Abstract

The effectiveness of ultraviolet light disinfection of keyboards was assessed in the intensive care unit and emergency department of a pediatric hospital. Ultraviolet light disinfection was 67% effective (95% confidence interval, 46%-87%) in eliminating bacterial contamination as measured by quantitative bacterial culture.
