| Abstract: | BackgroundThis study evaluates the willingness of women presenting for emergency contraception (EC) to enroll in a study offering the copper intrauterine device (IUD) or oral levonorgestrel (LNG) and follows up the two groups for 6 months after EC administration to compare use of an effective method of contraception.Study DesignThis prospective observational study offered these two methods to women presenting for EC. The primary outcome was use of an effective method of contraception 6 months after presenting for EC.ResultsThirty-four women (60%) chose oral LNG and 23 (40%) chose the copper IUD. One month after presenting for EC, 21 (96%) of 22 in the IUD group were still using the IUD and all 22 were using an effective method of contraception (efficacy ≥92%). In the LNG group, 13 (52%) of 25 were using an effective method of contraception (p<.001). At 6 months, 9 (69%) of 13 IUD users and 11 (52%) of 21 oral LNG EC users were using an effective method (p=NS).ConclusionWomen presenting for EC were willing to enroll in a study offering the copper IUD or oral LNG. |
