Efficacy of Alcohol-based hand-rub in comparison to hand washing in prevention of nosocomial infections Melinda Hawley BSN, RN-BC Purpose Analyze the efficacy of alcohol based hand-rub (ABHR) in comparison to traditional hand washing in the prevention and reduction in non-spore forming nosocomial infections. Results •Minimal literature available with RCT utilizing different hand hygiene preparations-may be due to broad nature of the study of efficacy •In 2011 approx 722,000 HAI & ~75,000 deaths from HAI (majority outside of ICU’s) •1:25 hospitalized patients with HAI on any given day and costing healthcare industry billions of dollars every year in non- reimbursed medical costs. •Hand hygiene compliance among HCW low (estimated <40%) •Multiple Barriers •ABHR most effective 55-70% alcohol concentration •Alcohol denatures proteins = reduced risk of infection •ABH against most Gram + and Gram - bacteria •Reduced risk of nosocomial infections caused by: •MRSA, VRE, Staphylococcus aureus and E-coli infections •Amount of ABHR used and dry time can affect efficacy •ABHR efficacy in comparison to: Plain soap: 99.9987% vs. 98.1379% effective (Zarpellon et al., 2008) •ABHR more effective than antimicrobial hand soap •99.99% vs. 99.68% effective, (Paulson et al., 1999) •Effectiveness reduced to 99.98% after 3 rd use (Paulson et al., 1999) •ABHR not effective against Clostridium difficile bacteria VS.
