Emergency departments face unique security challenges. The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) measures a hospital’s environment of care partly by how well it “controls access to and egress from security-sensitive areas.” For trauma centres and emergency departments — where emotions run high and vulnerable patients converge — the physical environment itself becomes a frontline defence against violence.
Ambulatory and ambulance entrances should be separate, with electronically operated locks, and glass should have high impact resistance. Access from waiting areas to treatment areas should be controlled. There should be restricted access from the remainder of the hospital into the ED.
Designing the Emergency Department for Safety
The physical layout of an emergency room should conform to established guidelines — such as those from the Australasian College for Emergency Medicine in their “Guidelines on Emergency Department Design,” or “The Impact of the Built Environment on Care Within A&E Departments” from NHS Estates in the UK. These frameworks recognise that design is not merely aesthetic; it shapes behaviour, movement, and ultimately, safety.
Yet access control is frequently lacking in trauma centre and emergency department environments — despite being one of the primary areas for improving security cited in the literature. Staff who have worked in EDs with robust security measures consistently note the difference it makes to their daily experience and sense of safety.
Access Control as a Cornerstone of Security
The route by which a patient, staff member, or visitor enters the department determines which areas they can reach. The ambulance entrance, leading directly to resuscitation and major injury areas, demands particularly tight control. Visitor routes must be managed to protect patient privacy and dignity while preventing unauthorised access to sensitive clinical spaces.
Access control starts with physical barriers and the enforcement of a privileged perimeter. ID badges, key-fobs, keycards, and keypads can effectively create zones within a facility that are accessible only to authorised personnel. An effective security team reinforces these physical measures by using visible visitor and patient badges alongside staff identification.
Over 18 months, these actions reduced the number of reported violent crimes by 65%.
Some hospitals have implemented sophisticated visitor management systems. Security staff or volunteers scan a visitor’s driver’s licence — the information is automatically entered into a database and a visitor pass is printed for the duration of their stay. Integrated with the hospital’s patient data system, it can verify registration before granting access.
One New York City hospital used identification badges and colour-coded passes to limit each visitor to a specific floor, while enforcing a two-visitor-per-patient limit. The results spoke for themselves.
Beyond Hardware: The Human Factor
Despite hospitals’ growing investment in security hardware, some professionals urge a different focus: training staff to assess and de-escalate potentially violent situations. Physical barriers and surveillance systems can only do so much.
⚠️ The limits of technology: “The best camera in the world can’t reach out and stop a bad guy from hitting you — we need more training for security and professional staff in how to handle these violent people, more than we need cameras to record the event.”
The lesson is clear: physical design and access control create the foundation for a safer emergency department, but they work best when paired with well-trained staff who can read situations and intervene before violence escalates. Hardware buys time. Skilled people change outcomes.
