Abstract
AIM
Medical errors are critical in obstetrics and gynecology (OB/GYN) and contribute to high litigation risks. However, few studies have examined system and diagnostic errors as potential preventable problems. This study aimed to enhance medical safety and reduce litigation by identifying and addressing key contributory factors.
METHODS
We retrospectively searched the national Japanese malpractice claims database for OB/GYN cases between 1961 and 2017. We evaluated provider characteristics and background information of the patients (plaintiffs). The main outcome was litigation (acceptance or rejection) in the final judgment. Using multivariable logistic regression models, we assessed the associations between medical malpractice variables (system and diagnostic errors, facility size, situation, place, time, and clinical outcomes) and litigation outcomes (acceptance).
RESULTS
Overall, 344 malpractice claims were analyzed. Among these, 277 (80.5 %) were obstetric, and 67 (19.5 %) were gynecological. Of the obstetric cases, 193 were perinatal, and 84 were maternal. Malpractice claims were accepted (OB-GYN losses) in 185 cases (53.8 %). In multivariable analyses, system errors (odds ratio 97.4, 95 % confidence interval 35.2-270.0), diagnostic errors (odds ratio 4.5, 95 % confidence interval 1.8-11.3), and clinic (odds ratio 2.7, 95 % confidence interval 1.2-4.8) had a significant statistical association with accepted claims.
CONCLUSION
System errors, diagnostic errors, and clinics were significantly associated with acceptance claims. These findings underscore the necessity of addressing modifiable factors at the physician level and within the healthcare management system to enhance patient safety and reduce litigation risks, thereby ensuring a safer and more reliable healthcare environment for patients and medical professionals.
