A woman carrying a Louis Vuitton purse and Macy’s shopping bag hurries through the front doors of a hospital in Washington, DC, and immediately eyes a recently installed weapons detection system (WDS) portal. Perhaps experienced with such fixtures at airports, she steps aside to allow others passage, then begins the ritual unburdening of bags, phones, keys, rings, pocket change, and other items that could possibly trigger an alert. A hospital security officer quickly intervenes and directs her to walk through. “But I have all these keys in my hand and other things,” the visitor objects. The officer assures her that she can pass with all those items, and she breezes through without a beep, partially amazed and partially relieved.
The hospital’s system uses advanced technologies and precise sensitivity settings to detect only weapons and not ubiquitous harmless items such as phones, keys, notebook computers, and umbrellas. While the officer’s principal role is to provide security, close behind are facilitating swift pedestrian traffic flow and offering excellent customer service. As this healthcare facility performs a trial of the system, the vast majority of visitor encounters are similar to this one: appreciation that hospital management prioritizes security, helpful and positive interaction with staff, and minimal delay.
The D.C. hospital soon realized that it could further improve throughput and the visitor experience by posting clear and hard-to-miss signage to set expectations for people arriving at the hospital. Hospital management planned to do so shortly after my visit.
That’s a tiny snapshot in the world of weapons-detection screening at healthcare facilities, where management must balance safety, convenience, and throughput. The author spent hours at entryways of healthcare facilities this winter observing examples of this intricate dance between security screeners, hospital entrants, and technology.
Perhaps no day was as busy as Valentine’s Day at a large hospital center in New York City, where hundreds of visitors, eager to see their loved ones, poured through the system carrying every possible type of bag and gift: Briefcases and balloons, valises and vases, truffles and totes. Similar to the Washington, DC, facility, visitors passed through the twin pillars with whatever they were holding or carrying. Secondary screening — bag checks or wand sweeps — occurred for the occasional person carrying a bag or other large item.
The exceptions were patients and visitors in wheelchairs, on walkers, or pushing strollers, where they are wanded in a separate area.
This article is the result of observing many such scenes and speaking to both security screeners and management. It assembles issues, challenges, and effective practices in deploying WDSs in healthcare environments.
Types of technology/system capabilities
WDSs range from basic metal detectors to elaborate affairs that combine metal detection, LiDAR, artificial intelligence to distinguish harmless items from dangerous ones, visual cameras with onboard analytics, radar, millimeter wave technology, and so on.
Layering various technologies is an effective way to maximize weapon detection, but that doesn’t mean healthcare institutions are best served by loading every available technology onto their solution. Selecting a WDS requires a balance of needs — determining exactly what types of items are you trying to detect, and to not detect — budget, staffing, location, logistics, throughput, false-alarm tolerance, and other factors.
Generally speaking, however, the more effective systems go beyond mere metal detection. Though a small number of hospitals I reviewed rely on that technology only, the more modern and sophisticated systems incorporate features such as LiDAR, AI, and visual detection — even catching people who try to circumvent the system. These latter systems also allow people to carry keys, phones, and other harmless metal objects through the system without triggering an alarm.
The more advanced systems that I witnessed were cloud based and integrated with multiple security and facilities interfaces, including access control, visitor management, mass notification and video surveillance. These facilities leverage the combination of security components to establish an enhanced security stance. For instance, security can quickly pinpoint the location of an individual, capture and collate various sources of threat data, and reduce response time. Moreover, the cloud-based platforms facilitate incident reporting, compliance documentation, guard check-in, data analysis, and mobile monitoring.
In fact, failing to integrate a WDS with other security technology is a missed opportunity, says Josh Phillips, a security practitioner and founder of the online community Physical Security Today. “Any output from the WDS is just as powerful a data point as a read at a door,” he emphasizes. “It just makes sense to integrate these systems with access control and video.”
Sites and locations
WDSs are obviously not practical or cost-effective for every type or size of medical facility. They are most frequently deployed in hospitals or healthcare centers with adequate funding that are located in higher-risk areas. Healthcare systems with multiple locations face the issue of allocating limited resources to multiple facilities, notes Phillips.
“There are so many outpatient facilities now,” Phillips says. “Hospital systems are very distributed. How do you decide where to install them?” The answer can be a combination of risk assessment, resources, community input, potential liability, and other factors.
Once you decide which facilities will receive them, the next questions are how many systems and where.
Some hospitals place WDSs at the entrance to the ER. Some situate them inside the main doors. Others cover both areas.
Chris Ciabarra, Chief Technology Officer and Co-Founder at Athena Security, who has overseen installation and maintenance of dozens of systems in healthcare environments, says that ERs are logical places for WDSs, considering that they have 24-hour operations, often deal with victims of firearms, and are the site of 40% of violent incidents in hospitals. But he adds that if other entrances don’t have WDSs, visitors can elude screening. (In fact, I was able to do just that at some sites.)
Ernie van der Leest, who has overseen healthcare security operations in Texas and Colorado, has witnessed that exact phenomenon. “Many hospitals use weapons detection systems at their ERs, but not at any other entrance,” he observes. “Anyone can get right around it.” His strong recommendation: use a WDS at every entrance.
Sometimes people can evade a WDS by entering the hospital through an adjoining medical office or facility. In those cases, if the hospital doesn’t want to add another WDS, connection points should either have electronic access control for staff use, an officer assigned to the entry, or a way to direct entrants back to a screening station.
What about limiting entrances, as schools do, to funnel patients, staff, and visitors to one or two entryways — which would improve security, reduce staffing costs, and minimize the number of WDSs to purchase?
Be careful with that approach, warns van der Leest. “If you shut down entrances that don’t have WDSs, you hurt the patient experience. People in wheelchairs, on crutches, the sick, the elderly might have to walk a long way to the only entrance.”

All staff should be trained on the specific system in use, as well as procedures that involve issues such as secondary screening, dealing with irate people, discovering a weapon, and requesting assistance.”
Staffing
All staff should be trained on the specific system in use, as well as procedures that involve issues such as secondary screening, dealing with irate people, discovering a weapon, and requesting assistance.
Then the institution should determine how many staff members are appropriate to operate a WDS.
According to a draft guideline issued for public comment on November 13, 2023, by The International Association of Healthcare Safety and Security, “The number of personnel assigned to the weapons detection process should be based upon the volume of people being screened, the type of monitoring equipment, search processes, secondary inspections, storage of belongings, etc.”
Athena’s Ciabarra says Department of Homeland Security (DHS) best practices specify two officers for normal conditions for high-volume entrances. DHS has even published a patron flow-rate formula for WDSs (see sidebar). Ciabara adds that the officer overseeing the screening should be able to both see the visual alert and hear the audio alert if an entrant triggers the system. The secondary screener conducts follow-up wanding and bag searches. One of those two officers also screens anyone who can’t pass through the portals or would definitely set off the WDS, such as the wheelchair bound.
A third screener can be considered at high-volume times, when risk is greater, when low wait time is critical, or as otherwise deemed viable by hospital management, Ciabarra adds.
Rarely did I witness three officers on duty at any facility, even urban hospitals at busy times. Often I only saw a single person do everything. Van der Leest confirms that my experience isn’t rare. In one hospital, I asked how long it would take to get backup if she found a weapon and someone threatening to use it. She didn’t know because it hadn’t happened yet.
