Comparative Effectiveness of a Bilayered Living Cellular Construct and an Acellular Fetal Bovine Collagen Dressing in the Treatment of Venous Leg Ulcers

Aim: To compare the effectiveness of bilayered living cellular construct (BLCC) and an acellular fetal bovine collagen dressing (FBCD) for the treatment of venous leg ulcers. Methods: Data from WoundExpert® (Net Health, PA, USA) was used to analyze 1021 refractory venous leg ulcers treated at 177 facilities. Results: Kaplan-Meier analyses showed that BLCC (893 wounds) was superior to FBCD (128 wounds), p = 0.01 for: wound closure by weeks 12 (31 vs 25%), 24 (55 vs 43%) and 36 (68 vs 53%); reduction in time to wound closure of 37%, (19 vs 30 weeks); and improvement in the probability of healing by 45%. Conclusion: BLC versus FBCD showed significant differences in both time to and frequency of healing suggesting that BLCC may provide significant cost savings compared with FBCD.
