HAND WASHING

To educate all staffs of SAUH about hand washing.

To make standard handwashing practice throughout hospital.

To educate staffs about resident flora and transient flora.

To make handwashing practice a regular activity irrespective of monitoring.

OBJECTIVES

Hand washing:Hand washing is the fundamental part of standard precaution procedures and disease control helps reduce or prevent infection and transmission of microbes among people and objects.

Medical hand washing:Medical hand washingis a procedure done by health care personnel to prevent transmission of infection and it is done for 60 seconds.

Surgical hand washing:Surgical hand washing is the act of washing the fingernails, hands, and forearms with a bactericidal soap or solution in a prescribed manner for a specific period (3 to 5 minutes) before a surgical procedure.

Hand hygiene :Hand hygiene relates to the removal of visible soil and the removal or killing of transient microorganisms from the hands and may be accomplished using soap and running water or an alcohol-based hand rub. 

DEFINITION

The outer layer of bacteria found on your hands is termed as transient flora.

This layer is potentially the most dangerous for transmitting disease from one person to another.

Fortunately, it is also the most easily eliminated

by hand washing.

Transient flora

The deeper layer of bacteria is called Resident Flora.

This bacterial population is more likely to be made up of innocuous bacteria such as Staphylococcus epidermidis and Corynebacteria spp. (diptheroids).

They are resistant to washing, since they

occupy the deeper layers of skin

Resident Flora

S. epidermidis is not usually pathogenic, patients with compromised immune systems are often at risk for developing an infection. These infections can be bothnosocomial or community acquired.

S. epidermidis is also a major concern for people with catheters or other surgical implants because it is known to cause biofilms that grow on these devices.

Staphylococcus epidermidis

Corynebacterium  is a genus of Gram-positive, rod-shapedbacteria. They are widely distributed in nature and are mostly innocuous.

Handwashing FactsWe have between 2 and 10 million bacteria between fingertip and elbow Damp hands spread 1,000 times more germs than dry hands The number of germs on your fingertips doubles after you use the toilet Germs can stay alive on hands for up to three hoursMillions of germs hide under watches and bracelets and rings.

. 

If hands are not visibly soiled or visibly contaminated with blood or other proteinaceous material, the most effective method for reducing the number of pathogenic bacteria on the hands of personnel is using alcohol hand rub.
