Abstract
Background: 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 data are 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.
Highlights
Heart failure (HF) is the final common event of all cardiac diseases
The purpose of this study is to assess the evolution of hospitalization rates of adult patients with heart failure, their average length of stay and mortality rate in the Brazilian SUS (Unified Health System)
The all-cause hospital admissions to heart failure-related hospital admissions ratio was reduced from 4.64%, in 2001, to 2.87%, in 2012 (a 38.0% decrease)
Summary
Heart failure is a syndrome whose prognosis is closely related to functional capacity, degree of systolic dysfunction and number of hospital admissions. 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). 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. 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
