Setting:
An urban TB diagnostic centre in Lusaka, Zambia.
Objective:
To re-evaluate treatment outcomes of all bacteriologically confirmed TB patients registered in 2018.
Design:
This was a retrospective cohort study on TB patients. Treatment outcomes of patients who were transferred out were retrieved.
Results:
A total of 182 patients were registered, 26 of whom had missing documents; these were excluded from the study. Of the remaining 156 patients who were reviewed, 86 (55.1%) were correctly evaluated by the centre, 35 (22.4%) were incorrectly evaluated and 35 (22.4%) were 'transferred out' (not evaluated). As a result of this review, the number of evaluated patients increased from 86 (55.1%) to 150 (96.2%). The cure and treatment success rates rose from 43.6% and 44.2%, respectively, to 57.7% and 73.1%, respectively. Of note, 14 of the 35 patients who were initially declared 'transferred out' did not actually reach their treatment facilities and ended up being lost to follow-up.
Conclusion:
This study shows that it is possible to evaluate almost all TB patients. Re-evaluation of treatment outcomes of TB patients revealed the problems in the TB services that need to be improved in the future.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
