title: Cost effectiveness analysis of neonatal extracorporeal membrane oxygenation based on four year results from the UK Collaborative ECMO Trial.
abstract: OBJECTIVE
  To assess the cost effectiveness of extracorporeal membrane oxygenation (ECMO) for mature newborn infants with severe respiratory failure over a four year time span.
  
  
  METHODS
  Cost effectiveness analysis based on a randomised controlled trial in which infants were individually allocated to ECMO (intervention) or conventional management (control) and then followed up to 4 years of age.
  
  
  METHODS
  Infants were recruited from 55 approved recruiting hospitals throughout the United Kingdom. Infants allocated to ECMO were transferred to one of five specialist regional centres. Follow up of surviving infants was performed in the community.
  
  
  METHODS
  A total of 185 mature (gestational age at birth >or= 35 weeks, birth weight >or= 2000 g) newborn infants with severe respiratory failure (oxygenation index >or= 40).
  
  
  METHODS
  Incremental cost per additional life year gained; incremental cost per additional disability-free life year gained.
  
  
  RESULTS
  Over four years, the policy of neonatal ECMO was effective at reducing known death or severe disability (relative risk = 0.64; 95% confidence interval 0.47 to 0.86; p = 0.004). After adjustment for censoring and discounting at 6%, the mean additional health service cost of neonatal ECMO was pound 17367 (95% confidence interval pound 12072 to pound 22224) per infant ( pound UK, 2001 prices). Over four years, the incremental cost of neonatal ECMO was pound 16707 ( pound 9828 to pound 37924) per life year gained and pound 24775 ( pound 13106 to pound 69690) per disability-free life year gained. These results remained robust after variations in the values of key variables performed as part of a sensitivity analysis.
  
  
  CONCLUSIONS
  The study provides rigorous evidence of the cost effectiveness of ECMO at four years for mature infants with severe respiratory failure.
