Abstract 14776: Shorter Length of Stay in Hospital is not Associated with Higher Rates of 30 Days Readmissions Among Patients with Systolic Heart Failure in Minority Populations in an Inner City Hospital
Introduction: Nationwide, post discharge 30 days readmissions (readm) is high among patients with systolic heart failure (HF) and need to be reduced. Our objective was to assess length of stay and other predictors of 30 days readm.
Hypothesis: Shorter length of hospital stay is associated with higher 30 days readmissions among patients with systolic HF.
Methods: Retrospective analysis of consecutive 1,457 patients admitted from January 2010 to September 2011 with the diagnosis of acute decompensated CHF was done. Patients (n=829) with preserved LVEF (EF≥45%) and deceased (n=61) were excluded. Remaining (n=567) were divided into two groups: readmitted within 30 days (n=133) and those without (n=434). All the comparisons are between these two groups. First, patient demographics, co-morbid conditions, length of stay were analyzed using t-test and Chi-square test. Subsequently, we included all significant predictors on univariate analysis and performed Binomial Regression Analysis.
Results: Demographics and parameters studied are listed in Table Ia. Even though on univariate analysis shorter hospital length of stay was associated with significantly higher readm rates (p=0.04), upon binomial regression analysis (Table Ib), length of stay was not significantly different between these two groups (p=0.073). However, history of hypertension (p=0.046), ESRD (p=0.009), LVEF < 30% (p=<0.0001) and Hgb < 10 mg/dl (p=0.024) were significant predictors of 30 days readm.
Conclusions: In an inner city hospital with predominant minority populations among patients with systolic HF, shorter length of stay did not predict higher rates of 30 days readmissions. However, history of hypertension, ESRD, Hgb < 10 mg/dl and reduced LVEF were associated with higher 30 days readmissions.
