Abstract

BACKGROUND: This systematic review evaluated the efficacy of autologous skin cell suspensions (ASCS) on the re-epithelialization of partial thickness burn injuries and skin graft donor site wounds. METHODS: Four databases (EMBASE, Google Scholar, MEDLINE, Web of Science), grey literature and select journal hand-searching identified studies from 1975 - 2020. Randomized trials evaluating partial thickness burn management with non-cultured ASCS compared to any other intervention were included. Time to re-epithelialization (TTRE) was the primary outcome. Three independent researchers completed screening, data extraction and certainty of evidence assessment using Cochrane Risk of Bias Tool and Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Five trials (n = 347) reported on adults (2 trials) and children (1 trial) with burn wounds, and adults with donor site wounds (2 trials). The effect of ASCS compared to control on TTRE in adult burn wounds was not estimable. TTRE was shorter in pediatric burn wounds (SMD -1.75 [95% CI: -3.45 to -0.05]) and adult donor site wounds (SMD-5.71 [95% CI: -10.61 to-0.81]) treated with ASCS. The certainty of evidence was very low. CONCLUSION: Compared to standard care, ACSC may reduce pediatric partial thickness burn wound and adult split-thickness skin graft donor site TTRE.
