Prevalence of Tuberculosis and Treatment Outcomes of Patients with Tuberculosis among Inmates in Debrebirhan Prison, North Shoa Ethiopia.

Background: Prevalence of tuberculosis in vulnerable groups such as prisoners is usually high, and the problem is worsened by poor treatment outcomes. In spite of this, there is limited information regarding tuberculosis in prisons of Ethiopia. Hence, this study was aimed to assess the prevalence of tuberculosis and treatment outcomes of patients with tuberculosis among inmates of Debrebirhan prison in North Shoa, Ethiopia.

Methods: A retrospective cross-sectional study was conducted among inmates of Debrebirhan prison. Data were collected by reviewing the medical charts and other records of prison inmates diagnosed and treated for tuberculosis between September 2010 and August 2015. Data were entered and analyzed using SPSS version 21.0.

Results: A total of 162 patients with tuberculosis were registered and treated at Debrebirhan prison health center within the five years study period. The overall average prevalence was found to be 32 per 1538 (2139 per 100,000) prison inmates. Regarding treatment outcome, 44(27.2%) were cured, 59(36.42%) completed treatment, 2(1.24%) were treatment failures, 6(3.72%) died and 51(31.5%) were not evaluated. The five year's treatment success rate was found to be 63.62%. Area of residence (AOR= 3.59; 95% CI: 1.44, 8.93), duration of imprisonment (AOR = 3.67; 95% CI: 1.53, 8.78) and history of tuberculosis were significantly associated with treatment outcome of tuberculosis.

Conclusion: This study showed high prevalence of tuberculosis in Debrebirhan prison. It also revealed that the treatment success rate of patients with tuberculosis was lower than the target set by World Health Organization.
