Data on nonfatal firearm-related injuries. Commonly called the 'CDC Firearm Injury Surveillance Study'. Provides the basis for national estimates of nonfatal firearm-related injuries and nonfatal BB/pellet gun-related injuries treated in hospital emergency departments in the United States. Beginning in July 2000, the National Center for Injury Prevention and Control, in collaboration with the Consumer Product Safety Commission, expanded NEISS to collect data on all types and causes of injuries treated in a representative sample of hospitals. This system is called the 'NEISS All Injury Program (NEISS AIP)'. These data provide the basis for national estimates of all types of nonfatal injuries treated in hospital emergency departments in the United States.
