Learning Objectives • Demonstrate knowledge of the principles of infection control • Recognize gaps in infection control infrastructure • Demonstrate proper selection and use of personal protective equipment
Personal Protective Equipment (PPE) • When used properly can protect you from exposure to infectious agents • Know what type of PPE is necessary for the duties you perform and use it correctly
Types of PPE • Gloves • Gowns • Masks (surgical and particulate respirator) • Boots • Eye protection (goggles and face shields)
Precaution Levels **All levels require hand hygiene** • Standard Precautions Transmission based precautions: • Contact Precautions • Droplet Precautions • Airborne Precautions
Standard Precautions • Prevent the transmission of common infectious agents • Hand washing key • Assume infectious agent could be present in the patient’s • Blood • Body fluids, secretions, excretions • Non-intact skin • Mucous membranes
PPE for Standard Precautions Wear: • Gloves • Gowns • Eye Protection and / or Mask If: • Touching • Respiratory secretions • Contaminated items or surfaces • Blood & body fluids • Soiling clothes with patient body fluids, secretions • Procedures are likely to generate splashes / sprays of blood, body fluids, secretions, excretions
Contact Precautions Taken in addition to Standard Precautions • Limit patient movement • Isolate or cohort patients • Gown + gloves for patient / room contact • Remove immediately after contact • Do not touch eyes, nose, mouth with hands • Avoid contaminating environmental surfaces
Droplet Precautions • Prevent infection by large droplets from • Sneezing • Coughing • Talking • Examples • Neisseria meningitidis • Pertussis • Influenza • Avian influenza (probable)
Droplet Precautions Taken in addition to Standard Precautions • Place patients in single rooms or cohort 3 feet apart • Wear surgical mask within 3 feet of patient • Wear face shield or goggles within 3 feet of patient • Limit patient movement within facility • Patient wears mask when outside of room
Airborne Precautions Taken in addition to Standard Precautions • Prevent spread of infection through very small (< 5 microns) airborne particles • Examples • Tuberculosis • Measles • Varicella • Variola
Airborne Precautions • Use for influenza patients when: • History of travel to country with avian influenza activity within 10 days AND • Hospitalized with severe febrile respiratory illness • Or are otherwise under evaluation for avian influenza
Airborne Precautions • N95 mask (or equivalent) for personnel • Check seal with each use • Negative pressure isolation room • Air exhaust to outside or re-circulated with HEPA filtration • Patient to wear a surgical mask if outside of the isolation room
Sequence for Donning PPE • Wash hands • Gown • N95 Particulate respirator • Perform seal check • Hair cover • Goggles or face shield • Gloves
Sequence for Removing PPE Remove in anteroom when possible • Untie gown and remove shoe covers • Gloves • Wash hands • Gown (and apron, if worn) • Goggles • Mask • Cap (if worn) • Boots • Wash hands
Avian Influenza • Likely large droplet transmission • Possible airborne transmission • Recommended PPE varies depending on situation
Interviewing - Asymptomatic Exposed Persons and Contacts • Low-risk activity • Routine use of PPE not recommended • Maintain 3 feet distance between interviewer and interviewee • Use proper hand hygiene • May use hand sanitizer (at least 60% alcohol) if hands not visibly soiled
Interviewing - Symptomatic Exposed Persons • Higher risk activity • PPE recommended in community and healthcare facility • Contact precautions • Droplet precautions • N95 respirator • In healthcare facility, person should be placed in airborne isolation room
Specimen Collection – Exposed Persons and Birds • High-risk aerosol-generating procedure • PPE recommended • Gloves • Gown • Goggles or face-shield • N95 or better respirator
