Purpose of Study: Acute decompensated heart failure (HF) is a major cause of hospital admissions in the US. Readmission within 30 days after an index HF hospitalization is common and portends a poor prognosis, regardless of ejection fraction (EF). The aim of this study was to determine the rate of readmission after an index HF admission and to identify risk factors associated with readmission in patients with both normal and reduced EF
Methods Used: Consenting patients with an index admission for HF at a single medical center were followed prospectively for 30 days. Data regarding demographics, risk factors and discharge plan was collected during the index admission and during any readmission to the center within 30 days. Patients who were not re-admitted within 30 days were contacted and interviewed via telephone for admissions elsewhere.
Summary of Results: 136 patients were enrolled in the study. 3 died during the index admission and were excluded from the analysis. 85 (63.9%) patients had a reduced EF (?50%) and 46 (34.6%) had a normal EF; 2 had no EF recorded and were excluded. Overall, 40 (30%) were readmitted within 30 days. There was no significant difference in readmission rates between patients with normal EF and patients with reduced EF (15/46 [33%] vs 25/85 [29%], p=0.43). Patients with a reduced EF were more likely to be readmitted if they had a history of …
