Emergency department throughput has become one of the clearest signals of how well an entire hospital is functioning. In November 2025, the Centers for Medicare and Medicaid Services finalized a new Emergency Care Access and Timeliness measure in its 2026 outpatient payment rule, putting boarding and ED flow on the record in a way they have never been before. The American College of Emergency Physicians reports that more than 90 percent of emergency departments routinely operate under crowded conditions, and roughly 66 percent of all hospital admissions are processed through the ED. When the front door slows down, everything behind it slows down too.
Why Throughput Is a Whole-Hospital Problem
The instinct is to treat throughput as an ED problem, but the data points somewhere else. Boarding, the practice of holding admitted patients in the ED until an inpatient bed opens, is driven by what happens upstream and downstream of the department itself. A patient cannot move to a bed that is still occupied, and a bed cannot open until the patient in it is discharged and physically on the way home. That makes throughput a whole-hospital flow question rather than a departmental one. It is also a safety question, since a 2025 study in the Journal of the American College of Emergency Physicians Open linked crowding and boarding to higher rates of departmental error.
How to Improve ED Throughput: A Step-by-Step Approach
The hospitals making real progress do not chase a single fix. They work a short, repeatable sequence that moves each patient from admission to an open bed, and they treat every step as part of the same flow.
- Start discharge planning on day one. Begin planning the discharge on the first day of the inpatient stay rather than the morning a patient is cleared to leave. Vizient leaders note that case management is often reactive when it needs to be proactive.
- Move routine discharges to the morning. Shift routine discharges earlier in the day so beds open during the highest-demand admission windows instead of the late-afternoon crush.
- Run daily multidisciplinary rounds. Bring physicians, nursing, case management, and social work together to align on a projected discharge date and organize the day around it.
- Remove the coordination bottlenecks. A 2025 study in Cureus found that discharge is frequently delayed not by clinical need but by fragmented coordination of imaging, consults, documentation, and transportation. Jason Harber of LeanTaaS notes that roughly 60 percent of hospital discharges are to home, the clearest opportunity to free inpatient capacity.
- Treat the ride home as part of the discharge plan. Arrange transportation the moment a discharge date is projected, not after the order is signed, so the last step in the chain never becomes the one that holds the bed.
The results are measurable. At Kaiser Permanente Northern California, targeted flow interventions cut average ED-to-floor wait times from 178 minutes to 110 minutes, a 38 percent reduction, and raised the share of patients admitted within an hour from 9 percent to 32 percent. Qventus, an AI capacity-management company led by Mudit Garg, reports the same pattern: client hospitals cut ED boarding by 10 to 20 percent after building early discharge planning into daily workflows.
The cost of leaving it unaddressed is just as concrete. In a 2025 report, the Florida Hospital Association documented more than 403,000 hospital bed-days lost to patients who were medically ready to leave but were waiting on post-acute placement or home care. Every one of those days is a bed unavailable to the next admission waiting in the ED.
Transportation: The Step That Turns a Discharge Order Into an Open Bed
Of all the levers above, transportation is the last one in the chain, the step that turns a discharge order into an open bed. Transportation gaps are well documented across the care continuum, and one national analysis found that 5.8 million Americans delayed medical care in a single year because they lacked a way to get there. The same gap reappears at discharge. When the order is written but no ride is confirmed, the patient stays, the bed stays full, and the delay travels back through the building to the patient still waiting on an ED gurney.
Dr. Noreen McDonald, PhD, of the University of North Carolina at Chapel Hill and a co-author of that analysis, sees coordination as the lever. “Studies in North Carolina demonstrate that coordination amongst medical and transportation providers is essential to improving patient experiences,” McDonald says. “Technology tools can be part of the solution to increase the needed coordination.”
Discharge is where that coordination gets tested. The care team knows when the bed will free up. The transportation provider knows what it takes to get the patient home safely and on time. Closing the distance between those two facts is what keeps the ride from becoming the delay.
Closing it is less about adding capacity than about treating the ride as a planned part of discharge. AHRQ’s Re-Engineered Discharge model organizes post-discharge needs, including transportation, in advance rather than at the last minute. A few patterns separate the hospitals that do this well:
- Transportation is arranged the moment a discharge date is projected, not after the order is signed, so the ride is never the last thing anyone thinks about.
- Booking pulls patient details straight from the EHR and generates the required medical-necessity paperwork automatically, so it takes seconds rather than a string of phone calls.
- The level of service, whether ambulatory, wheelchair, or stretcher, is matched to the patient up front, so trips are not failed and rebooked.
- Requests route to a tiered network of vetted providers, and each pickup is confirmed in real time, with status visible to the care team so a late ride surfaces before it costs a bed.
- On-time performance is tracked the way the hospital tracks any other throughput metric, so weak links stay visible and fixable.
Reclaiming Capacity in Full View of the Metrics
The path forward is clear and well within reach: treat the ride home as carefully as the hospital treats the bed. That is exactly the gap Ryde Central was built to close. By turning patient transportation from a series of phone calls into a coordinated, EHR-connected workflow, with the right vehicle, confirmed timing, real-time visibility, and performance data the care team can act on, Ryde Central helps hospitals make the last step of the patient journey as reliable as the first. And with CMS now measuring emergency care timeliness directly, that reliability is no longer just good practice but a measurable advantage: capacity reclaimed without new construction, in full view of the metrics that increasingly define hospital performance.
Frequently Asked Questions (FAQ)
In its 2026 outpatient payment rule, CMS finalized an Emergency Care Access and Timeliness measure that puts ED boarding and flow on the record for the first time. It makes throughput a tracked, reportable part of hospital performance.
A discharge order does not free a bed until the patient physically leaves, so a missing or delayed ride keeps the bed full. Arranging transportation early and confirming it in real time turns a discharge order into an open bed faster.
Start discharge planning on day one, move routine discharges to the morning, run daily multidisciplinary rounds around a projected discharge date, remove coordination bottlenecks, and arrange transportation as soon as that date is set. Each step opens beds sooner so patients waiting in the ED can move up.
Boarding is the practice of keeping admitted patients in the ED because no inpatient bed is available. It crowds the department, delays incoming patients, and has been linked to higher rates of error.
Most ED delays trace back to boarding, which holds admitted patients in the ED until an inpatient bed opens. Those beds free up only when patients elsewhere in the hospital are discharged and on their way home, so the bottleneck is hospital-wide.
Throughput is the speed and efficiency with which patients move through the ED, from arrival to admission or discharge. It is increasingly treated as a signal of how well the whole hospital is functioning, not just the ED.
