Abstract
A plan for quality measurement study of emergency medical services (EMS) in a region 200 x 35 miles with a population of about 500,000 is discussed. Specific questions to be answered are outlined and the sources of information for the study (the ambulance service, the hospitals, the corners' reports, and the provincial audit) are considered. A total of 100 motor vehicle accidents are to be observed and an appraisal is to be given to each incident of patient care.
