Background; Globally, the tuberculosis treatment success rate was worse for HIV-positive TB patients compared with HIV- negative TB patients. This study aimed at determining the impact of HIV-AIDS on and other associated factors with TB treatment outcomes.
Methods; A retrospective analysis five years of tuberculosis data from four public health facilities in Hossana Town was done. A total of 604 study participants were by systematic random sampling technique. Data were extracted from the database by using a structured checklist. Descriptive analysis, bivariate and multivariable analyses were done.
Result; A total of 604 TB patients were enrolled in this study. The overall treatment success rate was 90.1%. TB-HIV co-infected patients had a higher risk of the unsuccessful treatment outcome (ARR=2.7, 95%CI: 1.4-5.2). The risk of unsuccessful treatment outcome is also higher among rural residents (ARR 3.3, 95 CI 1.4-5.0, P-value 0.005), patients on re-treatment category (ARR 2.7, 95 CI 1.4-5.1, P-value 0.003), and with chronic disease (ARR 3.3, 95 CI 1.3-8.1, P-value 0.01).
Conclusion; Successful treatment outcome is lower among patients with HIV infection, rural residents, patients on re-treatment, and patients with chronic disease. Hence improve integration of the TB program with community health programs is required.
