Randomized trial of cohesive short-stretch versus four-layer bandaging in the management of venous ulceration.
A multicenter prospective randomized clinical trial was undertaken to compare a generic four-layer bandage system with a cohesive short-stretch system (Actico, Activa Healthcare) in the management of venous leg ulceration. Both systems are designed to produce sufficient pressure to counteract venous hypertension. Patients in leg ulcer services with leg ulceration were screened for inclusion in this trial. Patients with arterial disease (ankle brachial pressure index < 0.8) and causes of ulceration other than venous disease were excluded. For patients with bilateral ulceration, the limb with the larger area of ulceration was studied. Patients were randomized to receive either type of compression bandage and simultaneously randomized to one of two foam dressings that were changed weekly unless more frequent changes were clinically required. In all, 156 patients met entry criteria and were randomized from the 12 clinical centers with median (range) ulcer size of 4.33 (0.33-123.10) cm(2). Analysis revealed that after 24 weeks a total of 111 (71%) of patients had complete ulcer closure, 32 (21%) had withdrawn from the trial, 12 (8%) remained with open ulceration, and one patient had died. Of the 74 patients randomized to the four-layer bandage, 51(69%) had ulcer closure on treatment compared with 60/82 (73%) on the cohesive short-stretch system. Intention-to-treat analysis produced a hazard ratio for healing of 1.08 (95 percent CI 0.63-1.85, p= 0.79). Withdrawal rates were similar between groups (15, 20% four-layer bandage; 17, 21% cohesive short-stretch system). Ulcer closure rates for patients treated with the cohesive short-stretch system were similar to those for patients managed by the four-layer bandage system in this trial.
