The efficacy of sacral foam dressing in preventing sacral pressure injury: A systematic review and meta-analysis

Abstract

Purpose: We aim to evaluate the efficacy of sacral foam dressings in preventing sacral pressure injury. Methods: The PubMed, Embase and Web of Science databases were searched for relevant publications until October 2023. All studies evaluating the efficacy of sacral foam dressings in preventing sacral pressure injury were included. We calculated pooled risk ratio (RR) with 95% confidence intervals (CIs) for binary outcomes. The Cochrane's Risk of Bias Tool were used to evaluate the quality of studies. Results: A total of 9 randomized controlled studies with 3972 patients were included in this analysis. Sacral pressure injury rate was significantly lower in the sacral foam dressing group compared with the standard care group (RR: 0.37, 95% CI: 0.17–0.82). Furthermore, the rate of ≥stage II sacral pressure injury was also significantly reduced (RR: 0.56, 95% CI: 0.37–0.83), along with a lower blanching erythema rate (RR: 0.64, 95% CI: 0.42–0.97). No obvious publication bias was observed in the funnel plot (Egger's p values = 0.91). Conclusions: Sacral foam dressing significantly reduced the incidence of sacral pressure injuries, including those of stage II or higher, and blanching erythema when compared to standard care without sacral foam dressing. However, the results should be interpreted with cautious because of the observed heterogeneity and the diverse patient population. Further larger, well-designed randomized control studies are needed.
