It is estimated that pressure ulcers place a $1.2 billion annual burden on the U.S. health care system, partially because of the complexity of identifying, treating and managing these wounds. A patient simulator that provides real-time information will reduce the occurrence of preventable medical error costs through hands-on training and education.
The ulcer prevention detection simulator is a mannequin and real-time computer-based technology therapeutic device that mimics the human body to register pressure for biomechanical assessment capabilities. The device empowers clinical facilities to eliminate secondary costs arising from hospital-derived pressure ulcers, which are considered a “non-event” for Medicare billing purposes.
Researchers have developed a human patient simulator specifically for education in pressure ulcer management and prevention. This simulator mimics the bioinformatics of a geriatric patient and delivers real-time information to educate practitioners about the different biomechanical triggers that cause ulcer formation.
The simulator also teaches users to distinguish surface pressure from localized deep tissue stress.
The working prototype is supplemented by a computer interface and training manual, which makes it easily adaptable to a variety of situations. In addition to its educational features, the pressure ulcer simulator is capable of assessing the efficacy of preventative and therapeutic devices.
