Researchers conducted a cross-sectional and comparative study, which included ICU registered nurses, staff physicians and auxiliary workers. They studied the use of a hand hygiene CCTV monitoring system compared to overt observation.
The study involved nearly 500 hand hygiene opportunities. The hand hygiene compliance rates were higher when only overt observations were performed as compared to CCTV observation — 35.43 percent versus 24.39 percent. However, both methods of observations demonstrated excellent reliability.
“We demonstrated that CCTV is an appropriate, reliable, and neutral method for observation of hand hygiene. However, there is no clear basis for incorporating a CCTV observation modality into a health care system that already operates an overt observation program,” study authors concluded.
