BackgroundInterventions aimed at reducing teen pregnancy rates in the United States have focused on clinics and schools. Teens disproportionately seek care in emergency departments (EDs), making these an important and understudied arena for interventions to prevent subsequent unwanted pregnancies. Establishing the risk of subsequent pregnancy (SP) in this population is a necessary prelude to effective interventions. Therefore, we set out to measure the incidence and imminence of pregnancy in sexually active teens after an ED visit.MethodsA medical record review was conducted in an urban medical center with a general ED and a pediatric ED. Subjects were included if they were female individuals aged 13 to 19 years, were tested for gonorrhea and chlamydia in the EDs from 2004 to 2006, and were patients in the primary care clinics at the affiliated institution. Subsequent pregnancies were determined from the primary clinic charts. The duration of follow-up was 4 years.ResultsThree hundred ninety-eight subjects were included in the study. The mean age at ED visit was 17.3 years. A majority (70.1%) had a documented SP. For patients with an SP, the mean interval from ED visit to conception was 15.8 months. Patients who had an SP were significantly more likely to be an ethnic minority, to have tested positive for gonorrhea, and to have visited the adult ED.ConclusionsIn this population of sexually active teens, 70.1% became pregnant within 4 years of being tested for gonorrhea and chlamydia in the ED. The encounter in the ED represents a potential opportunity for pregnancy-prevention interventions.
