title: Worse Prognosis in Heart Failure Patients with 30-Day Readmission.
abstract: BACKGROUND
  Heart failure (HF) readmission results in substantial expenditure on HF management. This study aimed to evaluate the readmission rate, outcome, and predictors of HF readmission.
  
  
  METHODS
  Patients with reduced left ventricular ejection fraction (LVEF < 40%) who were admitted for acute decompensation of de novo HF were enrolled to analyze readmission rate, mortality and predictors of readmission.
  
  
  RESULTS
  A total of 433 de novo HF patients with LVEF < 40% were enrolled during the period August 2013 to December 2014. The in-hospital and 6-month mortality rates were 3.9% and 15.2%, respectively. In those patients surviving the index HF hospitalization, the 30-day and 6-month readmission rates were 10.9% and 27%, respectively. At the end of the 6-month follow-up, the readmission group had higher mortality than the non-readmission group (27.66% vs. 10.36%; p = 0.001). The survivors of the 30-day readmission had similar mortality rates at 6 months, regardless of the cause of readmission (cardiovascular vs. non-cardiovascular: 25% vs. 30.43%, p = 0.677). Among all the parameters, prescription of beta blockers independently reduced the risk of 30-day readmission (odds ratio 0.15; 95% confidence interval 0.02-0.99; p = 0.049).
  
  
  CONCLUSIONS
  Those HF patients who suffered from 30-day readmission had worse prognosis at the 6-month follow-up. Regardless of the readmission causes, the patients surviving the 30-day readmission had similar mortality rates at 6-month follow-up. These results underscored the importance of reducing readmission as a means to improve HF outcome.
