“There is a simple and effective way of getting hospital workers to wash their hands consistently: Watch them wash, and then congratulate them for having done so.

Employees at a Long Island hospital installed cameras with views of every hand-washing sink and hand sanitizer in an intensive care unit. For 16 weeks, without collecting identifying personal information, they monitored workers as they entered and left patient rooms. The results were reported last month in the journal Clinical Infectious Diseases.”
