Part III: Conclusion, Appendixes, Glossary, and Index
Conclusion
This report has covered a broad spectrum of
alternative medical therapies and systems of medicine. Some of
these medical systems, such as Ayurvedic medicine and traditional
oriental medicine, are centuries old and are still in extensive
use in other nations and cultures of the world. Others, such as
osteopathy and naturopathy, evolved in the United States in the
not-too-distant past but were relegated to the fringes of
medicine because they differed from conventional biomedicine in
the concepts of health and illness they embraced. Still others,
such as some of the mind-body and bioelectromagnetic approaches,
are on the frontier of scientific knowledge and understanding.
Many alternative practitioners face numerous
economic, political, and scientific barriers that block their
acceptance by mainstream biomedicine. On the other hand, some
alternative medical practitioners do not expect to be brought
into the fold. Rather, they just want the opportunity to coexist
peacefully with mainstream medical practitioners and to be
allowed to offer consumers alternative health care options.
Consumers, however, are not waiting for mainstream science to
give them a "green light" on many alternative
treatments before using them. The fact is that today alternative
medicine constitutes a significant and growing portion of the
Nation's health care expenditures.
Recent surveys have demonstrated that most
people who opt to use alternative treatments or systems of
medicine believe that conventional medicine has not adequately
addressed their needs, or they want to supplement and thus
improve on their conventional treatment. This is especially true
of people with chronic, debilitating illnesses such as arthritis,
pain, cancer, and AIDS. People often are attracted to alternative
medicine practitioners who emphasize the patient's role in the
healing process as well as the importance of the
patient-practitioner interaction.
Studies also show that individuals who seek out
and use alternative medical treatments tend to be the better
educated and the more affluent. Thus the stereotype of the
alternative medicine consumer as an uneducated, poor person
succumbing to the sideshow lures of quacks and charlatans appears
to be greatly overblown. The reality is that because patients, in
general, are demanding more health care options at a lower cost,
a growing number of conventionally trained American physicians
have already begun incorporating alternative medical modalities
into their everyday medical practices.
The dominant biomedical U.S. health care system
has made countless technological discoveries and innovations in
the past half century, revolutionizing the way the body, the
mind, and the environment are viewed. By all measures, however,
it is an extremely expensive system offering limited
accessibility. In other words, the patients who have the most
money and live nearest the best health care facilities often
receive the best care. Increasingly, this situation will dictate
that the elderly, the disadvantaged, people with chronic
illnesses, and the very young go without adequate health
care--the populations that need health care most.
One of the simplest and most effective ways to
significantly lower health care costs and thus increase access is
through a major focus on preventive medicine. In this clinical
arena, many of the alternative health care systems may have much
to offer. Homeopathic and naturopathic physicians, for example,
strongly advise their patients about diet and other
health-promoting lifestyle choices as a matter of routine care.
In contrast, many conventional physicians do not routinely give
such advice until a patient has already become chronically ill,
by which time the patient may need expensive high-tech surgery
and face a lifetime of expensive drug therapy.
Another major factor contributing to the
skyrocketing health care costs in this country is the amount of
time involved in officially certifying a drug or medical
intervention as clinically effective and safe. Millions of
dollars may be spent, and years may pass, before a potentially
lifesaving drug, instrument, or intervention winds its way
through the complex Federal approval process. That same process
too often ignores or discounts related, potentially valuable
Canadian, European, and Asian data that could significantly
shorten the assessment process.
In addition, standards of testing drugs and
therapies in the United States are inconsistent with standards in
many other technologically developed countries. For example, U.S.
regulations on testing herbal medicines require a much more
circuitous testing process than is required overseas. There,
evidence of prior use without adverse side effects may be
accepted by medical authorities without data from extensive
clinical trials; preliminary clinical trials can therefore focus
immediately on the effectiveness of the herbal remedy. In the
United States, however, Phase I trials focus solely on safety
issues, and effectiveness is not dealt with until much later.
Furthermore, in many European and Asian
countries it is completely acceptable to test an herbal extract
as a single drug rather than require every potentially active
ingredient in the plant to be tested, as is the rule in the
United States. Thus in other developed countries significantly
less time and cost often are involved in bringing a potentially
beneficial herbal or naturally occurring remedy to market.
As U.S. consumers continue to use alternative
medicine, the challenge for health care policymakers and Federal
regulators is not only to protect the public from unscrupulous
medical practitioners but also to ensure the public's access to
the most effective treatments available. Certainly, patients
should have recourse if it can be shown that their practitioners
or the treatments they offer have no clinical or psychological
benefit. By the same token, patients with debilitating severe or
chronic illnesses should have the right to have access to--as
well as insurance to cover--an alternative therapy they believe
offers them relief.
Many of the alternative therapies described and
discussed in this report--hypnosis, art therapy, music therapy,
chiropractic, massage therapy, acupuncture, and many herbal and
nutritional supplementations, to name a few--have already
received extensive and positive clinical evaluations. However, no
critical mass of researchers, clinicians, and policymakers has
formed to give them more exposure and recognition. Therefore,
many of these therapies should be included in any serious
discussions about developing a truly comprehensive health care
system. Others, as the report has indicated, need to be quickly
and thoroughly evaluated before any judgment can be passed.
However, they still may represent a great and largely untapped
resource for improving the Nation's health.

Appendix B: Comments of the Panel on Mind-Body Interventions
on the National Research Council's Reports on Alternative
Medicine
In 1991 the National Research Council (NRC)
issued an evaluation of some of the therapies examined herein
(Druckman and Bjork, 1991). The NRC in 1988 also reviewed certain
human-performance technologies designed to enhance human
abilities beyond normal levels, which are also the concern of the
Panel on Mind-Body Interventions (Druckman and Swets, 1988).
Because the conclusions of the NRC reports differ from our own,
and because these reports have been influential in shaping public
opinion about the effectiveness and benefits of certain mind-body
interventions, we believe it is important to comment on these
discrepancies.
We shall focus on the NRC's treatment of
meditation, one of the approaches we have closely examined, and
parapsychology, an indirectly related area, to illustrate these
differences of opinion and describe how they have taken shape.
Meditation
The 1991 NRC report stated, "Overall, our
assessment of the scientific research on meditation (primarily,
transcendental meditation [TM]) leads to the conclusion that it
seems to be no more effective in lowering metabolism than are
established relaxation techniques; it is unwarranted to attribute
any special effects to meditation alone" (Druckman and
Bjork, 1991). The NRC report reached this conclusion by drawing
primarily on two previous narrative reviews. One of these, by
Holmes, covered less than half the relevant studies on TM
available at the time it was prepared (Holmes, 1984). The other,
by Brener and Connally (1986), also appears to have ignored much
of the available and relevant research.
A meta-analysis by TM researchers Dillbeck and
Orme-Johnson on the effects of meditation, published in American
Psychologist, came to a different conclusion but was ignored in
the NRC report. Their quantitative approach showed that the
effect size for TM was more than twice that of resting quietly on
basal skin resistance, respiration rate, and plasma lactate
(Dillbeck and Orme-Johnson, 1987).
Furthermore, Eppley, Abrams, and Shear,
addressing psychological and physiological measures of anxiety,
showed that TM typically produces two to three times the
reductions in effects of chronic stress compared with other
meditation and relaxation techniques (Eppley et al., 1989). Yet
the NRC report said "no evidence supports the notion that .
. . meditation permits a person to better cope with a
stressor."
Meta-analysis allows quantitative analysis of
various aspects of the literature. For instance, it allows one to
compare the results of studies done by experimenters who are
cordial, neutral, and negative toward TM. The Eppley
meta-analysis demonstrated that the distribution of effects was
normal, indicating that the positive conclusions reached in
studies of TM are not the result of selective reporting, and that
the NRC's characterization of researchers who are practitioners
of meditation as subjectively biased "devotees" is
without merit. The Eppley meta-analysis also contradicted the
Brener and Connally claim that meditation research suffered from
"weak design" by providing quantitative demonstration
that the results cannot be accounted for by subject selection,
experimenter bias, expectancies, or atmospheric effects.
The NRC report embodies some faulty assumptions
about meditation. It expresses the expectation that meditation
should "[lower] reactivity to challenge"--that is, to
make one less responsive to stressors, perhaps through
"distracting a person" or providing a "quiet
place." But this is neither the traditional nor the express
purpose of TM, which is to achieve "restful alertness, a
state of unifying capacity." These misunderstandings may be
due to the fact, acknowledged by the NRC, that no one on their
committee was personally familiar with the experience of any of
the meditation practices they reviewed. The difficulties this
created were also acknowledged by the committee: "It seems
appropriate to be mindful of the constraints that science, as
well as culture, background, and personal life experience, place
on how the committee views the field of meditation."
The most glaring omission in the NRC report is
a large database (more than 40 published reports) of societal
impact studies on what the TM researchers call the consciousness
field. The theory underlying this research is that the field,
when supported by a sufficient number of meditators, produces the
effects and benefits of meditation in the larger population. This
is a nonlocal effect, a type of action-at-a-distance, and the TM
researchers describe a correspondence to aspects of quantum
nonlocality in their efforts to explain the results of these
studies.
On the positive side, the NRC report makes a
number of very sensible recommendations for research. In a
general observation, they state that "learning to relax and
enjoy good feelings may prompt a person to make positive changes
in his or her work and personal situation. . . . [I]t may be that
meditation and relaxation . . . effect cognitive change."_
Their overall conclusion restates a question about relative
efficacy and constitutes an implicit recommendation for more
incisive research, but they do not dispute the potential
therapeutic effects of meditation broadly defined.
Parapsychology
In its 1988 report the NRC is strongly critical
of parapsychology, a field that studies, from an independent
perspective, the nonlocal events exemplified in prayer and
mental-spiritual healing that we have reviewed earlier. The NRC
emphasized their belief that more than 130 years of research have
failed to find any evidence of parapsychological phenomena.
Because of the relevance of this research to issues addressed by
the Panel on Mind-Body Interventions, the literature was
examined, revealing impressive evidence in clear disagreement
with the NRC's conclusion.
In the December 1989 issue of Foundations of
Physics, Radin and Nelson reported the largest meta-analysis of
parapsychological findings ever done--a total of 832 studies from
68 investigators, involving the influence of human consciousness
on microelectronic systems (Radin and Nelson, 1989). The results:
"Radin and Nelson's meta-analysis demonstrates that the . .
. results are robust and repeatable. Unless critics want to
allege wholesale collusion among more than 60 experimenters or
suggest a methodological artifact common to . . . hundred[s of]
experiments conducted over nearly three decades, there is no
escaping the conclusion that [these] effects are indeed
possible" (Broughton, 1991; Jahn and Dunne, 1987).
Meta-analysis has also been applied to research
studies in precognition, which typically involve card-guessing by
a subject before the targets are even prepared. Honorton and
Ferrari found 309 studies in English-language publications by 62
investigators, involving more than 50,000 subjects who
participated in nearly 2 million trials. Their findings were as
follows:
* Thirty percent of the studies produced
statistically significant results (where 5 percent was expected
by chance). The odds of this result happening by chance are
approximately 1 in 1,024.
* The results could not be explained by the
failure of researchers to report negative studies (the "file
drawer" effect).
* Studies with the most rigorous methodology
tended to produce better results (exactly the opposite of
critics' claims).
* The effect size remained constant over the
more than 50 years under consideration (Honorton and Ferrari,
1989).
An excellent summary of the techniques of
meta-analysis applied to several parapsychological databases was
published in 1991 by Jessica Utts in Statistical Science (Utts,
1991).
A charge frequently made about parapsychology
and the nonlocal therapies we have examined is that the quality
of research in these areas is low or substandard. In its 1988
report, the NRC commissioned psychologist Robert Rosenthal of
Harvard University to prepare an evaluation of all the
controversial areas of interest to the NRC committee.
Parapsychology researcher Richard S. Broughton describes this
undertaking:
Rosenthal is widely regarded as one of the
world's experts in evaluating controversial research claims in
the social sciences and has spent much of his career developing
techniques to provide objective assessments of conflicting data.
Neither Rosenthal nor his coauthor, Monica Harris, had taken any
public position on parapsychology. . . . The report by Harris and
Rosenthal determined that the "research quality" of the
parapsychology research was the best of all the areas under
scrutiny. . . . Incredibly . . . [the] committee chairman . . .
asked Rosenthal to withdraw the parapsychology section of his
report. Rosenthal refused. In the final document, the Harris and
Rosenthal report is cited only in the several sections dealing
with nonparapsychological topics; there is no mention of it in
the parapsychology section (Broughton, 1991).
The Panel on Mind-Body Interventions believes
it is necessary to acknowledge and document our differences of
opinion with the NRC reports. At the same time, we do not wish to
overemphasize or dwell on these conflicting points of view.
If the field of alternative medicine is to
progress, it is vital that any evaluation of mind-body practices
be comprehensive, rigorous, and unbiased.

Appendix F: A Guide for the Alternative Researcher
by Claire Cassidy, Ph.D., Barrie Cassileth,
Ph.D., Wayne B. Jonas, M.D.,
Richard Pavek, and Linda Silversmith, Ph.D.
The guidelines in this appendix are provided to
assist the alternative researcher. The topics presented were
selected from a broader array of methodologies and approaches.
There is no intention to be all-inclusive. Topics that were
omitted may nevertheless be appropriate tools for conducting
alternative research.
General Methodological Guidelines
Research studies on alternative medical
therapies should be held to the same rigorous scientific and
ethical standards that are applied to research on conventional
therapies. The guidelines in this appendix represent a summary of
major principles for new investigators as they begin to develop
research protocols or grant applications. It is recommended that
at least one investigator in each study of alternative medicine
be experienced in the therapy or research area to be
investigated.
It takes as many years to learn how to conduct
good research as to become an accomplished practitioner of
alternative medicine. Alternative practitioners who wish to do
research need to increase their understanding of good research
design, but they should also seek out experienced researchers to
guide them as collaborators or resources.
Approaches for conducting research must follow
a logical sequence for gathering useful data. Typically, research
on a given topic is first exploratory, then descriptive and
qualitative, then correlative and comparative, and finally
experimental and quantitative. Interviews and surveys are
examples of descriptive research or possibly
correlative/comparative research; best case series fit the
correlative/comparative category; and clinical trials are
experimental.
Once a decision has been made that a topic is
worthy of investigation and not duplicative of previous work,
preliminary or pilot studies (exploratory-descriptive) generally
are carried out to determine whether there are any promising
effects worthy of further investigation and to detect any
negative side effects or practical difficulties. These studies
may consist of anecdotal case reports, systematic case studies,
or uncontrolled single-group studies. Questions are then
formulated for use in controlled comparisons
(correlative-comparative) using controls such as the best
available "other techniques" or a placebo. A large
enough group of patients and sufficient time are necessary to
provide enough data to suggest whether the treatment is really
working and what conditions seem most practical. If effectiveness
is reported, then large studies (experimental-quantitative), such
as clinical trials, should be organized to find out whether the
earlier observations hold true with a more detailed examination
using a greater number of participants.
Whatever the research approach, the following
procedure generally applies:
Identify the paradigm, model, or pattern and
explanatory strategies that underlie the intervention under
consideration for testing and evaluation.
Carefully develop one or two precise
research questions to form the basis of the study. The research
questions are crucial because they lead directly to the study's
objectives, methods, implications, and so on.
Ensure that all components of the research
plan relate logically to one another. Research questions, goals,
subject groups, therapies (regimens, products, etc.) to be
studied, and methodologies must be mutually consistent and
appropriate. When conceptualizing study objectives, make them
consistent with research questions and assumptions of the
intervention; in turn, make the study design (the strategy for
conducting the study) consistent with research objectives. For
all procedures that are operator dependent, identify the skills
training and experience of the operator (e.g., teacher or
deliverer of treatment). Clarify the nature of the population to
be studied; in particular, identify whether the entry criteria
lead the study population to be different from the spectrum of
people being treated by practicing clinicians.
Conduct a library search and gather a
comprehensive collection of previous research in the specific
area to be studied. Because of incomplete archiving and indexing,
computer database searches are currently inadequate to capture
the information needed. It may be necessary to read published
articles in their entirety and to speak with representatives of
alternative medical organizations to locate some references and
information. Literature reviews should be comprehensive and
systematic (see the "Guidelines for Conducting Literature
Reviews" section below).
Explain explicitly the methods used to
obtain the literature. Simple citation of publications is not
adequate. Literature obtained through library search serves as
the basis for the "Background" section of grant
applications or manuscripts. Background sections should
incorporate accurate, high-quality summary evaluations of
existing literature. If a systematic review (see the
"Introduction to Systematic Reviews" section) or
meta-analysis (see the "Introduction to Systematic
Reviews" section) has been conducted to quantitatively
evaluate the literature, this point should be noted.
Clearly define (not just label) the
intervention to be tested or evaluated.
Include in the study any special diagnostic
or outcome aspects of the alternative medicine practice that can
be reliably measured.
Thoroughly and objectively document all
procedures and events that occur during the research study, from
subject accrual through data collection, data analysis, and
reporting of results.
In clinical research (studies involving
humans), include adequate control groups and provide followup of
subjects over time, with appropriate monitoring of both the
intervention group and the control group.
In clinical research, consider and minimize
any potential risks to subjects. Along with other required
information, these risks must be explained to potential subjects
in an informed consent document, provided by the sponsoring
institution's human subjects committee or institutional review
board.
Before research begins, decide and indicate
in the research proposal what will be considered sufficient
evidence to recommend inclusion of the intervention in clinical
practice (if relevant).
Where appropriate, use standard comparative
outcome measures that will allow the new data to be compared with
previous and future information on the same topic.
Obtain expert guidance on computerizing and
analyzing research data. Biostatistics and computer programming
assistance will ensure proper management and analysis of data.
Guidelines for Conducting Literature Reviews
Summary information about previous work in a
given field is necessary for grant applications and publications.
In addition, literature reviews in and of themselves often are
useful additions to the literature.
Overview of Goals of the Review
The literature review must address a clearly
focused question. It should specify the particular population,
intervention or treatment, subject or diagnostic group, or the
like, on which the review will focus. A summary table of all
studies included in the review, along with their data, may be
appropriate. The review should address a specific and pragmatic
issue.
Literature Search
The process of collecting relevant articles
must be comprehensive and thorough. The search should use
bibliographic databases such as MEDLINE, Science Citation Index,
Social Science Citation Index, references from relevant articles,
personal communications with authors, and manual searches of
databases such as Index Medicus. Note that currently this
approach may locate only 25 to 50 percent of articles on
alternative medicine because most such articles do not appear in
standard medical journals (see the "Research Databases"
chapter).
Search methods must be systematic and clearly
described. Possible selection bias must be addressed when
articles are obtained through personal contact. Negative studies
should be described along with others; their exclusion suggests
possible bias.
Selection of Articles for the Study
The chosen method for selecting articles must
be clear, systematic, and appropriate. Inclusion and exclusion
criteria should be preestablished in the form of a protocol to be
followed when reviewing articles for inclusion; the selection
process should then be followed systematically.
The selection protocol should address major
criteria that are relevant to the therapy or system under review,
including whether the population is adequately defined, whether
the exposure or intervention is clearly described, and whether
outcomes are detailed and comparable.
Articles should be reviewed in random order and
selected as they meet the preestablished criteria. The
reliability of the selection process can be measured by comparing
articles collected by at least two independent selectors (expert
and nonexpert). The extent of selection disagreement can then be
evaluated, and a method can be developed to deal with discordant
selections.
Research Quality
The quality of the methodology of each study
under review is evaluated according to a single set of standards
applied to all studies, whether or not the studies have been
published. Literature evaluation must be reproducible. It should
be conducted by evaluators who are blind with respect to authors,
institutions, and study results. These methods of assessment
should be described in the introduction to the literature review.
Combining of Results
Results across studies may be combined only
when the studies are adequately similar. Study designs,
populations, exposures, outcomes, and direction of effect should
be similar enough to warrant combining. If studies are
methodologically similar, it is less likely that chance
influences their results. Analysis of numerous subgroups matched
between studies should be avoided, as spurious statistical
significance is likely to result. Comparisons are more likely to
be valid if variation in the primary studies is considered when
results are combined. Differences in study design and components
(e.g., population, exposure or intervention, outcomes) should be
addressed. Any nonstatistical criteria used for comparison should
be explained.
Meta-Analysis and Systematic Reviews
A statistical review method that combines data
from several studies is termed meta-analysis (or statistical
meta-analysis). These quantitative analyses, which require
similar study samples, interventions, and outcomes, can evaluate
the magnitude of treatment effect (percentage risk reduction) and
the possibility that the differences were due to chance.
Meta-analyses can be used to determine the frequency (i.e.,
quantity) and the quality of the research method employed in
studying a specific factor or issue within a single research
field or across several fields of study.
Systematic reviews are another orderly approach
to reviewing research literature. Like meta-analysis and other
quantitative review methods, systematic reviews use clearly
specified methods to avoid the introduction of bias in the
selection and interpretation of the research literature being
reviewed. Clearly defined criteria for including or excluding
specific journals and articles are applied; additional criteria
are used to evaluate the quality of the measures applied in the
reported research to assess the topic of interest. Systematic
reviews differ from meta-analyses in that the studies selected
for review need not use strictly similar study samples,
interventions, or outcome measures.
For additional information, see the
"Introduction to Meta-Analysis" and "Introduction
to Systematic Reviews" sections.
Significance of Results
The importance of the results can be determined
by calculating an odds ratio (the odds of the effect occurring in
the exposure group divided by the odds of the effect occurring in
the control or comparison group). The resultant number should be
large to have any significance. The results should be reported in
a clinically meaningful manner such as the absolute difference or
the number needed to treat. The results also should be
reproducible and generalizable, with similar effects on different
types of subject groups. (The level of significance of results
could become a criterion for including studies in an alternative
medicine research database; such a database is proposed in the
"Research Databases" chapter.)
All clinically important consequences should be
considered, including other outcomes from the intervention or
treatment; these results should be discussed in the context of
those analyzed in the review.
Guidelines for Descriptive and Cross-Cultural
Studies Using Qualitative Research Methods
Overview
Many alternative medical systems and practices
derive from other cultures or reflect models of health and
dysfunction that differ substantively from those current in
conventional medicine. As a result, research on alternative
medical systems often is in effect, if not explicitly,
cross-cultural. The fundamental issue of cross-cultural research
is that people who have different views of what constitutes
reality also experience reality differently. This means that
questions, concepts, diseases, treatments, and research protocols
that "make sense" in one setting may not make sense in
another.
Before conventional quantitative techniques can
be validly applied to the scientific analysis of alternative
medical systems, enough must be known of these systems to
understand how their beliefs (conscious and unconscious) and
behaviors differ from those of conventional systems. These
differences can then be taken into account in research design.
Failure to know about and account for differences leads to
uninterpretable or inaccurate research, raises the potential for
misapplying findings to the care of patients, and violates the
criterion of model fit.
Methods for cross-cultural research--adjusting
for the existence of different models of reality--are most highly
developed in the social sciences, especially anthropology and
communications, and have been incorporated into medical outcome
studies. These methods are mostly categorized as qualitative, but
quantitative versions of some techniques are available. In
practice, most cross-cultural descriptive research demands the
use of qualitative methodologies or a mixture of qualitative and
quantitative techniques.
The focus of qualitative research is the
individual practitioner or patient, and the community. This form
of research is respondent centered, and researchers must take
care not to impose their own assumptions or biases on data
collection. Qualitative research requires the use of open-ended
research techniques or instruments. The research team should
include investigators who have had prior experience with
qualitative methods and have produced publications that provide
evidence of relevant expertise.
Methodological issues of clarity, validity, and
the testing of hypotheses are similar in qualitative and
quantitative research (see the "Guidelines for Clinical
Trials" section for a summary). Correspondingly, in
qualitative research as in quantitative research, concepts are
detailed, theory is constructed by the testing of hypotheses,
data are collected systematically, and criteria of soundness are
applied to design, data collection, and interpretation.
Uses of Qualitative Research
Qualitative research is a body of techniques
and assumptions concerning how to gather and analyze complex
real-world data so that they can be applied to real-world
problems (Bernard, 1993; Denzin and Lincoln, 1994; Marshall and
Rossman, 1989). All qualitative research shares a set of
assumptions or concepts about the research field (Marshall and
Rossman, 1989):
To find out about people's behavior, it is
best to immerse oneself in the actual setting chosen for study.
The participants in the study have values
that researchers must honor.
The researcher's task is to discover these
values and perspectives and how they affect the participants'
behavior and experience.
Research is an interactive process.
Research relies on people's words, stories,
and actions as the primary data.
Accordingly, in qualitative or field research,
the investigator has direct contact with research subjects and is
directly and personally involved in data collection and analysis,
with the aim of generating realistic descriptions and
explanations. The choice of data collection methods, sampling
procedures, and analytic approaches during the research process
evolves into a question-specific research design (Crabtree and
Miller, 1992). As data are collected and analyzed, this iterative
process affects future decisions for additional sampling,
collection, and analysis.
Data collection in field research is
accomplished primarily through the use of observation,
interviewing, and recordings. The researcher may be required to
make relatively "unstructured" observations or
"structured" observations that depend on a particular
knowledge base. Observation is formalized in many ways, including
studying proxemics (how people use space) and kinesics (how
people move to communicate), participant observation, and various
unobtrusive observational measures in which participants are
unaware that they are being observed.
The basic approach for data collection usually
consists of interviews with individuals or groups. Focus-group
interviews are appropriate in some settings and for some purposes
but should not replace individual indepth interviews (McCracken,
1988). Sometimes questionnaires can be administered as
interviews. Interviews may be conducted at several
levels--unstructured (guided everyday conversation),
semistructured (more focused but still open-ended), or structured
(like spoken questionnaires). Conversations and events may be
recorded with audio or video equipment.
Surveys can be constructed on the basis of
interview data and, though not administered in a face-to-face
setting, can be personalized by offering respondents
opportunities to expand on their answers or to contact the
researcher for an interview if they want to say more than the
survey form permits.
Qualitative researchers have also developed
various projective instruments that elicit respondents'
unconscious knowledge and beliefs. For example, anthropologists
use card-sort and triad-sort techniques, geographers use
"mental map" techniques, and psychologists use various
picture-response instruments. Preexisting instruments are rarely
appropriate for studies across cultures or medical systems.
Much qualitative research also uses secondary
sources, such as films, videotapes, texts, and photos.
Historical, proxemic, and content analyses of these materials can
reveal the unstated values and assumptions of the producers and
participants.
To analyze the data collected, the researcher
must develop an organizing system, segment the data accordingly,
and then determine connections. If the data do not sort well into
the categories first selected, the organizing system must be
revised. Connections among the sorted data may be made either
statistically or interpretively.
Analytical goal
The goal of any analysis is to bring order to
what are often extremely complex data. Qualitative researchers
try to discover classes of behavior or responses, themes that
guide interpretation of events, and differing patterns of
response. The first step is descriptive--simply to disentangle
the data. Researchers then try to generalize, that is, to find
and name the rules under which a particular result may be
expected and to explain why this should be so. Much qualitative
research eventually is applied in efforts to improve the quality
of life, for example, by delivering health care in ways that make
sense to the target population.
To be considered useful, qualitative research
must fulfill certain criteria of soundness. It must be clear
under which circumstances a particular finding applies and
whether a finding works consistently. Another demand is that this
research be objective. Traditional criteria, such as reliability
and validity (see the "Guidelines for Clinical Trials"
section), are applied (Kirk and Miller, 1986). However, some
authors have defined different criteria of soundness for
qualitative research (Lincoln and Guba, 1985; Marshall and
Rossman, 1989):
Credibility. The conduct of inquiry must
enable the subjects of the research to say, "Yes, that
question (or that interpretation) sounds right to me." This
demand can be met because qualitative research deals directly
with research subjects.
Transferability. A researcher samples a
population and makes generalizations about the whole population.
If another researcher thinks this generalization applies to a
different population, tests it, and finds it to be true, then the
criterion of transferability has been met. Note that the
underlying concepts are transferred, not the specific data.
Dependability. Rather than assume that
observed events can be replicated (the reliability assumption in
quantitative research), qualitative researchers want to be able
to account for events as they arise and change. When they do so
successfully, the criterion of dependability has been met.
Confirmability. This criterion is met when
the findings of one researcher can be confirmed by another.
Qualitative researchers can easily bias their data collection by
becoming subjectively involved with the research field; this
criterion helps to ensure that excessive subjectivity is not
biasing the data, that is, that the data are objective.
Although analytical procedures in qualitative
research are not necessarily statistical (as they are in
quantitative research), some distinct statistical methods can be
applied to qualitative research (Bernard, 1993; Miles and
Huberman, 1994); software programs such as Anthropac, Ethnograph,
and NUDIST, are available to apply these analyses.
Qualitative Versus Quantitative Methods
Research design often requires a combination of
qualitative and quantitative approaches. Qualitative and
quantitative research differ in the underlying assumptions that
researchers make (Cassidy, 1994). In quantitative research,
scientists are likely to detail (and often count) particularities
and therefore focus on strategies that limit the view, even if
they must do so artificially. The randomly assigned, blinded,
controlled clinical trial is an important example of this
approach; it is not like the real world, because patients
normally do not choose practitioners or treatments randomly, and
both practitioner and patient usually know what is going on.
Quantitative methods are useful for answering
the following types of questions: How many? How much? How often?
What size? What are the measurable associations? What will happen
if . . .? Does one variable cause the other? Is A more effective
than B? The quantitative approach serves to isolate variables so
that their influence on outcome can be separated from other
factors that might otherwise cloud the interpretation.
In contrast, qualitative researchers are
interested in complexity and pattern--the interactions among
variables--and purposely avoid approaches (such as the use of
controls) that simplify and focus. Qualitative methods are useful
for answering the following types of questions: What is going on?
What is the nature of the phenomenon? What variations occur? How
does it work? How did something happen? What patterns can be
identified? Is the original theory or hypothesis correct? Does
the original theory fit other circumstances? What difference does
this program or intervention make? Why does this intervention
work or not work?
In a real-world medical setting, these
questions might address the following issues:
* Differences in therapeutic effectiveness when
patients are assigned or freely choose their health care.
* How patient and practitioner interact, and
how this interaction affects the medical outcome.
* How the design of the health care delivery
setting affects patient or practitioner satisfaction.
* How patients compare care in two different
medical systems.
* How patients become acclimated in a new
(e.g., alternative) system of medical care.
There is another important difference between
qualitative and quantitative approaches. Quantitative research
depends on an assumption that a certain commonality or
unchangingness underlies how materials interact. This assumption
translates to a demand that a hypothesis be tested the "same
way" and "as planned" in different research
settings. Once the research has begun, the protocol cannot be
changed, for doing so introduces new variables that would
invalidate the work.
Qualitative research depends on the opposite
assumption, namely that the real world always involves flux and
change. Qualitative research protocols outline the goal and
approaches, but they are based on the assumption--indeed, the
expectation--that unpredictable events will occur and that the
research protocol can be changed as one means of dealing with
these events (Marshall and Rossman, 1989). Such changes do not
invalidate the qualitative research so long as researchers
recognize that change is necessary, document the reasons, and
create a logical means to deal with the novel event.
Qualitative methods can explain the real world
of alternative health care delivery. The qualitative approach is
an ideal way to elucidate outcomes issues (as in cost and
clinical effectiveness studies) and can be used in settings where
little is known about a practice and its theory, techniques,
practitioners, or users. When qualitative and quantitative
methods are linked, researchers are able to gather fruitful data
suitable for use in improving the delivery of health care.
Guidelines for Screening Best Cases
Introduction
Many practitioners of unconventional therapies
for cancer and other illnesses have not documented the effects of
their treatments, yet they claim positive results. A process is
needed to screen such claims to determine whether each patient,
or case, provides enough information to qualify as part of a best
case series and then to determine whether there are enough cases
to meet criteria for a best case series.
The guidelines summarized below were adapted
from a National Cancer Institute publication (NCI, 1991) produced
to assist the development and reporting of best case series for
unconventional cancer treatments. These guidelines retain
references to cancer therapies, but a similar approach could also
be applied to some other unconventional treatments. Applying this
simple and reliable best case evaluation system should enable
many unconventional therapies to be screened for adequate
information. If available information were not found to be
adequate, further attempts to evaluate the therapy would be
postponed until better information could be obtained._
With sufficient information to create a best
case series, cases that meet NCI's criteria (or other designated
criteria for other health problems) can be determined. Necessary
information includes documentation--using standard measures--of
the patient's diagnosis, staging (severity of illness),
treatment, outcome, and so on. The procedure for determining
adequate best case information includes six steps.
Conclusion
NCI's best case criteria represent a specific
and reliable means of uncovering therapies worthy of study. This
approach uses a single standard to detail the amount of
information available and the response achieved.
This method is used to screen charts for
adequate information, estimate clinical response, and evaluate
practitioner judgment about clinical response. It provides a
systematic method for determining which one or ones of the
numerous unconventional approaches to cancer warrant further
evaluation through clinical trials. The method is applicable to
therapies for other problems besides cancer when appropriate
evaluators are available.
Guidelines for Clinical Trials
The following guidelines address major
methodological issues relevant to designing and conducting
clinical trials. The final guideline addresses how interactions
between the subject and the health care practitioner may affect
study results.
Model Fit
The basic assumptions about health and disease
intrinsic to the system under study should be noted, as should
the model for classifying and treating patients by that system.
For example, if clinical acupuncture care is under investigation,
a description of qi and meridians (see the glossary) and the
criteria for patient classification and outcome changes must be
presented.
The study population should be selected and
classified in a way that reflects the assumptions of the model
under consideration. For example, if the study addresses disease
outcomes, proper diagnostic categories must be used. If the study
involves assumed changes in energy patterns, pulses, or symptoms,
patients must be classified according to these criteria from the
outset. Outcome measures used must be consistent with these
assumptions.
The design and methods to explore the
intervention must be selected in a way that is consistent with
the model's assumptions and with the objectives of the study.
Methodologic goals include efforts to (1) demonstrate any effect,
(2) assess relative effects between therapies or therapeutic
systems, (3) test the utility of an intervention in actual
practice, (4) evaluate a possible mechanism of action, (5)
examine an assumption that underlies a practice, (6) examine
patient reports of satisfaction and relevant explanatory models,
(7) examine practitioner explanations of what happened and why,
and (8) examine the character of the practitioner-patient
relationship and how it affects the delivery and receipt of care.
The goals of the investigation in relation to
the system under study must be clearly delineated in the
protocol. The study's title and conclusions should reflect the
assumptions of the relevant model and the study goals that were
actually investigated.
Hypothesis
Clearly established hypotheses should be
contained in the research description or grant application. These
should identify or predict the main results so that analyses can
test the hypotheses.
Patient Selection Bias
The means by which people are identified and
accrued to the study, as well as the numbers of potential
subjects who decline participation, must be carefully recorded.
For example, did subjects come to the study through
advertisements? Were they recruited from clinical practices? By
random dialing?
Eligibility and selection (inclusion/exclusion)
criteria should be clearly stated. Criteria used to diagnose or
classify subjects must be valid and reliable. A reference should
be given to document the established reliability of the
classification system used. In cancer studies, for example,
detailed and specific classifications are established (see the
"Guidelines for Screening Best Cases" section).
If no generally accepted classification system
exists, the system used in the study must itself be detailed and
defended in the methods of the current trial.
Randomization or Matching
Comparison groups are developed through a
specific process such as randomization, matching, or
stratification. Randomization (or a related procedure) applied to
a large enough group should distribute differences in the control
and treatment groups in a random fashion. In this way the two
groups are "equalized" and made as similar as possible
except for the intervention to be studied. The method used to
create the comparison group should be clearly described. The
method should be balanced at least by age, gender, specific
diagnosis and stage of disease, important prognostic factors, and
other factors relevant to the particular study.
Control Subjects
To obtain comparative data that will shed light
on results found in the treatment (or experimental) group of
subjects under study, an appropriate control group is needed.
Data from control and treatment group subjects are gathered
simultaneously by the researchers. Ideally, the groups are
identical except for the treatment or intervention to be studied.
However, because no two people are identical in every way that
may relate to the illness or therapy to be studied, subjects are
randomized or matched.
Blinding
Evaluators of the condition of subjects should
be blind with respect to (1) whether subjects receive the
intervention or a placebo treatment, (2) how the outcome will be
measured, and (3) how results will be analyzed.
Crossover Bias
There should be no dilution or co-intervention,
that is, the treatment group should not receive any other therapy
or intervention in addition to that evaluated in the study. There
should be no contamination, that is, control subjects must not
receive the same treatment or one that is similar to the
treatment received by the experimental subjects.
Confounding Factors
Possible confounding variables (factors that
may influence the study's results) must be addressed adequately.
The study groups should be comparable on important prognostic
factors. All funding sources should be disclosed, and reports
should indicate whether these sources were independent of
potential profit from the type of treatment under study.
Sample Size
Estimates of the required number of subjects
must be made before the study begins and must be discussed in the
research proposal. The statistical basis for selecting the number
should be given, and the calculations that led to that number
should be described. The research proposal also should provide
information about how the researchers plan to attain the desired
sample size.
Outcomes and Measurement Errors
Outcome and measurement criteria must be
clearly defined and explicit. The validity of the outcome
measurements used should be established by references and by
verification within the study (against a "gold
standard" or parallel outcome measures). The measurement
methods used must be sensitive enough to detect the outcome or
change to be investigated. All important outcomes must be
reported.
The duration of effects must be considered in
evaluating outcomes. For example, if subjects of a treatment are
crossed over to a control group, consideration must be given to
whether they were still experiencing effects from their treatment
after the crossover. Statistical mechanisms for handling this
type of problem exist.
Loss to Followup
At least 80 percent of subjects brought into
the study should be shown to remain with the study long enough
for necessary followup to occur. Subjects who withdraw from the
study must be fully described. For the study results to be
acceptable, subject characteristics (including age, gender,
diagnosis, stage of disease, and other important factors) must be
similar for those who withdrew and those who remain in the study.
Statistical Methods
Descriptive statistics (data) are presented on
all prognostic and outcome factors. Inferential and
hypothesis-testing statistics (p-values) are calculated and
reported for all major treatment-outcome links. Confidence
intervals or probability distributions also are reported for
primary treatment-outcome links.
Multiple Measures
When more than one measure, variable, or
comparison group is assessed, appropriate analyses are applied.
Examples of such analyses include analysis of variance with
multiple comparison groups, post hoc analyses, subgroup analyses,
multiple hypothesis testing with serial t-or z-tests, and serial
dependent measures.
Clinical Significance
Clinical (versus statistical) significance
indicates whether research effects are important or meaningful.
Patient or physician satisfaction with treatment is an example.
Results that achieve statistical significance are not meaningful
unless they are also clinically important or meaningful in
clinical practice. For example, a very small difference in the
effectiveness of two treatments would not be likely to change
clinical practice or to influence physicians or patients to adopt
the new treatment.
The new treatment should have a low risk of
causing direct harm in comparison to the risks of not treating
the disease. If risks associated with the treatment are low, the
treatment is more likely to be used.
Generalizability
Results cannot be generalized beyond the type
of illness or patient studied. Any other studies that addressed
the same research questions should be discussed in the protocol.
If intervention X is shown to work for patients with diabetes,
for example, it cannot also be said to work for people with other
illnesses. If intervention Y produces good results in breast
cancer, it cannot be claimed to work in lung cancer. Broader
generalizability is possible only with very large research
projects that include adequate numbers of men and women of
different age groups, disease severity categories, and stages of
the illness.
As a general guideline, there should be at
least 40 people in each group for each treatment-outcome link
examined.
Disclosure Issues
The sources of funding for the research should
be disclosed, as should any additional sources of funding for the
participating investigators when these sources have the potential
to influence their work. Reports on the research should indicate
whether any of these sources might potentially profit from the
type of treatment under study or might profit from an alternative
treatment if the treatment under study were discredited.
Patient and Practitioner Beliefs and
Interactions
Often in clinical trials, the beliefs of and
interactions between investigators and subjects are assumed not
to be important, but in alternative medicine these are valid
concerns. This guideline addresses such personal considerations.
One consideration is bias, which is not usually
intentional in research. The differences that could introduce
interference or bias in the conduct of the research should be
identified and evaluated. Among these are (1) whether the
treatment is delivered in the usual method and style used in
health care practice, (2) whether the health care practitioner
and patient have expectations about the treatment results, (3)
whether the patient has complied with the treatment regimen, and
(4) whether interference with normal spontaneity and flexibility
in patient-therapist interactions has been avoided or noted.
Utility of the treatment involves the question
of whether the treatment, as reported, could be applied by
practitioners other than those who participated. The
investigators' belief in the efficacy of the treatment should
also be assessed, and any idiosyncratic responses or beliefs
should be described.
Study subjects must be adequately prepared for
their participation. The view of each subject on the need for
treatment should be evaluated. For example, does the subject
regard the problem as a major or minor condition?
The possibility of transpersonal phenomena
should also be considered. Such phenomena might include cultural
or spiritual perceptions of the study's importance; cultural
disparities in treatment delivery; events that might affect
outcome, such as direct observer and evaluation effects_; and
possible field--that is, nonlocal--effects.
Introduction to Outcomes Research
Outcomes research evaluates the ultimate
effects of treatment systems on patients. This evaluation usually
involves a retrospective examination of records or databases
accumulated by health care practitioners, hospitals, insurers,
and government health programs in order to identify which medical
interventions produced the best outcomes (Wennberg, 1990). It is
also possible to conduct prospective research by tracking
clinical practices concurrently into the future. Outcomes
research has been described as the use of natural experiments to
find what works in medicine.
The databases under examination in outcomes
research may be developed by using various kinds of research
methods--descriptive (qualitative), best case (mixed qualitative
and quantitative), or quantitative. Clinical case records and
insurance claims data are often perused.
Advocates of outcomes research claim that it is
potentially cheaper and faster than clinical trials and can
provide data on treatments that would not otherwise be evaluated.
In fact, retrospective database analysis may be the only way to
obtain data on treatments with rare complications. Outcomes
research is also useful when dealing with "soft"
results such as effects on the quality of life. Consequently,
some advocates of alternative medical practices consider outcomes
research ideal for examining aspects of alternative medicine.
Outcomes research has other inherent
advantages. It does not interfere with the doctor-patient
relationship, does not require informed consent or permission
from an institutional review board (as do clinical trials), and
includes groups (such as the elderly, children, the poor, and
minorities) that might not be widely represented in clinical
trials.
Critics point out that any research based on
retrospective analysis of clinical records is flawed by hidden
biases in the data. They claim that researchers cannot correct
for the subtle reasons why doctors choose one treatment over
another for a given patient (or why patients choose their
doctors). Furthermore, the records under examination were made
for a different purpose and are likely to be incomplete in
describing all relevant conditions that may affect the patients
whose records are being analyzed.
Proponents and opponents of outcomes research
agree that some aspects of the research are useful--that it is
important to learn what doctors are actually doing in clinical
practice and that this knowledge can provide a basis for further
studies, including clinical trials.
One government agency, the Agency for Health
Care Policy and Research (AHCPR), was created in 1989 largely to
conduct outcomes research. However, in a recent article in
Science, Anderson (1994) reported that "after spending
nearly $200 million on outcomes research (about one-third of the
agency's budget . . .), AHCPR cannot point to a single case in
which its database studies have changed general clinical
practice." Anderson further noted that even the agency's
most definitive result--a guideline to physicians that
"watchful waiting" is more appropriate for some
patients than surgery for benign prostate disease (see the
"Research Methodologies" chapter)--was accompanied by a
recommendation for a clinical trial to confirm these findings.
Increasingly, it appears that AHCPR will use
its database analyses of outcomes to supplement and complement
other tools, including case control studies, meta-analyses of
previous studies, and clinical trials. Two new references are
expected to help researchers rank the value of outcomes research:
(1) the proceedings of a March 1993 conference sponsored by the
New York Academy of Sciences that analyzed the relative merits of
outcomes research and clinical trials (Warren and Mosteller,
1994); and (2) the results of an 18-month study by the Office of
Technology Assessment (OTA) analyzing AHCPR's outcomes research
(publication due September 1994)._
Introduction to Meta-Analysis
The term meta-analysis was first coined by G.V.
Glass, in a 1976 study of the efficacy of psychotherapy, as
"the statistical analysis of a large collection of results
from individual literature, for the purpose of integrating the
findings." Although meta-analytic procedures have been
widely employed in the social sciences since the early 1970s,
many did not consider it a valid tool for the natural sciences
until numerous retrospective studies accumulated that used
meta-analysis to analyze data that had previously been studied
with other statistical tools. As these studies illustrated both
the statistical power and the increased information provided by
meta-analysis, interest in its medical applications began to
increase significantly. Since then, meta-analysis has been
applied to questions of efficacy (e.g., chemotherapy in breast
cancer, patient education interventions in clinical medicine,
spinal manipulation); questions of cause and effect (e.g., effect
of exercise on serum lipid level); and, increasingly, public
health problems. Today meta-analysis is being used in a variety
of settings to draw conclusions from results collected from
literature or narrative reviews and from data pooled from
independent studies (often clinical trials).
In general, meta-analysis is a systematic
method that uses statistical analysis for extracting, comparing,
and combining results from independent studies to obtain
quantifiable outcomes. Meta-analysis also can help detect gaps in
knowledge in the published literature and thus can help provide
guidance for future research. Although there have been several
approaches to meta-analysis, each follows the same basic
procedure:
1. Define the problem and criteria for
admission of studies.
2. Locate research studies.
3. Classify and code study characteristics.
4. Measure study characteristics quantitatively
on a common scale.
5. Aggregate findings to study characteristics
(analysis and interpretation).
6. Report the results.
Problem formulation includes explicit
definition of outcomes and potentially confounding variables.
Carefully done, this step enables the investigator to focus on
the relevant measures in the studies under consideration and to
specify the relevant methods for classifying and coding study
characteristics. The literature search uses a systematic approach
to locating studies. First, information is obtained from
colleagues in a particular discipline. Second, the various
indexes, abstracting services, and electronic databases are
searched. Third, references from the primary articles are used to
find secondary sources of information. Finally, information is
gathered from academic, private, and government sources,
including unreferenced reports and unpublished data.
In order to measure results across disparate
studies, several methods are used. The most common method is to
measure the effect size (i.e., an index of both the direction and
the magnitude of the effect of a procedure under study). One
estimate of the effect size for quantitative data is the
difference between the two group means, divided by the control
group standard deviation, (Xt-Xc)/Sc, where Xc is the mean of the
control group and Sc is the standard deviation of the control
group. Effect size expresses differences in standard deviation
units so that, for example, if a study has an effect of 0.2
standard deviation units, the overall effect size is only half
that of another study that has an effect size of 0.4 standard
deviation units. The appropriate measure of effect across the
research literature varies according to both the nature of the
problem being assessed and the availability of published data.
Pooling of data from controlled clinical trials, for example, has
been more widely used in the medical literature than for other
subjects.
Effect size for proportions has been calculated
in cohort literature as either a difference, Pt-Pc, or as a
ratio, Pt/Pc. The latter has the advantage of considerable change
relative to the control percentage; in epidemiological studies,
it is equivalent to the concept of risk ratio.
Whatever combination statistic is used, a
systematic quantitative procedure to accumulate results across
studies should include the following:
1. Summary descriptive statistics across
studies, and the averages of those statistics.
2. Calculation of variance of a statistic
across studies.
3. Correction of the variance by subtracting
sampling error.
4. Correction in the mean and variance for
study artifacts other than sampling, such as measurement error.
5. Comparison of the corrected standard
deviation to the mean to assess the size of the potential
variation across studies.
The value of meta-analysis is that as evidence
begins to accumulate, meta-analysis forces systematic thought
about methods, outcomes, categorizations, populations, and
interventions. In addition, it offers a mechanism for estimating
the magnitude of the effect in terms of a statistically
significant effect size or pooled odds ratio. Furthermore, the
combination of data from several studies increases
generalizability and potentially increases statistical power,
thus enabling more complete assessment of the impact of a
procedure or variable. Quantitative measures across studies also
can give insight into the nature of the relationships among
variables and can provide a mechanism for detecting and exploring
apparent contradictions in research results. Further, because
meta-analysis is less subjective than other analytical methods,
it has the potential to decrease investigator bias.
However, like the value of all review methods,
the value of meta-analysis can be limited by a number of factors.
For example, the current use of parametric statistical methods
for meta-analysis is the subject of intense theoretical study.
Other methodological issues of concern include bias, variability
between studies, and the development of models to measure
variability across studies. One major concern about qualitative
reviews of the literature is that although meta-analysis is more
explicit, it may be no more objective than a narrative review.
Both critics and advocates of meta-analysis are concerned that an
unwarranted sense of scientific validity, rather than true
scientific understanding, may result from quantification. More
simply stated, use of sophisticated statistics will not improve
poor data but could lead analysts to an unwarranted level of
comfort with their conclusions.
Introduction to Systematic Reviews
The systematic review is an orderly approach to
reviewing research literature that minimizes the problems that
can arise with less scientifically rigorous review methods
(Larson et al., 1992). To avoid introducing bias in the selection
and interpretation of the literature under study, systematic
reviews spell out in advance the approach to be taken. Systematic
review entails defining criteria for (1) the selection of
journals and articles to include and exclude, (2) the quality of
the measures used in the selected literature to assess the factor
being reviewed, and, (3) the quality of each study's research
methodology. The technique also looks at the frequency of
assessment of a particular research question, variable, or
measure.
Advantages
Systematic reviews, like meta-analyses and
unlike standard literature reviews, are replicable from one
reviewer to the next. This point is particularly important when a
potentially controversial research topic is being evaluated.
Systematic reviews differ from meta-analytical
reviews in two major ways. First, the systematic review costs
much less--only 10 to 20 percent of the expense of a similarly
sized meta-analysis. Second, systematic reviews can consider
single factors of interest within an inadequately developed
research field. In contrast, meta-analyses require a
well-developed research field with a large amount of experimental
or quasi-experimental research; they also require that an
adequate number of studies address essentially the same research
question using comparable study samples.
While systematic reviews can examine the key or
central findings in studies, they also permit analysis of
noncentral or peripheral factors. Thus systematic reviews are
particularly useful in examining an underdeveloped or
infrequently studied research issue.
Method
There are five key steps in conducting a
systematic review: (1) selecting the factor or factors to be
studied; (2) deciding whether to use an exhaustive review or
field review approach; (3) assessing the frequency and quality of
measurement of the factor of interest; (4) evaluating the studies
that contain the factor of interest; and (5) determining and
maintaining reviewer reliability.
Selecting the factor or factors to be studied.
This first step involves formulating research questions based on
the topic the reviewer wishes to study. Each systematic review
should address clear research questions. For example, several
systematic reviews have focused on whether the quantity or
quality of research containing religious variables was
substandard in certain clinical scientific literatures (Larson et
al., 1986). Another review concerning the effects of pornography
asked whether existing research demonstrated harm--or lack of
harm--in assessing the associations in each literature report
between exposure to pornographic materials and changes in
attitudes concerning rape or aggression toward women.
Deciding whether to use an exhaustive review or
field review approach. Both types of systematic reviews use
research reports that have undergone a peer review process of
critique and revision prior to being published. However, criteria
for what to include and exclude are defined differently for the
two types of reviews.
The exhaustive review method involves
identifying every possible peer-reviewed study from every
relevant field of study that includes information about the
factor of interest. This review is carried out in three steps.
(1) First, an initial list of articles is prepared, based on a
multiple, overlapping, computerized literature search that uses
multiple key-word terms and indexes. (2) Next, other potentially
relevant articles are identified in the reference sections of the
articles obtained in the initial search, and these new articles
are also searched for relevant references. This repeated
reference review continues until no new articles can be
identified for addition to the master list. (3) The final step is
the circulation of the list of articles to identified experts,
such as the three to five researchers with the most publications
on the research study list; these researchers are asked to
identify additional relevant articles.
In contrast, field reviews involve selecting
only one field of study, the leading peer-reviewed journals in
that field, and the period to be reviewed (usually 5 to 10
years). The leading journals are identified as the ones most
frequently cited in a particular research field, by using the
Science Citation Index or the Social Science Citation Index as a
citation source. (These indexes provide ratings of journals in
various research fields based on the frequency with which their
articles are cited). If the goal is to define the most accurate
and up-to-date research in a specific field, then the field
review is the more appropriate type of systematic review to use.
The field reviewer obtains a proper sample by
manually searching through every journal issue and every article
in the journal to identify studies that include the review factor
of interest. Some topics of previous systematic reviews include
mental health factors in nursing home studies, AIDS research in
general medical journals, and religious factors in psychiatry,
family medicine, and pastoral care journals. The total numbers of
articles scanned and articles selected should be tracked.
Editorial articles, commentaries, and other nonquantifiable
opinion articles should be excluded.
Assessing the frequency and quality of
measurement of the factor of interest. In this step the factor of
interest is examined across the reviewed articles to determine
whether it is of major or minor importance--that is, whether it
is frequently or infrequently assessed. Additional information is
tabulated concerning whether the factor is being assessed through
use of one or several questions and--if through several
questions--whether reliability was reported or demonstrated.
Evaluating the studies that contain the factor
of interest. Next the research quality of the studies that
include the factors of interest is assessed. If a study is poorly
designed, its findings may be questionable.
Assessing the quality of the methods used
requires clearly defining each study factor, including such
variables as the response rate, size of the study population, use
of a control or comparison population, type of sampling method
used, and whether study measures demonstrated reliability. For
example, defining the response rate might entail grouping rates
in categories: low, less than 50 percent; medium, 50 to 69
percent; and high, 70 percent and more. Similarly, other factors
require some definition and grouping.
Determining and maintaining reviewer
reliability. Reproducibility of systematic reviews depends on
training multiple reviewers to appropriately assess the factors
of interest. The goal here is statistical reliability, so that
reviewers reviewing the same articles achieve the same
assessments. Training reviewers has been found to produce
replicable results with reliabilities above 0.90 (Larson et al.,
1992).
High reliability can be maintained through
periodic checks--especially if a large number of studies and a
large number of reviewers are involved--and, if necessary,
retraining of reviewers.
Usefulness
The kinds of information that systematic
reviews can provide about a specific research field or topic
include the following:
* Number of studies assessing the factor of
interest.
* Statistical reliability of measures assessing
the factor of interest.
* Approach most often used for assessing the
factor of interest.
* Frequency of assessing the factor as a
variable of major versus minor study relevance.
* Quality of the research studies that include
the factor of interest.

NCIs Suggested Steps for Screening Best Cases
1. Chart Selection
The practitioner or another individual in the
alternative medicine setting reviews clinic charts and selects
those that are believed to represent the best examples of
successful treatment. These charts are copied and brought or sent
to NCI, where an independent evaluator reviews them.
Alternatively, the evaluator may visit the clinic and review the
best case charts on site.
2. Chart Review
The evaluator judges the charts acceptable if
the needed information is present and rejects them if it is
lacking. The reason for either decision is documented. The
evaluator's specific criteria for adequacy of information also
can guide the practitioner to select best cases.
When a specified proportion of submitted charts
contains adequate information, outcome evaluation can be
considered. Charts that provide adequate evidence of response or
lack of response are then evaluated according to outcome
criteria.
3. Inclusion Criteria
Evidence for the diagnosis of cancer (or
another illness under treatment) and details of the treatment
regimen are documented. Clinical information that demonstrates
the status and course of the illness, such as the malignancy and
the sites of metastatic disease, must be detailed. Minimum
evidence includes the following:
a. The diagnosis of cancer must be documented
by one of the following:_*
* A pathology report.
* Radiological, surgical, or blood evaluation,
and a specialist's written report diagnosing cancer or indicating
that it has recurred.
* A specialist's written report that standard
treatment is unlikely to be helpful or has failed, or that the
disease severity prior to alternative medicine treatment
indicated extremely poor prognosis.
b. The patient must have received the
unconventional treatment according to the alternative medicine
practitioner's regimen. Information about the treatment must
include the following:
* Detailed description of treatment source,
doses, method, and delivery frequency.
* Chart documentation of patient compliance,
such as pill counts and completion of at least 70 percent of
followup visits.
* Complete documentation of any other previous
or ongoing therapies, medications, and so on.
4. Exclusion Criteria
The following problems invalidate a chart for
inclusion in a best case analysis. If any of these are present,
the chart information is inadequate:
* No evidence of the disease under study when
the patient began alternative medical treatment.
* No pathology diagnosis or objective evidence
of disease recurrence as defined above when alternative medical
treatment began.
* Inadequate delivery (insufficient dosage or
treatment time) of the therapy under study, or current or recent
delivery of another therapy that could affect the disease.
* Followup less than 6 months from the start of
therapy, or less than 2 standard deviations beyond the patient's
expected survival, as determined by current estimates of life
expectancy for the same diagnosis and stage of the disease when
treatment was started.
5. Outcome Criteria
If criteria for adequate information as
described above are met, cases can be reviewed according to
outcome (clinical response) criteria. If outcome criteria also
are met, it can be concluded that the therapy is producing
positive results and that further study may be warranted. Outcome
criteria consist of complete or partial clinical response as
determined by the following standard oncology definitions:
* Complete tumor remission. Complete
disappearance of all evidence of tumor (all sites of measurable
disease) for a minimum number of weeks.
* Partial tumor response. Fifty percent
decrease in the size of the tumor. This is calculated as the sum
of the perpendicular diameters of all measured lesions, with no
progression of disease at any site and no appearance of new
lesions for a specific number of weeks.
* Prolonged quality-of-life expectancy.
Evidence that the patient has experienced good quality of life
(increased energy, improved appetite, greater mobility, and
reduced pain) since the start of treatment for longer than
expected by at least 2 standard deviations.
* Complete or partial tumor response.
Determined either by a pathology report of a biopsy showing no
evidence of disease, or by radiological, surgical, or blood
evaluation and a specialist's written opinion that evaluation
indicates disease reduction or elimination.
6. Tabulation
Using forms available from NCI, a specific
procedure is followed to record all patient data:
a. Information is carefully tabulated on a
standard Best Case Series Form.
b. Each chart selected is evaluated and results
are recorded on a Score Sheet.
c. All reasons for inclusion or exclusion are
noted on the Score Sheet and recorded on a Spread Sheet.
d. If a chart displays adequate information,
outcome criteria also are recorded on the Score Sheet and Spread
Sheet.
e. The proportion of cases submitted to cases
included in the best case series is calculated by dividing the
accepted cases by the total number of cases submitted. This
calculation provides a "discrepancy index," which is an
estimate of the accuracy of practitioners' judgments about the
success of their treatment. The amount of discrepancy due to
inadequate information or faulty outcome estimation can be
determined.

The data show that the TM-trained body
operates at a lower baseline level of activity and has
more adaptive reserves; hence, the meditator may respond
more powerfully and recover more rapidly when challenged
by stressors.
The above observations on the NRC report
on meditation are based on Orme-Johnson and Alexander's
"Critique of the National Research Council's Report
on Meditation" (1992).
The subsequent sections of this appendix
present several types of research in the same sequence in
which they are usually applied, providing guidelines to
literature reviews, descriptive and cross-cultural
studies, "best case" screening, clinical
trials, and outcomes research. These are followed first
by introductions to two sophisticated approaches to
analyzing research--meta-analysis and systematic
reviews--and then by a selected bibliography, information
on the National Library of Medicine, and useful contact
information.
Descriptive research is sometimes called
"qualitative research," but descriptive
research actually uses a mixture of qualitative and
quantitative techniques.
The design and methods chosen for
conducting research must be consistent with the
assumptions of the model used in generating the
hypothesis under study. Model fit is explained more fully
in the "Guidelines for Clinical Trials"
section.
Since preparing the best case screening
guidelines in response to a request from Congress, NCI
has reviewed three series of best cases--for nutritional
therapy (Nicholas Gonzales), antineoplastons (Stanislaw
Burzynski), and insulin potentiation therapy (Steven
Ayre). As a result of these reviews, NCI determined that
antineoplaston therapy is a suitable candidate for
clinical trials (see also the "Pharmacological and
Biological Treatments" chapter); clinical trials
began in winter 1993-94.
An example is the Hawthorne effect, the
observation that experimental subjects who are aware that
they are part of an experiment often perform better than
totally naive subjects.
The working title of the OTA report is
Searching for Evidence: The Effort to Identify Health
Care Technologies That Work.
The diagnosis of any other illness must be
similarly documented with measures appropriate to that
illness.
