Evidence-based physicians' dressing: a crossover trial.

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".

Interns are from Venus, consultants are from Mars: differential perception among clinicians.

OBJECTIVE: To test for the presence of sex-based differences in perception (the notion that men and women "think" differently, and that differences in perception are biologically based) among healthcare professionals. DESIGN: Prospective survey. SETTING AND PARTICIPANTS: 90 medical personnel at a tertiary care hospital in Newcastle, NSW. INTERVENTION: Healthcare professionals were shown two pictures that could be interpreted as depicting either a young or an old person, and a word that could be seen as geometric shapes. MAIN OUTCOME MEASURES: The effects of sex, age, seniority, and specialisation in relation to the first impression of the image, the ability to change one's perception, and the speed of perception. RESULTS: Contrary to popular opinion, male physicians were more likely to perceive the older figures, and just as likely as women to be able to change their perception. Surgeons and junior staff were more likely to see, as well as being faster to form, an impression requiring abstract thought, and were more able to change their perceptions. CONCLUSIONS: Traditional sex stereotypes do not apply to medical personnel, but other age-based stereotypes, and professional rivalries (medical versus surgical) may have some empiric basis.

Patient-oxygen dissociation curves: surveying the spectrum of oxygen-delivery methods.

OBJECTIVE: To describe the spectrum of oxygen-delivery methods. DESIGN: Clinical audit. SETTING: Medical wards of a tertiary referral teaching hospital in August 2004. PARTICIPANTS: 98 medical patients receiving supplemental oxygen. RESULTS: Of the 98 patients, 40 were not receiving oxygen by customary methods. In classifying the patterns of oxygen delivery, we describe the transcephalic, submental, and (inadvertent) rectal approaches, as well as lachrymal insufflation and the "Venturi cravat". We also describe novel oxygen-weaning methods, including the half-wean, reverse wean, and placebo wean. CONCLUSIONS: Many patients receive oxygen by unconventional methods. We postulate that this is evidence of a renewed interest in the historical routes of oxygen delivery.
