Use of a TLC-Ag dressing on 2270 patients with wounds at risk or with signs of local infection: an observational study

Abstract

Objective: A description of wounds treated with a poly-absorbent silver dressing (with technology lipido-colloid with silver ions, TLC-Ag), and evaluation of the short-term clinical impact of the dressing on the wound healing process, under real-life conditions. Method: A large, prospective, multicentre, observational study of patients in 81 centres in Germany, presenting with an exuding wound at risk or with clinical signs of local infection for whom the evaluated TLC-Ag dressing (UrgoClean Ag, Laboratoires Urgo, France) has been prescribed. Main outcomes included: reduction in number of wound infections diagnosed and clinical signs of local infection, wound healing rate, clinical assessment of wound healing progression, relative wound area reduction (RWAR), local tolerability, handling and acceptance of the dressing. Results: A total of 2270 patients with acute and chronic wounds of various aetiologies were treated with the evaluated dressing for a mean duration of 22±13 days. All clinical signs of local infection and the diagnosed wound infections were substantially reduced at two weeks after the treatment initiation. All wound infection parameters continued to reduce until the last visit. In the meantime, clinical improvement in wound healing was reported in 98.9% of acute wounds, with a wound closure rate of 68.5%. In chronic wounds, a median RWAR of 57.4% was achieved, with an improvement in healing process documented by clinicians in 90.6% of cases, stabilisation in 6.1% and worsening in 3.2%. Similar results were reported, regardless of exudate level and proportion of sloughy and granulation tissues in the wound bed at baseline. The dressing was well tolerated and well accepted by both patients and health professionals. Conclusion: These results, documented in a large cohort of patients treated in current practice, support and complete the clinical evidence on the healing properties and safety profile of the TLC-Ag dressing in the management of wounds at risk or with clinical signs of local infection, regardless of wound and patient characteristics.
