Evaluating the tolerability and acceptability of an alcohol-based hand rub - real-life experience with the WHO protocol


Wolfensberger, Aline; Durisch, Nina; Mertin, Juliane; Ajdler-Schaeffler, Evelyne; Sax, Hugo (2015). Evaluating the tolerability and acceptability of an alcohol-based hand rub - real-life experience with the WHO protocol. Antimicrobial Resistance and Infection Control, 4(18):online.

Abstract

BACKGROUND: Optimizing user satisfaction with alcohol-based hand rubs (ABHR) may be vital to enhance hand hygiene performance. This study tested the tolerability and acceptability of a new ABHR (EVO9; Ecolab) in healthcare workers under daily working conditions and evaluated the practicability of the corresponding WHO protocol.
METHODS: We strictly applied the WHO single product ABHR evaluation protocol. A trained observer assessed hand skin conditions of healthy volunteers using at least 30 ml ABHR per day during their clinical work at baseline, day 3-5 and one month (visit 1-3). Participants rated ABHR tolerability and acceptability at visit 2 and 3. Additionally, we registered study time for participants and study team.
RESULTS: Among 46 volunteers, 76% were female; 37% nurses, 28% physicians. Skin was observer-rated "not" or "incidentally" dry in 64.4%, 77.8%, and 90.9% participants at visit 1, 2, and 3, respectively. EVO9 was scored ≥5 (progressive scale, 1-7) for appearance, intactness, moisture content, and sensation by 95.7%, 97.7%, 88.9%, and 97.8% participants at visit 3, respectively. All WHO benchmarks were exceeded except for "speed of drying" at visit 2, and "texture" at visit 2 and 3. Cumulative study time expenditure was 14 days for the observer and four days for participants.
CONCLUSIONS: EVO9 was well tolerated and accepted according to the WHO single ABHR evaluation protocol with the potential for improvement for stickiness. The WHO protocol is feasible but requires considerable time and logistics. It does not preclude bias, in this case especially due to the necessary switch to personal dispensers.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
