Input: We found 13 eligible systematic reviews relevant to this overview that contained a total of 17 relevant RCTs. One review reported the results of a network meta-analysis and so presented information on indirect, as well as direct, treatment effects. Collectively the reviews reported findings for 11 different comparisons supported by direct data and 26 comparisons supported by indirect data only. Only four comparisons informed by direct data found evidence of a difference in wound healing between dressing types, but the evidence was assessed as being of low or very low quality (in one case data could not be located and checked). There was also no robust evidence of a difference between dressing types for any secondary outcomes assessed. There is currently no robust evidence for differences between wound dressings for any outcome in foot ulcers in people with diabetes (treated in any setting). Practitioners may want to consider the unit cost of dressings, their management properties and patient preference when choosing dressings.
Output:

This overview drew together and summarised evidence from 13 systematic reviews that contained 17 relevant randomised controlled trials (the best type of study for this type of question) published up to 2013. Collectively, these trials compared 10 different types of wound dressings against each other, making a total of 37 separate comparisons. The different ways in which dressing types were compared made it difficult to combine and analyse the results. Only four of the comparisons informed by direct data found evidence of a difference in ulcer healing between dressings, but these results were classed as low quality evidence. There was no clear evidence that any of the 'advanced' wound dressings types were any better than basic wound contact dressings for healing foot ulcers. The overview findings were restricted by the small amount of information available (a limited number of trials involving small numbers of participants). Until there is a clear answer about which type of dressing performs best for healing foot ulcers in people with diabetes, other factors, such as clinical management of the wound, cost, and patient preference and comfort, should influence the choice of dressing. This plain language summary is up-to-date as of April 2015.
