Abstract

BACKGROUND:

The case-fatality rate for tuberculosis (TB) remains high in China, whereas risk factors for deaths among TB cases are still unclear.

DESIGN:

This was a retrospective cohort study of all pulmonary TB patients registered in four districts of Shanghai from 2004 to 2008. Data were derived from the China National TB Surveillance System. A total of 4271 patients were followed up in communities. Data were analysed using Cox regression.

RESULTS:

The percentage of all-cause deaths in the study population was 15% 2-6 years after the most recent TB diagnosis. TB was responsible for only 17% of all deaths; male sex was significantly associated with all-cause deaths. After adjustment for sex, age and treatment history, four factors were significantly and independently associated with increased risk of death: psychopathy, chronic bronchitis, cancer and the presence of multiple diseases. TB was responsible for 7.2 potential years of life lost (PYLL); PYLL was higher in females (8.2) than males (5.3).

CONCLUSIONS:

TB remains a significant problem in urban China. Implementation of improved clinical management, prevention strategies and other public health programmes should target TB patients with chronic conditions, particularly those with multiple diseases.
