Comparison of medical abortion with surgical vacuum aspiration: women's preferences and acceptability of treatment.
OBJECTIVE
To assess women's preferences for, and the acceptability of, medical abortion and vacuum aspiration in the early first trimester.


METHODS
Patient centred, partially randomised trial. Medical abortion was performed with mifepristone 600 mg followed 48 hours later by gemeprost 1 mg vaginal pessary. Vacuum aspiration was performed under general anaesthesia.


METHODS
Teaching hospital in Scotland.


METHODS
363 women undergoing legal induced abortion at less than nine weeks' gestation.


METHODS
Women's preferences for method of abortion before abortion; acceptability judged two weeks after abortion by recording the method women would opt to undergo in future and by semantic differential rating technique.


RESULTS
73 (20%) women preferred to undergo medical abortion, and 95 (26%) vacuum aspiration; 195 (54%) were willing to undergo either method, and were allocated at random. Both procedures were highly acceptable to women with preferences. Gestation had a definite effect on acceptability in randomised women; at less than 50 days there were no differences, but between 50 and 63 days vacuum aspiration was significantly more acceptable.


CONCLUSIONS
Women who wish to use a particular method should be allowed their choice, regardless of gestation. Women of 50-63 days' gestation without preferences for a particular method are likely to find vacuum aspiration more acceptable. A patient centred, partially randomised trial design may be a useful tool in pragmatic research.
