Obstet Gynecol. 2007;109(1):181.
OBJECTIVE: We systematically reviewed data on effects of increased access to emergency contraceptive pills on pregnancy rates and use of the pills.
DATA SOURCES: We searched MEDLINE, POPLINE, EMBASE, and LILACS, and we consulted with experts.
METHODS OF STUDY SELECTION: We included studies that compared the effect of different levels of access to emergency contraceptive pills on pregnancy rates, use of the pills, and other outcomes.
TABULATION, INTEGRATION, AND RESULTS: Of the 717 articles identified, we selected 23 for review. The studies included randomized trials, cohort studies, and evaluations of community interventions. The quality of these studies varied. In all but one study, increased access to emergency contraceptive pills was associated with greater use. However, no study found an effect on pregnancy or abortion rates.
CONCLUSION: Increased accessto emergency contraceptive pills enhances use but has not been shown to reduce unintended pregnancy rates. Further research is needed to explain this finding and to define the best ways to use emergency contraception to produce a public health benefit.
