Objective. The study aims to determine the factors associated with unsuccessful treatment outcome among
patients who have undergone tuberculosis treatment.

Methods. An analytic cross-sectional study was employed through secondary data analysis of administrative
data collected by the National Tuberculosis Control Program from October 2015 to September 2016. Using
multiple logistic regression analysis, factors associated with unsuccessful treatment outcome were determined.

Results. Multiple logistic regression analysis revealed that belonging to age groups 25 to 34 (aOR=0.73; 95%CI
0.54-0.99) or 35 to 44 (aOR=0.75; 95%CI 0.56-0.99), being male (aOR=1.30; 95%CI 1.03-1.64), doing crafts
and related trades work (aOR=0.66; 95%CI 0.46-0.94), living in either a 4th class city (aOR=0.46; 95%CI
0.26-0.82), 1st class municipality (aOR=0.75; 95%CI 0.57-0.98), 4th class municipality (aOR=0.59; 95%CI
0.38-0.93), having a positive sputum smear result (aOR=1.60; 95%CI 1.29-2.00), having rifampicin-resistant/
multidrug-resistant tuberculosis (aOR=9.32; 95%CI 7.28-11.93), being a treatment after lost to follow-up case
(aOR=1.84; 95%CI 1.37-2.47) or a case with previously unknown treatment outcome (aOR=1.42; 95%CI 1.00-2.01)
were significant correlates of unsuccessful treatment outcome.

Conclusion. The study found that age, sex, occupation, residence, sputum smear results, drug resistance, and
history of previous treatment were associated with unsuccessful treatment outcome.
