Trends in the use of emergency contraception: an epidemiological study in Barcelona, Spain (1994-2002)

We conducted a retrospective review of the medical records of women requesting emergency contraception (EC) at our emergency department over a 9-year period (1994-2002). EC accounted for 5.9% of all visits (n = 95,288) and increased from 1.26% in 1994 to 9.82% in 2002 (p < 0.001). Reasons for EC were condom problems in 79.5% of cases. EC was used only once by 93% of women. The mean daily number of visits was significantly higher in August (2.46), July (2.01) and September (2.02) than in other months (p < 0.05), and was more frequent on Sunday (3.26), Saturday (2.92) and Monday (2.05) compared to other week days (p < 0.001). New Year's Day and the St. John's Night registered the highest number of visits (mean of 17.2 and 11.7, respectively), with significant differences compared to the remaining days of the year (p < 0.001).
