A pragmatic randomised controlled clinical study to evaluate the use of silicone dressings for the treatment of skin tears

Abstract

One of the most common types of skin breakdown in ageing populations is skin tears. The International Skin Tear Advisory Panel advocates for special attention to be paid to dressing selection related to skin tear management. The panel recommends choosing dressings that will promote the maintenance of moisture balance, suit the local wound environment, protect peri-wound skin, control or manage exudate and infection, and optimise caregiver time. It is paramount that dressings protect the fragile nature of the skin associated with those who at heightened risk for skin tear development. To compare the effectiveness of soft silicone dressings (a contact layer and/or foam) for the healing of skin tears with local practices that do not include soft silicone dressings. The study was a pragmatic randomised controlled prospective study. One hundred and twenty-six individuals from two long-term care facilities in Ontario Canada who presented with skin tears were randomised into the treatment group using either soft silicone dressings (a contact layer and/or foam) or the control group using non-adhesive dressings. The current study demonstrated that 96.9% (n = 63) of skin tears in the treatment group healed over a 3-week period compared with 34.4% (n = 21) in the control group. The proportion of wound healing experienced at week 2 was 89.2% (n = 58) in the treatment group compared with 27.9% (n = 17) in the control group. There was a significantly greater reduction in wound surface area relative to baseline in the treatment group (2.9 cm² ) compared with the control group (0.6 cm² ) (χ² = 21.792 P < .0001) at week 1. Survival analysis data supported that skin tears healed 50% faster in the treatment group (11 days) compared with the control group (22 days) (χ² = 59.677 P < .0001). The expected healing trajectory of acute wounds, including skin tears, if proper wound bed preparation is realised and infection is controlled, is 7 to 21 days. Results of this study suggest the use of silicone dressings support wound healing and aid in wound closure within the expected healing trajectory, with faster complete wound closure and mean healing times compared with non-silicone dressing for the treatment of STs.
