National trends in rate of patients hospitalized for heart failure and heart failure mortality in France, 2000-2012

Abstract

Aims: The objectives of this study were to describe annual trends in patients hospitalized for heart failure (HF) and HF-associated mortality rates in France between 2000 and 2012.

Methods and results: Hospital discharge data were extracted from the French National Hospitalization Database (PMSI). Mortality data were obtained from the French National Mortality Database. HF events constituting the underlying or associated cause of death were selected. Rates were age standardized using the 2010 European census population as the standard population. Time trends were tested using a Poisson regression model. In 2012, the overall age-standardized rate of patients hospitalized for HF was 246.2 per 100,000 inhabitants. The age-standardized rate of HF-associated mortality was 113.8 per 100,000 inhabitants in 2010. Hospitalized patient rates remained steady between 2002 and 2012, whereas mortality decreased by 3.3% annually from 2000 to 2010. Trends in hospitalized patients and mortality differed significantly between men and women, particularly among the 45- to 55- and 65- to 74-year-old age groups, with a smaller decrease observed in women.

Conclusion: Among men, a slight decrease in patients hospitalized for HF and a substantial reduction in mortality were observed. Among women, only a large decrease in HF mortality was observed. HF remains one of the leading causes of death and hospitalization in France, particularly in the elderly.
