Quality of primary health care: an analysis of avoidable hospitalizations in a Minas Gerais county, Brazil

Abstract

The aim of the study was to evaluate the quality of primary health care based on avoidable hospitalizations of men and women of all ages, from 2008 to 2012 in Alfenas County in the south of Minas Gerais state. This was an ecological study based on data from the Hospital Information System (HIS). The medical diagnoses selected for the study were pneumonia, diabetes mellitus and diseases of the circulatory system. There was a predominance of elderly males diagnosed with pneumonia, with an average hospital stay of five days. Admission rates for diseases of the circulatory system and diabetes mellitus tended to remain stable during the study period. While for pneumonia there was a tendency of growth that reached a plateau in early March 2009, bringing the average rate up from 2.01 to 3.51. The data suggest that primary health care is poorly organized to meet these diagnoses, particularly for pneumonia.
