Peter Hill | EMS Allocation and Patient Safety Research

Research programme

Research on adaptive emergency medical services allocation

The programme examines EMS allocation as a safety-critical system problem: how to prioritise and distribute response capacity when patient need, geography, time, and uncertainty converge.

Research focus

Emergency medical services are expected to respond rapidly, safely, and equitably, yet they operate with limited units, incomplete early information, and changing demand. This research studies how allocation decisions are made, how response-time variability emerges, and how governance can make system strain and risk distribution more visible.

The patient safety net

Response capacity is treated as part of the patient safety net. The research asks how that safety net is maintained when demand exceeds immediately available resources.

Adaptive EMS allocation

Adaptive allocation concerns how systems reposition, reprioritise, and reassess ambulance resources as operational conditions change.

Dispatch under uncertainty

Emergency medical dispatch is analysed as real-time clinical and operational reasoning, including escalation, reassessment, and queue governance.

Response-time variability

Response time is interpreted as an emergent system measure shaped by call handling, travel time, workload, resource availability, priority, and geography.

Triage and clinical risk

Studies examine how dispatch suspicion, on-scene phenotype, triage labels, and patient factors relate to high-risk time-sensitive conditions.

Data-informed governance

The aim is to support responsible public-sector governance by making uncertainty, limitations, and distributional effects explicit.

The goal is not to replace professional judgement with automation. It is to improve system understanding, identify where risk accumulates, and support transparent decisions about scarce response capacity.
