Dynamic simulation environment differs from standard environments… Highly interactive with fast model building capabilities. On-the-fly changes– Modify, Analyze, Optimize the

model on the fly without the need to stop and restart the simulation

Connectivity to external data systems during the simulation run

Initial state loading based on current environment state. Dynamic model updates based on current constraints

and flows.

Reduced time for model building Enable simulation for everyone within the

organization Improve model accuracy Better optimization methods Improved analysis capability

Provide “life to the model” beyond the initial simulation effort.

Is the ED the real problem? Are patients waiting due to bed availability?

OR efficiency impact, patients waiting too long in PACU?

Forecasting with Real Data ?

2 examples often missed in the analysis process.

Looking in the wrong place?

Valid model representing the current state of the operation.

Data – actual patient information data (HIPPA Compliant)

Historical performance and data points. Staffing/provider constraint impact Ability to accurately forecast. Live model that can react to changes with

minimum interaction.

2 Methods to implement the simulation models Single model for Overall Hospital view. Multiple models connected through dynamic

interface.

Multiple models method provides Better model validation Faster delivery (multiple modelers) Ramped up implementation Distributed computing

Current state of bed allocation by Department Acuity Private/semi-private Other

Expected need – Short term – by Department Acuity Type Other factors

Bed Allocation Results

Cleaning schedule with priorities When should each bed be cleaned, grouped by

department Cleaning priority for each.

Discharge time impact on the schedule Effect of late discharge due to physician delays Schedule Adherence (Optimal vs current). Cause analysis of the delays.

Bed Allocation schedules

Better utilization of the OR Increased capacity Increased efficiency Reduced “Waiting for OR” time Improved staff efficiency

ED efficiency improvement Better predictability of the short term future

state improves staff and room scheduling.
