This study analyzes the incidence of medical malpractice claims since 1976, using data drawn from the 1982 core survey of the American Medical Association's Socioeconomic Monitoring System. The data show that, on average, physicians incurred twice as many claims per year in the years 1976 to 1981 as they did during their careers prior to that period. Using Tobit analysis, we find the annual frequency of claims to be greater among surgeons, obstetricians and gynecologists (OBGs), physicians in group practice, and physicians in states which apply the legal doctrine of informed consent. In addition, we find that the number of years since medical residency is positively related to physicians' claims incidence during the first 27 years of practice, and that OBGs and medical specialists who spend more time with their patients per office visit incur fewer claims.
本研究利用从美国医学协会社会经济监测系统1982年核心调查中提取的数据，分析了自1976年以来医疗事故索赔的发生率。数据显示，平均而言，1976年至1981年期间，医生每年发生的索赔次数是该时期之前职业生涯的两倍。通过托比特分析，我们发现外科医生、妇产科医生（OBG）、团体执业医生以及适用知情同意法律原则州的医生每年的索赔频率更高。此外，我们发现，从完成住院医师培训后的年数与医生执业头27年的索赔发生率呈正相关，而且每次门诊花费更多时间与患者相处的妇产科医生和医学专家发生的索赔较少。
