Setting: Twenty-two first-line, two second-line and one tertiary health facility in Bishkek, the capital of Kyrgyzstan.

Objectives: Among migrants, a marginalized population at risk for acquiring and transmitting tuberculosis (TB), we determined the proportion with TB among all registered TB cases. For those registered at primary-level facilities, we then reported on their demographic and clinical profiles and TB treatment outcomes.

Design: This was a retrospective cohort analysis of 2012–2013 programme data.

Results: Of 2153 TB patients registered in all health facilities, 969 (45%) were migrants, of whom 454 were registered in first-line facilities. Of these, 27% were cross-border migrants, 50% had infectious TB and 12% had drug-resistant TB. Treatment success was 74% for new cases and 44% for retreatment TB (the World Health Organization target is 85%). Failure in new and retreatment TB patients was respectively 8% and 25%. Twenty-six individuals started on a first-line anti-tuberculosis regimen failed due to multidrug-resistant TB. Eight (25%) of 32 individuals on a retreatment TB regimen also failed. Loss to follow-up was 10% for new and 19% for retreatment TB.

Conclusion: Migrants constituted almost half of all TB patients, drug resistance is prevalent and treatment outcomes unsatisfactory. Fostering inter-country collaboration and prioritizing rapid TB diagnostics (Xpert®MTB/RIF) and innovative ways forward for improving treatment outcomes is urgent.
