How simulation is used in healthcare


Improve Emergency Department Performance

Crowding, delays, and diversions in the emergency department can contribute to quality and cost issues across an entire hospital system.

SIMUL8 Professional enables hospitals to improve patient flow, reduce walkouts, optimize resources and minimize costs.

What are the challenges of improving emergency departments?

Effective management of the emergency department (ED) is a key priority for health systems.

A national survey by the Institute of Medicine showed that 91% of EDs reported crowding as a problem with 40% indicating that it was a daily occurrence.

Healthcare providers recognize that long waits and delays aren’t just an isolated emergency department issue, but can become a hospital-wide problem.


Overcrowding in emergency departments can lead to:

  • Patient diversions to other hospitals
  • Patients being admitted to alternative units or ICUs
  • Patients leaving without treatment
  • Patients with acute illnesses experiencing delays in treatment
  • Excessive staff workloads, potentially leading to medical errors
  • Increased in-hospital mortality rates

Although healthcare providers understand these problems, with so many connected processes and elements involved, it can be difficult to plan and implement ED changes without risk to patient safety and satisfaction.

How can simulation help?

Experiment with changes in a digital, risk-free environment.

Research has provided lots of recommended approaches for improving ED throughput, reducing length of stay, mitigating readmissions and improving quality.

But how can you be sure which is the right approach for your department’s circumstances? With operational pressures and payment reform, each hospital is unique and needs planning and ideas specifically tailored to its local environment.

ED management is not a one-size-fits-all solution. There are many factors that can effect performance, including:

  • Patient behavior and health literacy
  • Patient demographics and the prevalence of chronic disease
  • Access to urgent and primary care
  • Practice and referral patterns of primary care providers
  • Utilization of social services and infrastructure
  • Clinical care protocols for acute conditions such as stroke, heart failure, and fractures
  • Available hospital beds and utilization
  • Mental health services in the local area

With many internal and external factors, as well as associated costs to consider, hospitals need the ability to test ideas in a safe environment.

This is why healthcare organizations rely on simulation to plan, test and implement ED improvements.

"We don’t want to go in to the ED and just make trial and error changes that could affect patient satisfaction and even safety if we’re not doing it in a thoughtful way."

Todd S. Roberts, System Director of Operations Improvement, Memorial Health System


“You can say, ‘What happens if I increase my person load coming to the ED by 20%?'. You can plug that into SIMUL8 and ask what that would do to the resources, or what the efficiency would of our staff would be.”

Raul Medina, Lean Six Sigma Black Belt and Lead Process Improvement Coordinator, Vidant Health

Why use simulation for emergency department improvements?

Benefit 1

Predict and manage demand surges and constraints

Utilize existing data sources and predictive analysis to accurately identify or forecast capacity constraints and surges in demand.

As simulation mirrors real processes in a visual way, you’ll easily see where queues and waiting times are happening – days, months or even years into the future.

Benefit 2

Test process changes in a safe, digital environment

Conduct powerful ‘what-if’ analysis to understand the impact of any changes in processes, resources, patient volumes and capacity on emergency department performance.

Simulation allows you to thoroughly test changes, without risk to patients and existing processes.

Benefit 3

Make cost-effective, evidence-based decisions

Compare improvement scenarios across waiting times, throughput, costs, and other important measures.

This allows decisions to go beyond opinions and expert recommendations, and instead be based on evidence and quantifiable results for your hospital’s own circumstances.

Johns Hopkins
Emergency department case study

Johns Hopkins reduced average wait times for ED psychology services from 61 to 16 minutes at its Howard County Hospital.

“With ongoing cost reductions and other restrictions within the healthcare environment, clearly our resources are getting to be very precious and scarce, so we need to use tools like SIMUL8 to make sure we are getting the highest performance we can out of the most reasonable amount of resources.”
