The gentle radical

In Canada, family practice is the epitome of generalist clinical practice

Of all branches of medicine, general practice is the most variable. Each practice is a reflection of the character of the practitioner, the type of patient he serves, and the district in which he works.⁵

Family medicine has no predetermined limits to its scope. Some generalist disciplines, such as internal medicine and pediatrics, narrow their scope based on patient age. Others, such as obstetrics, limit their scope based on patient sex. Yet others, such as emergency medicine, narrow their scope based on acuity. Family physicians commit to work with any patient with any problem to the limits of their competence not only throughout the duration of a particular illness, but also in between illness episodes. A continuous therapeutic relationship of this nature is unique to family medicine. If [we family physicians] are to fill our place, it is crucial that our commitment be unconditional; patients should feel confident that they will never be told “this is not my field.”⁹

Generalism has a scientific basis

Many patients have illnesses that defy differentiation into well-known disease categories. 25–50% of illness in family practice remains undifferentiated, even after assessment.⁹

Diagnoses of life-threatening conditions that should not be delayed make up the minority of cases in a generalist office. Clinical acumen and a sound differential diagnosis will assist the practitioner in determining which patients cannot safely wait before investigation or treatment of their symptoms. For most other patients, deciding how long to wait before pursuing a firm diagnosis is dependent on various patient and provider factors, including the doctor-patient relationship.

In a general practice, the prevalence of a specific disease will be much lower than in an emergency or hospital population. As a result, the predictive value of diagnostic tests is much lower and the value of such tests in the general practice setting is “markedly overestimated.”¹⁰ Dogged pursuit of a precise diagnosis, looking to “rule out an organic cause” at all costs, might prove futile, wasteful, or even harmful to the patient. As technology advances, the costs and potential risks to the patient, such as risks of investigative tests and side effects of medications, increase considerably.²

To address the limitations of diagnostic tests in their practice setting, expert generalists employ the scientific “watch and wait” approach.^11,12 Purposefully and carefully allowing natural history to influence the pretest likelihood of disease is soundly based on principles of clinical epidemiology. The generalist approach is “neither greater nor lesser than that of the specialist, just different.”¹³ According to Rosser and colleagues, “If more people understood the concept and skilled appreciation of watchful waiting in family practice, the more valued would be the excellent family physician.”¹⁰

Generalists are often diagnosticians, sometimes curers, but always healers

To be a healer is to help patients find their own way through the ordeal of their illness to new wholeness.⁹

Many patients leave a consultation with their family physicians accepting diagnostic and prognostic uncertainty. Others fear what might be lurking beneath or the prospect of living indefinitely with their symptoms. As the number of chronic diseases in a particular patient increases, the number of potential symptoms also increases, as does the iatrogenic burden from the medications these patients are inevitably prescribed.

Easing the patient’s suffering is an important part of the generalist’s work. In addition to the patient’s physical symptoms, there is also fear of the unknown, frustration about reduced function, guilt about burdening others, and overall increased stress in the patient’s daily life. Patients’ personal habits might also be contributing to their problems. Skillful incursion in these areas is the domain of the healer. Done properly, it can be in and of itself a powerfully therapeutic intervention.

Generalist leaders must impress upon policy makers that overemphasis on measurable physician performance indicators will come at a cost. If physicians are reduced to assembly-line technicians, much of the real healing work of the person-centred generalist will be in jeopardy.

Society increasingly expects specialist attention, perhaps at their peril

Many of us live in societies that value excellence. The idea of excellence, however, is the development of a single talent to its utmost limit …. In deciding to be generalists, family physicians have renounced one-sided development in favor of balance and wholeness. They do pay a price for this: in lack of recognition by a society that is itself unbalanced.²

Specialization was born in the industrial revolution and initially had more of an economic application. Focusing labourers to perfect one aspect of the manufacturing process had obvious effects on productivity and, therefore, economic benefits.¹⁴

Highly trained specialists are necessary in medicine, but they must be used appropriately. Whereas increased numbers of generalists is associated with improved population health outcomes, increased numbers of specialists has a neutral or opposite effect.¹⁵ The medical industry, media, and public personalities perpetuate a myth that if one has an unresolved symptom or an uncured disease, it is because he or she has been denied the best specialist or the latest test. This message fosters an unrealistic expectation and demand for services that society simply cannot afford. Generalism requires societal embrace of an untidy, indefinite, lethargic and risky practice of medicine …. Homo sapiens has come to expect certain salvation, not uncertain palliation.¹²

Demands on generalists are constantly shifting

For most of this century, the typical primary care professional has been a generalist practitioner.¹⁶

The generalist has been, up to the 20th century, a solo practitioner in office-based practice. In Canada this landscape shifted considerably toward group practice and multidisciplinary teams. Contributing to this shift is the trend for more patient care to happen outside of hospitals, with sicker patients increasingly being cared for in the community.

Although the precise effect of such shifts remains to be determined, working in teams would appear to have advantages for everyone, in particular the patient. However, there are some risks. We must ensure that care is not fractionated within primary care teams with each team member being responsible for only one small piece of the patient’s care. The generalist physician remains ultimately responsible for the whole person and must manage and coordinate the total treatment activity of the entire team.

Generalists face challenges, including from within family medicine

By virtue of special interest or training, a physician may have knowledge that is not shared by colleagues … the important point is that this should not lead to fragmentation.²

There is considerable interest among new family medicine graduates in pursuing additional training in enhanced-skills, third-year fellowship programs. The College of Family Physicians of Canada has recently formed groups of family physicians with enhanced competence in focused areas of practice. Some of the approximately 20 special interest groups are proposing certificates of competence in their interest areas.

One qualitative study of family medicine residents¹⁷ showed that residents believed that “specialization” was a solution to the “burden” of managing a broad scope of practice. We know that of the 77% of those family physicians who received Certification in emergency medicine from the College of Family Physicians of Canada who are still practising emergency medicine, 59% are practising emergency medicine exclusively.¹⁸

Starfield and Gervais¹¹ express concern that specialism within generalism risks creating increased demand for specialist, disease-oriented care as opposed to whole-person, patient-centred care. They argue that enhanced-skills training within family medicine should focus on issues central to the work of the generalist including areas such as unexplained symptoms and difficult patients.

Generalist skill needs to be modeled for learners to engage

To make ourselves effective teachers ... we must learn to analyze, describe and justify the many intuitive judgments we make in the course of our day’s work.¹⁹

There are enormous opportunities in medical generalism for both faculty development and other valuable and meaningful scholarly pursuits such as writing essays and letters to journals, challenging residents to develop sound research questions, and having proven research teams competing for grants.²⁰ Faculty must excite learners, particularly family medicine residents, about the essence and value of their craft: competence in dealing with undifferentiated illness, evidence-based clinical evaluations, balancing the use of watchful waiting, judicious use of investigations, and knowledge of generalizable research findings. Faculty ought to tackle head-on what Ian McWhinney called common myths about generalists¹⁶ with which our learners inevitably wrestle: that they have to “know everything”; that the specialist will always “know more”; that specializing will eliminate uncertainty; that new science always leads to more useful information; and that error is usually caused by lack of information.

Family physicians require particular learning to be effective generalists

Each defining element of the generalist (Box 1)⁴ can be part of an organized learning process for medical students and residents and even doctors in professional development workshops. Examples could include how common illnesses present before declaring themselves: the pain before the rash in an outbreak of shingles; the fever and sweats of a possible infection declaring themselves as the first signs of lymphoma, as uncommon lymphoma shows itself during a management plan of watchful waiting. Similarly they could include a debate on how to recognize and manage new emotional stress in a typically healthy young parent. Each element deserves particular consideration in a series of learning competencies that strengthen the generalist capacity of the young physician.

Family physicians are expert clinicians, not specialists

We are not specialists, unless the term becomes meaningless.⁹

There has been much debate^21,22 about whether family medicine should be regarded as a medical specialty. In Canada the issue for the most part is one of professional status. In some jurisdictions there is also a considerable financial benefit to being identified as a specialist.

All specialists have boundaries around who they serve, whether it is by patient age or sex, illness acuity, organ involvement, or a need for technology. Family doctors have no such boundaries. Are they specialists? No. They are generalists: expert clinicians, masters of the undifferentiated clinical presentation, managers of uncertainty, healers, collaborators, scientists, and role models. They are portable and adaptable. Now more than ever the sustainability of our health care system depends on their unique knowledge, skill, and attitude.
