Do doctors use enough hand sanitiser?
Use more and let it dry for longer is the message from researchers
31st January 2020
Healthcare practioners may not be using the right amount of hand sanitiser, or letting it dry on their hands long enough, to achieve maximum protection, a recent study suggests.
Researchers did lab tests to see how long different amounts of gel and foam versions of alcohol-based hand sanitiser took to dry on nine volunteers' hands.
In the test of 0.75mL, 1.5mL, 2.25mL and 3mL dollops, smaller amounts of sanitiser sometimes dried within the 20-30-second time frame recommended by the WHO for optimal effectiveness.
