About this Presentation
This session demonstrates how the Theory of Constraints (TOC) was applied in a hospital emergency department to significantly reduce patient wait times and decrease risk of harm. The initiative also led to measurable improvements in staff morale and wellbeing. By addressing key bottlenecks and implementing focused improvements, the team created a sustainable model that enhanced both patient outcomes and workforce engagement.
What Will You Learn
To help you get the most value from this session, we’ve highlighted a few key points. These takeaways capture the main ideas and practical insights from the presentation, making it easier for you to review, reflect, and apply what you’ve learned.
Chaos isn’t the problem — misalignment is. The session reveals that emergency department overcrowding stems less from patient volume and more from systemic bottlenecks that block flow from triage through discharge.
You don’t fix ED wait times by adding staff alone. It shows how restructuring patient flow around actual constraint points (rather than resource counts) can dramatically reduce waiting and overcrowding without hiring more providers.
Visible signals beat invisible queues. The presentation teases how real-time flow indicators (not retrospective averages) let teams anticipate surges, match capacity to demand, and prevent backlog before it becomes crisis.
