Bottom Line: Performing an abortion in an ambulatory surgery center instead of in an office-based setting was not associated with a significant difference in abortion-related complications such as infection and hemorrhage.
Why The Research Is Interesting: Multiple states have laws requiring abortion facilities to meet ambulatory surgery center (ASC) standards. More than 95 percent of abortions are provided in non-hospital-based settings in abortion clinics, other clinics or physician offices. Limited evidence exists about abortion-related complications after an abortion at performed at an ASC compared with an office-based setting.
Who and When: 49,287 women with private health insurance who had 50,311 abortions in an ASC or in an office-based setting from 2011 to 2014
What (Study Measures and Outcomes): Facility type where the abortion was performed (ASC vs office-based setting, which included abortion clinics, other clinics and physician offices) (exposures); any abortion-related complication (such as perforation of the uterus, infection, hemorrhage, tissue that remains in the uterus) within six weeks after an abortion (outcomes).
How (Study Design): This was an observational study. Researchers were not intervening for purposes of the study and cannot control all the natural differences that could explain the study findings.

Study Limitations: Only included abortions paid for by private insurance so the findings may not be generalizable to all abortions in the United States
