The
Hospital Gang
ESCHERICHIA COLIgenerally lives a blameless life in the gut
but assumes a life of crime once he is allowed to roam in the hospital
PSEUDOMONAS Normally lives in soil and in water
storage tank. but, once he gets into the hospital, is notoriously difficult to remove
KLEBSIELLA. Lesser known resident of the intestine,
fond of hitchhiking on the hands of doctors and nurses. Known to take over entire wards.
STREPTOCOCCUS Still a common cause of throat infection
but also involved in more seriousoffenses against the rest of the person
PROTEUSA motile young bacterium, anxious to swim into the wrong places. Generally follows up the dirty
work of other bacteria
STAPHYLOCOCCUS AUREUSAlias Goldie the Grape, found
in the nose and on the hands of hospital staff but survives
for days in dusty places

ORGANISMS PRESENT ON THE HANDS
RESIDENT ORGANISMS• normal flora of the skin• deeply seated in the epidermis• not easily removed by single hand
washing• rarely cause infection• cause infection during implant
surgery and IV sites

HANDWASHING
• Considered to be one of the MOST important procedures in the prevention of hospital-acquired infection
![Page 15: HAND HYGIENE … THE EASY WAY!](https://reader035.vdocument.in/reader035/viewer/2022062323/568164ae550346895dd6ba2c/html5/thumbnails/15.jpg)

Factors Influencing Adherence to Hand-Hygiene Practices
• Observed risk factors for poor adherence to recommended hand-hygiene practices– Physician status (rather than nurses)– Nursing assistant status (rather than a nurse)– Male sex– Working in an intensive-care unit– Working during the week (versus weekends)– Wearing gloves/gowns– Automated sink– Activities with high risk of co-transmission– High number of opportunities for hand hygiene per
hours of patient carePitter D, 2000
![Page 18: HAND HYGIENE … THE EASY WAY!](https://reader035.vdocument.in/reader035/viewer/2022062323/568164ae550346895dd6ba2c/html5/thumbnails/18.jpg)
Factors Influencing Adherence to Hand-Hygiene Practices
• Additional perceived barriers to appropriate hand hygiene
– Lack of active participation in hand-hygiene promotion at individual or institutional level
– Lack of role model for hand hygiene– Lack of institutional priority for hand hygiene– Lack of administrative sanction of
noncompliers/rewarding compliers– Lack of institutional safety climate
Pitter D, 2000
![Page 19: HAND HYGIENE … THE EASY WAY!](https://reader035.vdocument.in/reader035/viewer/2022062323/568164ae550346895dd6ba2c/html5/thumbnails/19.jpg)
Factors Influencing Adherence to Hand-Hygiene Practices
• Self-reported factors for poor adherence with hand hygiene– Hand washing agents cause irritation and dryness– Sinks are inconveniently located/shortage of sinks– Lack of soap and paper towels– Often too busy/insufficient time– Understaffing/overcrowding– Patients needs take priority– Hand hygiene interferes with health-care worker
relationships with patients– Low risk of acquiring infection from patients– Wearing of gloves/beliefs that glove use obviates the
need for hand hygiene
Pitter D, 2000
![Page 20: HAND HYGIENE … THE EASY WAY!](https://reader035.vdocument.in/reader035/viewer/2022062323/568164ae550346895dd6ba2c/html5/thumbnails/20.jpg)
Factors Influencing Adherence to Hand-Hygiene Practices
• Self-reported factors for poor adherence with hand hygiene– Lack of knowledge of guidelines/protocols– Not thinking about it/forgetfulness– No role model from colleagues or superiors– Skepticism regarding the value of hand hygiene– Disagreement with the recommendations– Lack of scientific information of definitive impact of
improved hand hygiene on health-care associated infection rates
Pitter D, 2000

Indications for hand washing and hand antisepsis
• Antimicrobial impregnated wipes (i.e. towelletes) may be considered as an alternative to hand washing with non-antimicrobial soap and water. Because they are not as effective as alcohol-based hand rubs or washing hands with an antimicrobial soap and water for reducing bacterial counts on the hands of HCWs, they are not substitute for using an alcohol-based hand rub or antimicrobial soap
![Page 31: HAND HYGIENE … THE EASY WAY!](https://reader035.vdocument.in/reader035/viewer/2022062323/568164ae550346895dd6ba2c/html5/thumbnails/31.jpg)
