Historical and contemporary literature presents a confused hierarchy of terms and practices including sterile technique, aseptic technique, clean technique and non-touch technique, further compounded by interchangeable use and meaning (Aziz 2009 Rowley et al. Although the prescription for aseptic technique is universal, agreement on the aim, definition, description and application of aseptic technique is not (Preston 2005 NICE 2012 Gorski et al. In terms of protecting patients from infection, aseptic technique is one of the most important and commonly used critical clinical competencies in healthcare. A combination of decontamination processes, sterilized equipment and handling technique is used to minimize potential transmission of pathogenic microorganisms (Clare and Rowley 2017). KeywordsĪt its heart, aseptic technique involves a collection of infection prevention actions designed to protect patients from infection when undergoing invasive clinical procedures, including maintenance of indwelling medical devices. This chapter provides clinical examples of how the ANTT ® is implemented in the healthcare setting, as well as, importantly, how to promote compliance of the technique. During the insertion or manipulation of an intravascular device, the ‘ANTT-Approach’ provides a systematic method that supports the practitioner to include all the important elements of aseptic technique, with particular focus on the identification and protection of ‘Key-Parts’ and ‘Key-Sites’ throughout the preparation and the procedure. The ANTT ® Clinical Practice Framework provides a comprehensive framework for aseptic technique for all invasive procedures based on an approach termed Key-Part and Key-Site Protection. The Aseptic Non Touch Technique (ANTT ®), originated by Rowley in the late 1990s, was designed to help address variable aseptic technique standards of practice and provide a rationalized, contemporary, evidence-based framework to standardize this critical competency and help improve standards of practice. However, no meaningful explanation of what aseptic technique is or how it is to be applied to ensure patient safety is provided within any of the guidelines. Surgical and medical aseptic techniques encompass similar strategies such as hand hygiene but with distinct differences.Aseptic technique, which involves infection prevention actions designed to protect patients from infection when undergoing invasive clinical procedures, is universally prescribed by guideline makers as a critical competency in the prevention of infections. 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.

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).
