Hospital emergency departments are being shaped by seven connected pressures: better outcomes, faster flow, expandable capacity, integrated technology, community access, disaster readiness, and the growth of freestanding emergency centers. The framework comes from a 2015 Building Design + Construction feature, so its examples and statistics describe the period around 2014–2015 rather than current national practice. Its value today is as a way to ask better planning questions: how should an ED protect privacy, move patients quickly, adapt rooms to changing acuity, and remain usable during a surge?
The seven factors combine clinical goals with architectural and construction decisions. None of the projects cited in the feature proves that one layout or technology works everywhere; each illustrates a trade-off that owners, clinicians, architects, engineers, and builders must examine for their own population and jurisdiction.

The feature grouped emerging emergency-department priorities into seven themes: outcomes and quality; Lean operations and patient flow; flexibility and expansion; technology integration; community outreach and access; catastrophic-event readiness; and freestanding emergency centers. They overlap in practice. For example, a universal treatment room can support faster flow, simplify surge operations, and reduce the need to reserve rooms for one specialty, while a freestanding site can improve geographic access without adding a complete acute-care hospital.
Because the source is historical, the numbers below should be read as period-specific evidence. They are not a current count of facilities, a current survey of emergency physicians, or a statement of present-day codes and reimbursement rules.

How did outcomes and quality begin to influence ED design?
In the feature’s 2015 context, concern about quality, waiting time, privacy, and infection control was pushing ED planning beyond simply adding more treatment bays. The article linked this shift to the Affordable Care Act’s then-relevant value-based payment discussion, but that policy context should not be assumed to operate identically today.
Private treatment rooms were one visible response. Higher-acuity patients may need confidential conversations, family communication, isolation precautions, and procedures that are difficult to manage in an open bay. The source cited Yuma Regional Medical Center’s planned 69-room ED, with all but four rooms private, as an example of that design direction. It is a project detail reported by the 2015 feature, not a universal prescription or a present-day benchmark.

Andrew Quirk, National Director of the Healthcare Center of Excellence at Skanska USA Building, summarized the period’s logic: “If an ED is going to be reimbursed on the quality of care, rather than volume, wait times have to be reduced and outcomes have to be improved.” The quote captures a design question that remains useful even when payment models change: which physical decisions measurably support safe, timely care, and which merely add floor area?
How can Lean methods improve emergency-department flow?
Lean methods treat patient movement, information, rooms, staff time, and equipment as one operating system. The feature describes observation studies, operational-data analysis, and simulation as ways to find delays before finalizing a building. It also presents split-flow rapid medical evaluation: patients with higher-acuity needs go to regular treatment rooms, while lower-acuity cases use a fast-track or rapid-evaluation area.
Marvina Williams, RN, Healthcare Clinical Operations Expert at Perkins+Will, described the intent this way: “Lean is a tool to help the ED reduce lengths of stay, improve the quality of work, lower costs, and improve patient and staff satisfaction.” The claim is about Lean’s purpose, not proof that every Lean project delivers each result.
Simulation can challenge an early room-count assumption. In the feature, Williams said a study’s simulation suggested a planned ED was larger than necessary and identified potential room reductions and savings. That example shows why owners should model arrival patterns, acuity, staffing, diagnostic turnaround, and discharge or admission paths together rather than size rooms from peak historical census alone.

The article also names MidState Medical Center’s Rapid Medical Evaluation module as reducing wait times, but gives no quantified before-and-after result. A project team should therefore define its own measures—time to clinician, time to disposition, left-without-being-seen rate, room turnover, and staff travel—before claiming improvement.
How does flexible capacity change the treatment-room layout?
Flexibility means a room can be used for different acuity levels and specialties, and that the department can add capacity without rebuilding its core circulation. HKS designers described a linear arrangement with a staff work area between two rows of treatment rooms, a configuration they said could allow incremental extension as demand grows.
Mercy Health’s Patti Meszaros described a move away from assigning every room to one specialty: “Now we’ve become far more flexible with our treatment points. One exam room treats all.” Universal or acuity-adaptable rooms can improve utilization when demand shifts between medical, trauma, behavioral-health, and observation cases. They may also require more deliberate equipment standardization, storage, infection-control procedures, and staff training.
The trade-off is not simply more rooms versus fewer rooms. Planners must examine visibility from staff workstations, walking distance, noise, family privacy, emergency access, the location of imaging and laboratories, and whether an expansion can preserve circulation and utilities. The feature offers no comparative measurements proving that one layout outperforms another, so those decisions belong in local simulation and operational review.
Why is technology being brought closer to the patient?
Technology integration in the feature means placing useful information, testing, communication, and entertainment where care occurs rather than treating the ED as a series of disconnected rooms. Mik Pietrzak, MD, Director of Strategy and Technology at MedStar Institute for Innovation, stated: “The outcomes of many time-sensitive health conditions, such as heart attacks, trauma, and stroke, are highly dependent on the speed of treatment.”
The article gives portable point-of-care equipment as one response. It names Abbott Point of Care’s i-STAT handheld blood-testing system and describes it as providing laboratory-quality results in less space than a traditional ED laboratory. That is an example from the 2015 article, not a current product recommendation or a claim that every hospital uses it. Any present procurement decision needs current clinical-validation, cybersecurity, maintenance, and regulatory review.

Other examples include patient-facing televisions, Wi-Fi-enabled tablets, and videoconferencing. These can support communication and patient experience, but they introduce infrastructure requirements: wireless coverage through clinical and isolation spaces, device-cleaning processes, charging and storage, accessibility, privacy controls, and integration with the electronic health record. Technology should be selected after the workflow is defined; otherwise, devices can add clutter without removing a bottleneck.
How can community outreach affect emergency-department planning?
Community outreach is both an access strategy and a design issue. The feature describes hospitals responding to retail clinics and other new providers by making the ED more welcoming, improving signage and marketing, and reducing the intimidation associated with a chaotic waiting room.
SSM Health Care’s online ED-registration system illustrates a targeted access model. The feature reported that it covered seven hospitals, that about 40% of visits involved non-life-threatening conditions, and that the system registered about 10% of annual ED visits. Those figures describe SSM’s reported experience at the time; they are not current operating statistics or evidence that online registration is appropriate for every patient group.
Digital registration must never delay emergency assessment. A safe design separates self-service or scheduled-arrival functions from immediate triage, provides alternatives for people without smartphones or reliable internet, and clearly warns users when symptoms require calling emergency services. Wayfinding, parking, public-transit access, lighting, family seating, language support, and behavioral-health safety are physical parts of the same access question.
What does catastrophic-event readiness require in an ED?
Routine efficiency is not enough when an ED faces a mass-casualty incident, disaster, terrorist attack, or infectious-disease outbreak. The feature’s “all-risk-ready” concept focused on preserving treatment capacity while controlling contamination and separating incompatible flows.
HKS’s concept included separate entry portals or chambers for screening and possible decontamination, controlled airflow, surface treatments, and deliberate placement of high-touch items to make cleaning easier. These are design concepts reported by interviewees, not current codes or validated universal recommendations. Owners must reconcile them with applicable public-health guidance, fire and life-safety requirements, engineering standards, and the hospital’s emergency-management plan.

Capacity is a central resilience test. Jim Lennon, AIA, ACHA, LEED AP, an Associate Principal at HKS, put it plainly: “The key is not to lose capacity during event-based conditions, when you actually need to increase capacity.” That means identifying spaces that can be converted, locating utilities and medical gases where expansion is feasible, protecting staff circulation, and planning how supplies, waste, security, and family reunification will work during an incident.
Why did freestanding emergency centers expand the delivery model?
Freestanding emergency centers place 24/7 emergency services outside a hospital campus. The 2015 feature said more than 400 dotted the United States at publication and described them as state-licensed facilities with on-site emergency physicians and round-the-clock laboratory and imaging capabilities. That count and description belong to the article’s publication era; licensing, staffing, reimbursement, and required services vary by jurisdiction and must be checked against current rules.
The feature distinguishes freestanding EDs from urgent-care clinics and presents them as a way to extend a health system’s geographic reach, including suburban, rural, and urban locations, without constructing a full acute-care hospital. Lenox Hill HealthPlex in Manhattan was cited as having treated more than 10,000 patients in its first five months and exceeding the 90th percentile in Press Ganey patient-satisfaction surveys, according to the feature. Alex Hellinger, the center’s Executive Director, said: “It’s not the chaotic scene that you see in most EDs.” These are historical facility claims, not a current performance comparison.
Construction strategy can be part of the business case. The article describes prefabrication, including offsite assembly of overhead mechanical, electrical, and plumbing racks at Rookwood Medical Center. Andrew Quirk attributed schedule, safety, quality, cost, and waste benefits to prefabrication, but the feature did not provide quantified comparative results. A project team should test those expected benefits against transport logistics, crane access, inspection requirements, commissioning, and the local labor market.

How should owners compare ED design options?
No single feature in the 2015 framework is automatically best. A decision matrix should connect each option to the population, clinical model, site, and capital plan.
| Decision area | Questions to answer | Risks to examine |
|---|---|---|
| Patient acuity and privacy | Which patients need private rooms, isolation capability, or family space? | Higher construction and cleaning requirements; inadequate privacy if rooms are over-open. |
| Flow and time to evaluation | Can triage, rapid evaluation, diagnostics, treatment, and disposition occur without crossing paths? | Fast-track areas that are separated from needed staff or diagnostic resources. |
| Expandable capacity | Can rooms, utilities, and circulation be added or repurposed in stages? | Expansion that consumes staff visibility or creates long travel distances. |
| Technology | Will bedside devices, wireless systems, and telehealth remove a documented delay? | Cybersecurity, cleaning, charging, interoperability, and maintenance burdens. |
| Surge and infection control | Where can screening, decontamination, isolation, and overflow occur? | Loss of routine capacity or unsafe mixing of clean and contaminated flows. |
| Access and location | Does the site serve the target population and connect to transport and referral networks? | Confusion with urgent care, limited access for people without digital tools, or insufficient backup services. |
| Capital and construction | What are the schedule, phasing, prefabrication, and operating-cost implications? | Unquantified savings assumptions, commissioning problems, or inflexible infrastructure. |
Use operational data and simulation to test the matrix. The source feature supports asking these questions, but it does not supply a universal scoring system or a present-day benchmark.

What should a practical planning process look like?
- Define the service model. Document arrival volumes, acuity mix, behavioral-health demand, observation care, trauma capability, diagnostic services, and referral destinations.
- Map current and desired flow. Follow patients, staff, supplies, waste, families, and emergency vehicles. Mark every handoff and queue.
- Model ordinary and extreme conditions. Test daily peaks, seasonal variation, simultaneous critical arrivals, infectious-disease screening, and mass-casualty conversion.
- Compare room and circulation concepts. Evaluate private rooms, universal rooms, split flow, linear expansion, staff visibility, travel distance, and clean/dirty separation.
- Specify technology by use case. Identify the clinical decision or communication step each device supports, then validate infrastructure, privacy, maintenance, and training needs.
- Verify jurisdictional requirements. Confirm current licensing, building, fire, accessibility, infection-control, imaging, laboratory, and emergency-management requirements with the appropriate authorities.
- Set measures before opening. Establish definitions and baselines for time to clinician, length of stay, left-without-being-seen, diagnostic turnaround, room utilization, patient experience, and surge conversion.
What is the lasting lesson from the seven factors?
The framework’s enduring message is that ED design is an operating decision expressed in concrete, steel, utilities, rooms, technology, and location. Private rooms address privacy and infection concerns; Lean analysis challenges waste; adaptable rooms protect utilization; bedside technology can shorten time-sensitive steps; outreach improves access; resilient layouts preserve capacity during emergencies; and freestanding centers move emergency care closer to some communities.
The evidence in the feature is a set of named projects, professional observations, and period statistics—not a current national survey. Treat each example as a prompt for local data, simulation, clinical governance, and jurisdiction-specific verification. That discipline is what turns an attractive concept into a department that can work on an ordinary shift and still function when demand suddenly rises.

Are freestanding emergency centers the same as urgent-care clinics?
No. The 2015 feature describes freestanding EDs as 24/7, state-licensed emergency facilities with on-site emergency physicians and continuous laboratory and imaging capability, while urgent-care services generally follow a different scope and regulatory model. Exact requirements differ by state, so patients and planners should verify the facility’s current license and services.
What data should a hospital collect before expanding its emergency department?
At minimum, separate arrivals by acuity and arrival mode, then track time to clinician, diagnostic turnaround, length of stay, disposition, left-without-being-seen, room utilization, and staffing by interval. Include behavioral-health, observation, infection-control, and surge events so a room increase does not solve only the visible queue.
Can online ED registration be used for someone with serious symptoms?
Online registration is intended only for situations the health system explicitly identifies as appropriate for advance entry. Anyone with potentially life-threatening symptoms should use emergency services or proceed directly to emergency evaluation; a digital queue must never replace triage.
What is an all-risk-ready emergency department?
It is a planning approach that considers routine operations alongside disasters, mass-casualty incidents, terrorism, and infectious outbreaks. Features may include separable screening and decontamination paths, controllable airflow, cleanable surfaces, and spaces that can convert to overflow, but the final design must follow current local codes and public-health requirements.
