Medical asepsis refers to a clean technique to prevent and reduce the number of microorganisms. There are two main types of asepsis, medical and surgical. ANTT has been endorsed by the Department of Health EPIC 3 guidelines (Pratt et al 2014). the absence of pathogenic organisms or toxins from the blood or tissues (Wilson 1995). The aim of using ANTT is to prevent the introduction of micro – organisms into susceptible body sites (Rowley 2001). There is agreement in the literature that one of the most effective ways of reducing HCAI’S is through the application of a standardised ANTT for a clinical procedure (Rowley 2003, Pratt et al 2014). Patients suffer harm or may die as a result of Healthcare associated infections (HCAI’S).

Identifying the ‘key parts’ and ‘key sites’ of a procedure and not touching them either directly or indirectly. It defines the infection prevention method and precautions taken during invasive clinical procedures to prevent the transfer of microorganisms from the healthcare worker, procedure equipment or the immediate environment to the patient. Should be used during any procedure that bypasses the body’s natural defences.

The ANTT framework is based upon the goal of asepsis rather than sterility and the approach is gauged on the technical difficulty of each procedure rather than the diagnosis or age of the patient. This standardised approach, developed in University College Hospital (UCH) London, has been shown to significantly improve the aseptic technique of healthcare workers and reduce the numbers of Healthcare Associated Infections (HCAIs).ĪNTT is a core nursing and medical skill that defines the infection prevention and control methods and precautions necessary during invasive clinical procedures to prevent the transfer of microorganisms to ‘key’ or sterile body sites from healthcare professionals, procedure equipment or the immediate environment to a patient.
