Treatment outcomes of tuberculosis patients under directly observed treatment short-course at Debre Tabor General Hospital, northwest Ethiopia: nine-years retrospective study.

backgroundData regarding tuberculosis (TB) treatment outcomes, proportion of TB/HIV co-infection and associated factors have been released at different TB treatment facilities in Ethiopia and elsewhere in the world as part of the auditing and surveillance service. However, these data are missing for the TB clinic offering directly observed treatment short-course (DOTs) at Debre Tabor General Hospital (DTGH).

methodsThe authors analysed the records of 985 TB patients registered at the DTGH from September 2008 to December 2016. Data on patients' sex, age, type of TB, and treatment outcomes were extracted from the TB treatment registration logbook. The treatment outcome of patients was categorized according to the National TB and Leprosy Control Program guidelines: cured, treatment completed, treatment failed, died, and not evaluated (transferred out and unknown cases).

resultsAround half of the registered patients were males (516, 52.4%). In terms of TB types, 381 (38.7%), 241 (24.5%), and 363 (36.9%) patients had smear-negative pulmonary TB, smear-positive pulmonary TB, and extra pulmonary TB, respectively. Six hundred and seventy-two patients (90.1%) had successful treatment outcomes (cured and treatment completed), while 74 patients (9.9%) had unsuccessful treatment outcomes (death and treatment failure).TB treatment outcome was not associated with age, sex, type and history of TB, or co-infection with HIV (P > 0.05). The proportion of TB/HIV co-infection was at 24.2%, and these were found to be significantly associated with the age groups of 25-34, 35-44 and ≥65 years:(aOR: 0.44; 95% CI: 0.25-0.8), (aOR: 0.39; 95% CI: 0.20-0.70), (aOR: 4.2; 95% CI: 1.30-12.9), respectively.

conclusionsThe proportion of patients with successful treatment outcomes was above the World Health Organization target set for Millennium Development Goal of 85% and in line with that of the global milestone target set at > 90% for 2025. Relatively higher proportions of transfer-out cases were recorded in the present study. Similarly, the proportion of TB/HIV co-infection cases was much higher than the national average of 8%.Thus, the health facility under study should develop strategies to record the final treatment outcome of transfer-out cases. In addition, strategies to reduce the burden of TB/HIV co-infection should be strengthened.
