How Do Physicians Provide Statistical Information about Antidepressants to Hypothetical Patients?

Abstract

BackgroundLittle is known about how physicians pro- vide statistical information to patients, which is important for informed consent.MethodsIn a survey, obstetricians and gynecologists (N = 142) received statistical information about the benefit and side effects of an antidepressant. They received information in various formats, including event rates (antidepressant v. placebo), absolute risks, and relative risks. Participants had to imagine 2 hypothet- ical patients, 1 for whom they believed the drug to be safe and effective and 1 for whom they did not, and select the information they would give those patients. We assessed whether the information they selected for each patient was complete, transparent, interpretable, or persuasive (i.e., to nudge patients toward a particular option) and compared physicians who gave both patients the same information with those who gave both patients different information.ResultsA similar proportion of physicians (roughly 25% each) selected information that was 1)complete and transparent, 2) complete but not transparent, 3) not interpretable for the patient because necessary com- parative information was missing, or 4) suited for nudging. Physicians who gave both patients the same information (61% of physicians) more often selected at least complete information, even if it was often not transparent. Physicians who gave both patients different information (39% of physi- cians), in contrast, more often selected information that was suited for nudging in line with the belief they were asked to imagine. A limitation is that scenarios were hypo- thetical.ConclusionsMost physicians did not provide complete and transparent information. Clinicians who pre- sented consistent information to different patients tended to present complete information, whereas those who varied what information they chose to present appeared more prone to nudging.
