Trial of two bandaging systems for chronic venous leg ulcers

A four-layer bandaging system developed at Charing Cross Hospital has been found to be effective in healing chronic venous ulcers but is not available on the Drug Tariff. An alternative system was devised from bandages available on the Drug Tariff and a community-based randomised controlled trial was undertaken to compare the two systems. Twenty-nine patients with a total of 35 ulcerated legs were recruited. Equal numbers of ulcerated legs healed using the two compression systems. Nineteen ulcerated legs did not heal, of which six were withdrawn from the trial-two in the trial system and four in the Charing Cross system. Of the 13 remaining ulcerated legs, for which treatment was completed, the mean reduction in ulcer area was 34% with the trial system and 39% with the Charing Cross system. The change in ulcer area was not statistically significant. However, a much larger trial is required in order to demonstrate definitively that the two bandaging systems are equivalent.
