Seventy patients with 90 venous ulcers were randomly assigned to hydrocolloid or conventional dressing and compression therapy at four study centers. The ulcers had been present for a mean of 47.8 in the control and 46.2 weeks in the treatment group and 42% of all patients had recurrent ulcers. Ulcers treated with hydrocolloid dressings reduced 71% and control treated wounds reduced 43% in area after 7.2 weeks of treatment. Thirty-four percent of all ulcers healed. Mean time to healing was 7 weeks for the hydrocolloid dressing group and 8 weeks for the control group. Most ulcers were less painful at final evaluation, but reduction in pain was more pronounced in hydrocolloid-dressed ulcers (p = 0.03). At baseline as well as during follow-up, significant differences between study centers were observed. Ulcers in patients in the United Kingdom were larger and less likely to heal (p = 0.001). Size of the ulcer at baseline was associated with treatment response and time to healing (p = 0.002). Percent reduction in ulcer area after 2 weeks was also correlated with treatment outcome (p = 0.004) and time to healing (p = 0.002). When all treatment outcome predictors were analyzed together, only percent reduction in area after 2 weeks remained statistically significant (p = 0.002), with percent reduction during the first 2 weeks of treatment > 30% predicting healing.
