Quick Start — Hand Hygiene in Clinical Practice

Hand hygiene is widely recognised as the single most effective measure for reducing the transmission of healthcare-associated infections. Despite its simplicity, compliance among clinical staff remains imperfect, with audit data from acute hospitals consistently reporting rates between 40 and 70 percent. The World Health Organization's '5 Moments for Hand Hygiene' framework identifies the specific points in patient interaction at which hand decontamination is required: before touching a patient, before any clean or aseptic procedure, after exposure to body fluids, after touching a patient, and after contact with the patient's surroundings. Adherence to all five moments — rather than to any single one — is what produces a measurable reduction in cross-infection. Alcohol-based hand rub (ABHR) has become the preferred method in most clinical settings, since it acts more quickly than soap-and-water washing and disrupts a wider spectrum of pathogens. Soap and water remain mandatory, however, when hands are visibly soiled or after contact with patients suspected of carrying spore-forming organisms such as Clostridioides difficile, against which alcohol is not reliably effective. Effective infection control therefore depends not on a single technique but on selecting the correct method for the clinical situation.
