Purpose/Background: High resolution anoscopy (HRA) facilitates both diagnosis and treatment of Anal Intraepithelial Neoplasia (AIN) and has been shown to significantly reduce the risk of malignant progression. However, given the recurrent nature of anal dysplasia, close HRA surveillance is required for effective cancer prevention. Adherence to a surveillance protocol can be challenging as many patients affected by anal dysplasia belong to at-risk populations facing socioeconomic and cultural barriers. Lack of consistent follow-up can potentially compromise long-term outcomes for these high-risk populations. We aim to evaluate demographic factors associated with consistent follow-up (>=2 exams) among patients who have undergone HRA and to quantify disparities in follow-up.

Methods/Interventions: Adults (>=18 years) who presented for HRA between 2014-2024 at a single academic medical center were retrospectively reviewed. Sociodemographic variables included gender, race, sexual orientation (straight, bisexual, men who have sex with men (MSM), women who have sex with women (WSW)), presence of high-risk comorbidities (including HIV, presence of immunosuppression for autoimmune disease, cancer, or transplant, and history of gynecologic dysplasia/cancer), and area deprivation index (ADI). Relationships between follow-up amongst these sociodemographic factors were evaluated using Chi-squared or Fisher's Exact test as appropriate, logistic and Poisson regression analyses.

Results/Outcomes: A total of 723 people underwent HRA. Individuals who identified as MSM had a greater proportion of consistent follow-up (68.1% vs. 31.9%, p=0.02) compared to those of other sexual orientations. Women were 42.4% less likely to have consistent follow-up (OR 0.58, 95% CI [0.35-0.91]), which remained significant when controlling for insurance type and sexual orientation. Multivariate analysis revealed that women had 11% fewer follow-up exams than men (RR 0.89, 95% CI [0.79-1.00], p=0.003), which remained significant when controlling for sexual orientation, presence of high-risk comorbidities, and ADI.

Conclusion/Discussion: While correcting for multiple socioeconomic factors, women are less likely to adhere to appropriate follow-up recommendations for HRA. Targeted patient education, standardized follow-up protocols, and broader provider education could help improve adherence to surveillance across this population.
