Transmission of micro-organisms from the hands of healthcare workers to patients is a major cause of healthcare-acquired infections. In 2002, the US Centers for Disease Control and Prevention (CDC) published guidelines for healthcare workers that included the recommendation for alcohol-based hand rub for hand hygiene during patient visits. In this prospective study we surveyed parental and healthcare workers' preferences for the hand hygiene practices of emergency physicians. The study comprised 99 parents of ill or injured children presenting to our emergency department and 100 healthcare providers (64 nurses, 29 physicians and seven nurse practitioners) within the department. There was a clear and similar preference by parents and healthcare workers for hand hygiene using soap and water over alcohol cleansing rubs. Furthermore, both groups preferred hand hygiene before and after the examination and wanted to observe the physician perform this procedure. In conclusion, families and healthcare worker preferences for hand hygiene are not in keeping with recommendations published by the CDC. Educational interventions are needed to disseminate the CDC's guidelines and to promote compliance with evidence-based recommendations for hand hygiene.
