Abstract
Compared with other industries, health care is a high-risk industry. In this study, two national dala sets on patient claims and a survey of improvement efforts in Swedish health care were used to investigate the linkage between how health care managers perceive their performance regarding adverse medical events and their performance as reflected in patient malpractice claims rates. The departments' focus on patient safety issues in their improvement efforts was also evaluated. Our results show that Swedish health care department managers underestimate their departments' frequency of adverse medical events relative to that of similar units. Also, there is no correlation between the managers' perception of adverse medical events and their actual frequency of patient malpractice claims. More research is needed on the use of patientgenerated malpractice claims and claims rates to promote a higher awareness of the magnitude of the safety problems in health care.
