Abstract
BACKGROUND: There is lack of evidence on the TB treatment outcomes of TB/HIV co-infected patients who received anti-TB treatment in Sidama region. In this study, we aimed to assess the treatment outcome of TB/HIV co-infected patients receiving care at Adare Hospital in Hawasa City, Sidama Region. METHODS: A cross sectional study based on retrospective data among TB/HIV co-infected cases was conducted at Adare Hospital. The unit TB registry and antiretroviral therapy (ART) registry were reviewed for the period between September 1, 2016 and August 31, 2022 to measure TB treatment outcomes. Target population for this study was all TB/HIV co-infected cases aged 15 years or more treated at Adare Hospital in the Hawassa City Administration. The data sources for this study were the unit TB register at the TB clinics, patient charts, and the ART register of the facility. Data were entered and analysed using the statistical package SPSS version 26. A summary descriptive analysis was calculated. Bivariable and multivariable analyses were performed to identify associations between variables. RESULTS: During the study period, 298 TB/HIV co-infected cases were treated for TB in the Hospital. Thirty three (11.1%), of the cases had an unfavourable TB treatment outcome. The risk of an unfavourable treatment outcome was over three times higher among re-treated TB cases than among the new TB cases (AOR = 3.3, 95% CI (1.4, 7.9)). The risk of death was higher among stage-IV HIV cases (AOR = 8.1, 95% CI (2.3, 28.9)), and among participants who used non-communicable diseases medications during the cohort period (AOR = 7.3, 95% CI (1.6, 33.6). CONCLUSION: TB treatment success rate among TB/HIV co-infected cases in the current study was comparable to many other reports. There are factors that contributed for unsuccessful TB treatment outcome. Cautious follow-up of cases and managing these factors could help in improving the TB treatment outcome.
