Rethinking the ED walkout problem

Quantifying what is leaving the door

While each patient who leaves represents an immediate lost encounter, the financial impact can be felt beyond the ED. It extends to lost revenue, potential downstream utilization leakage, and increased clinical risk, particularly for higher-acuity patients who leave without evaluation or completion of care.

Over time, this cumulative leakage extends beyond the ED, contributing to declines in overall organizational performance and eroding trust and confidence in the health system. This is why Kaufman Hall, a Vizient company, has developed an innovative tool to measure the financial performance gap: the ED Throughput Opportunity Calculator, which translates walkout performance into an estimate of financial leakage and potential recovery opportunity.

The calculator uses brief inputs: annual ED volume, current LBTC rate, and hospital classification, with related performance assumptions, to establish a practical baseline for executive discussion. It is intentionally simplified and should not be interpreted as a precise forecast of lost downstream revenue. Its purpose is to create a credible starting point that enables leaders to recognize LBTC as both an access problem and a measurable source of financial leakage.

From awareness to execution

Quantifying the financial impact of walkouts establishes the size of the opportunity. The next step is to understand what drives LBTC and where the ED experience breaks down. That requires looking beyond the overall LBTC rate to identify precisely when and where patients leave, how patterns vary by time of day and day of week, and which operational constraints lead to walkouts.

The response should be tied to those specific drivers. Hospitals can use demand and arrival-pattern data to better align staffing, redesign front-end processes to accelerate initial assessment, establish rapid pathways for lower-acuity patients, and address the bottlenecks (e.g., diagnostic, consultation, disposition) that consume capacity.

Hospitals should consider a systemwide approach to improving ED throughput, making the reduction of ED boarding a shared organizational priority. This requires aligning leadership, incentives, and accountability across the ED, inpatient units, bed management, and discharge planning, so patients can move safely and efficiently through the hospital. Just as important, leaders should establish clear ownership and ongoing measurement of LBTC alongside wait times, boarding, and length of stay.

As ECAT brings greater visibility to these issues, organizations that can connect the data to specific operational actions will be better positioned to improve access, reduce walkouts, and sustain gains over time.
