WoundExpress to manage lower leg wounds

The technology described in this briefing is WoundExpress. WoundExpress is an advanced wound therapy device, which uses intermittent pneumatic compression to promote lower leg wound healing for people at home.

The innovative aspects are that, unlike with standard treatment, WoundExpress is placed on the thigh of the ulcerated limb, rather than the wound site. The company claims this improves circulation to the wound site without having to apply direct pressure to the wound bed.

The intended place in therapy would be alongside current wound management for people with hard to heal lower leg wounds.

The main points from the evidence summarised in this briefing are from 6 studies including 2 observational studies and 4 case series. They included a total of 121 adults, who were mostly at home. They suggest that WoundExpress could improve the management of hard to heal lower leg wounds.

Key uncertainties around the evidence are that patient numbers are small and internal validity is weak, with no comparators in the studies, making it difficult to confirm the cause of the outcomes.

Safety issues identified are that the device should not be used with several conditions, including severe peripheral artery disease (ankle brachial pressure index of 0.6 or less), suspected deep vein thrombosis, and significant limb oedema.

The cost of WoundExpress is £114 per week, based on a recommended 8‑week rental period. This includes the WoundExpress pump and a single garment. Quantity and duration discounts may apply. WoundExpress should be used alongside standard care.
