A recent study says video surveillance has comparable results to in-person observation when measuring hand-hygiene compliance, according to an article on the Becker's Infection Control & Clinical Quality website.
Researchers used video surveillance and in-person observation simultaneously and separately at four schools in Kenya over an eight-week period.
Video observation yielded similar behavior as in-person observation, the researchers found, but people were more likely to clean their hands when both methods were deployed, the article said.
