Publication Eleven-year descriptive analysis of closed court verdicts on medical errors in Spain and Massachusetts
(BMJ Publishing Group, 2016) Giraldo, Priscila; Sato, Luke; Martínez-Sánchez, Jose M; Comas, Mercè; Dwyer, Kathy; Sala, Maria; Castells, XavierObjectives: To evaluate and compare the characteristics of court verdicts on medical errors allegedly harming patients in Spain and Massachusetts from 2002 to 2012. Design, setting and participants We reviewed 1041 closed court verdicts obtained from data on litigation in the Thomson Reuters Aranzadi Westlaw databases in Spain (Europe), and 370 closed court verdicts obtained from the Controlled Risk and Risk Management Foundation of Harvard Medical Institutions (CRICO/RMF) in Massachusetts (USA). We included closed court verdicts on medical errors. The definition of medical errors was based on that of the Institute of Medicine (USA). We excluded any agreements between parties before a judgement. Results: Medical errors were involved in 25.9% of court verdicts in Spain and in 74% of those in Massachusetts. The most frequent cause of medical errors was a diagnosis-related problem (25.1%; 95% CI 20.7% to 31.1% in Spain; 35%; 95% CI 29.4% to 40.7% in Massachusetts). The proportion of medical errors classified as high severity was 34% higher in Spain than in Massachusetts (p=0.001). The most frequent factors contributing to medical errors in Spain were surgical and medical treatment (p=0.001). In Spain, 98.5% of medical errors resulted in compensation awards compared with only 6.9% in Massachusetts. Conclusions: This study reveals wide differences in litigation rates and the award of indemnity payments in Spain and Massachusetts; however, common features of both locations are the high rates of diagnosis-related problems and the long time interval until resolution.
Publication Electronic Health Records and Malpractice Claims in Office Practice
(American Medical Association (AMA), 2008-11-24) Virapongse, Anunta; Bates, David; Shi, Ping; Jenter, Chelsea A.; Volk, Lynn A.; Kleinman, Ken; Sato, Luke; Simon, StevenBackground: Electronic health records (EHRs) may improve patient safety and health care quality, but the relationship between EHR adoption and settled malpractice claims is unknown.
Methods: Between June 1, 2005, and November 30, 2005, we surveyed a random sample of 1884 physicians in Massachusetts to assess availability and use of EHR functions, predictors of use, and perceptions of medical practice. Information on paid malpractice claims was accessed on the Massachusetts Board of Registration in Medicine (BRM) Web site in April 2007. We used logistic regression to assess the relationship between the adoption and use of EHRs and paid malpractice claims.
Results: The survey response rate was 71.4% (1345 of 1884). Among 1140 respondents with data on the presence of EHR and available BRM records, 379 (33.2%) had EHRs. A total of 6.1% of physicians with an EHR had a history of a paid malpractice claim compared with 10.8% of physicians without EHRs (unadjusted odds ratio, 0.54; 95% confidence interval, 0.33-0.86; P = .01). In logistic regression analysis controlling for sex, race, year of medical school graduation, specialty, and practice size, the relationship between EHR adoption and paid malpractice settlements was of smaller magnitude and no longer statistically significant (adjusted odds ratio, 0.69; 95% confidence interval, 0.40-1.20; P = .18). Among EHR adopters, 5.7% of physicians identified as “high users” of EHR had paid malpractice claims compared with 12.1% of “low users” (P = .14).
Conclusions: Although the results of this study are inconclusive, physicians with EHRs appear less likely to have paid malpractice claims. Confirmatory studies are needed before these results can have policy implications.
