Abstract
Index case testing supports people living with HIV to facilitate voluntary testing for sexual partners and family members. Evidence on its uptake and determinants in Asella, Ethiopia, is limited. We conducted a facility-based analytical cross-sectional study among adults receiving antiretroviral therapy at three health facilities from 7 August to 30 September 2023. Systematic random sampling and face-to-face interviews were used. Logistic regression was performed using SPSS version 27. Of 422 sampled clients, 410 were analysed; 294/410 (71.7%, 95% CI 67.3–76.1) reported that at least one family member or sexual partner had been tested. In multivariable analysis, married participants (AOR 2.97, 95% CI 1.06–8.30), divorced or widowed participants (AOR 6.36, 95% CI 1.79–22.60), HIV-status disclosure (AOR 4.20, 95% CI 1.69–10.40), provider-led counselling and elicitation (AOR 4.96, 95% CI 2.20–11.10), and good HIV knowledge (AOR 3.00, 95% CI 1.50–5.71) were independently associated with testing. Uptake was substantial but incomplete. Strengthening provider-led counselling, supporting safe disclosure, and improving HIV-related knowledge may increase index case testing coverage.
