Infection Control and Precautions

Procedures for Routine Care, Cleaning, and Disinfection

  • Develop procedures for routine care, cleaning, and disinfection of environmental surfaces, especially frequently touched surfaces in patient care areas.
  • Standard precautions involve wearing gloves anytime you are about to test anything contaminated or handle equipment to prevent the transfer of microorganisms.
  • This may include cleaning equipment between uses.
  • Example: responsibility to wipe down incubators and transport incubators after every use between labor and delivery and the NICU.

Cleaning Procedures

  • Know how to clean, what to clean, and what to clean with.
  • Cavicide wipes are commonly used in clinical settings (purple top or white with a pink label).
  • Always wear gloves when using cavicide wipes, as they are toxic to the skin.
  • Hand hygiene: wash hands before entering and exiting every room.
  • Some places use foam in and foam out instead of washing, depending on the hospital.
  • Always wash hands depending on the patient.
  • In the NICU, scrub up to the elbows before every shift, including cleaning underneath fingernails.

Routine Cleaning and Care of Patients

  • Protocols vary depending on if patients have a central line, which may require chlorhexidine wipes or specific bathing patterns (e.g., bathing every 48 hours).
  • Each unit has its own protocols based on research, evidence, and quality improvement.

Environmental Services and Patient Areas

  • Computer on wheels (wows, formerly cows): wipe down the surface, mouse, and workplace to prevent the spread of bacteria and germs.

Standard Precautions

  • Also called universal testing.

Tier Two Precautions: Contact Precautions

  • Direct contact with a patient can lead to the spread of pathogens.
  • Wear gown and gloves when touching or near a patient on contact precautions.
  • Ensure there is a trash disposal in the patient room for disposing of contaminated materials.
  • Contact precautions are the most common type of precaution in the hospital.
  • Examples: wound infection, UTI colonized with a resistant organism.
  • Requires a private room and PPE equipment outside the room, including gowns.
  • Wear PPE if there are concerns a patient may have MRSA.

Droplet Precautions

  • Organisms spread through large droplets via mucous membranes through sneezing, coughing, and talking.
  • Wear a mask when within six feet of a patient on droplet precautions, and eye protection.
  • Example: patient with a trach who is positive for RSV.

Tier Two Precautions: Contact and Droplet

Airborne Precautions

  • Spread through air currents, requiring a negative pressure room.
  • Example: Tuberculosis (TB)
  • Requires an N95 respirator mask.
  • Notify public health officials (Department of Health) as TB is a public health emergency.
  • Common in homeless patients.
  • Wear a gown, gloves, and N95 mask when in a room with a patient who has TB.
  • Nursing students generally cannot go into rooms with airborne precautions.

Protective Isolation

  • Protects the patient from the spread of infection by limiting exposure to the outside world.
  • Patients need their own private room and PPE if you are close to them; often, the patients themselves wear a mask.
  • Patients who may need protective isolation: immunocompromised patients (e.g., oncology patients).
  • It is important to communicate to patients that the isolation is to protect them and prevent the spread of organisms like viruses, bacteria, or fungi to others.

Hospital Guidelines and Signage

  • Hospitals follow their own guidelines in addition to CDC guidelines.
  • Signage on doors indicates necessary precautions.
  • Airborne precautions only require an N95 mask, not a gown.
  • Flowers and fruits are often not allowed in protective isolation due to the bacteria they carry.

Sepsis

  • Sepsis is a quick, fast, and deadly condition, emphasizing the importance of prevention, identification, and treatment of infection.

Risk Factors for Sepsis

  • Everyone is at risk, but higher risk groups include the elderly, immunocompromised, and those with current infections.
  • Also at risk are the very young, those with recent surgery or breaks in the skin, and those with indwelling catheters or devices.
  • People who are homeless, college students, and those in nursing homes are also at increased risk.

Prevention

  • Hand washing is critical.

Patient Monitoring

  • Check patient vital signs.
  • Early signs may include an increased heart rate and faster breathing.
  • Changes in blood pressure may also be indicative of sepsis.
  • Watch for changes in breathing, fever, or chills.

Isolation Protocols

  • Use isolation rooms if needed, with dedicated equipment that should not leave the room.
  • Clean stethoscopes, especially the earpieces, before every shift.
  • Advocate for and communicate with patients while they are isolated.
