Evolution of Heart Failure-related Hospital Admissions and Mortality Rates: a 12-Year Analysis

A insuficiencia cardiaca (IC) e a via final de todas as cardiopatias. Com o avanco tecnologico, asobrevida do cardiopata vem aumentando. Paralelamente observa-se o aumento da incidencia da IC. Ha poucosdados em relacao a evolucao tecnologica e seu real impacto na mortalidade desses pacientes. Objetivo: Avaliar a evolucao dos indices de internacoes hospitalares em pacientes adultos com insuficiencia cardiaca, taxa de permanencia e mortalidade no Sistema Unico de Saude. Metodos: Os dados foram obtidos no DATASUS, referentes ao periodo de 2001 a 2012. Foram avaliados: a incidencia de internacoes hospitalares gerais e por IC, a media de permanencia, a mortalidade e o custo hospitalar, estratificados por sexo, faixa etaria e local de internacao hospitalar.Resultados: No periodo estudado ocorreram 91272037 internacoes hospitalares, sendo 3,96% por IC. Pacientes do sexo masculino corresponderam a 50,76%. O numero absoluto de internacoes por IC diminuiu de 379463 em 2001 para 240 280 em 2012. A media de permanencia global foi 5,8 dias em 2001 e 6,6 dias em 2012. A taxa de mortalidade esteve em ascensao, iniciando com 6,58% em 2001 e chegando a 9,5% em 2012 (aumento de 46,1%). O custo da AIH media aumentou de R$ 519,54 em 2001 para R$ 1209,56 em 2012 (aumento de 132,8%). Conclusao: Mesmo com a diminuicao das internacoes hospitalares, a IC e uma sindrome de elevado custo para o Sistema Unico de Saude, com elevados indices de mortalidade que paradoxalmente aumentaram ao longo do tempo apesar do avanco tecnologico ocorrido... Heart failure (HF) is the final common event of all cardiac diseases. Technological advances have allowed for significant improvement to survival rates in cardiac patients. Correspondingly, an increase in the HF incidence has been observed. Few dataare available on technological advances and their actual impact on the mortality rate of these patients. Objective: To assess the progress of hospital admission rates of adult patients with heart failure, average length of stay and mortality rate in the Brazilian SUS (Unified Health System). Methods: DATASUS data for the 2001-2012 period were obtained. An assessment was performed of data such as all-cause hospital admissions and heart failure-related admissions, average length of stay in hospital, mortality rate and hospital costs, after being stratified by sex, age and place of hospitalization. Results: Over the study period, there have been 91,272,037 hospital admissions, of which 3.96% were due to HF. Male patients accounted for 50.76%. The absolute number of HF-related hospital admissions decreased from 379,463, in 2001, to 240,280, in 2012. The average overall stay in hospital was 5.8 days, in 2001, and 6.6 days, in 2012. The mortality rate was on the rise, from 6.58%, in 2001, to 9.5%, in 2012 (a 46.1% increase). The average cost of AH increased from R$ 519.54, in 2001, to R$ 1,209.56, in 2012 (a 132.8% increase). Conclusion: Despite the decline in hospital admissions, HF is a highly costly syndrome for the Brazilian Unified Health System, with high mortality rates, which paradoxically increased over time, despite technological advances...
