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.

ABSTRACT

INTRODUCTION: Integration has been recognized as an important aspect of medical education. After transitioning from a discipline-specific to a systems-based preclinical curriculum, we examined faculty perceptions of the integrated approach and also whether it would lead to better anatomy knowledge retention. METHODS: To understand faculty perspectives, we reviewed curricular materials, interviewed block directors, and observed educational sessions. We analyzed knowledge retention through a 27-question anatomy test, comparing scores from the last class of the discipline-based curriculum and the first two classes of the integrated curriculum. RESULTS: Planning integrated content involves purposeful ordering, is challenging for faculty, and requires additional resources. Evaluation of the integrated approach for anatomy content demonstrated a significant increase in knowledge retention (p = .012; 56.28% vs. 63.98% for old vs. new curriculum). CONCLUSIONS: This study helps the understanding of what is required for curricular integration. Our anatomy evaluation results corroborated the view that contextually embedded information is easier to learn and retain.
