This study seeks to answer whether the availability heuristic leads physicians to utilize more medical care than is economically efficient. Do rare, salient events alter physicians' perceptions about the probability of patient harm? Do these events lead physicians to overutilize certain medical procedures? This study uses Pennsylvania inpatient hospital admissions data from 2009 aggregated at the physician level to investigate these questions. The data come from the 2009 Pennsylvania Health Care Cost Containment Council (PHC4). The study is divided into two parts. In Part I, we examine whether bad outcomes during childbirth (defined as maternal mortality, an obstetric fistula or a uterine rupture) lead physicians to utilize more cesarean sections on future patients. In Part II, we examine whether bad outcomes associated with appendicitis (defined as patient death, a perforated or ruptured appendix or sepsis) lead physicians to perform more negative appendectomies (appendectomies performed when the patient did not have appendicitis) on future patients. Overall the study does not find evidence to support the claim that the availability heuristic leads physicians to overutilize medical care on future patients. However, the study does find evidence that variations in health care utilization are strongly correlated with individual physician practice patterns. The results of the study also imply that physicians' financial incentives may be a source of variation in health care utilization.

Nursing homes have been criticized for frequent use and possible misuse of psycho-active agents. These issues are of clinical concern and policy relevance, especially since the passage of the Omnibus Budget Reconciliation Act (OBRA) of 1987. Using a sample of 419 residents, the authors examined the relationships among antipsychotic drug (AP) use, behavior, and mental health diagnoses. Only 23.2% of the residents were administered APs on a routine and/or "as-needed" basis. Based on the Multidimensional Observation Scale for Elderly Subjects (MOSES) ratings, AP users were more irritable, disoriented, and withdrawn than were nonusers. Also, AP users demonstrated agitated behaviors more frequently. Notably, AP users and nonusers differed significantly in terms of documented mental health diagnoses. Among AP users, 70.1% had documented dementia, 8.3% were psychotic or had other psychiatric disorders, and 21.6% had no mental health diagnoses. In contrast, the majority of nonusers had no mental health disorders. Logistic regression revealed that diagnostic factors, frequency of agitation, level of withdrawal, and marital status were significant predictors of AP use.
