[Quality of care at a regional emergency medical system]

The Emergency Medical System (EMS) in the district of Florence is based upon the activity of 13 Emergency Mobile Unit (EMU). The activity of such a huge system is difficult to evaluate: we have concentrated our attention upon the diagnostic process assuming that "correct diagnosis = correct treatment = benefit for the patient". Then we compared diagnoses set on EMU to diagnoses made in hospitals, giving to each comparison a score from 1 to 5. In terms of quality the services of the EMS in Florence seem to be effective, since in 72% of cases the Hospital Emergency Department has confirmed the diagnoses achieved under emergency conditions, and in 12% only there has been remarkable difference. Comparing the diagnoses made on EMU to that at the hospital discharge, in two thirds of cases there is excellent correlation.
