Association of Provider Specialty With Abortion-Related Morbidity and Adverse Events Among Patients Having Procedural and Medication Abortions

Objective: Since abortion was legalized throughout the United States in 1973, states have passed restrictive abortion policies, including permitting only obstetrician-gynecologist physicians (OBGYNs) to provide abortions. We are unaware of any research that directly compares patient safety-related outcomes by physician specialty. In this study, we compared major and any abortion-related morbidity and adverse events in abortion care provided by physicians of other specialties versus OBGYNs. Study Design: Using the IBM Watson Health MarketScan claims database, we identified privately insured individuals who had an induced abortion between January 1, 2011, and December 31, 2014. The primary outcome was major abortion-related morbidity or adverse events, and the secondary outcome was any abortion-related morbidity or adverse events occurring within 6 weeks of the abortion. Results: The study cohort included 34,764 patients who had 35,407 abortions—4,843 (13.7%) abortions provided by physicians of other specialties and 30,564 (86.3%) abortions provided by OBGYNs. Major and any abortion-related morbidity or adverse event occurred in 115 (0.3%) and 1,271 (3.6%) of 35,407 of abortions, respectively. In adjusted analyses, there was no statistically significant difference in major abortion-related morbidity or adverse events comparing physicians of other specialties versus OBGYNs (adjusted odds ratio, 1.02; 95% confidence interval, 0.59–1.75), and no statistically significant difference in any abortion-related morbidity or adverse events comparing physicians of other specialties versus OBGYNs (adjusted odds ratio, 0.91; 95% confidence interval, 0.77–1.09). Conclusions: There were no differences in abortion-related morbidity or adverse events by physician specialty. Our findings do not support state laws limiting abortion care to OBGYN physicians.
