title: The Relationship Between Nurse Staffing and 30-Day Readmission for Adults With Heart Failure.
abstract: OBJECTIVE
  The purpose of this study was to better understand the relationship between nurse staffing and 30-day excess readmission ratios for patients with heart failure in the top US adult cardiology and heart surgery hospitals.
  
  
  BACKGROUND
  Heart failure is the most common cause of hospitalization for patients older than 65 years and is the most frequent diagnosis associated with 30-day hospital readmission in the United States.
  
  
  METHODS
  A secondary data analysis was conducted using nurse staffing data from 661 cardiology and heart surgery hospitals from the 2013 US News & World Report "Best Hospitals" survey. These data were combined with excess readmission ratios from the Centers for Medicare & Medicaid Services Hospital Compare database from 2013. An independent-samples t test was used to compare staffing (low/high) and excess hospital readmissions rates.
  
  
  RESULTS
  A significant difference (P = .021) was found between the low nurse staffing group (n = 358) and the high nurse staffing group (n = 303). Hospitals with a lower nurse staffing index had a significantly higher excess readmission rate.
  
  
  CONCLUSIONS
  These data provide further support to the body of research showing a positive relationship between nurse staffing and positive outcomes.
