Spatial Analysis of the Tuberculosis Cure in Primary Care in Rio de Janeiro, Brazil
Abstract Background: Tuberculosis (TB) presents a high burden of disease and is considered a global emergency by the World Health Organization (WHO), consisting of the most important cause of death from infectious disease in adults. It is related directly to access to health services and socioeconomic factors. Primary health care provides greater linking people to health services and greater medication adherence in some chronic diseases. Also, it provides supervised treatment and the search for more effective contacts. Objective: This paper aims to compare the tuberculosis cure among the areas covered and not covered by the family health teams from 2012 to 2014. Methods: A cross-sectional study was carried out in Rio de Janeiro. The variables were obtained from the Notifiable Diseases Information System for Tuberculosis (SINAN-TB) and the socioeconomic variables from the 2010 national census. The socioeconomic variables were selected from the multivariate analysis using principal factors analysis techniques. For the spatial analysis was used a generalized additive model (GAM). Results: Association was found between TB cure and education, alcoholism, contacts search, serology for HIV and the elderly. People with family health coverage between 35 and 41 months had 1,64 more chance of cure when compared to people without coverage (95% CI 1.07 to 2.51). Conclusion: From the spatial analysis, it was possible to identify areas with less chance of cure for tuberculosis in the municipality.
