The cleanyourhands campaign is still considered a high priority for over 75% of NHS trusts, say researchers.
Researchers from the Royal Free Hospital and University College Medical School in London conducted an independent assessment of the campaign, launched by the National Patient Safety Agency in September 2004.
The results were presented this week at the annual Health Protection Agency conference in Coventry.
The researchers concluded it had been 'highly effective in changing hand hygiene behaviour', with a sustained increase in alcohol handrub use.
Just 18 months after it was rolled out to all acute trusts in England, 90% had alcohol handrub at patients' bedsides and 81% had campaign posters displayed in the majority of wards, researchers said.
