Hydrocolloid dressings for healing diabetic foot ulcers.Cochrane Database Syst Rev 2013; (8):CD009099CD
Foot ulcers in people with diabetes are a prevalent and serious global health issue. Wound dressings are regarded as important components of ulcer treatment, with clinicians and patients having many different types to choose from including hydrocolloid dressings. There is a range of different hydrocolloids available including fibrous-hydrocolloid and hydrocolloid (matrix) dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use.
To compare the effects of hydrocolloid wound dressings with no dressing or alternative dressings on the healing of foot ulcers in people with diabetes.
For this first update, in April 2013, we searched the following databases the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. There were no restrictions based on language or date of publication.
Published or unpublished randomised controlled trials (RCTs) that have compared the effects on ulcer healing of hydrocolloid with alternative wound treatments in the treatment of foot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 five studies (535 participants) in the review: these compared hydrocolloids with basic wound contact dressings, foam dressings, alginate dressings and a topical treatment. Meta-analysis of two studies indicated no statistically significant difference in ulcer healing between fibrous-hydrocolloids and basic wound contact dressings: risk ratio 1.01 (95% CI 0.74 to 1.38). One of these studies found that a basic wound contact dressing was more cost-effective than a fibrous-hydrocolloid dressing. One study compared a hydrocolloid-matrix dressing with a foam dressing and found no statistically significant difference in the number of ulcers healed. There was no statistically significant difference in healing between an antimicrobial (silver) fibrous-hydrocolloid dressing and standard alginate dressing; an antimicrobial dressing (iodine-impregnated) and a standard fibrous hydrocolloid dressing or a standard fibrous hydrocolloid dressing and a topical cream containing plant extracts.
