ABSTRACT
OBJECTIVE:
To calculate excess mortality in an annual cohort of tuberculosis patients and study the factors associated with death. MATERIAL ANDMETHOD:
Cases of tuberculosis reported in Catalonia (May 1996-April 1997). Patients were classified as completed treatment/cured (compliant), non-compliant, failures, transfers out and deaths. Excess mortality was defined as the ratio actual deaths/expected deaths (according to general mortality figures for Catalonia, May 1996-April 1997). Factors associated with death were determined by a comparative study of variables (demographic, substance abuse, comorbidity, tuberculosis-related disease) in deaths after diagnosis and survivors. Time from diagnosis to death was recorded.RESULTS:
Patients included 2,085. Patients classified as completed treatment/cured (compliant), 1,406 (67.43 %); noncompliant, 165 (7, 91%); failures, 5 (0.24%); transfers out, 25 (1.21%); deaths, 133 (6.38%), 28 of which occurred before diagnosis and 105 after diagnosis. Insufficient data in medical record for classification, 351 (16.83%) patients. Excess mortality 5.98 (95% CI 4.96-7.0). Factors associated with death treatment with non-standardized guidelines, 46%; OR 10.3 (6.2-17.4); HIV infection, 40%; OR 13.0 (6.6-25.8); age greater than 64 years, 40%; OR 14.6 (3.0-69.8); alcoholism, 25%; OR 2.0 (1.1-3.6); neoplasm, 16%; OR 3.9 (1.8-8.6; renal failure, 8%; OR 10.1 (3.1-32.3). The shortest time from diagnosis to death was in patients with only one risk factor, except for HIV infection, where the time passed was the longest observed.CONCLUSIONS:
We found substantial excess mortality in tuberculosis patients. Death was associated with the efficacy of treatment, HIV coinfection, advanced age, alcoholism and the coexistence of neoplasms or renal failure.
