Continuous improvement trumps the mythical “90%”
The shortage of actual data on handwashing compliance in healthcare has evolved into a serious industry-wide overstatement of compliance. Knowing good things happen once a 90% level is achieved, reported handwashing rates quickly climbed to that number.
Professional advancement and even bonuses are “earned”, institutionalizing a standard of bad behaviors. The Joint Commission's norm is clearly stated in their Comprehensive Accreditation Manual for Hospitals. It says nothing about 90%.
