The golden rules for hand hygiene bestpracticesŶ Please do it!¾because of hand transmission

Hand transmissionŶ Hands are the most common vehicleŶ Skin microbial floraŶ Resident flora long term, S epidermidis and othersŶ Transient floraShort term minutes-hrs-days-wksBacteria - S aureus (10-78%), VRE, GNB, C difficileFungi- yeastsViruses,-rotavirus, rhinovirus, HCVŶ Transmission requires 5 sequential steps

Step 1:Germs are present on patient skin andsurfaces surrounding the patientŶ Germs present on intact skinŶ Skin squames containing viablegerms are shed continuously from normalskin - immediate surroundings(bed linen, furniture, objects) becomecontaminatedŶ Pathogen and count can vary patient,microorganism and environmentalcharacteristicsPittet D et al. The Lancet Infect Dis 2006

Step 2:Patient germs contaminate HCW hands by directand indirect contactŶ Risk varies type and duration of patient care, location etcŶ Glove contamination similar to hand contaminationŶ Gloving does not fully protect hands from contaminationŶ In a general health-care facility,29% nurses carried S. aureusand 17 30% GNB on their handsŶ Hands contaminated even during³&OHDQ DFWLYLWLHV OLIWLQJ SDWLHQWV taking the patient's pulse etc),e.g. 100 1,000 CFU of Klebsiella spp.Pittet D et al. The Lancet Infect Dis 2006

Step 3:Germs survive and multiply on health-careworkers' handsŶ Germs can survive on hands for differing lengths of timeŶ The duration depends on several factors including the pathogen,humidity, skin area etcPittet D et al. The Lancet Infect Dis 2006

Length of survival of organismPathogenLength of survival of organismInfluenza virus24-48 hours on nonporous surfacesParainfluenza virus10 hours on nonporous surfaces; 6 h on clothingSARS-associated coronavirus24-72 hours on fomites and in stool samplesNoroviruses 14 days in stool samples; 12 days on carpetsHepatitis B virus7 daysClostridium difficile5 months on hospital floorsPseudomonas aeruginosa7 hours on glass slideAcinetobacter baumannii33 days on plastic laminate surfacesMRSA ZHHNV DIWHU GU\LQJ GD\V RQ SODVWLF ODPLQDWH VXUIDFHVVRE GD\V RQ FRXQWHUWRSV7

Step 4:Defective hand cleansing results in handsremaining contaminatedŶ Insufficient amount of product and/or insufficient duration ofhand hygiene action lead to poor hand decontaminationŶ Transient flora are still recovered on hands followinghandwashing with soap and water, whereas handrubbingwith an alcohol-based solution has been provensignificantly more effectivePittet D et al. The Lancet Infect Dis 2006

Step 5:Germ cross-transmission between patient A andpatient B, devices and environment via handsTransmissibility depends on type of surface, inoculum load, moisturelevel of surface, microorganism etcPittet D et al. The Lancet Infect Dis 2006

Impact of hand hygiene promotion on HAIŶ 1977- Feb 2011, 30 studies investigated the impact of handhygiene (as a single intervention) to reduce HAIŶ 27 showed that behavioural change, illustrated by improvedhand hygiene compliance, leads to the reduction of HAI,particularly BSI and SSIŶ Only 3/30 studies showed no significant impact on HAI butin 2 hand hygiene compliance did not increase significantlyŶ An increasing number of studies have investigated thecorrelation between alcohol-based handrub consumptionand HCAI rates B.

The geographical conceptualizationof the transmission riskHEALTH-CARE AREAPATIENT ZONECritical site withinfectious riskfor the patientCritical sitewith body fluidexposure risk

Patient zone and health-care areaŶ Focusing on a single patient, the health-care setting isdivided into two virtual geographical areas, the patientzone and the health-care area.Ŷ Patient zone: it includes the patient and some surfacesand items that are temporarily and exclusively dedicatedto him or her such as all inanimate surfaces that aretouched by or in direct physical contact with the patient(e.g. bed rails, bedside table, bed linen, chairs, infusiontubing, monitors, knobs and buttons, and other medicalequipment).

Health-care areaŶ Health-care area: it contains all surfaces in the healthcare setting outside the patient zone of patient X. Itincludes: other patients and their patient zones and thewider health-care facility environment. The health-carearea is characterized by the presence of various andnumerous microbial species, including multi-resistantgerms.

OPTIMAL HAND HYGIENE SHOULD BE PERFORMEDAT THEPOINT-OF-CARE

Point-of-careŶ Point-of-care place where three elements occurtogether: the patient, the health-care worker, and care ortreatment involving patient contact (within patient zone)Perform hand hygiene at recommended moments exactlywhere care delivery takes placeŶ A hand hygiene product (e.g. alcohol-based handrub)must be easily accessible and as close as possible (e.g.ZLWKLQ DUP¶V UHDFK WR SRLQW RI FDUH 3RLQW-of-care productsshould be accessible without leaving patient zoneThis enables HCW to easily fulfil the 5 indications(moments) for hand hygiene
