title: Unnotified deaths and hospital admissions for tuberculosis in the municipality of Rio de Janeiro.
abstract: OBJECTIVE
  To analyze underreporting of deaths and hospital admissions from tuberculosis to the Information System for Notifiable Diseases (SINAN).
  
  
  METHODS
  Cases with tuberculosis as basic or associated cause of death were selected from the Brazilian Mortality Information System (SIM) and hospital admissions for tuberculosis as main or secondary cause from the Hospital Information System of the Brazilian Unified Health System (SIH-SUS), for residents in the municipality of Rio de Janeiro in 2004. Probabilistic record linkage was carried out between the SIM and SIH-SUS databases and the SINAN for the years 2002 to 2004.
  
  
  RESULTS
  Out of the 542 deaths from tuberculosis in the period, 234 (43.2%) were not registered in the SINAN for the two previous years. As for the 1,079 admissions, 238 (22.1%) failed to be notified. Seventy-one deaths were related to these admissions: 47 were registered out of the SIH-SUS by death, 24 occurred after discharge and seven remained unnotified in the SINAN. The elderly were 1.6 times (95%CI 1.074;2.516) less likely to be notified than younger patients, and those with at least a college education were 3.6 times (95%CI 1.384;11.022) less likely to be notified than those with no formal education. Patients under 15 were 4.8 times (95%CI 2.757;8.452) less likely to be notified than those aged between 15 and 59 years. Some regional health administration divisions showed a percentage of unnotified deaths of over 50% and this percentage ranged from 37.8% to 12.7% for hospital admissions.
  
  
  CONCLUSIONS
  The data suggest problems in the detection of cases and point to obstacles in adequate and timely treatment, as well as to quality flaws in the information system, with differences among regions in the municipality.
