Effectiveness of directly observed treatment short course (DOTS) on treatment of tuberculosis patients in public health facilities of Debre Tabor Town, Ethiopia: retrospective study

OBJECTIVE: The objective of this study is to assess effectiveness of directly observed treatment short course (DOTS) in treatment of tuberculosis (TB) patients in all public health facilities of Debre Tabor town, Ethiopia from January 2016 to December 2017. RESULT: Among 354 TB patients, 53.1% were males. Furthermore 22.6%, 40.4%, and 37% were smear positive pulmonary, smear negative pulmonary and extra pulmonary TB respectively. Study also revealed that TB–human immunodeficiency virus (HIV) co-infection and overall TB treatment success rate were 18.1% and 90.7% respectively. Regular weigh follow-up, sputum follow-up and HIV status were significantly associated with treatment success with P-value < 0.001, < 0.001 and 0.334 respectively. But TB treatment success weren’t associated with sex (P = 8.62), health facility type (P = 0.749) and TB type (P = 0.778). The study also showed that the overall TB treatment success rate was in line with World Health Organization (WHO) target on treatment success rate. Furthermore the study indicated higher TB–HIV co-infection and variations in conducting regular weight and sputum follow-up among HFs.
