Objective: To determine if a limited regimen of sequential gradient intermittent pneumatic compression ('HomeRx': HRx) is as effective in promoting the healing of chronic venous stasis ulcers as is the Unna's boot (UB), considered the 'gold standard' in compression therapy. Design: Fifty-three patients, aged 31-85 years, with ulcers ranging up to 31.8 cm2 (mean 9.9, SE 1.1) were prospectively. randomized to treatments with UB or HRx and followed weekly for 180 days or until healing was complete, whichever came first. The HRx group wore graduated compression stockings, which were removed only while intermittent pneumatic compression was applied bilaterally at home for 1 h each morning and 2 h each evening. The UB was re-applied at least weekly. The two groups were equivalent in their use of hydrocolloid dressings and periods of leg elevation. Setting: Therapy performed at home, with weekly visits to an outpatient clinic. Main outcome measures: Complete ulcer healing and the rate of healing, based on area and perimeter changes; amounts of wound exudate and pain. Results: Complete healing was achieved in 20 of 28 patients (71%) in the HRx group, compared with 15 of 25 (60%) treated with UB. Three patients had an adverse reaction to UB, one had cellulitis and five were non-compliant. Correcting for these withdrawn patients by life table analysis, healing rates were 76% and 64%, respectively. Healing rates did not correlate with haemodynamic measurements made prior to treatment. Conclusions: Using HRx for just a few hours daily to supplement graduated elastic compression heals venous ulcers at least as well as does the UB, without its disadvantages (e.g. the need for frequent re-application by qualified personnel, difficulty bathing), affording patients greater convenience during treatment.
