Effect of Chinese herbal compound dressings in treating patients with diabetic foot ulcers: A meta-analysis.

Abstract

This meta-analysis aims to systematically investigate the clinical efficacy of Chinese herbal compound dressings in treating patients with diabetic foot ulcers (DFUs). A comprehensive computerised search was conducted in databases including PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases, from database inception to November 2023, to identify randomised controlled trials (RCTs) concerning the use of Chinese herbal compound dressings in patients with DFU. Two researchers independently screened the literature, extracted data, and assessed the quality based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. Overall, 18 RCTs involving 1405 DFU patients were included. The analysis indicated that compared to the control group, the group treated with Chinese herbal compound dressings had significantly shorter ulcer healing time (standardised mean difference [SMD] = -2.49, 95% confidence interval [CI]: -3.53 to -1.46, p < 0.001), reduced ulcer surface area (SMD = -3.38, 95% CI: -4.67 to -2.09, p < 0.001), and higher healing rates (odds ratio [OR] = 2.24, 95% CI: 1.72-2.92, p < 0.001) as well as overall effectiveness rates (OR = 4.56, 95% CI: 3.10-6.71, p < 0.001). This study demonstrates that the external application of Chinese herbal compound dressings in patients with DFU can significantly shorten the ulcer healing time and improve wound healing rates.
