title: Reducing readmissions following paediatric cardiothoracic surgery: a quality improvement initiative.
abstract: BACKGROUND
  We have previously identified risk factors for readmission following congenital heart surgery - Hispanic ethnicity, failure to thrive, and original hospital stay more than 10 days. As part of a quality initiative, changes were made to the discharge process in hopes of reducing the impact. All discharges were carried out with an interpreter, medications were delivered to the hospital before discharge, and phone calls were made to families within 72 hours following discharge. We hypothesised that these changes would decrease readmissions.
  
  
  METHODS
  The current cohort of 635 patients underwent surgery in 2012. Demographic, preoperative, operative, and postoperative variables were evaluated. Univariate and multivariate risk factor analyses were performed. Comparisons were made between the initial (2009) and the current (2012) cohorts.
  
  
  RESULTS
  There were 86 readmissions of 77 patients during 2012. Multivariate risk factors for readmission were risk adjustment for congenital heart surgery score and initial hospital stay >10 days. In comparing 2009 with 2012, the overall readmission rate was similar (10 versus 12%, p=0.27). Although there were slight decreases in the 2012 readmissions for those patients with Hispanic ethnicity (18 versus 16%, p=0.79), failure to thrive (23 versus 17%, p=0.49), and initial hospital stay >10 days (22 versus 20%, p=0.63), they were not statistically significant.
  
  
  CONCLUSIONS
  Potential risk factors for readmission following paediatric cardiothoracic surgery have been identified. Although targeted modifications in discharge processes can be made, they may not reduce readmissions. Efforts should continue to identify modifiable factors that can reduce the negative impact of hospital readmissions.
