Foot ulcers in people with diabetes are a prevalent and serious global health issue. Dressings form a key part of ulcer treatment, with clinicians and patients having many different types to choose from. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use.
The review aimed to evaluate the effects of foam wound dressings on the healing of foot ulcers in people with diabetes.
We searched the Cochrane Wounds Group Specialised Register (searched 10 June 2011); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 2); Ovid MEDLINE (1950 to June Week 1 2011); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, 8 June, 2011); Ovid EMBASE (1980 to 2011 Week 22); EBSCO CINAHL (1982 to 3 June 2011). There were no restrictions based on language or date of publication.
Published or unpublished randomised controlled trials (RCTs) that evaluated the effects on ulcer healing of one or more foam wound dressings in the treatment of foot ulcers in people with diabetes.
Data collection and analysis
Two review authors independently performed study selection, risk of bias assessment and data extraction.
We included six studies (157 participants) in this review. Meta analysis of two studies indicated that foam dressings do not promote the healing of diabetic foot ulcers compared with basic wound contact dressings (RR 2.03, 95%CI 0.91 to 4.55). Pooled data from two studies comparing foam and alginate dressing found no statistically significant difference in ulcer healing (RR 1.50, 95% CI 0.92 to 2.44). There was no statistically significant difference in the number of diabetic foot ulcers healed when foam dressings were compared with hydrocolloid (matrix) dressings. All included studies were small and/or had limited follow-up times.
Currently there is no research evidence to suggest that foam wound dressings are more effective in healing foot ulcers in people with diabetes than other types of dressing however all trials in this field are very small. Decision makers may wish to consider aspects such as dressing cost and the wound management properties offered by each dressing type e.g. exudate management.
Plain language summary
Foam dressings for healing foot ulcers in people with diabetes
Diabetes, a condition which leads to high blood glucose concentrations, is a common condition with around 2.8 million people affected in the UK (approximately 3% of the population). Dressings are a widely used treatment when caring for foot ulcers in people with diabetes. There are many types of dressings that can be used, which also vary considerably in cost. Existing reviews have not found evidence that one dressing type is more effective than other types in healing foot ulcers in people with diabetes. This review (157 participants) confirms that currently there is no research evidence to suggest that foam wound dressings are more effective in healing diabetic foot ulcers than other types of dressing. Current decisions on choice of wound dressing if any, should be based where possible, on dressing costs and selecting the most useful management properties offered by each dressing type, for example, the management of wound discharge.
