The screening decision is right. So is the exception. That’s what makes it hard.

Your ED screens for weapons, and the carve-out that waves through a critical patient or an ambulance is clinically correct and legally required. Nobody is wrong — and the exception is a permanent, published, unscreened corridor into the care area. That’s the part no one has addressed, because addressing it means arguing with no one.

The concession — without a “but”

Screening works. It is documented as effective, and it belongs at the doors it covers. The decision to let a patient with an obvious life-threatening emergency bypass the detector unchallenged — and to leave ambulance arrivals unscreened — is not a lapse. An ED cannot delay care to screen; EMTALA does not permit it and no security director should want it to. All of that is correct, and it stays correct.

And the exception it creates is not an edge case. It is a permanent, staffed, high-volume, published corridor into the care area — the ambulance bay, open around the clock by design. In one published post-installation analysis, 41% of the weapons that reached the care area came through the doors the policy exempts. The control is correct, the exception is correct, and the exception is where the weapons come in.

What we build

The layer at every entrance — including the one that doesn’t screen.

Which patients bypass screening is a clinical decision, and it should be. What we build is the physical layer that knows what came in through the door where nobody is standing — and the record that tells you what actually happened, not what got reported.

—The control, moved inward. The ED must be enterable by anyone at any hour — so the line holds at hardened triage and a controlled treatment-area transition, with the ambulance bay separately secured, not at a front door that can’t close.

—Duress that fits the geometry. Assaults happen at the bedside, not the desk — a fixed button under the counter is in the wrong place. Mobile, wearable duress with sub-room location is a claim about where a person is standing, and you can check it yourself.

—Routing to a person, not a monitor. The failure mode is an alert that reaches a screen nobody staffs. It has to reach a device carried by someone with a defined obligation to respond.

—The record as your denominator. Only about half of ED assaults are ever formally reported — so the system’s own record of what came in and what happened is the only honest count you have.

—Zoning that can compartmentalize a threat. The design question is whether the ED can be isolated — cross-corridor barriers closed to keep an event from reaching the rest of the hospital. The non-negotiable caveat most vendors skip: any automated locking must follow the AHJ-approved life-safety egress sequence, or you have traded one hazard for a worse one.

The physical layer we own

The clinical call is yours. The door where nobody’s standing is ours.

Which patients screen and which are exempt is a clinical and legal determination, and it belongs to you — along with de-escalation, restraint judgment, staffing, and the WPV program itself. We do not touch that decision, and we would not want to.

We build the layer at every entrance including the one the policy exempts, the duress that reaches a person carrying a device rather than a screen nobody watches, the location resolution that tells the responder which bay, and the retrievable record. The exemption is correct; naming the gap it creates is the whole of our part.

Start here

Start with your own policy. It’s in writing.

The check

Read the bypass clause. Then walk to the bay it names.

Start at your own written screening policy — the bypass is in it. Then walk to the ambulance bay and look at the door it exempts. Under twenty minutes; it stages nothing. No email; nothing stored.

The concession, the 41%, and the argument you already sell for a living — turned on your own published policy.

Before you leave

Roughly half of behavioral-health ED visits end in boarding — patients waiting hours or days on hallway gurneys in a department with no ligature-resistant design, because it was never built to be a psychiatric unit. And psychiatric units out-assault the ED per FTE. You are already running a de facto psych unit in a space that was never designed like one. Open behavioral health →
