Impact of post-visit contact on emergency department utilization for adolescent women with a sexually transmitted infection

Abstract

Study objectives: To understand Emergency Department (ED) utilization patterns for women who received sexually transmitted infection (STI) testing and explore the impact of post-visit telephone contact on future ED visits. Design, setting, participants: We performed a secondary analysis on a prospectively collected dataset of ED patients ages 14-21 years at a children's hospital. Interventions and main outcome measures: The dataset documented initial and return visits, STI results, race, age and post-visit contact success (telephone contact ≤7 days of visit). Logistic regression was performed identifying variables that predicted a return visit to the ED, a return visit with STI testing, and subsequent positive STI results. Results: Of 922 women with STI testing at their initial ED visit, 216 (23%) were STI positive. One-third (315/922) returned to the ED, 15% (141/922) returned and had STI testing, and 4% (38/922) had a subsequent STI. Of 216 STI-positive women, 59% were successfully contacted. Of those who returned to the ED, age ≥ 18 and Black race were associated with increased STI testing at a subsequent visit. Successful contact reduced the likelihood of STI testing at a subsequent ED visit (OR 0.28, 95% CI 0.01-0.8), and ED empiric antibiotic treatment had no effect on subsequent STI testing. Conclusion: Contacting women with STI results and counseling them regarding safe sex behaviors may reduce the number of ED patients who return with symptoms or a new exposure necessitating STI testing. The high STI prevalence and frequent return rate suggest that ED interventions are needed.
