title: Rotavirus, respiratory syncytial virus and non-rotaviral gastroenteritis analysis of hospital readmissions in England and Wales.
abstract: OBJECTIVE
  To quantify readmissions with infectious diseases and differences in readmission patterns.
  
  
  METHODS
  Using the CHKS database, children <5 years admitted to hospital in England and Wales, between 2000 and 2008, with rotavirus (RV), respiratory syncytial virus (RSV) or non-rotaviral gastroenteritis (NRV) were identified. All admissions within a 30-day prior period were similarly identified, and the proportion of readmissions was calculated.
  
  
  RESULTS
  There were 365,693 admissions for RV, RSV and NRV; 17.2% were readmissions. In 36% of cases, the cause of the prior admission was also RV, RSV or NRV, with 64% having a different prior diagnosis. The majority of readmissions were within 5 days of their prior admission, the majority of those with RV (n = 2,566/58.7%) within 3 days, NRV (n = 11 326/53.5%) within 4 days and RSV (n = 18 811/50.2%) within 9 days of prior discharge. Readmission for RV was associated with greater LOS than RSV (p < 0.001) and NRV (p < 0.001), while cost per admission was greater for RV compared to RSV (p < 0.001) and NRV (p < 0.001).
  
  
  CONCLUSIONS
  Thirty-six percent of readmissions indicated discharge without resolution from the first admission; nosocomial infection needs to be considered as a cause in the other. Although RSV represented the largest readmission group, higher costs and longer LOS were associated with RV.
