Video Surveillance in Healthcare Enhances Patient Care

Video Surveillance in Healthcare Enhances Patient Care

Healthcare organizations are unique environments. They regularly contend with ongoing business challenges such as limited resources and rising costs. Adding to their challenges are 24/7 visitor traffic, confidential patient data, large supplies of pharmaceuticals, and emergency situations.

As a result, healthcare facilities are embracing any technology to help them be more efficient, including video surveillance technology. Cameras are now regularly installed throughout every type of healthcare facility to meet a diverse set of security and surveillance needs.

Multi-sensor technology is beneficial to hospitals looking to get the most out of their security budgets. With one device, data drop, or license, they can record several key areas like pharmacies, hallways, or lobbies with unique fields of view for each.

Cameras in the operating room help to “audit” surgeries to make sure certain procedures are followed and provide evidence in case of issues like “wrong sight surgeries," where surgery is performed on the wrong part of a body.

Increasing Use of AI

The use of artificial intelligence (AI) is spreading across the healthcare industry for a range of applications. Hospitals are complementing their cameras’ security monitoring performance with enhanced data-gathering capabilities that combine intelligent audio/video analytics and AI.

The result is targeted object detection and classification, which saves time for hospital security teams by speeding up forensic searches. When an incident occurs, locating a person of interest, for example, can take only a few minutes instead of having to sift through hundreds of camera streams.

AI is also playing a larger role in cameras used for license plate recognition, recording vehicle entries and exits and alerting staff to potentially dangerous activities in real time.

For example, all hospitals have to deal with issues like “dump and run” incidents. A car may drive by an emergency room entrance in the early morning hours, “dump” off a body that’s the victim of a criminal activity, and then speed away.

The hospital needs to know who was driving that car. With AI-based license plate recognition, they can simply plug in their search attributes—a male in a red shirt and blue pants, between 2:00 and 2:30 a.m.—and get quick hits on people or objects that match those parameters. It’s more efficient than calling down to the command center with a search request that could take an hour or more without AI.

Hospitals also keep building “watch lists” of people whose previous histories prohibit them from being on hospital grounds. Those individuals can be identified by their license plates while they’re still in the parking garage, and security teams can intercept them before they enter the facility. If they do get past the front doors, their movements can be tracked throughout the building.

Drug diversion policies are more common in hospitals, especially those with large quantities of pharmaceuticals or other attractive targets for theft. Nearly every hospital uses a Pyxis MedStation, mobile pharmacies designed for automated medication dispensing and allocation.

These carts are stocked with the daily medications needed for a floor or area, and they are only available to authorized users. However, unauthorized personnel using stolen or forged credentials can unscrew the backs of these carts for easy access to the drugs. With the right cameras constantly watching, if a pallet of medication is suddenly short one box, it’s easy to filter a search to specific areas and locate the missing assets.

A perfect example of new technology solutions for healthcare is Hanwha Techwin’s integration of IP pan-tilt-zoom (PTZ) cameras with a leading remote sitting video platform. Hospitals can now perform 24/7 centralized patient monitoring and conduct remote observation of high-risk patient rooms and specialized units.

The success of a joint solution like this comes down to the balance of enhancing patient care while creating more efficiency. It allows key staff, especially nurses, to use their time for higher-value activities without getting bogged down with time-intensive, tedious tasks.

It’s a welcome alternative to having a live person act as a “sitter” in a room monitoring a high-risk patient prone to falling out of bed or generally harming themselves. Beyond the health implications for the patient in these instances, the hospital has to pay for additional medication, new surgeries, and extended stays because that patient was harmed while in the care of the hospital.

Hospital staff can remotely check on patients from a central command center at the nurses’ station, keep an eye on various in-room equipment using motorized camera lenses, or view which way the patient’s body is turned.

They can look for different behaviors or movements that might indicate a person is about to fall or harm themselves, and then communicate to either the patient directly or alert other personnel to preemptively resolve the situation.

This shifts the patient care process from reactive to proactive, ultimately leading to better-quality care and a safer environment for everyone involved.

Hospitals often adjust their surveillance priorities to focus on different areas or activities. Removing an entire camera mount and housing to install a new camera is traditionally a time-consuming process. It requires an entire area to be shut down and dust-tents deployed to ensure proper air quality if a ceiling or wall is penetrated.

Cameras with a modular design, like the Hanwha Techwin X-Plus for example, use a magnetic camera module to make replacement or upgrading easier and faster. Remove a few screws, open the housing, and clip in the new module, and a unit is up and running in a few minutes.

Beyond safety, patient care, and efficiency, installing the right surveillance infrastructure also adds to a hospital’s competitive advantage. What doctor or nurse wouldn’t want to work for a facility with a reputation for being forward-thinking and willing to embrace the latest and greatest?

Looking ahead, the potential applications for security cameras in a healthcare setting are limitless, but the one constant will always remain achieving a balance of quality care, safety and, of course, efficiency.

  • Making Safety and Security Intrinsic to School Design

    Public anxieties about school safety are escalating across the country. According to a 2023 Gallup report, 44% of parents fear for their child’s physical safety at school, a 10 percentage-point increase since 2019. Unfortunately, these fears are likely to increase if the incidence of school tragedies continues to mount. As a result, school leaders are now charged with two non-negotiable responsibilities. The first, as always, is to ensure kids have what they need to learn, grow, and thrive. Sadly, their second responsibility is to keep the children in their care safe from threats and physical danger. Read Now
