The aim of this study was to evaluate pain treatment with morphine administered by emergency medical service personnel (EMSP) to patients with chest pain and patients with pain in extremities because of trauma. This is a retrospective chart review of 2021 patients with chest pain and 887 patients with trauma. Pain was assessed using a 0-10 Numerical Rating Scale, and measured at the beginning and at the end of the ambulance care period.
