INTRODUCTION We sought to evaluate the use of Papanicolaou samples as a screening tool for sexually transmitted infections (STIs). METHODS Retrospective chart review analyzing Papanicolaou samples for STI. Samples were processed and results compared to clinical data to assess this technique's viability. Cases and controls were matched by sample date. Characteristics of women with STI testing were compared in bivariate analyses. RESULTS We analyzed 50 STI-positive and 50 date-matched samples. Thirteen (26.0%) of the STI-positive patients were not screened at their visit. Women without STI screening were older (39.5 vs. 30.0 years, P = 0.001); non-Hispanic White (65.9% vs. 46.4%, P = 0.05); and married (60.0% vs. 26.9%, P = 0.005) than women with STI screening. Fifty-eight were offered and accepted STI testing at their visit; 37 samples were STI-positive: 17 (29.3%) Mycoplasma genitalium (Mgen), 10 (17.2%) chlamydia, 6 (10.3%) trichomoniasis, 1 (1.7%) gonorrhea, and 3 (5.2%) had two STIs. Among the 42 patients without STI testing, 12 (28.6%) had positive samples: 6 (14.3%) chlamydia, 5 (12.0%) Mgen, and 1 (2.4%) trichomoniasis. CONCLUSIONS Over one-quarter of STI-positive patients were not screened; though low-risk by current screening criteria, a significant number may harbor untreated STIs; using Papanicolaou samples may allow for increased screening in this population.
