AbstractObjective: Professional guidelines and state law require screening for sexually transmitted infections (STI) during pregnancy. Our objective was to evaluate adherence to these recommendations. Methods: This is a retrospective cohort study of patients initiating prenatal care before 20 weeks' gestation. Demographic characteristics and STI screening were abstracted from prenatal records. Tests of interest included initial syphilis, human immunodeficiency virus (HIV), hepatitis B, chlamydia, and gonorrhea tests, as well as repeat (third trimester) syphilis and HIV tests. All patients were eligible for initial screening. Patients were eligible for analysis of whether they received adherent repeat third trimester screening for syphilis (mandated by state law) and HIV (institutional protocol) if they delivered at or after 32 weeks' gestation. Adherent screening was defined as performance of all recommended screening. Results: Of 2370 patients, 1816 (76.6%) received adherent initial STI screening and 181 (7.8% of 2308 patients who delivered at or after 32 weeks' gestation) received adherent repeat third trimester STI screening. After adjusting for covariates, private insurance (adjusted odds ratio [aOR] 1.45, confidence interval [95% CI] 1.12-1.95) was associated with adherent initial screening, whereas being non-Hispanic Black or Hispanic were associated with lower odds of adherent initial screening. Factors associated with adherent repeat third trimester STI screening were younger age (aOR 0.93, 95% CI 0.90-0.97) and non-Hispanic Black race (aOR 3.24, 95% CI 1.94-5.42). Those with private insurance (aOR 0.10, 95% CI 0.06-0.15) were less likely to receive adherent repeat third trimester screening. Conclusion: STI screening rates remain suboptimal. Multiple disparities exist in performance both of initial and repeat third trimester screening.
