Hand hygiene and glove use

–The use of gloves does not replace the need for cleaning your hands!

–You should remove gloves to perform hand hygiene, when an indication occurs while wearing gloves

–You should wear gloves only when indicated otherwise they become a major risk for germ transmission

Alcohol-Based Handrubs: What

benefits do they provide?• Require less time

• More effective for standard handwashing than soap

• More accessible than sinks

• Reduce bacterial counts on hands

• Improve skin condition

When should you wash your hands?

Although it's impossible to keep your hands germ-free, times exist when it's critical to wash your

hands to limit the transfer of bacteria, viruses and other microbes.

Barriers to hand washing

Can you find the sink in this picture ?

Abdullah A. Idrees

Barriers to hand washing

The sink mentioned in the previous

slide is located behind the

patient’s bed and behind several IV

pumps.

Self-Reported Factors for Poor Adherence with Hand

Hygiene Handwashing agents cause irritation and dryness Sinks are inconveniently located/lack of sinks Lack of soap and paper towels Too busy/insufficient time Understaffing/overcrowding Patient needs take priority Low risk of acquiring infection from patients

Health care workers

Nurses, doctors and other healthcare

workers can get 100s or 1000s of bacteria on their hands by doing

simple tasksCulture plate showing growth of bacteria 24 hours after a nurse placed her hand on

How clean are you???

Abdullah A. Idrees

Abdullah A. Idrees

Why should you clean your hands?

Any health-care worker, caregiver or person involved in patient care needs to be

concerned about hand hygieneTherefore hand hygiene does concern you!

You must perform hand hygiene to:protect the patient against harmful germs

carried on your hands or present on his/her own skin

protect yourself and the health-care environment from harmful germs

Abdullah A. Idrees

Hand hygiene must be performed exactly where you are delivering health care to patients (at the point-of-care)

During health care delivery, there are 5 moments when it is essential that you perform hand hygiene ("My 5 Moments for Hand Hygiene" approach)

The golden rules for hand hygiene

To clean your hands, you should prefer handrubbing with an alcohol-based formulation, if available. Why? Because it makes hand hygiene possible right at the point-of-care, it is faster, more effective, and better tolerated.

You should wash your hands with soap and water when visibly soiled

You must perform hand hygiene using the appropriate technique and time duration

5 Moments for

Hand Hygiene

Abdullah A. Idrees

Abdullah A. Idrees

PatientRefers to any part of the patient, their clothes, or any medical device that is connected to the patient

If the patient were to get out of bed and walk off – what would still be attached to them?

Abdullah A. Idrees

Immediate Patient Surroundings

A space temporarily dedicated to an individual patient for that patient’s stay Includes:

• Patient furniture and personal belongings • Medical equipment – BP machine, monitor• Medical chart • Anything touched by HCW while caring for that patient
