Overarching aim A key aim of the QR Strategic Priorities Fund (QR SPF) is to support universities to link effectively with policy research priorities and opportunities, from the local to the international. In response to a policy question from our regional ambulance services we aimed to investigate the optimum configuration of single crewed rapid response vehicles (RRVs) vs double crewed ambulances (DCAs) to maximise ambulance response times.
  • Objectives
  • To explore crew mixes and costings in DCAs and RRVs (e.g. A4C banding on technicians and paramedics).
  • To assign unit costs to crew mixes in DCAs and RRVs.
  • To explore the probabilities of conveyance by category in selected high-volume calls for different ratios of RRVs to DCAs.
  • To estimate the cost of attendance and cost of conveyance for incidents first attended by an RRV and first attended by a DCA.
  • To explore other ways of modelling optimal configurations based on available data and existing literature.
Methods Decision analytic modelling study.
Outcomes Unit costs for RRVs and DCAs.

Graph of modelled cost versus percentage single crewed RRV.

Outputs
  • A set of recommendations and guides in the form of a policy brief and blog.
  • Reports and presentations to ambulance services.
  • Publication in peer reviewed journals.
  • Conference presentations.
  • Final report of the study.
Impact The study will seek to inform ambulance services about fleet configuration to maximise outcomes and efficiency.
