How a high-volume community ED cut door-to-provider time from 47 to 7 minutes
Case study: A provider-in-triage model, supported by re-designed front-end roles and registration workflows, drove an 85% reduction in door-to-provider time, held left-without-treatment (LWOT) under 2%, and sustained 100% compliance on severe sepsis and stroke care—performance that has held steady through the COVID-19 pandemic, nurse staffing shortages, and a new ED build.

The challenge: A community ED outgrowing its workflow
A community medical center in the southern United States was serving a busy service area that depended on fast, reliable emergency care. As demand grew, outdated front-end processes and staffing constraints began to throttle throughput. Patients waited an average of 47 minutes from arrival to first clinician contact, beds were tied up by patients who could have moved to disposition earlier, and the rate of patients leaving without being seen began to climb. At the same time, the department needed to hold the line on the clinical quality measures that matter most—time-sensitive sepsis and stroke care.
These pressures are not unusual. As we discuss in our work on emergency and hospital medicine integration, emergency departments increasingly operate at the convergence of higher patient acuity, workforce shortages, and constrained bed capacity. Front-end design—how patients are screened, sorted, and routed in the first ten minutes—is the lever with the largest, fastest payback.
The strategy: Team triage with a re-engineered front end
Working in close partnership with the medical center’s leadership, the redesign centered on a team triage model. Rather than moving patients through registration, triage nursing, and a queue before reaching a clinician, a nurse practitioner or physician assistant was stationed adjacent to each of the two triage rooms to evaluate patients immediately on arrival.
Each element of the redesign was selected to remove a specific bottleneck:
- Screen-and-sort by a front-end clinician. The first clinician completes a brief screening and acuity sort. High-acuity patients are routed directly to an open bed, with diagnostics ordered before the patient leaves triage.
- Re-appropriated workspace as a flex evaluation room. When the main department is at capacity, the front-end clinician evaluates patients in a repurposed office space within the ED, preventing pile-up in the waiting area.
- A floating second front-end shift. Layered onto peak-volume hours, the second clinician supports the screener and the pediatric and mid-acute zones, absorbing surges without delaying lower-acuity care.
- A dedicated greeter role. A nursing-led greeter expedites patient flow, supports registration, and offloads administrative friction from the front-end clinical team.
- ID bracelet printers in each triage room. A small change that removed a recurring delay in the registration sequence.
These workflow changes were paired with the broader operational supports that come with an integrated emergency medicine partnership—leadership development for the medical director, structured performance reviews against a consistent dashboard, and recruiting support backed by national clinician staffing and recruiting infrastructure.
The impact: An 85% reduction sustained for years
Within the first year, average door-to-provider time fell from 47 minutes to seven minutes—an 85% reduction. The department then held that performance below 10 minutes for years afterward, including during a major construction project to build a new ED on the same campus. Even during the most acute phase of the COVID-19 pandemic, door-to-provider time rose to only 13 minutes.
LWOT—a leading indicator of access, patient experience, and revenue leakage—was held below 2% throughout. Compliance with the time-sensitive measures that matter most for outcomes was sustained at 100% for both severe sepsis management and stroke treatment, including through nurse staffing shortages that affected nearly every U.S. emergency department in the early 2020s.
The durability of the gains is, in many ways, the most important part of the story. A throughput improvement that holds only in calm conditions is fragile. The redesigned front end here weathered three sustained disruptions—a construction phase, a nationwide nursing shortage, and a global pandemic—with only modest performance variation. That stability reflects a structural change to how the department operates, not a temporary push.
Why it worked
Three principles, applied together, account for the durability of the results.
1. A clinician—not a queue—is the first patient contact
Moving a clinician to the front of the workflow compresses the diagnostic clock. Orders that would otherwise wait for a main-department physician are placed immediately, and the highest-acuity patients are identified before they ever leave the triage area.
2. Front-end roles are explicit and complementary
The screener, the floating second front-end clinician, and the greeter each have a defined scope. Roles are not improvised under load — they are designed for the load. When volume spikes, the floating shift activates rather than the team scrambling.
3. Small fixes to registration friction compound
ID-bracelet printers in each triage room and a greeter who carries the registration handoff are not glamorous changes. But every minute removed from the front-end sequence is a minute that does not accrue to a sepsis bundle clock, an LWOT decision, or a patient’s experience score.
Implications for emergency department leaders
The pattern described here is replicable, but the levers shift with department size, acuity mix, and physical layout. Three questions are worth asking before committing to a team triage redesign:
- Does the front-end clinician have a clear destination for high-acuity patients when beds are full? If not, the workflow stalls at the same point as before.
- How does registration friction impact door-to-provider time? Registration friction extends door-to-provider time by inserting administrative steps into the front-end sequence before clinical assessment begins, making its reduction one of the more accessible levers for improving early throughput.
- How is performance reviewed? Departments that sustain throughput gains tend to review a consistent set of metrics at a defined cadence with both operational and clinical leaders in the room.
These design questions overlap with the broader operating model SCP Health applies in our operational performance work across emergency medicine, hospital medicine, and critical care programs.
Frequently asked questions
What is door-to-provider time, and why does it matter?
Door-to-provider time is the interval between a patient’s arrival in the emergency department and their first evaluation by a qualified clinician (typically a physician, nurse practitioner, or physician assistant). It is closely tied to clinical quality (the sepsis and stroke bundle clocks start with arrival), patient experience, and the rate of patients who leave without being treated. Most high-performing emergency departments aim for sub-30-minute averages; programs using a team triage model can sustain single-digit averages.
What is a team triage model?
A team triage model stations a physician, nurse practitioner, or physician assistant at the front of the emergency department workflow. That clinician evaluates patients on arrival, performs an initial work-up, and orders diagnostics—often before the patient is moved to a treatment bed. The model compresses the diagnostic clock, identifies high-acuity patients sooner, and reduces the proportion of patients who leave without being seen.
How does the model hold up during a surge?
Surge performance depends on whether the redesign includes a flex pathway. In this case study, a floating second front-end clinician shift activated during peak volume, and a re-appropriated office space inside the ED served as a flex evaluation room when standard beds were full.
Does team triage increase total department staffing cost?
It typically reallocates existing front-end clinical hours rather than adding net new headcount. The floating shift is layered onto peak volume rather than running 24/7, and the greeter role is generally staffed from existing nursing or patient-access resources. Savings from reduced LWOT, faster bed turnover, and improved quality-measure performance commonly offset the redesign cost.
How long does it take to see results?
In this case study, door-to-provider time fell from 47 minutes to seven minutes within one year of partnership start. The largest gains usually appear in the first 90 to 180 days, once the front-end roles are stably staffed and the team has worked through several volume cycles. Sustaining the gains requires ongoing measurement and leadership cadence.
What clinical quality measures benefit most?
Time-sensitive measures—severe sepsis early management, stroke recognition and treatment, STEMI door-to-balloon—benefit most directly, because they depend on the diagnostic clock that team triage compresses. In this case study, the department sustained 95.5% compliance on severe sepsis management and 100% on stroke treatment.
