For instance a case of influenza in a normal household setting does not require strict precautions, where as one in a long term care home might.

Precautions will vary according to the microorganism involved and the context of the case. (See Table) If the mode of transmission is known, precautions can be put in place to prevent outbreaks. There are six common modes of transmission of infection. Wear gloves, mask, and apron when needed.īy doing these things, you may stop an infection either to you or your care. Keep clothing clean by holding things away from you.

Portal of exit: Cover mouth and nose when coughing or sneezing.

You can stop the process by ‘breaking’ the chain and removing one of the links. Elderly people are more susceptible due to aging changes.

Susceptible Host: Someone more likely to become infected.

Examples – cuts, mucous membranes (eyes, nose, mouth).

Portal of Entry: How pathogen enters new place or host.

Examples – hands, food, mouth, and clothing.

Transmission: How pathogen is carried from portal of exit to portal of entry.

Examples – drainage & secretions, urine, stool, blood, breathing, sneezing, or coughing.

Portal of exit: How pathogen leaves one place or host.

Examples – cut or open area, bladder, and lungs.

Reservoir: Where the pathogen lives and grows usually in warm, moist, dark places.

Pathogen: Microorganism that causes disease.

It is best explained by looking at the ‘chain of infection’ which consists of six ‘links’ that have to be present for an infection to happen. Whether or not an infection happens will depend on a number of things. Surgical and medical aseptic techniques encompass similar strategies such as hand hygiene but with distinct differences.Chain of infection, Infective process.

Insertion and maintenance of invasive devices are guided by published evidenced-based recommendations supporting education, training, and standardized care for patients with central lines, surgical sites, ventilators, and urinary catheters.

Clean technique leads to a decrease of the overall number of microorganisms present rather than the absence of microorganisms as is found in surgical asepsis.Ref 30-3 Yokoe DS, Mermel LA, Anderson DJ, et al. Clean technique, or medical asepsis, is another practice to prevent or reduce the risk of transmission of organisms from one person to another or from one place to another. Situations in which surgical asepsis technique is applied include surgery as well as other areas where invasive procedures are done such as placement of intravenous lines, urinary catheters, chest tubes, and any other indwelling devices.

Guideline for hand hygiene in health-care settings: Recommendations of the Healthcare Infectio. You do not have permission to view this object.Īseptic technique improves patient safety and prevents healthcare-associated infections that may negatively impact outcomes including: increasing patient morbidity and mortality, increasing healthcare costs for patients and their families, prolonging length of stay, increasing resistance of microorganisms to antimicrobials, and increasing physical and mental discomfort for the patient.Ref 30-2 Centers for Disease Control and Prevention. Following observations of Ignaz Semmelweis and others over 100 years ago, the practice of aseptic technique is an infection prevention method that is recognized as an important factor in the prevention and transmission of healthcare-associated infections.Ref 30-1 Association of Perioperative Registered Nurses (AORN).
