Study Notes

Asepsis

Aseptic techniques are essential to prevent healthcare-associated infections (HAIs)
Asepsis improves patient safety by reducing the risk of infection
Aseptic practices maintain the integrity of sterile products
Aseptic practices are designed for all clients in the hospital

Standard Precautions

Apply to blood, body fluids, excretions, and secretions (except sweat), non-intact skin, and mucous membranes
Reduce risk of transmission of microorganisms from recognized and unrecognized sources.

Hand Hygiene

Perform after contact with blood, body fluids, excretions, secretions, and contaminated objects whether or not gloves are worn.

Glove Usage

Wear clean gloves when touching blood, body fluids, secretions, excretions, and contaminated items.

Mask, Eye Protection & Face Shield

Wear a mask, eye protection, or face shield if splashes or sprays of blood, body fluids, secretions, or excretions are expected.

Gown Usage

Wear a clean, non-sterile, water-resistant gown if client care is likely to result in splashes or sprays of blood, body fluids, secretions, or excretions.
Gown protects clothing.

Contact Precautions

Use standard precautions as well as additional measures:
- Place client in a private room
- Wear clean gloves when entering the room
- Wear a gown when entering the room (if likely to have contact with bodily fluids or secretions)

Types of Asepsis

Medical Asepsis (Clean Technique):
- Reduces the number and spread of pathogens
- Aimed at preventing the transfer of microorganisms from one person, place, or object to another.
- Examples:
  - Hand hygiene
  - Use of Personal Protective Equipment (PPE):
    - Wearing gloves, masks, gowns, and eye protection
  - Environmental Cleaning: Routine cleaning and disinfecting surfaces, equipment, and instruments in healthcare settings
Surgical Asepsis (Sterile Technique):
- Practices that eliminate all microorganisms
- Used in procedures involving penetration of the skin, mucous membranes, or sterile body cavities.
- Examples:
  - Surgical hand scrubs
  - Use of sterile instruments and equipment
  - Sterile surgical attire

Key Principles of Asepsis

Sterility: Maintaining a sterile environment is critical; Any breach leads to infection
Cleanliness: Cleaning and disinfection of surfaces and equipment help minimize pathogens
Open Communication: Encouraging clear communication among healthcare providers, patients, and families helps identify and address safety concerns.

Patient Safety

Monitoring and Evaluation: Regularly assess patient safety performance through audits, feedback, and metrics to identify areas needing improvement.
Error Reporting and Analysis: Transparent reporting of errors and near misses to identify areas for improvement and prevent future incidents.
Evidence-Based Practices: Utilize standardized protocols and evidence-based guidelines to ensure consistent and safe care delivery.
Continuous Learning: Implement ongoing education and training programs to keep healthcare staff educated on best practices, emerging threats, and lessons learned.

Medication Reconciliation

Purpose: Ensures all medications a patient is taking are accurately identified and documented during transitions of care (e.g. admission, transfer, discharge)
Process:
- Gathering a complete list of all medications a patient is taking (including dosage, frequency, route, and reason for use)
- Comparing the patient's current medication list with the new medication list
- Identifying any discrepancies and resolving them with the healthcare provider
- Communicating the final medication list to all members of the care team

Memory B Cells

Some B cells become memory cells after activation, providing long-term immunity and a rapid response to re-exposure to an antigen.

B Cell Mechanism

Antigen Recognition: B cells have immunoglobulin (antibodies) that recognize and bind to specific antigens
Activation and Proliferation: Upon antigen binding, B cells require help from CD4+ T cells (via cytokines) for full activation and proliferation.
Antibody Production: Activated B cells differentiate into plasma cells that produce and secrete antibodies specific to the antigen
Antibody Function: Antibodies bind to antigens, neutralizing them directly or tagging them for destruction by other immune cells

Isolation Precautions

Implemented in healthcare settings to prevent the spread of infectious agents from patients to others.
Types of Isolation Precautions:
- Contact Precautions: Used for infections that spread through direct contact with an infected patient or contaminated surfaces.
- Droplet Precautions: Used for infections that spread through large droplets from the nose or mouth of an infected person (e.g. coughing, sneezing).
- Airborne Precautions: Used for infections that spread through tiny particles suspended in the air (e.g. tuberculosis, measles).
Purpose: To reduce the spread of infections and protect healthcare staff, other patients, and visitors.

Information Security

Access Control: Technologies to restrict access to patient care areas and sensitive information, ensuring only authorized personnel can enter
Data Privacy and Confidentiality: Protecting patient information through secure data storage, encryption, and strict confidentiality policies
Emergency Preparedness: Developing and regularly updating emergency response plans for various scenarios (e.g. natural disasters, violent incidents, data breaches)
Training and Awareness: Providing ongoing staff training on security protocols, recognizing potential threats, and responding effectively to security incidents.
Incident Reporting and Response: Establishing clear procedures for reporting security breaches, threats, and incidents (ensuring timely investigation and response).
