Introduction: Health care workers (HCWs) are at high risk of latent tubercular infection (LTBI). In this study predictors of anti-tubercular treatment interruption in HCWs with LTBI are evaluated.
Methods: 1056 HCWs with LTBI were followed up to register adverse events and predictors of treatment interruption.
Results: 289 workers did not complete the treatment. Predictors of treatment interruption were adverse events (OR 1.47; 95CI% 1.07-2.03) and to be born in South-America (OR 1.55; 95CI% 1.06-2.26).
Conclusion: The higher risk in South-Americans supports the need of targeted formative interventions on these workers.
