Evaluating All Available Evidence Pertaining to Using PMDs for Pressure Injuries



Evidence leads us to knowledge of what is really happening in the world, and helps us predict what is likely to happen in the future. The Information Age allows clinicians to find research articles and conference abstracts on the internet and evaluate their content. Adding this information to our own expertise and our knowledge of individual patients (the Evidence-Based Practice triad)1 can improve practice.2,3


Guided by this question, “Does available evidence support using polymeric membrane dressings (PMDs) for pressure injuries?” the researcher searched for ALL published articles, chapters, and major conference posters (by electronically searching abstracts and walking many conference halls) which included PMDs, including those sponsored by competitors, with no date or language limits. The researcher searched PubMed and Google Scholar. Colleagues searched CINAHL and SCOPUS. The manufacturer’s records were reviewed for references. The searches are current through 31 October 2017. Documents simply mentioning the brand name in a list or table were eliminated. All other research was summarized in a table and categorized using The Joanna Briggs Institute’s Evidence Levels for Evaluating Product Effectiveness.4


Documents including pressure injuries totaled five Level I reviews, three Level I RCTs, 12 Level II Studies, five Level III studies, 45 Level IV case series/studies, seven Level V Expert Guidelines, and four Level V studies of particular relevance to pressure injury management. Authors described 934 pressure injuries managed with PMDs. The researcher found many articles and posters about which PMDs’ manufacturer was previously unaware. 105 of the 126 authors were completely independent. PMDs were found superior: they clean, balance moisture, relieve pain, and speed healing.5


Independent clinicians produce by far the majority of evidence pertaining to PMDs, including evidence pertaining to using PMDs on pressure injuries.5 The evidence demonstrates PMDs outperform conventional foams and other advanced wound management methods.5
