Abstract

Real-world data are a highly valuable resource in determining the efficacy of novel products in challenging populations, especially in wound care. This study retrospectively analyzed the real-world performance of porcine placental extracellular matrix (PPECM; InnovaMatrix® AC, Convatec Triad Life Sciences, LLC, Memphis, TN, USA), a novel cellular, acellular, and matrix-like product for the management of hard-to-heal wounds. The US Wound Registry (USWR), which comprises aggregated and structured electronic health records from 502 wound practices, provided a deidentified dataset collected from October 10, 2022 to March 25, 2024, containing 76,278 patients (248,278 wounds). Screening for PPECM usage identified 60 wounds in 41 patients. The median age was 74 (IQR: 66-80) years; 20 (49%) had impaired ambulation, five (12%) autoimmune diseases, and five (12%) peripheral arterial diseases. The most common wounds included 18 (30%) chronic ulcers, 12 (20%) diabetic ulcers, seven (12%) pressure ulcers or injuries, seven (12%) dehisced surgical wounds, and six (10%) venous leg ulcers. Median surface area was 1.50 (IQR: 0.42-4.69) cm²; 31 (52%) of the wounds were limb/life-threatening (L/LT); nine (17%) were present >1 year; 52 (87%) had bioburden/infection. Only two (3%) of the wounds had no necrotic tissue at the initial application. Following PPECM management, 32 (53%) of the wounds closed (of which 14 (44%) were L/LT) and five (8%) had major improvement (three (60%) L/LT). No adverse events were reported. This is the first clinical study of PPECM and demonstrates the real-world safety and efficacy of PPECM in the management of hard-to-heal wounds in a complex population.

猪胎盘细胞外基质治疗难愈合伤口的实际应用和结果。
在确定新产品在具有挑战性的人群中的疗效方面,特别是在伤口护理方面,真实世界的数据是非常宝贵的资源。本研究回顾性分析了猪胎盘细胞外基质(PPECM;InnovaMatrix®AC, Convatec Triad Life Sciences, LLC, Memphis, TN, USA),一种新型细胞、非细胞和基质样产品,用于治疗难以愈合的伤口。美国伤口登记处(USWR)包括来自502个伤口实践的汇总和结构化电子健康记录,提供了从2022年10月10日至2024年3月25日收集的未识别数据集,其中包含76,278名患者(248,278处伤口)。筛选使用PPECM确定了41例患者的60处伤口。中位年龄为74岁(IQR: 66-80)岁;20例(49%)有行动障碍,5例(12%)有自身免疫性疾病,5例(12%)有外周动脉疾病。最常见的伤口包括18例(30%)慢性溃疡,12例(20%)糖尿病溃疡,7例(12%)压疮或损伤,7例(12%)手术伤口开裂,6例(10%)下肢静脉溃疡。中位表面积为1.50 (IQR: 0.42-4.69) cm²;肢体/危及生命(L/LT) 31例(52%);9例(17%)于2010年出现;52例(87%)存在生物负担/感染。只有两个(3%)的伤口在最初应用时没有坏死组织。经PPECM治疗后,32例(53%)伤口愈合(其中14例(44%)为L/LT), 5例(8%)伤口明显改善(3例(60%)为L/LT)。无不良事件报告。这是PPECM的首次临床研究,证明了PPECM在复杂人群中治疗难以愈合伤口的安全性和有效性。
