Objective This study evaluated the implementation status of morbidity and mortality conferences in internal medicine specialty training programs in Japan. Methods This cross-sectional study surveyed hospitals in Japan with certified internal medicine specialty training programs. Program directors or equivalently responsible physicians managing certified internal medicine training programs were invited to participate in this study (n=619). Materials Data were collected using an online questionnaire that included questions about the number of morbidity and mortality conferences, types of cases covered, collaboration of the patient safety section and other health professions, and whether or not the conferences were conducted by a subspecialty department-led or program-based. Results Responses were received from 123 hospitals (19.8% response rate), of which 59 (48%) had some form of internal medicine morbidity and mortality conference in place. The average number per year was 9.63 (standard deviation: 18.12). Hospitals with morbidity and mortality conferences in subspecialty departments held significantly more conferences than X (please define X). Furthermore, the involvement of the patient safety department tended to be associated with holding more conferences. Autopsy rates were significantly higher in hospitals with program-based internal medicine morbidity and mortality conferences than subspecialty-led. Conclusion Internal medicine specialty training hospitals had more morbidity and mortality conferences than previously reported. Program-based morbidity and mortality conferences in internal medicine are associated with higher autopsy rates and may lead to an organizational reporting culture and lifelong learning attitudes that support patient safety. Collaboration with organizational management sections, such as patient safety, would be effective in implementing these conferences in internal medicine training programs.

Objectives Medical litigation resulting from diagnostic errors leads to lawsuits that are time-consuming, expensive, and psychologically burdensome. Few studies have focused on internists, who are more likely to make diagnostic errors than others, with assessments of litigation in terms of system and diagnostic errors. This study explored factors contributing to internists losing lawsuits and examined whether system or diagnostic errors were more important on the outcome. Methods Data regarding 419 lawsuits against internists closed between 1961 and 2017 were extracted from a public Japanese database. Factors affecting litigation outcomes were identified by comparative analysis focusing on system and diagnostic errors, environmental factors, and differences in initial diagnoses. Results Overall, 419 malpractice claims against internists were analyzed. The rate of lawsuits being decided against internists was high (50.1%). The primary cause of litigation was diagnostic errors (213, 54%), followed by system errors (188, 45%). The foremost initial diagnostic error was "no abnormality" (17.2%) followed by ischemic heart disease (9.6%) and malignant neoplasm (8.1%). Following cause-adjustment for loss, system errors were 21.37 times more likely to lead to a loss. Losses were 6.26 times higher for diagnostic error cases, 2.49 times higher for errors occurring at night, and 3.44 times higher when "malignant neoplasm" was the first diagnosis. Conclusions This study found that system errors strongly contributed to internists' losses. Diagnostic errors, night shifts, and initial diagnoses of malignant neoplasms also significantly affected trial outcomes. Administrators must focus on both system errors and diagnostic errors to enhance the safety of patients and reduce internists' risk exposure.
