Factors associated with the over-treatment and under-treatment of gonorrhea and chlamydia in adolescents presenting to a public hospital emergency department

Abstract

The purpose of this study was to measure the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) and the rates and factors associated with their over-treatment (OT) and under-treatment (UT). A retrospective chart review was performed of patients aged 13-24 years who were screened for GC/CT in the emergency department (ED) of a public hospital. Descriptive statistics were obtained for all variables, and multivariate log binomial regression was performed to ascertain the factors associated with OT and UT. Seven hundred and ninety-seven adolescents and young adults were screened for GC/CT. The overall sexually transmitted infection (STI) positivity rate was 21.6%; 136 (21.6%) subjects were over-treated and 74 (43.4%) subjects were under-treated. Patients presenting with STI exposure or genito-urinary symptoms were more likely to be OT. Additionally, females aged 18-19 years or with a prior history of STIs were more likely to be OT. Females (83.6%) were more likely to be UT, while STI exposure, genito-urinary symptoms, and a prior history of STI were protective of UT . Adolescents and young adults screened for STIs have a high prevalence of GC/CT. A significant proportion of these patients end up over-treated and an even higher proportion are under-treated.
