In order to drive continuous improvements in hygiene services, and help reduce the occurrence of healthcare associated infections, the Health Information and Quality Authority has conducted a second national review into the quality of hygiene services. This second National Hygiene Services Quality Review monitors the compliance of all the Health Service Executive and Voluntary acute care hospitals in Ireland against the National Hygiene Services Quality Review 2008: Standards and Criteria. It also compares the hospitals’ aggregate and individual scores with last year’s performance.
