Avaliação da atenção primária à saúde no estado de Minas Gerais, entre 2000 e 2011, utilizando o indicador internações por condições sensíveis à atenção primária

Abstract

The need to evaluate the health policies implemented for the structuring of primary care nationwide prompted the Ministry of Health to institutionalize assessment indicators already in use in several countries, including the indicator Hospitalizations for Primary Health Care Sensitive Conditions (HPHSC). Objective: To evaluate the primary care in the State of Minas Gerais, between 2000 and 2011, using the indicator HSPHC. Methods: This is an ecological study of Minas Gerais municipalities, using data from the Hospital Informations System, Ambulatory Information System, Computing Department of System Unique of Healph, and 2000- 2010 Census data from the Brazilian Institute of Geography and Statistics. The spatial dimension corresponded to the state of Minas Gerais and the temporal dimension was limited to the years between 2000 and 2011. Both were subjected to three selections, so that an analysis of HPHSC were performed under different views. Used the Minas Gerais municipalities as units of analysis, aggregating them by Regionals Health (RH). HPHSC rates were analyzed regarding to hospital stay, proportion of deaths and the relation with coverage by Family Health. The years between 2000 and 2010 were compared. Subsequently, the cities were analyzed in the three-years period 2009-2011, using the analysis of hospitalizations for infections of the kidneys and urinary tract sensitive to primary health (IKUT-PH) in individuals from 40 to 59 years, aggregated by RH, population size and coverage by family health. The IKUT-PH were analyzed by sex, regarding to hospital stay, number of deaths and costs of hospitalizations. Finally, were analyzed the most frequent causes of HPHSC by sex and age in the city of Juiz de Fora, comparing the four-years periods 2002-2005 and 2006-2009. For statistical analyzes we used the t test for paired data, ANOVA followed by post hoc Dunnett T3 and Scheffe test and correlation of Pearson. Results: Overall rates of HPHSC in the state declined between 2000 and 2010, but were not verified any correlations with the expansion on the Family Health Strategy. The RH showed that the highest rates were in Ubá and Leopoldina. The most frequent causes of hospitalization were heart failure and gastroenteritis. Some causes had higher rates, such as infections of the Kidney and Urinary Tract, making it the third most frequent cause in the state in 2010. The hospital stay and the proportion of deaths for HPHSC increased in the state. Juiz de Fora is highlighted as home to one of only two RH in which the HPHSC rate increased in the State. Conclusion: The governmental actions, such as the expansion of the Family Health

Strategy and the Health Regionalization, were not efective on decreasing the HPHSC in Minas Gerais. The characteristics of the municipalities affected in different ways in the behavior of rates, hospital stay and proportion of deaths by HPHSC. It is evidenced an increase in inequalities among the Regionals Health, what warns to the need of structuring the primary care in some regions of the State where the hospitalization due to potentially avoidable causes remains high.
