VR training tool helps clinicians improve infection control practices

Infection control researchers at Mass General Brigham have developed a virtual reality (VR) tool to train clinicians on core concepts in infection control, including cleaning and disinfecting portable medical equipment, to prevent the spread of infections throughout healthcare facilities. They successfully piloted the VR training tool at seven facilities across the United States, and their hope is such training can increase staff competency and improve patient safety. The work is published in Infection Control & Hospital Epidemiology.

Devices such as blood pressure cuffs, glucometers, and portable imaging machines are everywhere in healthcare, and study after study has shown healthcare is failing at cleaning and disinfecting them, leading to risk of healthcare-associated infections. We know that when core infection control practices are correctly and consistently applied, the risk to patients is reduced; but we also know that the way we have been teaching these practices for decades is not delivering."

Healthcare-associated Infections affect 1-in-31 patients, result in almost 100,000 deaths annually, and incur $28.4 billion in direct medical costs. Up to 75% of these infections are preventable through implementation of core infection prevention practices. Studies have reported between 25% to 100% of portable medical equipment to be contaminated and shared portable medical equipment has been implicated in transmission of healthcare-associated infections.

Shenoy and her colleagues developed an immersive VR module that uses head-mounted displays and guides learners through a simulated inpatient healthcare environment. The module incorporates gamification and visualization of invisible contamination, where learners review and apply cleaning and disinfection concepts to two different devices: a vital signs machine and a point-of-care ultrasound machine.

"We wanted clinicians to be able to 'see the unseen' risk and be completely immersed in a way that could lead to improved knowledge and skills when back in the real world," explained Shenoy. 

In the study's initial phase, 31 participants were trained and provided feedback, which was used to revise the training module. Then, an additional 44 participants tried the revised module, 39 of whom (88.6%) reported an overall positive experience. Survey comments from learners often touted their enjoyment of the immersive and virtual, hands-on environment of the platform. While half reported negative physical sensations (motion sickness is common among new VR users), only a few participants reported module challenges, such as difficulty with transporting portable medical equipment, donning and doffing their virtual gloves, or understanding instructions.

Additional research is underway and has moved beyond user experience and acceptability to focus on testing learners' knowledge, skills, and competency after training with the VR module.

"In busy, complex healthcare settings, a new kind of training is needed that increases muscle memory for these core infection control practices," said Shenoy. "Maybe not surprising, but certainly encouraging to our team, was that learners expressed joy and excitement for the training. We know that when learners are engaged, they are more likely to retain the information."
