Emergency Department Simulation

Case Study

Step 1

Data Gathering

Gather the data set needed for the simulation

Simcad Health®, offers an intuitive and interactive 3D simulation environment to improve, optimize and visualize healthcare systems. From ED and OR to hospital logistics and resource planning, Simcad Health® integrates with live and historical data to provide the most effective and interactive healthcare simulation system on the market today.

ED layout STEP

ED Layout - Patient Treatment Flow

Retrieve patient data, acuities and relevant treatment details from EMR. In the case where EMR Data is not available, Data flow collection is performed and imported into the model.

 

Provider Schedules

Define provider schedules and availability. Need to include shift duration and breaks.

ED 3d model

Patient Arrival Detail

Load currently used schedules from EMR (or other systems). The data will be used to validate and improve the OR.

External Department Availability

Identify the percent availability of external departments allocated to the ED. In the case where the data is not available, the model assumes maximum capacity available, allowing the simulation to generate the required levels for maximum ED Efficiency.

Step 2

Initial Model Skeleton

Basic model definition - ED Basic Identifies
  • Identify patient flow, travel constraints, hallways, and basic constraints.
  • Manage patient input properties based on the defined input data

Step 3

Capacity Analysis

Connecting the data and simulate for Capacity Analysis
ED Layout

Tag the CAD layout to auto-generate distances of travel for patient, providers and transport.

Patient Arrival History

Load the data arrival history data set and connect it to the model. Data can be retrieved dynamically from Excel, Databases, or EMR systems.

Treatment Cycle

Define the treatment cycle time per acuity and patient type. Waiting times Must not be imported into the model, but generated and optimized by Simcad® Health.

Wait times and delays need to be reduced and eliminated. This data is used for validation purposes only and MUST NOT be used as model inputs. The constraints are based on availability and capacity and NOT on time parameters to be optimized.

Providers’ Schedules and Availability

Shifts, cost, availability and other provider based constraints.

Capacity Planning

The model is now built with a validated flow and accurate behavior based on patient arrival data and length of stay validation. Current state capacity, constraints and bottleneck analyses allow for efficient capacity projections and planning.


Step 4

Expand Treatment Flows

Expand treatment flows & allocate providers

Generate distributions to analyze future state fluctuations.

** Distributions don’t have to fit a predefined known curve.
  • Arrival distributions (Based on Method)
  • Treatment time distribution based on Acuity and Gender
  • Triage Time distributions

Patients and Providers

Patients and Providers

Patients
  • Patients with different acuities require different treatment flows, and interact at varying intervals with the providers
  • Patients can change acuity during treatment. Acuity may increase or decrease based on assessment
Providers
  • Define different schedules, shifts and specialties
  • Enable provider travel based on distances for increase simulation accuracy
  • Define provider teams as needed based on acuity and patient properties

Step 5

Provider Analysis

Validation, Efficiency and Utilization

With the model validated, provider analysis (efficiency and utilization), along with external department impact are used to analyze the ED. By analyzing the internals of the ED along with all external factors, Length of Stay reduction and capacity increase can be achieved and sustained beyond the initial improvement effort.

Step 6

Expanding The Model - Next Steps

Based on improvement requirements, additional model details may be added...
  • Expand Treatment flows to incorporate external department interaction (X-Ray, MRI. Labs ... )
  • Expand the supporting departments, and exploring a more detailed impact on the model
