As the global COVID-19 virus continues to spread, hospitals are struggling to provide patient care, ensure the safety of medical personnel, and protect vital supplies from theft. As IP technology continues to improve the functionality and performance of video surveillance, more hospitals are monitoring with digital care solutions. From thermal scanning cameras, to video analytics driven by machine learning, to remote monitoring IoT sensors, hospitals are using technology to fill the care gap and safely expand the service of patients with coronavirus.
Now more than ever, open platform video management software (VMS) technology is taking on a bigger role beyond traditional security at hospitals. The real-time data and observation can improve the safety of the healthcare environment and the quality of care, not only for patients but also for hard-working medical personnel.
Remote Video Monitoring
Many hospitals currently use network cameras for security surveillance throughout the interior and exterior of facilities. Different types of IP video devices can also assist hospital staff to safely monitor contagious patients, including thermal, infrared and high-definition cameras. An open platform VMS gives hospitals the ability to quickly and securely integrate such new capabilities and services.
Prior to the coronavirus outbreak, Nemours Children’s Hospital in Orlando, Florida, had deployed fixed network cameras in every patient room to provide an added level of monitoring beyond nurses and clinical staff. Cameras are equipped with a privacy LED light indicator, letting patients know when the camera is in use. When an alarm trigger is activated, highly trained paramedics from the hospital command center monitor the patient via live feed. The paramedics can also assist patients via audio and alert other rapid response teams if needed.
This video monitoring technology is changing the way Nemours performs patient rounds, according to Healthcare IT News. Before the outbreak, daily patient rounds would occur in the hallway, allowing a team of up to 14 allied healthcare professionals and parents to discuss the patient’s condition and coordinate a plan of care.
Nemours quickly revamped patient rounding so that a maximum of three people now comprises the hallway team, while other members of the care team connect remotely to the VMS using their own devices to participate. Nemours has conducted about 340 virtual rounding visits per week since it went live with the new system at the end of March. It has helped in saving personal protective equipment (PPE) and reducing direct contact with patients.
Machine Learning Video Analytics
Video analytics software can analyze every frame of video and flag potential issues as they occur, which allows hospital staff to make better, more informed decisions. Machine learning uses algorithms to discover patterns and generate insights from the video data. Deep learning, a more advanced subfield of machine learning, uses repetitive example-based training to teach video analytics software how to identify patterns, classify information and predict behavior from video surveillance.
Video technology also has the potential to notify nurses if a patient’s dressings have not been changed or a bed-bound patient needs assistance. Video analytics can alert hospital staff if a patient falls by distinguishing between the positional movement of a person lying down on a bed or sitting on the floor.
Video analytics can also increase efficiency. By analyzing patient behavior patterns at different hospital locations and times of day, analytics can improve staffing levels by providing accurate information about where staff members are being posted, versus where the highest amount of activity is occurring. This can help hospital administrators make the best use of resources and improve emergency procedures.
Telehealth and IoT Devices
Physicians can give remote care when patient data is linked to the hospital VMS. For example, in the Nemours’ cardiac unit, physiological monitor information is displayed on the VMS, allowing cardiac intensivists to monitor patients around the clock. Using remote connectivity to the VMS, cardiologists can quickly check on patients through their smartphones or mobile devices.
Healthcare providers are also finding ways to use medical-grade sensors to gather data and provide quality telemedicine to patients at home. A Boston hospital has adapted its telehealth video system for remotely monitoring coronavirus patients recuperating at home, according to NBC News. Patients wear IoT sensor devices for doctors to monitor their oxygen level and heart rate remotely. This can help free up hospital beds and save PPE supplies.
In Hong Kong, researchers and clinicians are using remote monitoring to better understand the coronavirus, according to the Wall Street Journal. Using medical-grade sensor devices worn by patients quarantined in their homes or hospitals, researchers can monitor and analyze real-time data, such as body temperature, respiratory rate, blood oxygen level and heart rate. Clinicians can then apply personalized, predictive analytics to provide more effective interventions.
As hospitals are stretched thin by this health crisis, open platform technology can continue to play a crucial role in integrating systems for staff shift monitoring, building control and management, traffic management and complying with regulations for hygiene, fire and environmental issues. More importantly, video surveillance can provide new solutions for protecting and monitoring patients who need it most.
