The importance and safety of non-operative management (NOM) of Blunt Splenic Injury (BSI) has been established in children and adults over recent decades. However, studies have shown higher operation rates in adults. There is international evidence that when children are managed in adult centres, operation rates are higher while adolescents in paediatric centres, are operated on in line with paediatric guidelines. This difference between children and young adults, and the factors responsible, have not been examined in New South Wales (NSW).ObjectiveTo use NSW hospital and mortality data to compare the characteristics of BSI in patients aged 0-16 to those aged 17–25, and determine factors related to operative management (OM) and splenic salvage in each group.MethodsPatients age 0–25 between July 2000 and December 2011, with a diagnosis of BSI, were identified in the NSW Admitted Patient Data Collection, and linked to deaths data from Registry of Births Deaths and Marriages and Bureau of Statistics. Operation rate was compared between the two groups. Univariable analysis was used to determine factors associated with OM. Multivariable logistic regression with stepwise elimination was then performed to determine likelihood of OM according to age group, adjusting for potential confounders.Results1986 cases were identified, with 422 (21.2%) managed operatively – 101/907 children (11.1%) and321/1079 (29.7%)young adults(p<0.001). Of these, 59 (58%) children underwent splenectomy compared with 233 (73%) young adults (p<0.001). OM increased significantly after the age of 12 (p=0.03), and the percentage almost tripled in the teenage years, coinciding with a higher proportion admitted to adult centres. OM doubled again in young adults(p<0.001), all of whom were managed away from paediatric centres. On multivariable analysis, factors significantly associated with operation included age over 16 (OR 2.82, 95%CI 2.10-3.81), splenic injury severity, associated thoracic, liver, pancreatic and hollow viscus injury, and blood transfusion.ConclusionWhile Paediatric Surgeons have wholeheartedly adopted non-operative management, away from paediatric centres, it is possible children and young people in NSW are undergoing operation unnecessarily. Further evaluation of the surgeon attitudes and institutional factors involved in the management of injured children and young people within the broad NSW trauma system is required.
