Short term prognosis of heart failure after first hospital admission

Death and unexpected readmission are frequent among heart failure patients. We aimed to assess 30-day readmission and mortality rate as well as to identify predictive factors for patients discharged from a first HF related hospital admission.

Retrospective, single-center, cohort study, using administrative data from a tertiary care hospital in Barcelona, Spain. Patients discharged alive from a first HF related admission from 2010 to 2014 were assessed for 30-day death, readmission and adverse outcome rate. A Linear Logistic Regression Model was fitted for each outcome. The set accounted for 3642 patients; 50.1% female and 49.9% male. Mean age was 76 years (SD=12). 30-Days rates were 9.2% for readmission, 5.6% for death and 13.8% for adverse outcome. Admission to an ED within 30 days was strongly linked to readmission (OR=6.97), death (OR=2.31) and adverse outcome (OR=8.55), as well as chronic kidney disease (OR=1.44/1.61/2.86 respectively). Discharge to a Long Stay Care (LSC) facility was linked to lower readmission and adverse event rates (OR=.57 and OR=.15).

Pre and post-index discharge use of health care resources is related to adverse outcome rates. Our findings point out the potential benefit for a more tailored approach in the management of HF patients.
