I. Introduction
Isolation precautions, also known as infection control measures, are critical for reducing the spread of infectious diseases. They are essential in any health care setting, and form the basis of infection prevention and control. The seven categories of isolation precautions are Standard Precautions, Contact Precautions, Droplet Precautions, Airborne Precautions, Protective Environment, Sterile Technique, and Vector Precautions.
II. Standard Precautions
Standard Precautions are a set of infection control practices that apply to all patient care, regardless of suspected or confirmed infection status of the patient. They include hand hygiene, the use of personal protective equipment (such as gloves, masks, and gowns), respiratory hygiene, safe injection practices, and safe disposal of sharp items. Standard Precautions are the foundation of infection prevention and control, and should be used for all patient encounters.
III. Contact Precautions
Contact Precautions are designed to reduce the risk of transmission of infectious agents from direct or indirect contact with the patient or their environment. They include the use of gloves and gowns for all patient contact, as well as environmental cleaning and patient placement measures. Contact Precautions are used for patients with certain communicable diseases, such as C. difficile, MRSA, and VRE.
IV. Droplet Precautions
Droplet Precautions are designed to reduce the risk of transmission of infectious agents through the airborne route from large-particle droplets. They include the use of a surgical mask for any patient contact, as well as environmental cleaning and patient placement measures. Droplet Precautions are used for patients with certain communicable diseases, such as influenza, pertussis, and meningitis.
V. Airborne Precautions
Airborne Precautions are designed to reduce the risk of transmission of infectious agents through the airborne route from small-particle aerosols. They include the use of a respirator (N95 or higher) for any patient contact, as well as environmental cleaning and patient placement measures. Airborne Precautions are used for patients with certain communicable diseases, such as tuberculosis and varicella.
VI. Protective Environment
A Protective Environment is a special room or area where patients are placed under airborne isolation precautions. It is designed to reduce the risk of transmission of infectious agents through the airborne route from small-particle aerosols. A Protective Environment includes the use of a respirator (N95 or higher) for any patient contact, as well as environmental cleaning and patient placement measures.
VII. Sterile Technique
Sterile technique is a set of infection control practices used during medical and surgical procedures to reduce the risk of contamination and transmission of infectious agents. It includes the use of sterile gloves, gowns, and other protective clothing; sterile drapes; and sterile equipment and supplies.
VIII. Vector Precautions
Vector Precautions are designed to reduce the risk of transmission of infectious agents from vectors, such as ticks, mosquitoes, and fleas. They include the use of insect repellents, protective clothing, and environmental measures. Vector Precautions are used for patients with certain communicable diseases, such as Lyme disease and West Nile virus.
