The study aimed to evaluate the quality of data refers to the address of the tuberculosis (TB) case notified to the Information System for Notifiable Diseases (SINAN), from 2005 to 2008, in the city of Rio de Janeiro. Was created an indicator from the ratio between the incidence rate of TB, calculated from the neighbourhood declared by the patient, and the incidence rate of the neighbourhood, obtained after georeferencing address the same subject, with a view to measure the possible impacts that inconsistencies in address may cause the calculation of health's indicators in the district level. Two techniques of georeferencing data were used from the home address. A correction in the address field which changed 27% of the records was performed. There was a difference in the outcome between the two methods georeferencing 64 and 69%. With the manual process was reached 89% location. From the indicator created, it is noted that only 28% of districts with a value between 0.85 and 1.15, considered as reasonable. The localization process can be faster and more efficient with greater awareness and training for professionals responsible and use of any official record of register streets. The differences in the indicator I can assist in decision making more correct decisions.
