Background: Tuberculosis and human immunodeficiency virus co-infection pose a major public health concern, particularly in developing countries. The survival and predictors of mortality were not sufficiently studied among TB-HIV co-infected patients in Ethiopia.
Objective: This study aimed to investigate the survival rate and predictors of mortality among TB-HIV co-infected patients during TB treatment at public health facilities in Bahir Dar, Northwest Ethiopia.
Methods: A retrospective follow-up study was conducted among 401 TB-HIV co-infected patients who were treated for tuberculosis between July 2018 and June 2022 at public health facilities in Bahir Dar city, Ethiopia. Data were collected using a structured checklist from patient charts. Data entry and analysis were done using EpiData 3.1 and Stata version 15, respectively. A Cox proportional Hazard regression model was used to identify predictors of mortality. Predictors with P < 0.05 in the multivariable regression were considered statistically significant.
Results: Among the 401 TB-HIV co-infected patients, 59 (14.7%) died during the follow-up period. Predictors like lower BMI (AHR = 3.00, 95% CI = 1.44, 6.28), extrapulmonary TB infection (AHR = 3.30, 95% CI = 1.50, 7.29), presence of opportunistic infection (AHR = 5.07, 95% CI = 2.55, 10.08), functional status (bedridden: AHR = 4.49, 95% CI = 1.63, 12.33), and adherence to TB treatment (fair = AHR = 2.74, 95% CI = 1.41, 7.20, and poor = AHR = 3.75, 95% CI = 1.52, 9.23) were associated with mortality.
Conclusion: Mortality among TB and HIV coinfected people was high at public health facilities in Bahir Dar city. This result suggested that in order to increase patient survival, it would be necessary to enhance nutritional status, increase adherence to TB treatment, and prevent opportunistic infections.
