The case against "the evidence": a different perspective on evidence-based medicine

Abstract

Background: An evidenced-based approach to psychiatry is playing an increasingly prominent role in treatment decision-making for individual patients and for populations. Many doctors are now critical of the emphasis being placed on "the evidence" and concerned that clinical practice will become more constrained.

Aims: To demonstrate that evidence-based medicine is not new, sources of evidence are limited and psychosocial aspects of medicine are neglected in this process.

Method: Some of the literature is reviewed. Ideas and arguments are synthesised into a critical commentary.

Results: These are considered under four headings: evidence-based medicine is not new; what evidence is acceptable; the doctor as therapist; and the emergence of a new utilitarian orthodoxy.

Conclusions: It is agreed that a degree of professional consensus is necessary. However, too great an emphasis on evidence-based medicine oversimplifies the complex and interpersonal nature of clinical care.
