The ethics of selecting clinical examination procedures
by Dr. Christopher Kent
Many doctors of
chiropractic employ orthopedic and neurological examinations as the core
elements of their clinical examinations. They often do so because that is
what they were taught to do in school, and what they were tested on in their
licensing examinations. However, the fact that a procedure is popular,
taught in school, or tested on examinations does not magically confer
reliability and validity.
Walsh [1] reviewed the
available literature on orthopedic tests common in chiropractic, and
concluded: "The use of orthopedic tests has been an integral part of the
physical examination for a long time. They have remained a part of the
examination more by virtue of common use than on the basis of any scientific
demonstration of their validity and clinical significance. To make a
judgment on the clinical worth of a test, its validity, reliability,
sensitivity and specificity should ideally be known. Unfortunately, for
most, if not all, orthopedic tests, these measures have not been
determined." For more references and discussion on this issue, see: http://www.worldchiropracticalliance.org/tcj/1998/aug/aug1998kent.htm

Neurological tests in
patients with no neurological symptoms serve little purpose. Deyo [2] wrote,
"In reality, though, if the patient has no neurological symptoms, including
sciatica, in the history, the yield of this is close to zero."
A mandate to teach and
practice procedures shown to be worthless or harmful creates an ethical
problem.
Different health care
specialties say it in slightly different ways, and ACOG's statement [3] on
the matter is clear and concise: "It is unethical to prescribe, provide, or
seek compensation for therapies that are of no benefit to the patient." The
same may be said for examination procedures.
Furthermore, there are
basic ethical principles [4] that are violated when patients are misled into
believing that the examinations that they are receiving are reliable and
valid. These include:
The principle of
non‑malfeasance
*** "Primum non nocere"
‑‑ first do no harm
*** Sanctity of life
*** Calculated risk or
risk benefit
The principle of
beneficence
*** Do only that which
benefits the patient
*** Patient's welfare
as the first consideration
*** Care ‑‑
Consideration ‑‑ Competence
The principle of
veracity
*** Truth telling
*** Obligation to full
and honest disclosure
The types of harm that
may result have been described [5]:
"Non‑specific harm
(labeling). Harm caused to a patient by the transmittal of false or
misleading information that may cause emotional harm, a false sense of
security, a false sense of vulnerability, dependency, or otherwise create in
the patient a set of beliefs about their health that is manifestly untrue.
Indirect harm
(substitution). Harm caused to a patient by substituting a specific
diagnostic or therapeutic procedure whose safety, therapeutic effectiveness,
or diagnostic utility is either unknown or is known to be unsafe,
ineffective, of no diagnostic utility, for a diagnostic or therapeutic
procedure of known safety, effectiveness, or diagnostic utility."
Finally, a doctor owes
legal duties to a patient. In Smith v. Yohe [6], the Pennsylvania Supreme
Court held, "If a physician, as an aid to his diagnosis, i.e., his judgment,
does not avail himself of the scientific means and facilities open to him
for the collection of the best factual data upon which to arrive at his
diagnosis, the result is not an error of judgment but negligence in failing
to secure an adequate factual basis upon which to support his diagnosis or
judgment."
If your clinical
objective is the detection and correction of vertebral subluxations, and you
are relying on orthopedic and neurological examination findings, you would
do well to consider whether those examinations have been shown to be
reliable and valid for that purpose.
