Economic benefit of a novel dual-mode ambulatory compression device for treatment of chronic venous leg ulcers in a randomized clinical trial.

BACKGROUND: Limb compression is a key component of protocols used to heal venous leg ulcers (VLUs). A novel ambulatory pneumatic compression device was tested in comparison with multilayered bandage (MLB) compression systems for the treatment of VLUs in a prospective randomized clinical trial. METHODS: Patients with VLUs measuring 1.5 to 50 cm2 with duration of 1 to 24 months were randomized to treatment with a pneumatic compression device, the ACTitouch adaptive compression therapy (ACT) system (Tactile Medical, Minneapolis, Minn), or MLB. The ACT group patients were seen in the clinic at weeks 1, 2, 4, 6, 9, 12, and 16 or until wounds healed; the MLB group was seen weekly for bandage and dressing changes for 16 weeks or until wounds healed. All other aspects of VLU care were standardized between the two groups. The primary study objective was to compare the VLU percentage area reduction at 16 weeks in the ACT group compared with the MLB group. RESULTS: There were 56 patients randomized to treatment with ACT (n = 26) or MLB (n = 30). In the ACT group, five patients exited because of skin or wound problems related to the ACT device and five withdrew because of the inconvenience of using the device. Therefore, the trial was halted before full randomization so improvements to the ACT device could be made. Data collected on 42 patients who were able to tolerate treatment for the 16-week study period (per protocol group) showed that both groups experienced similar rates of wound healing. In the per protocol population, the percentage area size reduction was greater for the ACT group compared with the MLB group (83.8% vs 70.5%, respectively), whereas no significant differences were noted in the percentage of wounds that healed by 16 weeks (60.0% vs 63.0%, respectively). CONCLUSIONS: In this truncated clinical trial, a novel dual-mode ambulatory compression device, when tolerated, achieved wound healing results similar to those with MLB for chronic VLUs. The device requires modifications to improve the patient's comfort and ease of use. However, this mode of therapy appears to have promise for improving the cost-effectiveness of treatment for chronic VLUs.

Diabetic foot ulcers--effects on QOL, costs, and mortality and the role of standard wound care and advanced-care therapies.

Diabetic foot ulcers (DFUs) are a common and serious complication of diabetes mellitus. A review of the literature confirms that the presence of an unhealed DFU negatively affects several domains of patient quality of life (daily and social activities) and increases the risk of infection, amputation, and death. Patients with diabetes mellitus and DFUs also have higher healthcare utilization rates than patients without DFUs and reported healing rates vary from 24% to 82% after 12 weeks of care. Guidelines for the expeditious healing of DFUs are available and include debridement, infection control, offloading, and the use of dressings that maintain a moist wound bed. Wound measurements to determine progress toward healing must be obtained because percent reduction in wound area during the first 4 weeks of care is a predictor of treatment outcome. If a wound fails to respond to standard care, the use of advanced treatment approaches such as cytokines, negative pressure therapy, and living skin equivalents may be beneficial. Clinical studies to further elucidate the effects of topical, systemic, and supportive regimens of care on outcomes and costs are needed.
