Isolation Precautions

Isolation is the process of separating sick people from healthy people during a period of communicable conditions in order to stop or slow the spread of infection. The nurses or medical staff utilize an isolation approach to stop the transmission of infectious germs or microbes. The term "barrier nursing technique" is often used.

Purposes:

• To reduce the number of infections in a certain, known area.
• Must avoid coming into contact with the sick person directly.
• To prevent infection in patients, employees, and visitors.
• To lower the number of infections linked to hospitals.
• To lessen the spread of microorganisms.
• Must keep nurses' uniforms clean in order to protect both them and others from potential illness transmission.

Principles:

• Keep the patient in the isolation chamber, which, depending on the physical setup, may be a unit type or illness type.
• Prior to nursing the patient, receive the appropriate immunizations.
• When you get skin lesions, a sore throat, or any other symptoms that indicate diminished resistance, let your manager know.
• Keep up good aseptic procedures.

Types of isolation precautions

Transmission-based Precautions:

The goal of transmission-based precautions is to stop the spread of pathogens that are highly contagious or have significant epidemiological significance in hospitals. These patients are those who have been confirmed or are suspected of having these infections. Airborne, droplet, and contact precautions are the three different categories of transmission-based precautions. When treating diseases with multiple transmission pathways, they can be combined. They must be used in addition to standard precautions, whether used separately or in combination.

Contact Precautions: 

Used to stop the direct or indirect transfer of epidemiologically significant organisms from an infected or colonized patient. Skin-to-skin contact and physical transfer of microbes from an infected or colonized person to a susceptible host are examples of direct-contact transmission. This can happen when staff members turn, bathe, or engage in other physically demanding patient care tasks. Direct-contact transmission can also happen between two patients, with one acting as the source of the infectious microorganisms and the other as a susceptible host (for example, by hand contact). Indirect contact transmission occurs when a susceptible host comes into contact with an intermediate, typically inanimate, contaminated object in the patient's environment. Contact Precautions apply to specified patients known or suspected to be infected or colonized (presence of microorganism in or on patient but without clinical signs and symptoms of infection) with epidemiologically important microorganisms that can be transmitted by direct or indirect contact. Sources of infection are draining wounds, secretions, and supplies.

Precautions must be taken in contact diseases:

• Take the usual safety precautions.
• Patients are housed in one room.
• When entering the room, put on a pair of clean, non-sterile gloves.
• When entering the room, put on a clean, non-sterile gown.
• Limit the patient's transportation out of the room.
• Draining wounds shall be covered with clean dressing.

Droplet Precautions:

Droplet precautions are intended to lower the possibility of infectious agent transmission by droplets. Droplet transmission occurs when large-particle droplets (larger than 5 mm in size) containing microorganisms produced from a person who has a clinical disease or who is a carrier of the microorganism come into contact with the conjunctivae or the mucous membranes of the nose or mouth of a susceptible person. Droplets are produced from the source individual most often when they cough, sneeze, or talk, as well as when suctioning and performing bronchoscopies. Because large-particle droplets do not stay suspended in the air and often only travel short distances, approximately 3 ft or less through the air, transmission by large-particle droplets necessitates intimate contact between source and recipient individuals. Droplet transmission can be avoided without the need for specialized air handling and ventilation because droplets don't stay suspended in the air. Any patient with a pathogen that is epidemiologically significant and that can be spread by infectious droplets is subject to Droplet Precautions.

Precautions must be taken in droplet infection.

• Take the usual safety precautions.
• Put the patient in a solitary space.
• When working within 1-2 meters of the patient, put on a surgical mask (3 to 6 feet).
• When working within 3 to 6 feet of a patient, wear a non-sterile gown.
• Remove the mask from the patient's room and dispose of it properly.
• If transport is required, cover the patient with a surgical mask.

Airborne Precautions:

The goal of airborne precautions is to lessen the possibility of infectious pathogens being transmitted through the air. Airborne droplet nuclei, which are microscopic particles that are 5 um or less in size and are left over after evaporated droplets, or dust particles that contain the infectious agent are what cause airborne transmission. In order to prevent airborne transmission, special air handling and ventilation are needed. Microorganisms carried in this way can be widely dispersed by air currents and may be inhaled by or deposited on a susceptible host within the same room or over a longer distance from the source patient, depending on environmental factors. Patients known to be infected with or suspected of being infected with epidemiologically significant infections that can be spread are subject to airborne precautions.

Precautions must be taken in air borne disease.

• Take the usual safety precautions.
• Place the patient in a solitary space with a controlled negative air pressure.
• Keep the doors shut at all times.
• Everyone entering the space needs to wear a N95 respirator.
• After closing the door to the patient's room, remove the N95 mask.
• Only move and convey the patient outside of the room when absolutely necessary.

Universal Precaution/Standard precaution:

Healthcare workers adopt a set of infection control procedures known as "Universal Precautions" to lessen the spread of pathogens in healthcare facilities. The prevention of parenteral, mucous membranes, and non-intact skin exposure of healthcare workers to bloodborne pathogens involves practices such as avoiding contact with patients' blood and bodily fluids, wearing personal proactive equipment, including hand washing, correct handling of infected instruments, and adhering to aseptic techniques. Universal/Standard Precautions shield patients and healthcare workers against infectious pathogens. The Bureau of Communicable Disease Epidemiology in Canada and the Centers for Disease Control and Prevention in the United States first created Universal Precautions in 1987 and 1989, respectively. In 1996 these practices were replaced by the latest approach known as standard precautions.

No of their diagnosis or suspected infection status, Standard Precautions are those precautions created for the care of ALL patients in hospitals. Its primary purposes are:

• All bodily fluids, secretions, and excretions, whether or not they have visible blood in them, including:
  • sputum
  • urine or feces
  • nasal secretions
  • vomitus/emesis
  • spinal fluid/cerebrospinal fluid
  • semen
  • synovial, pleural, peritoneal, pericardial, amniotic fluid
• All moist body surfaces, mucous membranes both intact and non-intact
• Blood
• Mucous membranes
  • All patients, not just those with established infections, are subject to standard safety procedures. When contact with potentially infectious material is expected, these precautions should be taken. The common safety measures comprise:
  • Hand-Washing
  • Appropriate use of Personal Protective equipment
  • Gloves
  • Mask, Eye Protection, Face Shield, Gown
  • Proper housekeeping and management of spillage
  • Safe handling of patient care equipment
  • Safe waste handling and Disposal of infectious waste and Sharp Objects

Forms of Isolation

Strict Isolation:

• Diseases that transmit through the air and occasionally through contact are treated with it.
• To stop the spread of contagious diseases, patients must be isolated.
• People held in severe isolation are frequently housed in a separate room.
• These rooms include a dedicated bathroom, caregiving supplies, a sink, and a garbage disposal.
• In cases of rabies, tetanus, gas gangrene, anthrax, scabies, leprosy, and venereal illnesses, it prevents dissemination by touch.
• In order to avoid cuts and abrasions on their hands, nurses must often and thoroughly wash their hands.
• Gowns, masks, and gloves must be donned before entering a private room and must be worn upon arrival.
• Utilize throwaway items, and dispose of them correctly.
• Send reusable items for cleaning and sterilizing.

Contact Isolation:

• To stop the spread of infections that can spread through contact, contact isolation is used.
• Impetigo, herpes simplex, infection by resistant germs, and other conditions that do not require rigorous measures but can be spread by close or direct contact are prevented.
• Gloves and, in rare situations, a gown are required for healthcare professionals who come into touch with patients who are on contact isolation.

Respiratory Isolation

• When a disease is conveyed by breathed particles, respiratory isolation is utilized.
• In cases of diphtheria, pulmonary TB, meningitis, whooping cough, rubella, mumps, pneumonia, and scarlet fever, it reduces droplet transmission.
• A mask must be worn by everyone who will be in close proximity to or exposed to such a patient.
• When coughing, instruct the patient to cover their mouth and nose with a handkerchief or tissue paper.
• When collecting sputum samples, use caution.
• Before reusing the handkerchiefs, either properly dispose of the tissue papers or clean and disinfect them. Send the washable items to be cleaned and sterilized.

Reverse Isolation:

• It serves as a safeguard against the contamination of a patient who already has damaged health.
• It guards against infection in cases of agranulocytosis, leukemia, lymphoma, leukopenia, anemia, immunosuppressive medication, burns, and open lesions in individuals with decreased resistance who are not infected.
• Everyone who visits a patient must wash their hands both before and after.
• Everyone will have to put on safety equipment.
• You shouldn't let somebody who is ill into the room.
• Food should not be brought into the room.
• Never exchange personal items like towels, drinking glasses, or eating utensils.

High Isolation:

• Is used to prevent the spread of unusually highly contagious or high consequence, infectious diseases (e.g. smallpox, Ebola virus).
• It requires use of: gloves, protective eyewear, a waterproof gown and a respirator at least FFP2 or N95.
• Sometimes negative pressure rooms or powered air-purifying respirators (PAPRs) are also used.

Single rooms:

In single rooms, there is less risk of an illness spreading from the originating patient to other patients.

• Amenities for cleaning hands.
• Bathrooms and restroom facilities.

An anteroom to enable the use of PPE may be included in single rooms used for isolation purposes.

Cohorting:

• If single rooms are not available for infection control reasons, patients who are infected or colonized by the same organism can be cohorted.

Isolation Rooms in Hospitals:

• Class N (negative pressure):
  • Class N rooms are used to isolate people who can spread an infection through airborne droplet nuclei.
• Class P (positive pressure):
  • Patients with impaired immune systems may be isolated in Class P rooms.

Transportation of Patients

• Restricting movement.
• When patient transport is necessary, it is important that:
  • To lessen the possibility of transmitting relevant bacteria to other patients, staff, and visitors as well as to prevent environmental contamination, the patient wears or uses appropriate barriers.
  • The personnel in the region where the patient is to be transported are informed of the patient's approaching arrival as well as the safety measures to be taken to lower the possibility of the transfer of infectious microorganisms.
  • Patients are given information on how they can help stop the spread of their contagious germs to other people. Wearing a surgical mask while in transportation is a sensible precaution when transferring a patient with active pulmonary tuberculosis.

Procedural Guidelines:

Caring for a client on isolation precautions:

• Evaluate any signs of isolation (such as recent lab results or the client's history of exposure).
• Examine the agency's policies, precautions that are required for the particular isolation system, and care procedures to be carried out inside the client's room. Avang, Ning
• Examine the nurse's notes or consult with coworkers about the client's emotional condition and isolation adjustment.
• Wash your hands before handling anything that will be brought inside the client's room.

Get ready to enter the isolation room:

• Apply a respirator or a surgical mask across the mouth and nose. (Type will vary depending on facility policies and the type of isolation.) Snugly place eyewear or goggles over your face and eyes (when needed).
• Apply the gown, making sure it encloses all outerwear. Bring sleeves to the wrists. Tie firmly around the waist and neck.
• Place disposable gloves on (note: unpowdered, latex-free gloves should be worn if the client or the health care worker has a latex allergy). Bring glove cuffs over the edge of the sleeves of the gown if gloves are worn with it.

Enter the client's room.

• Set up the tools and supplies. Place the equipment on a fresh paper towel if it will be removed from the room and used again.
• Tell the client's family why seclusion is necessary and what precautions they must take. Give people a chance to ask questions. Check for any signs of emotional issues that can be brought on by solitude.

Assess vital signs:

• Equipment stays in the room if the client is colonized or infected with a resistant organism, such as VRE (Vancomycin-resistant enterococcus). Continue to evaluate vital signs using standard protocols. Stethoscope and blood pressure cuff contact with infectious materials should be avoided.
• Use alcohol to clean the bell or diaphragm of the stethoscope before reusing it. On a spotless surface, set aside.
• Use only personal or disposable thermometers.

Administer medications:

• Dispense oral medication in a cup or a wrapper.
• Put the wrapper or the cup in a container with plastic on the inside.
• Make sure to use gloves when administering the injection.
• Put the syringe, uncapped needle, or sheathed needle, into a designated receptacle for disposal.
• If gloves are not used and hands come into touch with hazardous objects or bodily fluids, promptly wash your hands.

Administer hygiene: 

• Encouraging the customer to express any queries or worries they may have concerning isolation. Now is a good moment to adopt informal teaching methods.
• Don't let your gown become wet.
• Take the bedding off the bed; if it is overly dirty, avoid touching the gown. Put the impenetrable lines bag there.
• If gloves become excessively dirty and further care is required, change gloves and wash your hands.

Collect specimens:

• Place the specimen containers in the client's restroom on a fresh piece of paper towel.
• Observe the steps for taking a sample of bodily fluids.
• Without contaminating the container's outside, transfer the specimen to it. Put the container in a plastic bag and name it outside the bag, if necessary, in accordance with facility policies.

Dispose of linen and trash bags as they become full:

• For filthy items, use strong, moisture-resistant single bags.
• Securely tie bags at the top in a knot.
• Re-supply room as needed.

Leave isolation room.

• Don't wear gloves. By grabbing the cuff, pull one glove inside-out over the hand to remove it. Remove the glove. Put a finger into the remaining glove's cuff with your gloved hand and pull the glove off from the inside out.
• Pull the mask away from your face by joining the top and bottom strings, then dump it into a garbage can. (Avoid touching the mask's exterior surface.)
• Untie the dress's collar and waist strings. Let the robe sag off your shoulders. Without contacting the exterior of the gown, remove your hands from the sleeves. Fold the gown inside out while holding it at the shoulder seams and toss in a laundry bag.
• Take off your glasses or goggles.
• Hand washing.
• Tell the customer when you want to enter the room again. Find out whether the client needs any books, magazines, or personal care goods.
• If necessary, leave the room and shut the door. (If the client is on airborne precautions, the door should be shut.)
• All contaminated materials and tools should be thrown away in a way that stops the transmission of microorganisms to other people.
