To the Editor: The association between poor hand hygiene of health care workers and nosocomial infection is well established.1 The National Hand Hygiene Initiative2 has been established to improve hand hygiene among health care workers, and the use of ethanol- or isopropanol-based hand sanitisers has been widely adopted in the hospital setting. To encourage their use by health care workers, many hospitals have undertaken extensive education programs and made hand sanitisers with high alcohol content readily available at all points of patient care. An unanticipated but potentially adverse outcome of this campaign is the intentional consumption of hand sanitisers by patients.
