Hospitalization, deaths, expenses respiratory diseases and its relationship with climate change in the municipality of San Carlos - SP, Brazil

Study design: Ecological time-series study Objectives: To describe respiratory disease (RD) hospitalizations, deaths, costs and verify their relations with climate change. Methods: Annual and monthly data were collected from hospital admission record (HAR) and deaths of the Department of the Unified Health System provided by the system of the SUS Hospital Information, in the period 2008 to 2012, which included the number of HAR, deaths and costs with RD, according to International Classification of Diseases, in São Carlos/SP, Brazil. In addition, we collected meteorological data (average maximum temperature, average minimum temperature and humidity relative air) through the National Institute of Meteorology (INMET) in the same period. Results: A total of 7.144 RD hospitalizations were authorized, and pneumonia was the most prevalent (59.93%). There was a decrease of HAR and public costs and increased total mortality rate RD (10.8%) from 2008 to 2012. The HAR had moderate (0.50- 0.69) and negative correlation with the average temperature compensated and maximum; and weak negative correlation with average temperature minimum. Mortality rate had a positive weak correlation (0.26-0.49) with average temperature compensated and maximum temperature. Costs had a negative weak correlation with average temperature compensated, maximum and minimum. Conclusion: RD responsible for the largest HAR values and deaths were pneumonia, COPD, acute bronchitis, acute bronchiolitis, asthma and chronic diseases of tonsils and adenoids. It was also observed that climate change were associated with HAR, mortality rate and health costs
