Questions and Answers

What is the Spaulding Classification System?

  • A classification of bacteria
  • A system developed to classify medical devices based on risk of infection (correct)
  • A guideline for sterilization processes
  • A method for disinfecting surgical instruments

Match each device classification with its description:

Critical = Enters sterile tissue or the vascular system, requires sterilization Semi-Critical = Touches mucous membranes, requires sterilization if possible Non-Critical = Touches intact skin, requires low-level disinfection

What does it mean if a device is classified as critical?

It enters sterile tissue or the vascular system and requires sterilization.

Spaulding Classification System

Categorizes medical devices based on infection risk.

Critical Devices

Devices entering sterile tissue or the vascular system, requiring sterilization.

Semi-Critical Devices

Devices contacting mucous membranes, requiring sterilization or high-level disinfection.

Study Notes

Spaulding Classification System

  • Developed by Dr. E.H. Spaulding to categorize medical devices based on infection risk.

Device Classification

  • Critical Devices:

    • Enter sterile tissue or the vascular system.
    • Examples: implants, surgical instruments, needles.
    • Requires sterilization for safety.

  • Semi-Critical Devices:

    • Contact mucous membranes (excluding dental).
    • Examples: flexible endoscopes, laryngoscopes, endotracheal tubes.
    • Sterilization is preferred; if not possible, high-level disinfection (HLD) is required.

  • Non-Critical Devices:

    • Touch intact skin.
    • Examples: thermometers, stethoscopes.
    • Requires low-level disinfection.

Disinfection Methods

  • Bactericidal: Capable of destroying bacteria.
  • Disinfectant: Chemical agents that destroy or inhibit harmful organisms, excluding spores.
  • Sterile/Sterilization: Complete elimination of all living microorganisms.
  • High-Level Disinfection: Destroys all vegetative microorganisms, but not bacterial spores.
  • Low-Level Disinfection: Destroys vegetative bacteria forms.
  • Intermediate Disinfection: Effective against selected microorganisms, including most viruses and fungi, but not spores; used for non-critical items.

Best Practices for Disinfection

  • Review manufacturer Instructions for Use (IFU) before using chemical disinfectants.
  • Collect all disinfection accessories (measuring devices, soaking bins, timers) at the start of the process; ensure they are clean and made of non-limiting materials.
  • Quality test automated devices (dosing dispensers, suction irrigation devices, automated reprocessors) prior to starting disinfection.

Factors for Successful Chemical Disinfection

  • Check the expiration date of chemicals.
  • Be aware of reuse life date, if applicable.
  • Ensure appropriate concentration (diluted or full strength based on IFU).
  • Follow dilution/mixing requirements.
  • Maintain the correct temperature for the disinfectant.
  • Consider water quality and pH requirements for effectiveness.
