Profile of tuberculosis patients progressing to death, city of São Paulo, Brazil, 2002.

OBJECTIVE: To profile adult patients dying of tuberculosis in the city of São Paulo with respect to biological, environmental and institutional factors. METHODS: Descriptive study covering all tuberculosis deaths (N=416) among individuals aged over 15 years in 2002. Data were obtained from hospital records, the local Mortality Information System, Coroner's Service, and tuberculosis Surveillance System. The estimates of relative risk and 95% confidence intervals (95% CI) were based on the reference group, i.e., females aged 15 to 29 years, originally from the State of São Paulo (Brazil). A comparative analysis was conducted using Pearson's chi-square test and Fisher's exact test for categorical variables and Kruskal-Wallis test for continuous variables. RESULTS: Of all tuberculosis deaths identified, 78% had pulmonary form. Tuberculosis diagnosis was made after death in 30% and in primary health care units in 14%. Of them, 44% had not started treatment; 49% were not notified; and 76% were men. The median age was 51 years; 52% had up to four years of schooling; 4% were probably living in the streets. Mortality rate increased with age; it was 5.0/100,000 for the entire city, ranging between zero to 35 according to the district. Previous treatment was reported for 82 out of 232 patients, and of them, 41 defaulted treatment. Diabetes (16%), chronic obstructive pulmonary disease (19%), HIV infection (11%), smoking (71%), and alcohol abuse (64%) were also reported. CONCLUSIONS: Adult males over 50, migrants and living in lower Human Development Index districts were more likely to die of tuberculosis. Low schooling and comorbidities are relevant characteristics. Low involvement of primary care units in tuberculosis diagnosis and high underreporting of cases were also seen
