworthiness is enhanced within the healthcare community, facilitating the future integration of chiropractic services into multidisciplinary healthcare settings. The Australian Productivity Commission’s Australia’s Health Workforce Report (2005) contains far-reaching recommendations related to national regulation and registration, workforce rationalisation, and an evolution of the role of all health professionals, with these recommendations driving healthcare transformation [27]. In fact, this transformation is arguably a revolution and presents as an opportunity for chiropractors to potentially take on a more generic role within this ‘task substitution’, in line with the healthcare workforce requirements of the future [28, 29]. In the opinion of the authors this requires a clear demarcation in the role of the chiropractor: being cognisant of differentiation between ‘primary contact’ and ‘primary care’.

The competence of chiropractors to arrive at a meaningful diagnosis remains a somewhat controversial topic. It is well-documented that chiropractors outperform other health professionals in musculoskeletal competence, however, their role in making accurate, crossprofessionally relevant diagnoses, in areas other than musculoskeletal health is less clear [30, 31]. The ruling in a recent court case in Texas illustrates an interesting paradox [32]. The opinion of the judge that chiropractors could only make a diagnosis in the context of musculoskeletal/biomechanical conditions at first reading is seemingly in contrast to the UK and Australian chiropractic regulatory agencies, where a chiropractor may be disciplined for failing to make a diagnosis [16, 17]. However, this may not be as inconsistent with the traditional role of chiropractors as it first seems. The chiropractor is not expected, and should not make a diagnosis outside their scope of practice; this is generally the role of the medical practitioner.

The need is emphasised for chiropractors to adopt a consistent decision-making process where the information gathered from patient assessment is synthesised in order to make reasonable judgements about appropriateness and safety of care, particularly when a diagnosis is equivocal. In these circumstances the clinical imperative may not be about having the right diagnosis, but rather about generating a defensible patient management plan and making prompt referral when necessary - this is the context in which the 3-Questions Model may be helpful to practitioners.

The 3 Questions Model

In short, the authors’ contend that while chiropractors should always aim to make as accurate a diagnosis as possible within their scope of practice, recognise this is often not achievable. The focus rather is on forming a defendable clinical rationale for management. This presupposes exclusion of those patients outside the clinical remit. This defensive methodology is given further traction by Haldeman (2011) who suggests that “by discarding the term diagnosis, we may be able to spare patients extensive and expensive testing that leads to findings that do not correlate with each other and that do not allow for any generally agreedon treatment approach” [33]. Society and regulators expect chiropractors to practice safely and competently within their scope of chiropractic practice - this scope of care has traditionally consisted of spinal care that excluded pharmacological or surgical prescription [34-36]. The observations of Catto (2005) offered as the introduction to this paper whilst uttered in reference to medical practitioners are none-the-less certainly relevant to chiropractors.


Clinical decision-making is without doubt a key characteristic of any modern healthcare practitioner. It is prudent for chiropractors to re-visit the concept of competent, defensible practice with a view to facilitate clinical decision-making and patient examination skills within the profession. In turn, this improves the reputation and perceived trustworthiness of chiropractors among healthcare providers and facilitates the integration of chiropractic services into broader healthcare settings. Adept clinical decision-making, even when a definitive diagnosis is elusive, should be the hallmark of chiropractic practice, consequently ensuring that patients are managed safely and appropriately. Thus, the 3-Questions Model as described in this paper is proposed as a reference-point for pragmatic decision-making by chiropractors.
