Synopsis

Directly observed therapy (DOT) was associated with a 40% lower odds of all-cause mortality among tuberculosis patients compared to self-administered therapy, after adjusting for sociodemographic and clinical factors (aOR 0.60). (3289585) As DOT coverage increased from 32.9% to 57.5% among TB patients in Taipei between 2006 and 2008, all-cause mortality decreased from 18.0% to 16.2%. (3289585) The protective effect of DOT on mortality was more apparent in patients with positive AFB smear status, with an adjusted odds ratio of 0.60 and a borderline significant interaction (P=0.071). (3289585) After adjusting for comorbidities, DOT remained associated with a 40% reduction in all-cause mortality compared to self-administered therapy (aOR 0.60). (3289585) Univariate analysis suggested DOT was associated with increased all-cause mortality, likely due to selection bias where sicker patients were more likely to receive DOT. (3289585)
