• | Health care workers describe 1.5 mL of alcohol based hand rub as too much. |
• | The recommended WHO drying time of 20-30 seconds is achieved with 1.5-2.25 mL ABHR. |
• | Eighty-six percent of users used a single pump of product, whether it is set at 0.75 mL or 1.5 mL. |
Résumé |
Background |
Alcohol based hand rubs (ABHR) are extremely effective at reducing microbial contamination and have an essential role in best practice hand hygiene described by the World Health Organization.
Methods |
We determined ABHR drying time when performing hand hygiene in a laboratory setting. Which was followed by identifying the amount of ABHR needed for complete hand coverage. When the aforementioned was analyzed real-time data were gathered to examine the amount used for hand hygiene in a hospital setting. In parallel hands of healthcare workers (HCWs) were monitored for drying time and perception on ABHR use.
Results |
In 86% (24,446,397/28,280,383) of the events a single dose of ABHR was used on clinical wards. Twenty-four HCWs expected hand hygiene to take 7.5 seconds (median; range 3-30 seconds). Forty-three HCWs show that 1.5 mL ABHR dose achieves the desired drying time according to World Health Organization guidelines (av. median 26 seconds), but is consistently perceived to have a longer drying time than expected (av. median 18 seconds). In-vivo results (n = 10) indicate that 2.25 mL ABHR is required for adequate coverage (82%-90%) of both sides of the hand.
Conclusions |
Results indicate that set standards for the use of ABHR do not match “in-vivo” behaviour of HCWs. Perceived drying times are shorter than actual drying time. The needed drying time to reach acceptable antimicrobial efficacy of ABHRs should be revisited.
