EMERGENCY MEDICAL SERVICES SYSTEM: SYSTEM DESCRIPTION AND OUTCOME STUDY PLANS
Eleven components of an emergency medical service (EMS) system are defined, and the results of system activity (patient outcomes, system products, and transfer outcomes) are described for each in a study of EMS care in Jacksonville Florida. Patient outcomes are brought about by a change within the patient (death, stabilization, etc.) ; system products result from a change within the system (no patient located, rescue run cancelled, etc.) ; transfer outcomes are results of system activity which transfers the actions of interest from one subsystem to another (call for help is dismissed or referred elsewhere) . Components or subsystems defined and discussed are emergency communications control, emergency transportation, other location, emergency department, patient activity, other help, fate, hospital, other hospital, other institutional care, and ambulatory. An overview diagram illustrates the complete set of systems and their reversible and non-reversible relationships. Detailed analyses of each system, along with characteristics of their interconnections, are illustrated and described in the appendices. Through mathematical modeling techniques, the following outcome measures are investigated in depth: effect of EMS on mortaility for acute myocardial infarction, unconsciousness, and accidents; effect of EMS on total incident cost; and effect of rate of pick-up and speed of arrival by rescue on infarction mortality in selected areas. Research design for these studies is described in detail. Portions of this document are not fully legible.
