Staff at a Long Island hospital are regularly checked to see if they washed their hands using surveillance footage. Video cameras will start recording when a staff member enters an intensive care room, and the footage is sent to India where workers will make sure staff followed hand-washing procedures. Hospital-acquired infections cost about $30 billion and 100,000 patients are killed each year. Hospital staff only wash their hands about 30% of the time they are working with patients. Workers are also told to wash their hands for a certain length of time, long enough to sing “happy birthday,” in order for their hands to be clean enough, according to news reports.
