Proportional Hazards Model on Attrition and its Predictors in Community Antiretroviral Refill Groups among ART Users in Eastern Ethiopia

Abstract

Background The HIV epidemic continues to be a major public health challenge worldwide, particularly in sub-Saharan African countries such as Ethiopia. Community-based antiretroviral refill groups are emerging as a patient-centered approach, but there is limited evidence. Therefore, this study aimed to assess attrition and predictors in community antiretroviral refill groups among ART users in Eastern Ethiopia. Methods Institutional-based retrospective cohort study was conducted. Systematic random sampling techniques were used. Data were collected via Kobo Collect and exported to Stata. Statistically significant effects were assumed for a P-value < 0.05 at a confidence interval of 95%. Results The incidence of attrition in community-based ART refill groups was 6.63 (95% CI: 5.78, 7.48) per 100 person-years. The median duration of months in CAGs from the start till the end of the follow-up period was 9 months (IQR = 24). Thus, recruitment level from health facilities, history of LTFU, and stage IV were statistically significant variables. Conclusion The findings of this study highlight the importance of improving the use of community antiretroviral groups in care. Healthcare programs can ultimately improve health outcomes for individuals living with HIV.
