What type of transmission-based precaution requires the health care worker to wear gloves and gown?

In addition to Standard Precautions, use Contact Precautions in the care of patients known or suspected to have a serious illness easily transmitted by direct patient contact or by indirect contact with items in the patient’s environment.

Illnesses requiring contact precautions may include, but are not limited to: presence of stool incontinence (may include patients with norovirus, rotavirus, or Clostridium difficile), draining wounds, uncontrolled secretions, pressure ulcers, presence of generalized rash, or presence of ostomy tubes and/or bags draining body fluids.

Additional Personal Protective Equipment (PPE) for Contact Precautions

Contact precautions are in addition to Standard Precautions

PLUS

Gloves

  • Wear gloves when touching the patient and the patient’s immediate environment or belongings
  • Remove gloves promptly after use and discard before touching non-contaminated items or environmental surfaces, and before providing care to another patient
  • Wash hands immediately after removing gloves

PLUS

Gowns

  • Wear a fluid resistant, non-sterile gown if substantial contact with the patient or their environment is anticipated
  • Do not wear the same gown for the care of more than one patient

Additional Procedures

Room

  • Private room or cohort, (room) patients infected or colonized with the same organism
  • Prioritize placement of patients in an exam room if they have stool incontinence, draining wounds and/or skin lesions that cannot be covered, or uncontrolled secretions

Patient

  • Instruct patients with known or suspected infectious diarrhea to use a separate bathroom, if available; clean/disinfect the bathroom before it can be used again

How contact transmission occurs:

Contact precautions are required to protect against either direct or indirect transmission.

Contact precautions are indicated for persons with gastrointestinal (diarrheal) illness, and incontinent persons including those who use incontinent products.

Direct Contact Transmission

  • Involves body-surface to body-surface contact and physical transfer of microorganisms between a susceptible person (host) and an infected or colonized person.
  • More often occurs between a health care worker and a patient than between patients.

Indirect Contact Transmission

  • Involves contact of susceptible person (host) with a contaminated intermediate object such as needles, dressings, gloves or contaminated (unwashed) hands.
  • Disease is more likely to develop following direct or indirect contact transmission when the pathogen is highly virulent or has a low infectious dose or the patient or health care worker is immunocompromised.
  • Poor hand hygiene is most often cited as a cause of contact transmission.

There are three types of transmission-based precautions: contact precautions (for diseases spread by direct or indirect contact), droplet precautions (for diseases spread by large particles in the air), and airborne precautions (for diseases spread by small particles in the air).  Each type of precautions has some unique prevention steps that should be taken, but all have standard precautions as their foundation.

Contact Precautions

  • Used for patients/residents that have an infection that can be spread by contact with the person’s skin, mucous membranes, feces, vomit, urine, wound drainage, or other body fluids, or by contact with equipment or environmental surfaces that may be contaminated by the patient/resident or by his/her secretions and excretions.
  • Examples of infections/conditions that require contact precautions: Salmonella, scabies, Shigella, and pressure ulcers.
  • In addition to standard precautions:
    • Wear a gown and gloves upon room entry of a patient/resident on contact precautions.
    • Use disposable single-use or patient/resident-dedicated noncritical care equipment (such as blood pressure cuffs and stethoscopes).
  • For certain organisms likely to have spores (like Clostridium difficile) and some disease with ongoing transmission (like Norovirus), “special” contact precautions are needed. In addition to the measures above, perform hand hygiene using soap and water and consider use of a hypochlorite solution (e.g., bleach) for environmental cleaning.

Droplet Precautions

  • Used for patients/residents that have an infection that can be spread through close respiratory or mucous membrane contact with respiratory secretions.
  • Examples of infections/conditions that require droplet precautions:  influenza, N. meningitidis (one of the causes of meningitis), pertussis (also known as “whooping cough”), and rhinovirus (also known as the “common cold”).
  •  In addition to standard precautions:
    • Wear a mask upon room entry of a patient/resident on droplet precautions.
  • A single patient/resident room is preferred. If not available, spatial separation of more than 3 feet and drawing the curtain between beds is especially important.
  • Patients/residents on droplet precautions who must be transported outside of the room should wear a mask if tolerated and follow respiratory hygiene/cough etiquette.

Airborne Precautions

  • Used for patients/residents that have an infection that can be spread over long distances when suspended in the air. These disease particles are very small and require special respiratory protection and room ventilation.
  • Examples of infections/conditions that require airborne precautions: chickenpox, measles, and tuberculosis.
  • In addition to standard precautions:
    • Wear a mask or respirator prior to room entry, depending on the disease-specific recommendations. Most diseases will require N95 or higher respiratory protection.
    • Place patient/resident in an airborne infection isolation (AII) room – a single-person room that is equipped with special air handing and ventilation capacity.
      • If the facility does not have an AII room, place the person in a private room with the door closed until the person is transferred to another facility with an AII room.
  • When possible, non-immune healthcare workers should not care for patients/residents with vaccine preventable airborne diseases (like measles and chickenpox).
