Instituting medical abortion services: changes in outcome and acceptability related to provider experience

A prospective case series carried out at 34 Planned Parenthood sites studied the safety, efficacy, and acceptability of medical abortion with methotrexate and misoprostol in 1973 women. Women with pregnancies of 26 to 49 gestational days were given methotrexate followed by vaginal misoprostol. Eighty-one percent of women had documented complete medical abortions; abortion was not confirmed by examination in 6%, and 13% had documented suction curettage. The rate of suction curettage decreased with site experience, from 17% during the first 20 procedures to 10% at sites that had performed more than 50. Sites that had previous experience with either methotrexate or mifepristone medical abortion had a rate of 9% after they had performed at least 50 procedures. Exit interviews with 755 of the 902 women having abortions in the first year inquired about the level of comfort with the abortion and its overall acceptability. Women's satisfaction with the side effects did not directly correlate with site experience. Overall satisfaction with the abortion experience was related to whether the women had complete medical abortions or suction curettage.
