From the ACEP 2026 Scientific Assembly: The Hidden Bottleneck in the ED Is Unresolved Decisions

Part of the “From the ACEP 2026 Scientific Assembly” FabrixMed Insights series.

The ED physician is not a limitless decision layer. When specialty questions remain unanswered, cognitive load becomes an operational constraint: attention is divided, handoffs slow down, and stable-but-uncertain patients wait for the next decision. A documented specialist perspective can help keep the right questions moving without replacing bedside judgment.

Why is cognitive overload an ED operations problem?

Emergency physicians make decisions in an environment built around interruption. A patient arrives, a nurse needs an order, a consultant calls back, a new result posts, and another patient becomes unstable. The work is not a sequence of neatly completed tasks. It is a continuous queue of clinical decisions competing for attention.

That is why cognitive overload should not be filed only under physician wellness. It is also a systems problem. The ED has finite attention, just as it has finite beds, nurses, and specialist coverage. When too many unresolved decisions remain with the same physician, the department has created another capacity constraint.

In a prospective direct-observation study of emergency physicians, clinicians experienced an average of 7.9 interruptions per hour and 9.4 interruptions per hour while prescribing. The study found that interruptions were associated with higher clinical prescribing-error rates, while multitasking was associated with higher legal or procedural error rates. The findings do not mean every interruption causes harm. They show why the system should not treat constant interruption as a free resource. Westbrook et al., BMJ Quality & Safety

What happens when every unresolved question stays with the ED physician?

The ED physician must own the emergency assessment, stabilization, and disposition decision. But not every decision requires the ED physician to carry the specialty question alone until a callback arrives.

Examples include:

• whether a stable patient needs an in-person specialty evaluation or can be managed locally;
• whether a treatment plan is reasonable while the patient remains at the current site;
• whether a transfer question is clinical necessity or simply lack of timely specialty access;
• what the admitting team needs to know before accepting the handoff; and
• whether a behavioral-health case requires synchronous evaluation, asynchronous review, or escalation under the organization’s approved pathway.

These are not decisions to automate. They are questions to route deliberately. If the right specialist can review the relevant information and document a recommendation, the ED physician receives an additional clinical perspective instead of another unresolved task.

Is decision fatigue measurable in the ED?

One retrospective study examined 9,848 visits across two freestanding emergency departments and found changes in throughput, patients seen per hour, and admission patterns later in 12-hour shifts. The study is not a universal model of every ED, and it cannot prove that fatigue alone caused the operational changes. It does show why the timing and accumulation of decisions deserve measurement alongside staffing, arrivals, and bed capacity. Decision-fatigue study

The practical question is not whether emergency physicians are resilient enough. It is whether the operating model is asking them to hold too many unresolved decisions in working memory when volume, interruptions, and acuity are already high.

What does a documented specialist perspective add?

A documented specialist perspective gives the ED team a defined clinical question, a specialist review, a recommendation, and a recorded next action. It does not transfer clinical responsibility away from the treating team. It makes the specialist-access step visible and easier to act on.

That distinction matters. A hallway curbside may be useful, but it can disappear into memory, a verbal handoff, or an undocumented callback. A structured consult record preserves what was asked, what information was reviewed, what the specialist recommended, and what remains outside the scope of that recommendation.

For an ED leader, that creates measurable operating points:

• time from a complete consult request to specialist review;
• time from specialist review to a documented recommendation;
• percentage of requests returned within the configured response expectation;
• number of requests escalated because the case required synchronous or in-person care; and
• cases where the recommendation changed the next action, disposition path, or handoff.

The goal is not to turn every clinical question into an asynchronous consult. The goal is to make the appropriate specialty-access workflow available when the patient is stable enough for it and the question is clear enough to route.

How can FabrixMed serve as the ED’s specialist-access fabric?

FabrixMed is not a replacement ED, a substitute for local governance, or a single-purpose telemedicine vendor. It is a sophisticated technology fabric that a health system can lay across its existing operating model.

An organization can configure the fabric around its own specialists, contracted providers, sites, specialty lanes, credentials, response expectations, escalation paths, and documentation requirements. A multi-site ED group can use the same underlying workflow while preserving local clinical ownership and site-specific rules.

ConsultBridge is the part of that fabric that helps route a defined clinical question to the appropriate specialist and preserve the response in a documented handoff. The specialist may be internal, contracted, FabrixMed-connected, or part of a hybrid coverage model. The value is not forcing one staffing model. The value is giving the organization a consistent way to make specialist access available where its current model has gaps.

What ConsultBridge does—and does not—solve

ConsultBridge can help reduce decision burden per patient when a stable-but-uncertain case is waiting on appropriate specialty input. It can support a documented perspective for disposition-relevant questions, treat-or-transfer decisions, handoffs, and defined overnight coverage pathways.

It does not reduce patient arrivals, create inpatient beds, eliminate every interruption, or replace the ED physician’s judgment. A crashing patient needs real-time clinical care. A patient requiring an in-person examination, procedure, or immediate intervention needs the appropriate bedside response. An asynchronous workflow has a floor, and a safe operating model has to define it.

The product claim is therefore straightforward: a documented specialist perspective when the ED team needs one, delivered through a configurable fabric the health system can adapt to its own people, policies, and sites.

What should ED leaders measure first?

Before introducing a new workflow, measure where decision delay is actually occurring:

1. Which specialty questions wait longest, especially overnight?
2. How often does the ED team wait for a callback before disposition or transfer can proceed?
3. Which cases are transferred because specialty input was unavailable rather than because the patient required capabilities not present locally?
4. How often does the admitting team receive a specialist recommendation that is incomplete, undocumented, or difficult to act on?
5. What percentage of requests are appropriate for asynchronous review, and which require synchronous escalation?

Those measures turn cognitive load from a general concern into an operating problem that can be designed around. The opportunity is not to ask physicians to absorb more complexity. It is to build a better way to distribute the decisions that the ED is already carrying.

The takeaway

The ED physician should remain responsible for the patient in front of them. They should not also be the only access point for every specialty question across the department.

FabrixMed gives health systems a configurable specialist-access fabric. ConsultBridge adds a documented specialist perspective when the ED team needs one—helping the organization move appropriate questions forward while preserving clinical judgment, escalation, and accountability where they belong.
