The Missing Middle: A Pragmatic, Zero-Infrastructure Solution for Alberta’s Emergency Department Crisis

By Helen Chedza Chilisa, Sunday Irowa Ogbeide, Samuel Osama Ogbeide

Alberta’s emergency departments (ED) are buckling under the weight of 12-hour wait times and catastrophic Emergency Medical Services (EMS) offload delays; a crisis that recently prompted emergency physicians in the province to sound the alarm on unsafe conditions.

Patients in our urban centres, particularly Edmonton, often must endure agonizing waits for minor, easily treatable complaints like a child with a midnight fever, an ear infection or a minor laceration.

The paradox is glaring. During business hours, that same patient would be seen within an hour at a local walk-in clinic or medicentre. However, illnesses and minor traumas do not respect the traditional 9-to-5 workday.

Due to the lack of a robust, after-hours “middle ground” of care, all patients are funneled into Level 1 trauma centres, creating a catastrophic bottleneck. The downstream effects are severe, most notably the trapping of EMS crews in hallway offload delays, effectively stripping our communities of critical 911 response capacity.

Furthermore, these profound delays create severe psychological distress and anxiety for vulnerable populations, particularly children and the elderly, who are forced to labour in crowded, high-stress waiting rooms for hours on end.

Combining frontline clinical medical practice, deep expertise in large-scale operational logistics and specialized insight into the psychological impacts of delayed care, we have observed that the friction in our urban EDs is myriad. Much of it stems from the heavy administrative burdens placed on acute-care hospital nursing staff; barriers that are largely non-existent in the leaner operations of clinics.

We do not need endless government studies to solve this, nor do we need to spend billions expanding the physical footprint of our city hospitals. We need to bridge the gap between acute and non-acute care with a model that is agile, rapidly deployable and economically viable for physicians.

The solution lies in a hybrid partnership model that utilizes mobile infrastructure and the incentivizing of family physicians to decompress the ED from the parking lot.

The two-stream triage system (Fig. 1)

The core of this model relies on redirecting low-acuity flow before it ever enters the main ED waiting room. Triage would remain precisely as it is today; conducted by experienced triage nurses at the hospital entrance. From there, patients are divided into two distinct streams:

Stream A (The main ED): Patients classified as CTAS 1 and 2 (Resuscitation and Emergent) are directed immediately into the traditional ED.
Stream B (The mobile clinic): Patients classified as CTAS 4 and 5 (Less Urgent and Non-Urgent) are diverted to a fully equipped, modular mobile clinic situated directly in the hospital parking lot.
The flex tier: CTAS 3 (Urgent) patients act as the system’s dynamic pressure valve, directed to either Stream A or Stream B depending strictly on the real-time capacity and wait times of the main ED.

Crucially, this is a bidirectional system. If a patient in Stream B rapidly deteriorates, or if a patient in Stream A is reassessed and downgraded in acuity, they can be seamlessly transferred between the two environments.

Infrastructure and operations: A public-private synergy (Fig. 2)

This model requires zero new permanent construction, utilizing a smart division of labour between the provincial government and private medical enterprise where health services are still covered by the government. The model brings private sector fiscal efficiency to interface with public doors without negatively impacting the responsibilities of the latter; the symbiotic interface is where the goals are achieved.

The infrastructure (publicly funded):

The physical space should not be a capital burden on physicians. The Ministry of Health, acting through Acute Care Alberta, would procure and provide the physical infrastructure using modular, winterized medical units, such as the health care-specific trailers manufactured locally in Alberta by companies like ATCO. These modular units are designed specifically for clinical use, deployable within weeks and would be stationed directly in the hospital parking lots with dedicated power and sanitation hookups.

The operations (privately managed):

While the government provides the structure, the operations are entirely outsourced to the private sector to ensure maximum efficiency and minimal bureaucratic bloat. The government would issue a Request for Proposals (RFP) for the management of these Stream B trailers.

Bidding: Local Primary Care Networks that are collaborative partnerships between local family physicians and AHS, established private clinic conglomerates or newly formed physician co-ops would bid for the operational contracts.
Management: The winning bidder operates the trailer as a satellite business unit. They are responsible for staffing the physician shifts, providing the clinic manager or administrative assistant, and maintaining a localized, rapid-charting Electronic Medical Record (EMR) system independent of the hospital’s heavier digital infrastructure.
Billing: The clinic manages its own billing using the incentivized, after-hours Stream B consultation codes, paying the moonlighting physicians directly and keeping a standard overhead percentage to run the unit.

This model essentially takes the highly efficient, high-volume operational machinery of a private walk-in clinic and drops it exactly where the need is most critical. This is at the hospital doors.

A model is only as successful as its ability to attract and retain physicians. Family doctors already possess the skills to manage CTAS 4 and 5 complaints; what they lack is the framework and financial incentive to do so after hours at a hospital site.

To staff these mobile units, we must implement a targeted billing structure. Physicians working in the Stream B mobile clinic would utilize special consultation codes that pay a premium of 20 per cent to 50 per cent higher than regular community clinic codes, scaled dynamically depending on the time of day or night and statutory holidays.

This mirrors the shift-based and time-of-day incentives already successfully utilized to maintain staffing in rural Alberta hospitals. By adequately compensating family physicians for moonlighting in these high-volume, low-acuity triage units, we create a willing workforce ready to clear the backlog.

We have straw-polled a few urban Family Physicians who all attest that they will be willing to do this work if the incentives are right.

We do not need to overhaul the entire provincial system overnight to see if this works. We need a targeted, data-driven, one-year pilot program.

To properly stress-test the model, the province should deploy mobile Stream B units to a maximum of four strategic locations:

Edmonton: One or two units stationed at major, chronically bottlenecked sites.
Calgary: One or two units at comparable high-volume sites.
Regional hubs: One unit in a busy, mid-sized urban centre like Red Deer, which frequently faces severe rural-to-urban diversion pressures.

Over 12 months, we can track exactly how many CTAS 4 and 5 patients are diverted, the reduction in overall ER wait times, the decrease in EMS offload delays and the cost-to-benefit ratio of the physician billing incentives versus the exorbitant cost of unnecessary acute-care hospital admissions.

We cannot continue to treat pediatric earaches with the same heavy, expensive administrative machinery designed to treat multi-trauma car accidents. By establishing contracted, mobile urgent-care trailers in our hospital parking lots, we can bypass the institutional bottlenecks of the main ED, free up acute-care beds, get our paramedics back on the road and finally provide Albertans with the timely, middle-ground care they deserve.
