Paramedic crews in Nottinghamshire spent more time at emergency scenes, primarily when performing interventions for medical emergencies. This increased time also led to longer turnaround and out-of-service durations for ambulance services.

Area of Science:

  • Emergency medical services research
  • Ambulance operational efficiency
  • Paramedic practice analysis

Background:

  • Understanding emergency ambulance crew deployment and utilization is crucial for optimizing response times and resource allocation.
  • Paramedic roles have expanded, necessitating an evaluation of their impact on operational dynamics.

Purpose of the Study:

  • To analyze current patterns of emergency ambulance crew deployment and usage in Nottinghamshire.
  • To specifically examine crew status (technician vs. paramedic), patient case mix, interventions performed, and operational times.

Main Methods:

  • A retrospective analysis of 242 randomly selected emergency callouts in Nottinghamshire from September 1994.
  • Utilized routinely collected ambulance service despatch data and patient treatment forms.

  • Collected data included patient demographics, diagnostic groups, crew status, operational times, and paramedic interventions.

    • Main Results:

    • Paramedic crews were involved in 70% of callouts, performing extended skills in 18% of cases, mainly for medical emergencies.
    • Paramedic crews had significantly longer on-scene times (14.0 min vs. 11.5 min).
    • Paramedics performing interventions showed significantly longer on-scene, turnaround, and out-of-service times compared to those who did not.

    Conclusions:

    • Extended time spent by paramedics at emergency scenes is linked to performing interventions, not patient assessment for evacuation decisions.
    • Paramedic interventions were most frequently utilized in medical emergencies.
    • The performance of paramedic interventions contributed to increased turnaround and total out-of-service times for ambulance crews.
