How Front-End Design Can Unlock Outpatient Capacity
Healthcare organizations are under constant pressure to increase access, improve patient satisfaction and grow revenue. When demand outpaces capacity, the instinct is often to think bigger: build another outpatient center, expand a campus or acquire another site. But before adding the next site, healthcare portfolio leaders should ask a critical question:
What if the problem isn’t your portfolio size? What if capacity is being constrained by patient flow?
Throughput determines asset performance.
When front-end processes (check-in, registration, intake, circulation) limit throughput:
- Downstream clinical assets sit underutilized
- Daily visit capacity is artificially capped
- High-demand locations appear “full” when they are operationally constrained
This creates a false signal in portfolio planning: It looks like you need more sites, when you may need better flow. Addressing throughput first can defer or eliminate new capital spend, improving overall portfolio performance without expanding your footprint.
Case Study: A Replicable, Efficient Outpatient Footprint
Lumexa Imaging’s Gateway Diagnostic Imaging Center in Mansfield, Texas demonstrates how design can unlock capacity within an existing footprint. Working within a 5,000-square-foot leased retail space, REES helped transform the environment into a high-performing imaging center.
Front-of-House—The First 15% Drives the Other 85%
Reception, a small office, a staff lounge and the waiting area come to roughly 15% of Mansfield’s footprint, the high end of the 10-to-15 percent range most outpatient facilities budget for front-of-house administrative space.
While an outpatient building’s entry can be tempting to minimize in favor of clinical space, the approach can be counterproductive. A scanner sitting idle because patients are backed up at one window costs more than the additional front desks that would have kept it running. Delays at the front desk ripple downstream, affecting every step of the patient experience. At a network scale, that’s lost volume and unrealized value.
“We often see breakdowns in flow at registration. When patients bottleneck at the beginning, it extends wait times throughout the visit and reduces overall throughput,” said Michael St. Clair, REES Healthcare Planner.
Up front, Gateway’s registration is split across multiple check-in stations, rather than a shared single window. Lumexa Imaging builds this model into its other locations, with a lobby to accommodate ~40 people and a deliberately stacked schedule to care for as many patients in a day as it can hold.
The 15% front-of-house investment isn’t overhead. It’s the infrastructure that keeps Gateway Diagnostic’s remaining clinical space operating at capacity.

Operational Efficiency—Moving Patients Through the Building
An efficient operational flow is also essential to serving more patients per day. For Mansfield, the team worked within the existing shell’s column grids and utility infrastructure to design a space that minimizes friction, keeping patients moving efficiently from check-in through discharge.
REES-designers organized the center’s MRI, CT, X-ray and ultrasound around a single central corridor. There is one shared core space in the middle for sub-waiting and dressing instead of duplicating those spaces around each modality. A clear entry to exit circulation path simplifies wayfinding. One way in and one way out.
Imaging modalities and control rooms are built around a single corridor at Gateway Diagnostic Imaging Center in Mansfield, Texas.
The Result—Maximize Throughput First, Then Broaden Access
With a design focused on efficient check-in and modality utilization, Mansfield can support up to 140 patient visits per day. “In a typical imaging center of this size with the four modalities present, we expect the facility to see between 92-140 patients per day,” Michael St. Clair said. “This design supports a higher volume of patients because it keeps people moving quickly through the imaging process.”
The facility’s efficient floor plan provides a repeatable framework that can adapt across multiple locations. REES assisted Lumexa Imaging in the design of two other sites, applying Lumexa’s proven prototype to centers in Forney and Waco, Texas. Lumexa continues to expand access, now operating 13 Gateway Diagnostic Imaging Centers across the DFW metroplex and more than 185 centers in 13 states. Gateway Diagnostic demonstrates that high-performing outpatient environments require intentional planning around how patients enter, move and exit.
The Bottom Line—A Smarter Way to Add Capacity
In many cases, the lowest-cost capacity gain is not new construction, it is improving how patients move through the front door.
Before pursuing a new site, consider:
- How much patient volume is currently lost to check-in delays?
- Are high-volume locations constrained by front-end processes?
- Could modest design or operational changes unlock additional throughput?
Maximizing outpatient performance requires more than proximity. It requires environments designed for both access and throughput, where every square foot contributes to patient flow and operational efficiency. Because the next unit of capacity may already exist. It just hasn’t been unlocked yet.
