Trends in Emergency Department Visits among Adolescents with Abnormal Uterine Bleeding

Study Objective To explore trends over time in the utilization of the Emergency Department (ED) for adolescents with abnormal uterine bleeding (AUB). Design Retrospective cross-sectional study. Setting Nationwide Emergency Department Sample database (Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, Rockville, MD). Participants Subset of adolescents aged 10-19 years from overall cohort of women aged 10-49 years. Interventions All ED visits from 2010-2014 for which International Classification of Diseases, ninth revision codes for AUB were listed as the principal diagnosis were compared. Health insurance coverage, demographic factors, hospital characteristics, comorbid anemia, and comorbid bleeding disorders were explored. Main Outcome Measures Number of visits, ED disposition, blood transfusions, and billing for pelvic ultrasound. Results There were an estimated 262,939 ED visits nationally for women aged 10-49 years for AUB in 2014. Of these, 12.7% (33,511/262,939) were from adolescents aged 10-19 years. The number of adolescent visits with an AUB diagnosis declined by 11% from 2010-2014 (37,642 vs 33,511; P = .026), while visits by patients aged 20-49 did not change significantly (215,309 vs 229,428; P = .19). The number of adolescent visits for which Medicaid was the primary payer increased slightly, from 17,283 to 18,785, from 2010 to 2014 (P = .152), while the number using self-pay decreased from 8769 (23.4%) in 2010 to 5146 (15.4%) in 2014 (P Conclusion ED visits among adolescents with AUB decreased from 2010 to 2014. There was a sharp reduction in the number of visits funded by self-pay and a slight increase in visits funded by Medicaid.
