A cohort of women aged 14–29 in 1993 was identified from the General Practice Research Database and followed up for four years. Patient files were searched for evidence of the use of emergency contraception and regular contraception. Of the 95 007 women, 15 105 had received emergency contraception during the study period.
There was a small year on year increase in uptake of emergency contraception between 1994 and 1997. Only 4% of emergency contraception users received emergency contraception more than twice in any year. More than 70% of those who had no previous regular contraception record had used regular contraception within one year of using emergency contraception. Teenagers were more likely than other age groups to use emergency contraception, repeat users of emergency contraception, and fail to start regular contraception after the first use of emergency contraception until later in the study period.
These results disprove the notion of widespread repeated use of emergency contraception. They show that the provision of an emergency contraception service does not fail to initiate regular contraception or abandonment of regular contraception; instead, they demonstrate many women using regular contraception for the first time after emergency contraception.
