Healthcare workers
what are the most frequently encountered infectious agents by US health care workers
Bacteria and viruses
Organisms that have developed resistankce to one or more antibiotics
MDRO
Multidrug-resistant organisms
ex. MRSA
What is essential to prevent transmissions/infection
Proper cleaning and disinfecting
Reservoir for infectious organisms
Environment, things can survive on environmental surfaces for months if not cleaned.
What is the single most effective means of interrupting the transmission of infection
Hand hygine
Person to person transfer of pathogens
Direct contact
Person to object to person transfer of pathogens
Indirect contact
Large pathogenic particle coming in contact with the hosts conjuctivae or mucous membranes
Dropelet
How to prevent droplet infection
Goggles, mask, gloves, gown
Examples of droplet transmission disesases
Common cold, influenza, meningitis, pertussis, strep
Small pathogenic particles that remain suspended in the air for longer periods of time and are inhaled by or deposited on the host
Airborne (use a mask)
Examples of airborne diseases
Tuberculosis, Measles, Chickenpox
Who do standard precautions apply to
all patients in all healthcare settings
Guidelines for using hand sanitizer
Preferred in most clinical situations
Rub dry fro 20 seconds
Guidelines for using soap and water
Must use when hands are visibly dirty
When pathogen is known to be C.diff
After multiple applications of hand sanitizer
Wash 40-60 sec
When to perform hand hygiene
-Before and after pt contacts
-Before and after contact w/ possible contaminants
-Before and after toileting
-After sneezing, coughing, nose blowing
