•Most deaths from tuberculosis occur less than 60days after diagnosis.•Respiratory symptoms may have confused the diagnosis and contribute early TB death.•Different comorbidities and vulnerabilities are related with early or later TB death.•Almost half of TB deaths reported had one or more vulnerabilities. To know the profile of adults who died by tuberculosis as the main cause, the time interval between the diagnosis and death, associated comorbidities and vulnerabilities. Observational study of secondary data regarding deaths by tuberculosis that occurred in the State of Paraná, Brazil, from 2008 to 2015. A linkage between the databases of mortality and tuberculosis notification system was conducted for data enrichment. Frequency tables, Exact Fisher test and Z test have identified statistical associations. Linkage points out 12.1% (115/944) of under-reporting in the 944 deaths identified. Early deaths accounted for 74.6% (705/944). The male sex (75.8%) was associated with the early death group. Almost half of the deaths reported in notification system (414/829) had one or more vulnerabilities. Early death were associated with respiratory system diseases and symptoms (p=0.0001) and mental and behavioral disorders (p=0.0001). High number of early deaths due TB indicate the need to seek out the respiratory symptomatic and use faster diagnostic methods. Strategies for treatment adherence, adequate monitoring of comorbidities and multisectorial support may prevent early and late death. The presence of vulnerabilities indicates that efforts beyond the health sector are needed in order to eliminate tuberculosis as public health problem.
