title: Incidence of peptic ulcer bleeding in the US pediatric population.
abstract: OBJECTIVE
  The aim of the present study was to determine the incidence of peptic ulcer bleeding (PUB) in pediatric patients.
  
  
  METHODS
  A hospital inpatient database, Premier Perspective, and an insurance claims database, MarketScan, were analyzed to estimate upper and lower limits for the annual incidence of PUB in the US pediatric population.
  
  
  RESULTS
  Using data from the Premier Perspective database and database-specific projection methodology, the total number of cases of hospitalization of pediatric patients for PUB in the United States in 2008 was estimated to be between 378 and 652. This translated to an incidence of 0.5 to 0.9/100,000 individuals in the pediatric population. Using data from the MarketScan database, the incidence of PUB in the insured pediatric population was estimated to be 4.4/100,000 individuals. Overall, 17.4% of insured pediatric patients diagnosed as having any upper gastrointestinal ulcer in 2008 were reported to have developed PUB.
  
  
  CONCLUSIONS
  The estimated incidence of PUB in the US pediatric population in 2008 ranged from 0.5 to 4.4/100,000 individuals. The total number of cases of PUB in pediatric patients in the United States each year was thus estimated to be between 378 and 3250. Such estimates provide a likely lower and upper limit for the total number of cases of the condition annually.
