Aquacel Ag Advantage/Ag+ Extra and Cutimed Sorbact in the management of hard-to-heal wounds: a cohort study.

Abstract

To compare Aquacel Ag Advantage/Ag+ Extra (Aquacel Ag+) (Convatec, UK) and Cutimed Sorbact (Sorbact) (Essity, US) dressings indicated for the treatment of patients with venous leg ulcers (VLUs), diabetes foot ulcers (DFUs) and pressure injuries (PIs) for clinical performance and outcomes using real-world evidence in Germany and the US. This study was a chart audit review of patients who used either Aquacel Ag+ or Sorbact dressings in the 24 months prior to October 2022. Healthcare providers with access to electronic medical records and charts were asked to capture data via patient record forms. The quantitative data were analysed. Findings in Germany were comparable between Aquacel Ag+ and Sorbact with regards to wound description, management and treatment outcomes, including percent area reduction and wound closure. A difference was that a greater proportion of Sorbact patients required surgery (0% versus 11%; p=0.039). In the US, a greater proportion of wounds were worsening before dressing in the Aquacel Ag+ cohort (49% versus 34%; p=0.010). A multinomial logistic regression yielded the result that patients who received Aquacel Ag+ were 3.53 times more likely to have the wound completely healed (p=0.033). Both Aquacel Ag+ and Sorbact dressings are widely used in Germany and the US for patients with VLUs, DFUs and PIs. Our study found two important differences: patients who used Aquacel Ag+ were less likely to need further surgery in Germany; and in the US, there were significantly higher odds that wounds would completely heal with Aquacel Ag+ dressings compared to Sorbact.
