Transmission-based precautions are used when the route(s) of transmission is (are) not completely interrupted using standard precautions alone. There are four categories of transmission-based precautions: contact precautions, enhanced barrier precautions, droplet precautions, and airborne precautions. For patients with these types of pathogens, standard precautions are used along with specific transmission-based precautions. Epidemiologically important pathogens include, but are not limited to, Coronavirus disease (COVID-19), Clostridium difficile (C-diff), Methicillin-resistant staphylococcus aureus (MRSA), Vancomycin-resistant enterococci (VRE), Respiratory syncytial sirus (RSV), measles, and tuberculosis (TB). In addition to standard precautions, transmission-based precautions are used for patients with documented or suspected infection, or colonization, of highly transmissible or epidemiologically important pathogens. Aseptic technique for invasive nursing procedures such as parenteral medication administration Įach of these standard precautions is described in more detail in the following subsections.Sharps safety (i.e., engineering and work practice controls).Proper handling and cleaning of environment, equipment, and devices.Appropriate patient placement and care using transmission-based precautions when indicated. ![]()
