Observational Study of Venous Leg Ulcer Treated With a Native Collagen-Alginate Dressing and the Impact on Wound-Related Quality of Life
Summary: In an observational single-center study of 60 patients with non-healing venous leg ulcers (VLUs; mean duration 1.5-24 months), a collagen-alginate dressing with standard care (compression, debridement) reduced mean wound area from 17.8 to 11.4 cm² (32% relative reduction, P<0.0001) over 4 weeks, with 8% complete closure. Pain dropped (VAS 3.9 to 1.7, P<0.0001), analgesic use halved, and QoL improved (total score P<0.0001), correlating with wellbeing gains. Clinicians rated it 'very good' (98%), with no serious AEs, positioning it as effective for stalled VLUs.
Key Highlights:
- Wound area: 32.2% mean reduction; 4/50 complete closures (8%).
- Pain: VAS decreased 2.2 points; pain-free patients rose from 15% to 49%; analgesics from 61% to 33%.
- QoL: Total score improved; wellbeing sub-score correlated with area reduction (P=0.0002).
- Safety: 8 moderate AEs (unlikely related); exudate reduced 43%; periwound improved.
