ABSTRACT
Background Information. Monitoring outcome of tuberculosis treatment and understanding the specific reasons for unsuccessful treatment outcome are important in evaluating the effectiveness of tuberculosis control program. This study investigated tuberculosis treatment outcomes and predictors for unsuccessful treatment outcome in Ogbomoso town, Southwestern Nigeria. Methodology. Medical records of all tuberculosis patients registered from January 2008 to December 2011 in 5 Local Government areas, Ogbomoso, Southwestern Nigeria, were reviewed. Treatment outcome and tuberculosis type were categorized according to the national tuberculosis control guideline. Bivariate analysis was used to analyse the association between treatment outcome and potential predictor variables. Results. Out of the 965 total TB patients (579 males and 386 females) with mean age 42.4 ± 1.9 years, 866 (89.74%) were categorized as pulmonary tuberculosis and 109 (11.30%) as extrapulmonary tuberculosis. Treatment outcome among total 914 subjects was as follows: 304 (33.26%) patients got cured, 477 (52.19%) completed treatment, 87 (9.52%) died, 9 (0.98%) defaulted, and 1 (0.11%) failed treatment while 36 (3.94%) were transferred out. Higher treatment success rate was associated with those on Category 1 treatment (P < 0.05). Conclusion. The treatment success rate of tuberculosis patients was high (85.45%) compared to national target. However, certain proportion of patients died (9.52%) and defaulted (0.98%), which is a serious public health concern that needs to be addressed urgently.
