Developing sentinel surveillance for chlamydia, gonorrhea, and trichomonas using test results from routine screening during pregnancy

OBJECTIVE: Our goal was to develop a sustainable electronic health record (EHR)-based approach to sexually transmitted infection (STI) surveillance in a sentinel population of pregnant persons. Study Design. We conducted a 1-year surveillance study of STIs in persons receiving at least 1 pregnancy related visit. Data were obtained using EHR analytic code. Subjects were categorized by whether they had a chlamydia test during pregnancy and by the STI test results, i.e. positive or negative. Bivariate analyses were performed to determine differences in persons screened and unscreened and persons who screened positive and negative for STIs.
