In addition, organisations must have in place core polices in relation to the prevention and control of HCAIs, including Aseptic None Touch Technique (Department of Health 2010). 1.2 Nottinghamshire Healthcare NHS Foundation Trust (NHCT) is committed to ensuring that injury or harm to staff, patients and others by HCAIs is reduced to the lowest risk level possible. The use of Aseptic Non-Touch Technique (ANTT) during any invasive procedure, including wound care, will enable NHCT to keep HCAIs to a minimum and also allow the Trust to comply with the Health and Social Care Act 2008. 1.3 Failed aseptic technique is probably the most significant cause of preventable HCAI. However, whilst this is widely accepted, there remains a significant gap between this knowledge and the required changes in clinical behaviour. It is therefore essential that practitioners fully understand the risks they pose to patients and that this knowledge is demonstrable in practice. 1.4 Aseptic Non Touch Technique (ANTT) has been developed using research based evidence. The ANTT framework provides a standard for safe and effective aseptic practice that can be applied to all clinical procedures. 1.5 Variability in practice terms and practice definition has led to significant ambiguity in practice. ANTT avoids confusion by eliminating the use of different terminology e.g. clean or sterile technique. 2.0 U POLICY PRINCIPLES 2.1 Regardless of the setting, the aim of ANTT is always to prevent the transfer of pathogenic micro organisms from the healthcare worker, the procedure equipment or the immediate working environment, into or onto the patient. 2.2 ANTT must be used for all clinical procedures which bypass the body’s natural defenses, such as inserting or accessing intravenous (IV) indwelling devices, phlebotomy, urinary catheterisation and wound dressings. 2.3 ANTT aims to prevent microorganisms from hands, surfaces or equipment being introduced into a susceptible (key) site such as an intravenous device, urinary catheter or wound, by identification and protection of the key parts of any procedure. 3.0 3.1 U U DUTIES Chief Executive • The Chief Executive has overall responsibility for ensuring that there are effective arrangements in place for Infection Prevention and Control (IPC) within the Trust to meet all statutory requirements. ISSUE 3 – JUNE 2015 2 Aseptic Non Touch Technique – 18.14 3.2 E xecutive Director for Nursing, Quality and Patient Experience U • 3.3 U The Executive Director for Nursing, Quality and Patent Experience is the Director for Infection Prevention and Control (DIPC). The DIPC will provide assurance to the Trust Board that effective systems are in place to reduce the risks of HCAIs. Managers Managers are responsible for ensuring that: 3.4 • All staff have access to IPC policies to support their daily working practice. • All staff attend IPC training in accordance with the organisation’s statutory and essential training matrix • An ANTT competency framework is in place • All staff achieve competency in carrying out procedures involving ANTT U Infection Prevention and Control Team • 3.5 U The IPC Team is responsible for updating the policy and providing advice and information on ANTT All Staff The clinicians providing services to the patient are responsible for: 4.0 • Ensuring that they are able to access IPC Policies • Attending relevant training. • Ensuring that they achieve and maintain competency in relation to ANTT practice U DEFINITIONS 4.1 Asepsis- is the absence of bacteria, fungi, viruses or other micro-organisms that could cause disease 4.2 Aseptic technique - defines the infection prevention method and precautions taken during invasive clinical procures to prevent the transfer of microorganisms from the healthcare worker, procedure equipment or the immediate environment to the patient. 4.3 Aseptic Non Touch Technique - a specific type of aseptic technique with a unique Theoretical and Clinical Practice Framework based upon the original concept of Key-Part and Key-Site Protection where staff identify and protect key parts and key sites (Rowley 2011) 4.4 Key Part – the critical part of equipment that comes into contact with a key site. 4.5 Key site- a part of the body that is at risk of contamination if ANTT is not used e.g. wound, urethral meatus, insertion and access sites for medical devices. 4.6 Aseptic field- a designated aseptic working space that contains and protects the procedure equipment from direct and indirect environmental contact-contamination by microorganisms. (See aseptic field types below.) ISSUE 3 – JUNE 2015 3 Aseptic Non Touch Technique – 18.14 4.7 General Aseptic Field – the main aseptic field that promotes asepsis during procedures by providing basic protection from the procedure environment. Used when key parts can easily and efficiently be protected by micro critical aseptic fields e.g. caps and covers during intravenous therapy and phlebotomy. 4.8 Critical Aseptic Field – the main aseptic field that ensures asepsis during procedures by the use of a sterile field which protects the procedure environment. E.g. urinary catheterisation, complex wound care, surgical procedures 5.0 U 5.1 PRINCIPLES OF ANTT The Key principles of ANTT are: A – Always ensure hands are decontaminated effectively prior to the procedure N – Never contaminate key parts of sterile materials/equipment or the patient’s susceptible key sites T – Touch non-key parts with confidence T –Take appropriate infection prevention and control precautions e.g. PPE, waste 5.2 U Hand Hygiene - The 5 Moments of Hand Hygiene 5.2.1 The patients immediate care environment should be managed at all times according to the World Health Organisation’s (WHO) model, The Five Moments of Hand Hygiene (Sax et al 2007). The model is designed to protect the patient and the patient’s environment by effective and timely hand hygiene, reducing the potential for environmentally influenced contamination of invasive aseptic procedures. 5.2.2 There are 5 recognised crucial points of care for hand hygiene, representing the time and place at which there is the highest likelihood of transmission of infection via the hands of healthcare staff (World Health Organisation 2006). • • • • • 5.3 U Personal Protective Equipment 5.3.1 5.4 Before patient contact Before an aseptic task After body fluid exposure risk After patient contact After contact with patient surroundings (Refer to Hand Hygiene Policy Appendices 2a and 2b) Each procedure should be risk assessed to determine the level of exposure to blood and bodily fluid splashing. Single use gloves and plastic aprons should always be worn where there is a risk of contact with blood or bodily fluids. If a key part has to be handled or a key site touched, then the gloves must be sterile e.g. urinary catheterisation. Eye and face protection may be required if the procedure has a risk of splashing blood or bodily fluids to the face. (Please refer to the policy for Correct use of personal protective equipment in the clinical setting. 18 20). Aseptic non touch technique must be used for all clinical procedures which bypass the body’s natural defences such as: • • • • Inserting or accessing IV indwelling devices and on going care Administering IV medicines and parenteral nutrition Urinary catheterisation and urine sampling via catheter port When dressing wounds healing by primary intention (before surface skin has sealed), e.g. surgical wounds, burns, lacerations/breaks in the skin, ulcerations. ISSUE 3 – JUNE 2015 4 Aseptic Non Touch Technique – 18.14 • • • • Application of dressings to wounds healing by secondary intention e.g. leg ulcers, pressure sores. Enteral feed connection Surgical procedures, e.g. Minor Surgery, biopsies Phlebotomy This list is not exhaustive and health care workers will need to identify the key and non key parts prior to commencing care for all invasive procedures. 5.5 5.6 6.0 The overriding principle of ANTT is that the susceptible key site and key parts should not come into contact with any non-sterile items. A key part is a component that if contaminated with micro-organisms increases the risk of infection. When handling sterilised equipment, only the part of the equipment not in contact with the susceptible key site is handled. All staff must ensure their actions minimise the likelihood of potentially pathogenic microorganisms being introduced into the patients’ susceptible key site and being spread between patients and colleagues. U KEY STAGES OF ANTT 6.1 Different clinical procedures present different levels of complexity. Therefore, in order to be efficient as well as safe, any practice framework for aseptic technique must define what type of aseptic technique and precautions are required for both simple and complex procedures, and how to decide between the two approaches. 6.2 In ANTT, uncomplicated and complex approaches to technique are termed StandardANTT and Surgical-ANTT respectively. It is important to note that the two approaches adhere to exactly the same ‘ANTT-Approach’. 6.3 The main difference between Standard and Surgical-ANTT is the type and management of aseptic field(s) depending on the number of Key- Parts and Key-Sites that require protection. 6.4 6.5 U Standard-ANTT • Standard-ANTT is the technique of choice when procedures meet all of the following criteria: They involve minimal Key-Parts and small Key-Parts, are not significantly invasive, are technically uncomplicated to achieve asepsis and are short in duration • Standard ANTT requires the use of a general aseptic field i.e. a clean surface or tray on which to place equipment with key parts protected e.g. caps and covers U Surgical-ANTT • 6.6 U Surgical-ANTT is demanded when procedures meet one or more of the following criteria: They involve large or numerous Key-Parts, are significantly invasive, (e.g. Large Key-Sites(s) or central venous access), are technically complex to achieve asepsis or involve extended procedure time. Surgical ANTT requires the use of a critical aseptic field e.g. sterile procedure pack Standard and Surgical Procedure Duration • The longer Key-Parts and Key-Sites are exposed to the environment, the greater the potential for environmental or inadvertent touch contamination. Key parts therefore must remain protected at all times until the point of use e.g. by leaving the sterile packet on a urethral catheter until the point of insertion or caps and covers on syringes. ISSUE 3 – JUNE 2015 5 Aseptic Non Touch Technique – 18.14 6.8 U Preparation of the Patient • 6.8 6.9 6.10 U U Inform the patient about the procedure, gain consent and make them comfortable. There should be adequate means to protect the patient’s dignity. Unnecessary exposure of vulnerable sites should be avoided. Preparation of the Environment 6.8.1 The ideal environment for ANTT procedures is a designated clinic room. Where this is impractical, clinical procedures performed at the patients’ bedside must not occur directly after activities such as bed making, which may contribute to airborne contamination 6.8.2 Windows must be kept closed and portable air conditioning units or fans turned off during the clinical procedure. 6.8.3 The immediate environment should be clean and free from visible dirt and dust. 6.8.4 Assess the need for standard or surgical ANTT and gather the appropriate equipment 6.8.5 The trolley/tray/surface on which equipment and dressings are placed for procedures must be thoroughly cleansed with detergent and water, dried and then disinfected with disinfectant wipes or spray. Alternatively, multi purpose wipes which both cleanse and disinfect can be used. The surface must be thoroughly dried afterwards. If a dressing trolley is used it should be designated for this purpose only. 6.8.6 Sterile packs should be checked for expiry dates and to ensure there is no evidence of damage or moisture penetration. U Preparation of Staff 6.9.1 Staff must be bare below the elbow (see Hand Hygiene Policy 18.04) and must ensure that any cuts or abrasions on their hands or forearms are covered with a waterproof occlusive dressing. 6.9.2 Uniforms/ clothing should be protected with a disposable plastic apron if there is a risk of contamination with pathogenic organism or blood and body fluids. The apron should be changed for each patient prior to commencing an aseptic procedure or between different procedures on the same patient. U Performing the Procedure U 6.10.1 Use a non touch technique at all times. 6.10.2 Sterile packs must be opened carefully to prevent contamination of contents. 6.10.3 Identify Key parts and remove equipment from the packaging carefully 6.10.4 Assemble all equipment and arrange in an organised manner in the aseptic field ensuring that key parts are protected at all times with caps, covers etc. Key parts should NEVER be touched as doing so will compromise the aseptic technique. 6.10.5 Ensure that sterile items do not come into contact with unsterile objects and only sterile items come into contact with the susceptible key site. For example when ISSUE 3 – JUNE 2015 6 Aseptic Non Touch Technique – 18.14 touching a syringe with a needle, staff may handle the syringe but not the needle as this is a key part. 6.10.6 If a key part has to be handled or a key site touched, then sterile gloves must be worn e.g. urinary catheterisation. 6.10.7 Following the clinical procedure gloves and other personal protective equipment must be removed and disposed of appropriately and hands decontaminated. 6.10.8 The clinical procedure which has been undertaken must be documented in the patient’s health care records. Following access of indwelling devices staff must always document the condition of the insertion and exit sites. 7.0 U ANTT IN COMMUNITY SETTINGS 7.1 The environment within some community settings such as the patients’ homes, GP practice, schools, etc. may not always be favourable for carrying out clinical practice. The healthcare worker may not have access to adequate hand washing facilities, trolleys, or other equipment and standards of environmental cleanliness cannot always be guaranteed. However, the healthcare worker is responsible for ensuring that the environment allows the procedure to be carried out safely and minimises any identified risks. A clean surface where available i.e. table or tray should be used to arrange the necessary equipment. Where this is not possible the sterile field in the dressing pack should be used and placed as near to the patient as possible but away from the patient’s immediate vicinity i.e. not placed on a bed next to the patient or on the floor, to avoid the risk of contamination. Best practice would be for staff to be provided with wipable plastic trays for carrying out ANTT. 7.2 Pets should be kept away from the environment during the procedure. 7.3 Items of medical equipment should be stored in a designated box/bag away from the floor. 7.4 Where spare non sterile gloves and aprons are required and are decanted into another bag/container from their original box/packaging, the clinician undertaking this practice must have decontaminated their hands effectively first. This is to prevent contamination from the hands to the personal protective equipment. 7.5 Gloves and aprons should not be kept in clinicians pockets. 7.6 Decontamination of Hands-. All staff on domiciliary visits should be supplied with liquid soap, paper towels, alcohol hand rub & hand cream. (Refer to Hand Hygiene Policy 18.04) 8.0 U ANTT CLINICAL GUIDELINES 8.1 ANTT Clinical Guidelines, available from the Association of Safe Aseptic Practice (ASAP) have been formulated to standardise common clinical invasive procedures. These guidelines aim to reduce practice variability and to ensure that hand decontamination occurs at appropriate times during the ANTT procedure. They also aim to ensure that susceptible key sites and key parts are protected at all times by using a non-touch technique. 8.2 The collections of Hospital and Community Care focussed ANTT Clinical Guidelines and associated audit tools are provided freely on request by the Association for Safe Aseptic Technique (ASAP). ISSUE 3 – JUNE 2015 7 Aseptic Non Touch Technique – 18.14 9.0 9.1 10.0 U IMPLEMENTATION U The responsibility for implementing this policy rests with the manager responsible for each individual or group of staff. Managers are required to ensure that all staff are aware of the policy and are able to practice in accordance with the requirements of this. U TRAINING 10.1 The Health and Social Care Act 2008 (Department of Health 2010) states that the principles and practice of prevention and control of infection is included in an induction training programme for new staff and as part of on going education for existing staff. Information on standard infection prevention and control principles relevant to this policy are included in the Trust induction and mandatory training sessions. 10.2 All staff involved in carrying out invasive procedures must receive training in ANTT and be deemed competent. 10.3 The IPC Team can deliver additional training on the content of this policy where necessary. 11.0 11.1 12.0 U TARGET AUDIENCE The target audience for this policy is all staff involved in invasive procedures.

Introduction The Health and Social Care Act (2008): Code of Practice for the prevention and Control of Healthcare Associated Infections (HCAI) stipulate that all organisations must have in place a Aseptic None Touch Technique policy (ANTT) (Department of Health 2010). The use of ANTT during any invasive procedure, including wound care, will enable Nottinghamshire Healthcare Trust to prevent unnecessary harm and keep HCAIs to a minimum. Failed aseptic technique is probably the most significant cause of preventable HCAI. It is therefore essential that practitioners fully understand the risks they pose to patients and that this knowledge is demonstrable in practice. ANTT has been developed using research based evidence. The ANTT framework provides a standard for safe and effective aseptic practice that can be applied to all clinical procedures. Patients with lower leg ulceration often experience excess wound exudate can affect the surrounding skin causing maceration and excoriation and delay healing. Dead skin can build up between toes, becoming macerated and lead to fungal or bacterial infection. To prevent these problems cleansing the lower limb will remove the build-up of exudate, slough and dead skin without damaging granulation or epithelialising tissue. Removal of dry, loose tissue allows the growth of new epithelium and aims to prevent hard areas of tissue, scabs and hyperkeratosis from building up which can act as pressure point beneath dressings and compression therapy. U 2. Options for the cleansing of lower legs As well as assisting with the healing of the lower leg wounds, the cleansing of the leg is often welcomed by patients who experience difficulty bathing. There are a number of methods available for the cleansing of lower legs as follows: Debriding products The use of a debriding product such as Debrisoft can be used with saline or warm tap water to remove exudate, slough and dry skin. This product is recognised by NICE (2012) and promotes the principles of ANTT as it is a sterile, single use product. U Washing -Leg washing sinks The use of a dedicated leg washing sink with a shower hose is the preferred method for washing lower legs in a clinic setting. This method of washing the leg in running water will prevent the risk of wound colonisation which may occur when legs are submerged in a bucket of water. U ISSUE 3 – JUNE 2015 10 Aseptic Non Touch Technique – 18.14 NB. If using a leg washing sink, the sink should be cleaned after each leg has been cleansed. Refer to the Infection Prevention and Control local procedure for decontaminating leg washing sinks. -Leg washing buckets The use of leg washing buckets must only be considered when the above is not an option e.g. where there is no access to a leg washing sink or access is difficult for the patient. Buckets should be clean and lined with a plastic liner. They must be washed, dried and stored appropriately after use. After the leg has been cleansed, the wound dressing must be carried out in line with ANTT. 3.
