Wound management research improves patient care and clinical
outcomes by standardising assessment, planning and implementation
of treatment. In the field of wound care, high-level evidence is
possible, but it can be difficult to conduct due to the wide-ranging
nature of wounds and patients.
Additionally, there is an ever-growing variety of products and devices available to practitioners to improve healing rates and patient outcomes. In many cases, these products have enabled practitioners to heal more complex wounds and manage more
challenging and difficult cases. However, practitioners must be able to critically appraise evidence to make appropriate and effective evidence-based changes to practice.

A Prospective Study on the Efficacy of Sequential Treatment of Technology Lipido‐Colloid Impregnated with Silver and Technology Lipido‐Colloid Nano‐Oligosaccharide Factor in the Management of Venous Leg Ulcers
Background and Aims: Venous leg ulcers (VLUs) are associated with significant morbidity and poor quality of life (QOL). Compression therapy and wound dressing are the mainstay treatment options. Technology Lipido‐Colloid Impregnated with Silver (TLC‐Ag) reduces bacterial load and Technology Lipido‐Colloid Nano‐Oligosaccharide Factor (TLC‐NOSF) reduces elevated matrix metalloproteinases and improve wound healing. However, evidence is scarce on the role of sequential therapy. This study aims to evaluate if sequential treatment with TLC‐Ag and TLC‐ NOSF improves VLU wound healing and QOL.
Methods: This is a prospective cohort study from May 2020 to October 2021 on patients with VLUs who received sequential therapy, consisting of 2 weeks of TLC‐Ag followed by two‐layer compression bandage (2LB) with TLC‐NOSF until complete wound healing. Participants were followed‐up with weekly dressing changes. Our primary outcomes were wound area reduction (WAR) and Pressure Ulcer Scale of Healing (PUSH) score. Our secondary outcomes were QOL measures.
Results: There were 28 patients with 57.1% males (n = 16) with a mean age of 65.3 years. Mean duration of VLU was 13.9 ± 11.7 weeks before the initiation ofsequential therapy. Mean baseline wound area was 8.44 cm2
. Median time to wound healing was 10 weeks. 57.1% of patients achieved complete wound closure at3 months. There was significant WAR after 1 month (mean area 8.44–5.81 cm2 , 31.2% decrease) and after 3 months (mean area 8.44–2.53 cm2 , 70.0% decrease). Mean monthly WAR was 28.9%. PUSH score also decreased at 1 month (16.5% decrease, p < 0.001) and 3 months (63.3% decrease, p < .001) marks following the sequential therapy. EuroQol Visual Analog Scale (EQ‐VAS) improved following sequential therapy
(baseline: 69.0 ± 15.0, week 13: 80.2 ± 13.2, p < 0.001).
Conclusion: Sequential therapy with TLC‐Ag followed by TLC‐NOSF and 2LB is feasible, with good wound healing and improvement in QOL of patients with VLUs.
