REASONS FOR NONCOMPLIANCE POTENTIAL ADVANTAGES
ALCOHOL‐BASED HANDRUBS
• Inaccessible hand hygiene supplies • Requires less time than hand washing
• Skin irritation • Acts quickly to kill microorganisms on hands
• Too busy • More effective than hand washing with soap and water
• Glove use • More accessible than sinks
• Didn’t think about it • Less irritating to skin than soap and water and can even
• Lacked knowledge improve condition of skin
