    Abstract:
    BACKGROUND: Acutely decompensated heart failure (HF) has become the leading cause of hospitalization for people aged 65 or older. Hospital length of stay (LOS) is a key determinant of higher hospitals costs. The aim of our study is to identify the admission characteristics that predict a longer LOS for elderly patients admitted for an acute exacerbation of HF. METHODS: We prospectively evaluated 324 patients (65 years of age or older), who were consecutively admitted for decompensated HF to a tertiary teaching hospital. Variables present at the time of emergency room evaluation that could predict a longer hospital LOS were determined by comparing the characteristics of patients hospitalized for less than 4 days with those of patients needing a longer stay. RESULTS: There were 191 women (59%) and 133 men in the study, with an average age of 78.6 years and a mean LOS of 7.1 days. Multivariate regression models identified two independent predictors of a hospital stay longer than four days: female gender (p=0.03, OR 1.645, 95% CI 1.047-2.584) and poorer NYHA functional class (p<0.01, OR 1.699, 95% CI 1.135-2.542). CONCLUSION: In elderly patients admitted for decompensated HF, the female gender and a worse functional class at the time of admission were associated with a longer subsequent LOS.
