Automated, interactive video content could improve hand-washing practices for better hygiene: Study

Arlington (Virginia) [US], February 3 (ANI): From smartwatches that track everything from the number of steps walked in a day and our blood oxygen levels, to mobile applications and countless videos helping our day-to-day activities, we have come a long way when it comes to innovation. Now a new study sheds light on a technology that can help in improving hand-hygiene practices.
The study was published in ‘American Journal of Infection Control (AJIC)’.
Findings from the study suggested that automated smart technology, including video engagement, could help improve hand-hygiene practices to reduce the spread of healthcare-associated infections (HAIs). They also suggested how this type of creative intervention could be adapted to sustain better hand-washing practices long-term.
“Appropriate and consistent hand washing is critical to reduce the spread of HAIs, but it has been notoriously challenging, costly, and time-intensive to increase and sustain best practices among both hospital staff and the general public,” said Lily Ackermann, MD, ScM, FACP, Thomas Jefferson University Hospital, and the paper’s lead author. “This study suggests that automated video engagement could offer an effective new approach to improve hand-washing duration.”
Good hand hygiene – including hand washing – is the simplest and most effective method to prevent HAIs. Effective hand washing involved both the washer’s technique and the duration of their wash. The U.S. Centers for Disease Control and Prevention (CDC) recommended that all individuals, whether in a healthcare setting or the general public, wash hands for a minimum duration of 20 seconds. Previous research and clinical evidence have shown that compliance with this and other hand-washing guidelines is generally low.
The study conducted by Dr. Ackermann and her colleagues assessed whether an automated, smart video engagement system could increase the number of individuals who meet the recommended 20-second hand-washing duration, as well as whether hand washers eventually became fatigued with the intervention.
The researchers developed an innovative system comprising smart, connected, hand-soap and towel dispensers synched to a computer that was programmed to display a rotating set of 20-second-long creative videos.
The system began playing the video on a display screen above the sink and timing the hand-washing duration when a user first dispensed soap onto their hands, and then stopped both the video and timing when the same user dispensed a towel to dry their hands.
Researchers installed and piloted two of the systems in staff bathrooms of a non-clinical hospital location and captured data for three defined periods: a control period of 3 weeks (during which no video played), followed by an “impact-video” period of 9 months, and then a “sustain-video” period of 17 months.
Findings suggested that video intervention significantly increased mean hand-washing duration and the number of users who achieved the recommended 20 seconds of hand washing as compared to the control.
During the “impact-video” and “sustain-video” periods, mean seconds of hand washing increased by 7.5 and 4.4 seconds, respectively, as compared to control (21.9 seconds, 18.6 seconds and 14.4 seconds; p<0.001). While only 21.8 per cent of users achieved hand-washing duration of > 20 seconds in the control group, 61.1 per cent in the “impact” group and 41 per cent in the “sustain” group achieved this duration, representing increases of 39 per cent and 19.2 per cent in the two video groups (p<0.001).
Researchers determined that hand-washing duration decreased from the mean by 0.5 seconds per month during the “impact” period and 0.1 seconds each month in the “impact” period. The greatest number of users achieved the targeted >20 seconds of hand washing at month 1 of the “impact” period followed by a 22 per cent decrease at month 3 and then decline to a new steady state of 45 per cent below the peak at month 11.
The researchers suggest that the decline in hand-washing engagement could be attributed to creative and message fatigue, and suggest that video content should be refreshed every 3 months to help sustain engagement and hand-washing improvements.
“This study and its findings are exciting, because they suggest a viable new approach for addressing a fairly intractable healthcare problem,” said Linda Dickey, RN, MPH, CIC, FAPIC, and 2022 APIC president. “Solutions that meaningfully improve and sustain good hand hygiene will reduce infections, save money and save lives,” she concluded.
