The current status of placebo in hospital practice.

Despite a voluminous literature on the topic of placebo, there has been little documentation of either actual clinical practice of prescribing placebo or the attitudes that surround it. Through a questionnaire survey of all head nurses of clinical units in one health services area of Connecticut, data were obtained on current practices regarding placebo use in the natural hospital setting. Multiple reasons for placebo use in the natural hospital setting. Multiple reasons for placebo use were given, and it was noted that patients receiving placebo tended to be viewed in certain ways. The effectiveness of placebo in symptom relief was reported as nearly double that reported in the experimental literature. Methodologic issues of the study and of placebo investigation, in general, are discussed. Because common clinical problems appear to generate most instances of placebo use, several issues pertinent to medical education are raised. Some future directions for placebo research are proposed.
