Abstract

Topical silver agents and dressings are used to control infection and promote healing in chronic wounds, but reviews published from 2006 to 2011 found heterogeneous results regarding their effectiveness. A scoping review was conducted to examine the extent, range, and nature of research activity surrounding chronic wound care that employed silver-impregnated dressings; identify research gaps in the existing literature; and summarize the evidence to provide recommendations for future clinical studies. Ten (10) electronic databases and additional sources were screened from their inception to May 2016; search terms for the different databases included but were not limited to silver, chronic, complications, wound, ulcer, and sore. English-language articles that compared silver dressings with an alternate treatment in adults with chronic wounds and that reported clinical outcome measures were included. Of 222 full-text reviewed studies, 27 were included for qualitative analysis. Qualitative analysis was guided by key findings identified among the included studies that were analyzed in aggregate form where appropriate. In comparative analyses of the 26 studies that investigated wound healing, 15 revealed significantly positive wound healing outcomes with silver treatments versus 9 that did not; the remaining 2 failed to provide statistical values of significance. Of 17 studies that presented data on microbiology, 3 reported significant microbial load improvement for silver dressings, 9 noted nonsignificant findings, and 4 provided no statistical values. Pain, adverse events, and treatment cost were included in 5, 7, and 3 studies, respectively, with heterogeneous findings. The heterogeneous evidence regarding the impact of silver dressings on clinical outcomes may be related to differences in the silver treatments themselves, heterogeneous intervention strategies, study designs, outcomes, and measures. Well-designed clinical studies with multiple outcome parameters are necessary to determine the optimal type and use of silver-dressings in chronic wounds.
