“It is much more important to know what sort of patient has
a disease than what sort of disease a patient has.” Sir William Osler.
The use of guidelines in medical practice is necessary for
good patient care. Guidelines have
always been with us in practice, although it is only in recent years that the
“best practice” norms that all physicians and nurses are taught have been
formalized into guidelines. What is a
guideline? According to the Institute of Medicine (IOM) and as used by the federal government National Guideline Clearinghouse, “Clinical practice guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances.”
A recent article in the Journal of the American Medical Association points out that, to be effective, guidelines must be trusted and widely accepted. The authors discuss
that guidelines should be developed through a rigorous, standardized process so
that they are consistent and reflect the best, most up to date thinking in
order to build and to deserve trust. However even the most rigorous approaches to
guideline development will not guarantee trust if they are then used in ways that
foster suspicion. There is almost a “bait and switch” quality
to developing a guideline to assist practitioners and patients and then using
them to determine if a practitioner is high or low quality, to set
insurance coverage and to determine reimbursement.The use of the guidelines in this way can be seen as threatening and as regulating rather than assisting.
The National Heart, Lung and Blood Institute is careful topoint out in their definitions of guidelines that “The recommendations are not fixed protocols that must be followed.
Responsible clinician’s judgment on the management of patients remains
paramount. Clinicians and patients need
to develop individual treatment plans that are tailored to the specific needs
and circumstances of the patient.”
But that is not how they are applied. The various ratings tools often used by the
health plans and other third parties, can label a practitioner as a “bad doctor
“if guidelines are not adhered to. The
insurance carriers and the government payers can withhold payment if you
deviate from the guidelines. Treatments
that deviate due to a caring physician trying to “tailor to the specific needs
and circumstances of the patient” can be labeled as “experimental” or not in
keeping with the “medical policy” that governs the reimbursement and
coverage. While there are appeals
mechanisms in place, they are often difficult, time consuming, and may be
perceived by the treating doctor and patient as being biased towards the health
plan or other entity.
The use of guidelines as de facto standards for payment and
quality rating purposes has positive aspects.
For physicians as a profession, the adherence to guidelines within
certain parameters may be a proxy for quality especially in view of the lack of
other available metrics. However the erosion of trust that occurs when
they are used in that fashion is real and needs to be acknowledged and addressed.
One of the reasons that guidelines are not standards is that they do not take into account the complexities of real patients. The practice of medicine is, more often than not, driven as much by the complexity of the individual patients as it is by the complexity of the disease being treated as was noted so eloquently in the quote from William Osler above. In an article in the Annals of Internal Medicine published in December 2011, the authors defined five domains of patient complexity as reflected in the attached chart from their study.
Only one of the five domains, the “medical decision making”,
is in the realm of clinical guidelines.
Even that domain is not fully addressed by disease specific guidelines as diseases
usually do not occur in medical isolation but in the context of other chronic
illnesses, other acute illnesses and other medical risk factors that may not be
reflected in one specific medical guideline. The
patient personal characteristics, the mental health issues, both primary and secondary
due to the stress of the medical illness, as well as the very real life
socioeconomic circumstances may make the following of a guideline difficult to
impossible.
In this reality of patient complexity, clinical guidelines are
extremely valuable when used to help the patient and the doctor as long as they
engender trust. When, instead they are
seen as just interfering in good patient care by pushing a doctor into the
untenable position of adjusting to the individual needs of the patient or being
labeled as practicing poor quality care, we do all a disservice.
Guidelines are a very positive force to doctors, nurses,
other health professionals and especially to patients if they are trusted however
their use as a way to determine reimbursement and benefits coverage can
seriously erode that trust. We need to
find ways to measure physician performance and drive payment parameters without
compromising the trust needed for guidelines to be used.
