200 Being a Doctor After Being a Patient tendency may contribute to these physician-patients seeking more ag- gressive treatment. Trainees in particular seemed overly influenced by observations of rare but severe complications of treatments or disease in patients, though the odds of such events remained small. For example, Suzanne, who had bipolar disorder, refused to take a drug because of its risk of causing Stevens-Johnson syndrome, which she had witnessed in a patient. My psychiatrist suggested Lamictal, but my answer was ‘no,’ be- cause of Stevens-Johnson syndrome: I met one patient who can’t move her arm now. That’s enough for me! Because she had less clinical experience, such an event may have influenced Suzanne more than it would older physicians. In fact, the statistical likelihood of Lamictal causing Stevens-Johnson is very low. However, as Tversky and Kahnemann (2) have described, individuals are biased in assessing risks, using, for example, an ‘‘availability heuristic’’ through which they disproportionately weigh vivid personal experiences of bad outcomes more than the actual probability of such outcomes occurring. Trainees appeared to have particular difficulty integrating observations of rare but serious complications with epidemiological data that such extreme complications may in fact be highly unusual. It is not surprising that ‘‘medical student disease’’ results among trainees, who ignore base- line rates of conditions in assessing minor symptoms. The degree to which such misassessments hamper subsequent treatment decisions is not clear, and needs to be probed by researchers. But the fact that a rare but trau- matic event occurred can shape views among physicians (particularly if young) of the odds of its recurring. Indeed, extended, cumulative clin- ical experiences can counter tendencies to overweigh uncommon but traumatic events. Some doctors felt fatalistic about their own condition, seeing their disease kill their patients. Stuart, the internist with HIV who was now teaching at the university, felt less sanguine about his own prognosis than he would have otherwise. ‘‘It was a problem seeing a lot of sickness with patients. So I was pretty pessimistic about my own outcome. I assumed that in five years, I’d be facing severe disease and death.’’ These doctors had strong views as to whether they would ‘‘overcome the odds’’ or fall victim to
