An "evidence based" approach to the practice of medicine has been the subject of some controversy over the years, with antagonists and protagonists both claiming the path to truth. But there may well be other approaches to practice. Isaacs and Fitzgerald may have provided some insight into these "other paradigms" in their 1999 BMJ publication Seven Alternatives to Evidence Based Medicine http://www.bmj.com/cgi/content/full/319/7225/1618).
Here are the seven alternative bases of clinical practice identified (reprinted with permission from the authors):
Eminence based medicine: The more senior the colleague, the less importance he or she placed on the need for anything as mundane as evidence. Experience, it seems, is worth any amount of evidence. These colleagues have a touching faith in clinical experience, which has been defined as "making the same mistakes with increasing confidence over an impressive number of years." The eminent physician's white hair and balding pate are called the "halo" effect.
Vehemence based medicine: The substitution of volume for evidence is an effective technique for brow beating your more timorous colleagues and for convincing relatives of your ability.
Eloquence based medicine: The year round suntan, carnation in the button hole, silk tie, Armani suit, and tongue should all be equally smooth. Sartorial elegance and verbal eloquence are powerful substitutes for evidence.
Providence based medicine: If the caring practitioner has no idea of what to do next, the decision may be best left in the hands of the Almighty. Too many clinicians, unfortunately, are unable to resist giving God a hand with the decision making.
Diffidence based medicine: Some doctors see a problem and look for an answer. Others merely see a problem. The diffident doctor may do nothing from a sense of despair. This, of course, may be better than doing something merely because it hurts the doctor's pride to do nothing.
Nervousness based medicine: Fear of litigation is a powerful stimulus to over investigation and overtreatment. In an atmosphere of litigation phobia, the only bad test is the test you didn't think of ordering.
Confidence based medicine: This is restricted to surgeons.
