System Dynamics for Strategic Resource Planning at Watford Hospital
VisionThe vision of future work is that the modelling methodologies should be integrated into the everyday activities of the clinicians and staff that deal with changes to the emergency medical pathway,
after this is achieved…
simulating changes before implementing them should become a part of the Trust management processes.
System Dynamics for Strategic Resource Planning at Watford Hospital
Project Requirements – what to achieve?•1. A simulation environment to test policies, processes and decisions regarding the planning, deployment and maintenance of resources in emergency medical pathways at Watford Hospital.•2. A simulation toolkit enabling the sponsors to simulate decision making in emergency medical care.•3. A training environment for the internal use on A&E specific to the System Dynamics simulation tool, with supporting elective materials.•4. Use case for the Master Thesis of Goncalo Esteves.

Project Requirements – questions to be answered with the SD model:
1.What is the impact of increasing A&E flow direct to Medical Wards?
2.What is the impact of increasing the flow of patients from A&E to Ambulatory Care?
3.What happens if we have if we have more frail elderly patients going to ambulatory care, as opposed to being admitted?
4.When to change medical staffing arrangements?
5.Which are the most valuable staff arrangements to do?
6.What type of bed allocation is more effective?
7.What can cause the patient flow to stop?
8.What is the best use of beds over time?
9.What is the effect of having a GP in the initial assessment?
10. What is or what would be a single pathway of patients in the A&E?

Project Requirements – questions to be answered with the SD model:
1 – What is the impact of increasing A&EtoMedW
Bed numbers ( less beds available, more beds, less duration in stay, better care…)
2 – what is the impact of increasing the flow of patients from A&E to Ambulatory Care
Bed numbers ( less beds, more beds, less duration, better care)

Lessons Learned so far:
Access to data has many stepsModel validation to be done in terms of parts and not the wholeKeep modelling simple A4 – A3 pageImpact of factors outside our direct control – eg changes in staffing
