Evidence-based physicians' dressing: a crossover trial

Med J Aust 2002; 177 (11): 681-682.

Summary

Objective: To describe the effect of physicians' dress on patient confidence and trust.

Design: A prospective crossover trial involving physicians dressed in "respectable" versus "retro" attire.

Setting: A general medicine ward at a tertiary hospital.

Participants: 12 male general physicians and 1680 patients.

Main outcome measures: Patient trust and confidence as measured by a questionnaire mailed after hospital discharge.

Results: Formal attire was correlated with higher patient confidence and trust. Nose rings were particularly deleterious to patients' reported trust and confidence. A minimum threshold of two items of formal attire (dress pants, dress shirt, tie, or white coat) were necessary to inspire a reasonable amount of confidence; this is the NND (number needed to dress).

Conclusions: We highlight the need for more research into the effects of physician dress, and coin the term "evidence-based dressing".
