The use of protective clothing is an essential element of infection prevention and control. Many items of protective clothing are incorporated within the concept of universal precautions - the precautions necessary to reduce exposure to blood or body fluids (Centre for Disease Prevention and Control, 1987). Protective clothing is also used to prevent the transmission of micro-organisms other than blood-borne viruses - for example, methicillin-resistant Staphylococcus aureus, Staphylococcus aureus and Mycobacterium tuberculosis.
Studies have shown that there is no consistent approach towards the use of protective clothing and confusion as to which item to wear and when (McCoy et al, 2001). This may leave health care workers or patients at risk of acquiring an infection. Therefore practical, evidence-based guidelines for the use of protective clothing are needed in order to promote best practice.
Summary of the guidelines Protective Clothing: Principles and Guidelines (Infection Control Nurses' Association, 2002), clearly states its aims as follows:
- To emphasise the importance of protective clothing as an essential component in reducing cross infection;
- To challenge the ritualistic use of protective clothing by promoting evidence-based practice.
To achieve these aims the contents of the guidelines focus on the use of gloves, gowns, aprons, masks, goggles, visors, caps and theatre footwear.
Explained in the introductory chapter are the principles of risk management, health and safety legislation and the professional duty of care used to underpin the guidelines. Each section thereafter discusses the evidence for use and the function of the item of protective clothing in relation to the prevention of cross-infection as well as problems that may be encountered when using them.
The section on glove use, for example, identifies key aims to be met from the use of gloves. After giving a brief history of their use it goes on to identify the process of risk assessment, necessary in order to select the correct glove material, size, a sterile or non-sterile glove and whether there is a need to double-glove. A useful summary of latex allergy is also provided, indicating when and where to seek advice if this is suspected.
By discussing the appropriate use of protective clothing and relating its use to risk assessment and available evidence or expert opinion the authors attempt to tackle ritualistic practice. The role of theatre gowns in isolation is discussed, and it is recommended that they should not be used where plastic aprons will suffice.
Confusion is common where there is more than one purpose for an item of protective clothing or several different versions of it. This is often the case in the use of masks. These guidelines tackle this issue by clearly outlining the reasons for wearing masks and how the evidence, which often seems contradictory, has influenced this practice.
The shift in emphasis from masks to protect patients in the surgical setting to masks that protect the scrub team is explained. The traditional practice of wearing masks for isolation of patients is also addressed, in particularly when caring for patients with pulmonary tuberculosis.
Many items of protective clothing, despite being manufactured for single use, have been ritually re-used. Where relevant, these guidelines strongly emphasise the importance of single use.
Implications for practice Where practice is ritualistic it is probable that there will be resistance to changes. Therefore a strategy of change management will be necessary to guide the process. Monitoring the adherence to the guidelines will be an important aspect of the evaluation of the change, where liaison with clinical audit departments or the use of a link nurse system may be required.
A key method of dissemination will be through education on the correct use of protective clothing and the need for changes in practice. Traditional approaches towards the education of health personnel in infection control practice has had limited success (Davis-Beattie and de Wit, 1996). Therefore, methods of education need to be carefully planned, innovative and dynamic to be successful at meeting the needs of the diverse groups of health care workers (Rao et al, 2002). The inclusion in the guidelines of teaching material will assist the process of planning educational aims, objectives and content.
Ritualistic practices can be costly - so can health care-associated infection (Plowman et al, 2000). The ritual use of some items of protective clothing can result in over-use. This can lead to reluctance to introduce new or additional items of protective clothing, fearing their improper use. Moreover, the potential for litigation may be increased as health care-associated infection, in health care workers or patients, can result in large compensation claims. The recommendations from these guidelines will assist in preparing cost-benefit analysis when planning the introduction of items of protective clothing in clinical use.
