    Study Notes

    Gloves

    • Serve as a protective barrier against exposure to contaminated items and infection sources such as secretions and blood.
    • Help minimize the risk of infection transmission to self and others.
    • Hand hygiene is mandatory after glove removal to prevent cross-contamination.
    • Distinction between exam gloves (non-sterile) and sterile gloves, which are used in specific medical contexts.

    Personal Protective Equipment (PPE)

    • Masks, eye protection, and face shields defend against splashes and sprays, protecting mucous membranes of the eyes, nose, and mouth.
    • Gowns shield clothing and skin from splashes and sprays; additional barriers include shoe covers and hair covers.

    Isolation Practices

    • Patient care equipment must avoid contamination to prevent spreading infections and protect against injuries from sharp instruments.
    • Linen handling should be minimal, kept away from uniforms, and may involve color-coded bags in certain agencies.

    Patient Placement and Transport

    • Patients likely to spread infection or those compromised require private rooms.
    • Patient transport should be limited when contamination risk is present; barriers are utilized to maintain aseptic conditions.

    Asepsis

    • Defined as the absence of disease-causing microorganisms; practices aim to minimize organism transmission.
    • Two types of aseptic techniques:
      • Medical asepsis focuses on controlling organism spread.
      • Surgical asepsis ensures an area remains free of all microorganisms.

    Medical Asepsis

    • Clean technique aimed at reducing microorganism number and controlling transmission, applicable to all patients.
    • Achieved through Standard Precautions, which are essential for all care providers in hospital settings.

    Standard Precautions

    • Essential for all patients regardless of their infection status, including hand hygiene, appropriate use of gloves, PPE, and properly disposing of equipment.
    • “Cough etiquette” and avoiding facial mucous membrane contact are critical components.

    Transmission-Based Precautions

    • Tier 2 precautions target known infectious agents, supplementing standard precautions.
    • Categories include:
      • Contact: necessitates private rooms, gloves, and gowns.
      • Droplet: requires private rooms or cohort, with masks.
      • Airborne: mandates private rooms with negative-pressure airflow and masks.

    Infection Control Measures

    • Hand Hygiene: considered the most vital method of infection control, affecting all forms of precautions.
    • Use of antiseptic agents such as alcohol-based hand rubs, and frequent handwashing with soap and water, especially when visibly soiled or dealing with specific pathogens like C. difficile.

    Hand Hygiene Recommendations

    • Wash hands before patient contact, before clean or aseptic procedures, after patient interactions, and after using the restroom or eating.
    • Proper handwashing technique involves using water, soap, ample lather, and friction for at least 20 seconds, ensuring effective cleaning.

    Isolation Practices Summary

    • Essential practices to prevent microorganism transmission, emphasizing the appropriate use of PPE based on situational assessment.
    • Consistent hand hygiene is critical before and after any patient-care interaction.

    Types of Pathogens

    • Common infectious agents include bacteria (e.g., E. coli, TB), viruses (e.g., herpes, HIV, hepatitis), fungi (e.g., Candida albicans), and parasites (e.g., protozoa and worms).

    Infection Overview

    • Infection occurs when microorganisms invade a host.
    • Stopping an infection involves eliminating or controlling the pathogen's spread.
    • Health care providers can interrupt transmission through stringent hygiene practices and the use of personal protective equipment (PPE).

    Methods of Transmission

    • Direct Transmission: Involves physical contact or droplet spread.

      • Includes touching, kissing, and particle spread from sneezing or coughing within 3 feet.

    • Indirect Transmission: Involves intermediate objects or vectors.

      • Vehicle-borne: Contaminated surfaces, food, or fluids.
      • Vector-borne: Animals or insects (e.g., flies, mosquitoes, ticks).

    • Airborne Transmission: Very fine particles remain suspended in the air and can travel with air currents, facilitating diseases like TB and COVID-19.

    Healthcare Associated Infections (HAIs)

    • HAIs can be endogenous (originating from the patient) or exogenous (from the healthcare environment).
    • Iatrogenic infections stem from medical procedures or contaminated equipment.
    • Common sites for HAIs include the urinary tract, often associated with improper catheterization techniques.

    Asepsis and Infection Control

    • Asepsis: Absence of disease-causing microorganisms.
    • Aseptic Technique:
      • Medical Asepsis: Reduces the number and spread of microorganisms (Standard Precautions).
      • Surgical Asepsis: Ensures complete sterility in specific medical procedures.

    Standard Precautions

    • Applied to all patients, regardless of their infection status.
    • Aims to decrease transmission risks and protect both patients and healthcare workers.
    • Practices include:
      • Hand hygiene
      • Use of gloves and PPE as needed
      • Proper disposal of contaminated equipment
      • Implementation of cough etiquette

    Hand Hygiene

    • Recognized as the most critical action to prevent the spread of infection.
    • Techniques include:
      • Using alcohol-based sanitizers and soap/water, especially when hands are visibly soiled.
      • Specific handwashing guidelines from the CDC are recommended before and after patient contact or exposure to contaminated surfaces.

    Isolation and Personal Protective Equipment (PPE)

    • Isolation practices are vital in controlling pathogen transmission.
    • PPE includes gowns, gloves, masks, and eyewear, chosen based on risk levels.
    • Proper application of PPE specifies a sequence for donning and doffing to minimize contamination risk.

    Key Recommendations for PPE Usage

    • Always apply PPE before patient contact and remove it carefully afterward.
    • Follow the doffing sequence: gloves, gown, eyewear, mask, followed by hand hygiene.
    • Distinguish between contaminated and clean areas of PPE during removal.

    Summary of PPE Application

    • Always keep hands away from the face while using PPE.
    • Dispose of used PPE appropriately to prevent cross-contamination.
    • Hand hygiene is essential immediately after PPE removal to maintain a sterile environment.
