This document from BestCare Laboratory Services discusses the importance of hand hygiene in healthcare settings. It notes that healthcare acquired infections occur in 5-10% of hospital patients and cause over $10 billion in excess costs annually. About 1/3 of healthcare acquired infections are preventable through measures like hand hygiene using alcohol-based sanitizers or soap and water. Proper hand hygiene can significantly decrease infection rates and is the most effective way to prevent transmission between patients and staff. The document provides guidelines from the CDC on appropriate hand hygiene techniques and recommends a culture change is needed for sustained improvement in hand hygiene compliance.
