Objective: Little is known about cervical cancer screening and results patterns among HIV-infected (HIV+) women in real-world healthcare settings. We characterized two periods of screening opportunity.

Design: Retrospective cohort.

Setting: US safety-net healthcare system in Dallas County, Texas.

Participants: We analyzed data from electronic medical records (EMR) of 1490 HIV+ women receiving care 2010–2014.

Main outcome measures: At baseline, we categorized a woman's Pap status 15 months prior to index date as under-screened (vs. screened), and cytology result (normal vs. abnormal). Then, we examined screening completion and results, and colposcopy uptake and results after an abnormal screen, in the subsequent 15-month period.

Results: More than half of women (56%) had no evidence of a Pap test (i.e. under-screened) at baseline. Under-screened women were more likely to be older (50–64 years), have diabetes, and unknown viral load; they were less likely to be Black, Hispanic, have Medicaid, recently pregnant, have a HIV clinic visit, or a CD4+ cell count at least 200 cells/μl. Nearly half of under-screened women (46%, n = 383) remained under-screened in the subsequent 15 months. Among women under-screened at baseline who later completed screening and follow-up during the study period, 21 high-grade dysplasia and three cancers were diagnosed. Overall, 40% of women did not receive colposcopy when needed, with most failures to follow-up occurring in women who were under-screened at baseline.

Conclusion: Most HIV+ women receiving care in a safety-net system did not receive sufficient screening for cervical cancer and remained at exceptionally high risk of developing high-grade dysplasia.
