A Sequential Mixed-Methods Study of Factors Associated with Low High-Resolution Anoscopy Completion in Transgender Women with Abnormal Anal Cytology.

In a cohort of transgender women (TGW) with abnormal anal cytology (AAC) in Washington, DC, we determined the rates of and factors associated with completion of high-resolution anoscopy (HRA). This mixed-methods study used a sequential study design. In an academic-community clinic, we recruited TGW who provided blood samples, anal swabs for anal cytology, and completed surveys. For the quantitative phase of this study, we used χ2 test to compare factors associated with HRA completion among TGW with AAC. From that cohort, we used purposive sampling to recruit 16 TGW for qualitative interviews, based on their HRA completion status. We used thematic analysis to analyze the qualitative data. Of 75 TGW, 36 (48%) had AAC, 32 (43%) were referred to HRA, and 15 (20%) completed HRA. HRA completion was associated with being employed (75% vs. 25%; p = 0.01) in the quantitative phase, and low socioeconomic status (SES) was considered a barrier to completing HRA in the qualitative phase. HRA completion was associated with suppressed HIV (67% vs. 18%; p = 0.01) in the quantitative phase. In the qualitative phase, trans-affirming care, receptive anal sex, and engaging in sex work were identified as motivators to completing HRA. In a population of TGW, we found high rates of AAC and low rates of HRA completion. Interventions targeting this gap should address barriers associated with low SES and HIV viremia in TGW. Trans-affirming care and the impact on anal sexual practices should be used as motivators to engage TGW in anal cancer screening.
