Creating Synergy Between People and Process: Using Lean to Improve Emergency Department Efficiency and Patient Experience

Emergency departments (EDs) are a pivotal point of entry for patients requiring urgent medical attention, making ED efficiency a critical metric for hospitals. The Centers for Medicare & Medicaid Services (CMS) developed several performance measures to track how well hospitals manage patient flow, including the measure OP-18b: the median time from emergency department arrival to emergency department departure for discharged patients. This measure, while commonly used as a benchmark for time-based performance, is more than just a number. It reveals opportunities for improving patient flow, reducing bottlenecks, and enhancing overall patient experience through effective teamwork and process optimization.

By leveraging Lean Process Improvement principles, hospitals can reduce inefficiencies and enhance coordination between departments, allowing patients to move more seamlessly through the emergency department. But achieving these results requires more than just good processes—it requires a synergy between the people working at the front lines of patient care and the processes designed to streamline their work. This article explores how a thoughtful combination of “People” and “Process” can help hospitals not only meet the CMS OP-18b standard but also significantly improve the quality of care and the patient experience.
