title: Management of adult splenic injuries in Ontario: a population-based study.
abstract: OBJECTIVE
  To determine the population-based incidence of splenic injuries in the Province of Ontario, the proportion of splenic injuries treated by observation, splenectomy and splenorrhaphy, changes in management over time and the variation in management of splenic injuries among Ontario hospitals.
  
  
  METHODS
  A retrospective cohort study.
  
  
  METHODS
  All adults (older than 16 years) admitted with a diagnosis of splenic injury (clinical modification of the International Classification of Diseases, 9th revision) to acute care hospitals in Ontario between 1991 and 1994, identified from the Ontario Trauma Registry.
  
  
  RESULTS
  The incidence of splenic injury was 1.7 cases per 1000 trauma admissions per year. Patients with splenic injury were young (median age 32 years) and male (71%), and the death rate was 8%. Observation was the commonest method of treatment (69%), followed by splenectomy (28%) and splenorrhaphy (4%). The use of observation increased over the study period from 59% to 75% (p < 0.001). There was significant variation in the use of observation among hospitals (range 11% to 100%, p < 0.0001).
  
  
  CONCLUSIONS
  The majority of splenic injuries are managed by observation with an acceptable hospital death rate. The use of observation has increased over time, confirming the growing adoption of this management approach by most hospitals in the province when feasible. Splenorrhaphy was infrequently performed despite reports to the contrary from many centres in the United States. There was significant variation in splenic injury management, suggesting the need for further refinement and dissemination of practical guidelines for splenic salvage.
