This research aimed to investigate the impact of opening a new ED within a health service district. The study involved linking ambulance, emergency department (ED) and hospital data from three EDs to better understand the patient journey and patient and health service outcomes when a new ED opens within the health service. The project aims were to:
1. Describe and compare patient and health service outcomes at three EDs before and 12 months after Robina ED opening;
2. Describe and compare outcomes for patients arriving to ED by ambulance based on whether off stretcher time is/is not delayed by >30 mins.
From this body of research, the team concluded that the whole patient journey needs to be included in future planning and in the design of health services. Strategic innovation needs careful analysis to ensure that the intervention does not shift the problem onto another part of the system. That is, to improve all service outcomes, when altering (increasing or decreasing) emergency department bed numbers, the whole healthcare system needs to be considered.
Specifically, the team found that by adding an additional emergency department within a health service area and increasing emergency department capacity from 81 to 122 beds:
1) Led to an increase (18%) in the total volume of emergency department presentations at a rate far greater than local population growth (3.1%): suggesting it either tapped into a previously unmet need within the local community or resulted in a shifting of activity from one sector to another;
2) Decreased the rate of deaths in emergency; but
3) Did not improve time-related service outcomes, such as ambulance offload time, time to see doctor and emergency department length of stay.
In further analysis, the team demonstrated that patient transport by ambulance to hospital did not guarantee timely access to medical care when there is a delay in ambulance offload time and blocked access to hospital inpatient beds. They concluded that along with older age, triage category (ATS 2, 3, 4) and offload times exceeding 30 min are easily identifiable predictors of an emergency department length of stay greater than four hours.
