    Study Notes

    Standard Precautions

    • Standard precautions are routine infection control measures applying to all patients in all healthcare settings.
    • These precautions aim to prevent the transmission of infectious agents among patients and healthcare workers.
    • Their goal is to promote safe medical procedures.

    Nosocomial Infection

    • Nosocomial infections (HAIs) are infections acquired during healthcare, not present at admission.
    • They can arise in various healthcare settings (hospitals, long-term care, ambulatory) and even after discharge.
    • Such infections include occupational infections affecting staff.

    Types of Infection Transmission

    • Direct transmission occurs through contaminated medical equipment, implants, or devices
    • Indirect transmission involves contaminated medical staff, or visitors
    • Infection can also be transmitted via hospital facilities.

    Standard Precautions Outline

    • Define nosocomial infection
    • Define standard precautions
    • Hand hygiene
    • Personal protective equipment (PPE) usage
    • Instrument reprocessing
    • Aseptic techniques
    • Environmental cleaning and disinfection
    • Waste management

    Hand Hygiene and PPE

    • Hand hygiene is vital, particularly when caring for patients with acute respiratory illnesses.
    • Appropriate PPE usage is crucial.

    Standard Precautions and Isolation

    • Preventative practices are used for all clients regardless of diagnosis or present infection.

    Standard Precautions Apply To

    • Blood, body fluids, secretions, and excretions (except sweat), regardless of visible blood.
    • Non-intact skin
    • Mucous membranes.

    Standard Precautions Practice

    • Applying these precautions to all clients is a crucial practice in preventing infections.
    • These procedures represent the most effective way to reduce the risk of infections for patients and caregivers.

    Barrier Precautions

    • Barrier precautions are to minimize blood and body fluid exposure.
    • PPE (masks, gowns, gloves) are used as barriers between individuals and microorganisms, preventing transmission.

    Aspects of Standard Precautions

    • Hand hygiene
    • Gloves
    • Mask/Eye/Face protection
    • Gowns
    • Client-care equipment
    • Environmental control
    • Linen
    • Occupational health
    • Blood-borne pathogens
    • Placement of clients

    Hand Hygiene

    • Essential aspect of standard precautions to prevent cross-contamination between body sites on a single client.
    • Hand hygiene should be practiced between tasks and procedures on a client

    Gloves

    • Wear gloves when touching blood, body fluids, secretions, excretions, or contaminated items.
    • Change gloves between tasks.
    • Remove gloves promptly after use and clean hands immediately afterward.
    • Assess patients for latex allergies.

    Mask, Eye Protection, Face Shield

    • Protect mucous membranes (eyes, nose, mouth) when procedures or care activities might cause splatter or spray of blood, body fluids, secretions, or excretions (e.g. splashes).

    Gowns

    • Protect skin and clothing from soiling.
    • Select appropriate gowns based on anticipated fluid exposure.
    • Remove soiled gowns promptly after use.
    • Cleanse hands after removing gowns.

    Donning and Removing PPE

    • Proper procedures exist for donning (putting on) and removing gowns and masks.

    Client Care Equipment

    • Single-use items are discarded.
    • Reusable equipment must be cleaned and sterilized before reuse.

    Instrument Reprocessing

    • Processing healthcare instruments to ensure safety for reuse.
    • Single-use items are not reprocessed.

    Decontamination

    • Removal of contamination - sterilization, disinfection, and cleaning.

    Sterile

    • Absence of all microbial life.
    • Aseptic technique aims to minimize contamination from pathogens.
    •  Sterile technique intends to completely eliminate microorganisms (pathogenic and non-pathogenic).

    Clean

    • Absence of extraneous organic contamination.
    • Removal of non-essential matter.
    • Use of cleaning agents (detergents and alcohol).

    Disinfection

    • Removing or destroying microbes (except spores).

    Aseptic Techniques

    • Methods to reduce the risk of post-procedure infection.
    • Procedures include handwashing, surgical scrubs, using barriers, client preparation, maintaining a sterile field and proper operative procedure.

    Sterile Technique

    • Free of all microorganisms.
    • Common in operating rooms and specialized diagnostic areas.
    • Utilized in various procedures like injections, dressing changes, and catheterization.

    Sterile Field

    • A microorganism-free zone.
    • Complies with surgical asepsis principles when setting up a sterile field.
    • All items in a sterile field must be sterile.
    • Sterile items moving out of sight or below waist height are compromised.

    Sterile Field (continued)

    • Prolonged exposure to airborne microorganisms can compromise sterility.
    • Fluids flow with gravity, carrying microorganisms to sterile surfaces via capillary action.
    • Sterile field edges are not sterile.
    • Consciousness, alertness, and integrity are crucial for maintaining surgical asepsis.

    Establishing and Maintaining a Sterile Field

    • Process for sterile field preparation: opening wrapped packages, and maintaining the sterile field while handling sterile items (flaps, etc.)

    Environmental Cleaning

    • General cleaning of surfaces to maintain cleanliness.
    • Involves the physical removal of organic material (soil, dirt), followed by drying.

    Disinfection - Methods

    • Reducing the count of viable organisms; steam, boiling water, and chemical disinfectants are used.

    Low-Temperature Steam

    • Kills most bacteria and viruses via moist heat.
    • Utilizes dry saturated steam at 73°C for over 10 minutes.
    • Effective for items with lumens.
    • Unfit for heat-sensitive items.

    Chemical Disinfectants

    • Destroys microorganisms via physical or chemical processes.
    • Sensitivity to microorganism varies with different chemical or physicochemical agents.

    Sterilization

    • Eliminating all viable microorganisms and viruses (including spores).
    • Common methods encompass autoclaves, hot air ovens, ethylene oxide, low-temperature steam, sporicidal chemicals, radiation, and gas plasma.

    Sterilization (or sterilization)

    • Elimination of all transmissible agents (bacteria, viruses, prions) from surfaces, equipment, food, or biological mediums.
    • Distinguishable from disinfection processes where only disease-causing organisms are removed.

    Autoclaves

    • Steam under pressure sterilization above100°C.
    • Used for material, where steam and pressure are directly in contact with material.
    •  Require a 3-minute sterilization at 134°C (or 15 minutes at 121°C.)
    • Using color change indicator tape for evaluation.
    • Suitability, and not suitable , for heat-sensitive objects.

    Heat Sterilization

    •  Autoclave method involves using steam heated to 121°C at 103 kPa (15 psi) for 15 minutes.
    • Inactivates various microorganisms (fungi, bacteria, viruses, and bacterial spores).
    • Prions may not be always eliminated.

    Waste Management

    • Categorizing and managing different healthcare waste types.
    • Different types are hazardous (potentially harmful like chemical and radioactive agents, infectious agents), non-hazardous, general, or clinical.
    • Proper disposal is required to avoid risks.

    Disposal of Waste

    • General waste (tissues, plastic items that don't contain body fluids)
    • Clinical waste (contaminated items with bodily fluids, like gauze with blood, etc)
    • Sharp bin for sharp items.

    Steps of Medical Waste Management

    • Waste is sorted, stored temporarily, handled correctly, and finally disposed of.

    Infectious Waste and Sharps

    • Sorting at the emergence point(immediate area where it was created) is crucial.
    • Non-hazardous waste manages similarly as regular waste.
    • Sharps require disposal in safety boxes to prevent re-use.
    • Need proper equipment management (segregation, incineration, etc).
    • Treatment of blood in municipal sewer systems may be possible after the treatment.
