Données épidémiologiques d'une cohorte de patients hospitalisés pour insuffisance cardiaque. Étude mono-centrique sur 3 ans. Comparaison avec les données régionales.

INTRODUCTION: Congestiveheart failure (CHF) is associated with prolonged and recurrent hospitalizations, the prognosis remains poor. The aim of this study was to collect epidemiologic data at admission and at six month follow-up in a cohort of patients with CHF admitted to a single center between 2017 and 2019 (Saint Joseph Hospital, HSJ) and to compare these data with regional data (Ile-de-France, IdF). METHODS: Local and regional data were provided by National Health Service, Regional Department of Ile de France(DRSM) using national data base. CHF in-hospital stay was defined by appropriate CIM 10 code reported on the final medical form. RESULTS: From 2017 to 2019, 1967 CHF in-hospital stays were collected, mean age of the population was 81.4 (=mean) ± 11.7 yearsIC95% [80.8; 81.9], mean length of stay was 8.6 ± 6.8 days IC95% [8.3; 8.9], in-hospital mortality was 5.3 %, 9.6% at 2nd month and 15.9% at 6th month. Readmission rate was 23.7%, time to readmission was 59.5 ± 47.5 days IC95% [57.4; 61.6]. IdF data collected 60973 CHF in-hospital stays at the same period. Compared to the IdF population, our population was older (81.4 ± 11.6 versus 80.4 ± 12.6 years, p = 0.001). Length of stay was shorter (8.6 ± 6.8 versus 11.3 ± 10.1 days p<0.001), in-hospital mortality was lower (5.3% versus 7.8% p < 0.001), 2nd month and 6th month mortality was lower (respectively 9.6% versus 14.2% and 15.9% versus 21.3%, p <0.001), home discharge rate was higher (66.9% versus 60.8%, p < 0.001) in the HSJ population. The proportion of patients included in PRADO-IC program (Programme d'aide au retour à domicile-Insuffisance Cardiaque, Returning home support program) was higher in SJ population (22.6% versus 8.8% p < 0.001). CONCLUSION: CHF admission involved elderly patients, the in-hospital and 6th month mortality is high, with early and frequent readmissions. Differences between HSJ and IdF populations may be explained by the heterogeneity of health care facilities, management facilities and organization of transition of care.
