    Study objective 

    Because overall EMS system response depends on ambulance availability, we conducted a prospective study of the EMS turnaround interval.

    This interval represents the time elapsed from ambulance arrival at the hospital until the ambulance reports back in service.


    An on-site observer, while monitoring EMS radio traffic, recorded the delivery and recovery activities of personnel from a large urban EMS system at a university hospital emergency department.

    System policy permitted a maximum turnaround interval of 30 minutes.

    Prospectively defined subintervals were analyzed.


    A convenience sample of 122 patient deliveries was collected.

    Observed and radio-reported times of arrival at the hospital differed by - 1'24 « to+11'08 ».

    In 18.9% of cases, arrival was reported on radio more than 5 minutes after the observed arrival.

    Time from arrival to removal of the patient from the ambulance averaged 59 « (range, 13 » to 2'53 « ), and time from patient removal to emergency department entry averaged 42 » (range, 10 « to 5'22 »). Time from ED entry to placement of the patient on an ED bed averaged 2'11 « (range, 33 » to 9'35 « ). Although the mean interval for the verbal report to ED staff was 33 » (range, 13 « to 2'53 »), it was 15 or less in 36% of cases.

    Writing the ambulance call report took an average of 17'12 « range, 5'20 »to 52'11 ). (...)
