Background: Adolescents and young adults (AYA) comprise 50% of sexually transmitted infections (STIs) diagnosed annually. AYA frequently access emergency departments (EDs) for health care. Thus, the ED could be a strategic venue for the diagnosis and treatment of STIs. Objective: Cost-effectiveness analysis examining screening strategies for Chlamydia trachomatis and Neisseria gonorrhea (CT/GC). Design: Decision analytic cost-effectiveness model. Setting: Six pediatric EDs. Participants: AYA 15 to 21 y of age seeking acute care at pediatric EDs. Interventions: 1) Usual care, 2) targeted screening (using a computerized sexual health survey), and 3) universally offered screening. Main Outcomes and Measures: Cost in 2024 US dollars and effectiveness measured as STIs detected and successfully treated. Secondary effectiveness outcome metric: quality-adjusted life-years (QALYs). The cost perspective is the direct health care sector, and the time horizon is lifelong. Results: Targeted screening was the most effective and most costly (incremental cost-effectiveness ratio [ICER] of $517 per case detected and successfully treated). In a secondary analysis using QALYs lost for long-term complications of untreated CT/GC, targeted screening had an ICER of $23,320/QALY. In this analysis, usual care was dominated, being more costly and less effective than universally offered screening. In subgroup analyses of female versus male, only cohorts using $/QALY, targeted screening remained highly cost-effective for females ($6,389/QALY) compared with universally offered screening but was not cost-effective in males. Conclusions and Relevance: Targeted screening is a highly cost-effective strategy for detecting and treating STIs in adolescents seeking pediatric ED care compared with universally offered screening, with an ICER of $517 per case detected and treated. When considering quality of life for female- versus male-only subgroups, screening for males becomes less clear.
