Study IV — System drivers of EMS response times
Study IV examines response time as a systems metric shaped by multiple interacting factors, including priority, workload/resource constraints,
temporal patterns, and geographic context.
Design
- Type: large-scale observational analysis of EMS operational data.
- Approach: explanatory analysis of response-time variability across context and priority strata.
Key contribution
The study treats response time as the result of system dynamics rather than a simple function of distance—supporting allocation and evaluation methods
that make variability and tail delays explicit.
