Hydrocolloid vs Gauze Dressings in Treating Pressure Ulcers
A search of PubMed and Web of Science, from their inception to May 25, 2013, included the terms "hydrocolloid dressing," "gauze dressing," and "pressure ulcer." The search detail in PubMed was hydrocolloid [TW] AND gauze [TW] AND "Pressure Ulcer" [MeSH]. In Web of Science citation database, the authors selected the Science Citation Index Expanded (SCI-EXPANDED) and Conference Proceedings Citation Index Science (CPCI-S) databases. The search detail used was as follows: TS = hydrocolloid AND Topic (TS) = gauze AND TS = "pressure ulcer." The authors supplemented the searches by manually reviewing the references of all relevant studies. No language restrictions were applied on these searches.
The inclusion criteria included the following: only RCTs were included; patients had a stage I-IV pressure ulcer; hydrocolloid dressing vs gauze dressing was used in the treatment of pressure ulcers; complete wound healing rate and reduction in wound volume or surface area was achieved. Case reports, case series, single arm phase I trials, retrospective case-control studies, and phase II nonrandomized trials were excluded.
Study quality was evaluated using the Jadad scale which offers a score ranging from 1–5 based on the following parameters: randomization (2), double-blinding (2), and withdrawals/dropouts at follow-up (1). A final score of 1–2 is defined as low quality and 3–5 as high quality. Two reviewers independently assessed the quality of each included study, and disagreements were resolved by discussion.
A standard form was used to extract data on first author, year of publication, country and setting in which the study was carried out, number of patients, age, pressure ulcer severity, duration of treatment, complete wound healing rate, and reduction in wound in 2 groups, respectively.
