What happens to people diagnosed with tuberculosis? A population-based cohort

We examined different patient outcomes following diagnosis of tuberculosis (TB). Incident cases were reported to the enhanced surveillance system in the East of England, between 2000 and 2003. For the 575 cases reported in 2001 and 2002, outcomes were assessed 1 year after initiating treatment. The crude clinical incidence rate of TB was 6.0 cases/100 000 person-years (pyr) [95% confidence interval (CI) 5.7-6.4], highest in the 25-29 years age group (14.9, 95% CI 12.9-17.1 cases/100 000 pyr) and among Black Africans (328.6, 95% CI 286.9-374 cases/100 000 pyr). Patients born abroad were 2.35 (95% CI 1.03-5.32) times more likely to be lost to follow-up than those born in the United Kingdom. Age at diagnosis (OR 1.05, 95% CI 1.04-1.07) and pulmonary disease (OR 2.73, 95% CI 1.21-6.15) were independently associated with mortality. Elderly patients and those with pulmonary TB appear to have worse outcomes despite treatment. Foreign-born patients may need closer follow-up to ensure favourable outcomes. © 2007 Cambridge University Press.
