The National Pediatric Trauma Registry (NPTR) is a multi-institutional database designed to compile information concerning all aspects of pediatric trauma care. The registry is designed and operated in a manner that maximizes data accuracy and provides this information to all participating investigators. The growth of the database has allowed the NPTR to provide the first accurate epidemiologic description of pediatric trauma as a national disease, as well as to develop national norms for pediatric trauma care. The registry presently contains 10,177 patients, and is undergoing revisions (phase II) to allow a more focused evaluation of various aspects of the clinical care and rehabilitation of the pediatric trauma patient.
