Abstract

Objective: To determine the case-fatality rate (CFR) at the end of the intensive phase of tuberculosis (TB) treatment, and factors associated with fatality. Methods: TB patients diagnosed between 2006 and 2013 were followed-up during treatment. We computed the CFR at the end of the intensive phase of TB treatment, and the incidence of death per 100 person-days (pd) of follow-up. We performed survival analysis using the Kaplan-Meier method and Cox regression, and calculate hazard ratios (HR) and 95% confidence intervals (CI). Results: A total of 5,182 patients were included, of whom 180 (3.5%) died; 87 of these deaths (48.3%) occurred during the intensive phase of treatment, with a CFR of 1.7%. The incidence of death was 0.028/100 pd. The following factors were associated with death during the intensive phase: being >50 years (HR = 36.9;CI:4.8-283.4); being retired (HR = 2.4; CI:1.1-5.1); having visited the emergency department (HR = 3.1;CI:1.2-7.7); HIV infection (HR = 3.4;CI:1.6-7.2); initial standard treatment with 3 drugs (HR = 2.0;CI:1.2-3.3) or non-standard treatments (HR = 2.68;CI:1.36-5.25); comprehension difficulties (HR = 2.8; CI:1.3-6.1); and smear-positive sputum (HR = 2.3-CI:1.0-4.8). Conclusion: There is a non-negligible CFR during the intensive phase of TB, whose reduction should be prioritised. The CFR could be a useful indicator for evaluating TB programs.
