Barrier dressings in surgical site infection prevention strategies

Healthcare-associated infections (HCAIs) are a matter of priority for the NHS. They are associated with significant morbidity, and frequently lead to increased length of hospital stay, pain and discomfort for the patient, and in some cases even permanent disability. It is estimated that surgical site infections (SSIs) constitute around 14% of all HCAIs. Any break in the skin affords a portal of entry for microbial pathogens, and hence places the patient at an increased risk of infection. To address the issue, a multi-factorial strategy for the prevention of SSIs is essential, with postoperative dressings playing a key part alongside universal precautions such as hand hygiene and aseptic technique. The available guidance specifies the need for a postoperative dressing which provides an effective physical barrier and a moist environment for optimal wound healing. Vapour-permeable barrier dressings appear to be effective in meeting both of these criteria and also offer additional advantages both to patients and practitioners, such as patient comfort and the ability to stay in place whilst the patient showers. However, regular wound assessment must be carried out to ensure the vapour-permeable postoperative dressing is the right choice for a specific patient at a given time.
