To provide a “gold standard” for care of trauma patients, the American College of Surgeons Committee on Trauma developed Advanced Trauma Life Support (ATLS) in 1979. Prehospital Trauma Life Support (PHTLS) courses are based on ATLS and provide a prehospital trauma care philosophy that stresses the need to multisystem trauma as a unique entity with specific requirements. We participated in “provider courses” and “instructor courses” of PHTLS and were the first Japanese to be certified as PHTLS instructors. PHTLS was designed as a scenario-based program for prehospital care-providers of all levels. PHTLS courses are internationally recognized continuing education programs utilizing various teaching skills. This is the first report on PHTLS courses, which we believe are beneficial for prehospital emergency health care professionals and educators.
