Retrospective assessment of the status and determinants of tuberculosis treatment outcome among patients treated in government hospitals in North Shoa Administrative Zone, Amhara Regional State, Ethiopia.

Abstract

Background: One of the specific targets of Directly Observed Treatment, Short-course detailed in the updated Global Plan (2011-2015) was to achieve a treatment success rate of 87% by 2015. This strategy was introduced to Ethiopia in 1995 to reach full coverage in 2005; however, by 2009, treatment had not been as successful as expected.

Objective: This study was conducted to determine treatment success rate and identify risk factors for tuberculosis (TB) treatment outcomes in North Shoa Administrative Zone, Amhara Regional State, Ethiopia.

Methods: A retrospective cohort study was conducted on all TB patients (739) who registered for TB treatment from September 1, 2012 to August 31, 2014 at public hospitals in North Shoa Administrative Zone, Ethiopia. Data were gathered by using a pretested structured medical record checklist. Four data collectors and two supervisors were involved in gathering the data. The data were analyzed using descriptive statistics and logistic regression and were entered into Epi Info and analyzed by using the SPSS software package version 20.

Results: This study revealed that the TB treatment success rate was 86.1% (169 [22.9%] cured and 467 [63.2%] completed). In addition, 22 (3%) of the study participants defaulted their treatment of which 19 (86.4%) withdrew during the intensive phase. The multiple logistic regression model revealed that the study year of treatment, sputum smear positivity at the second-month follow-up, history of treatment default, and subsequent hospitalization were significantly associated with the TB treatment outcome.

Conclusion: The TB treatment success rate in the study area was low compared to that estimated by World Health Organization to achieve by 2015. Therefore, Federal Ministry of Health and Regional and Zonal Health Office have to strengthen the interventions on minimizing anti-TB treatment default rate through well-organized documentation, follow-up on TB patients, and awareness-creation programs.
