Coban 2 for venous leg ulcers

The technology described in this briefing is Coban 2 compression bandage for venous leg ulcers.

The innovative aspect is that it is thinner than 4‑layer bandages. This aims to improve mobility and convenience.

The intended place in therapy would be as an alternative to current compression bandages in selected people with venous leg ulcers.

The main points from the evidence summarised in this briefing are from 3 studies (2 in UK, 1 in Italy; comprising 2 randomised controlled trials [RCTs] and 1 observational study) including a total of 1,456 adults with venous leg ulcers. The evidence is limited in quantity and quality. One randomised study showed that Coban 2 slipped significantly less than 4‑layer bandages. The studies showed Coban 2 is as effective for wound healing as other compression bandages.

Key uncertainties around the evidence or technology are that there are no studies showing better wound healing than 4‑layer bandages.

The cost of Coban 2 is £8.24 per unit (excluding VAT). The resource impact would likely be similar to standard care (£4 to £15 depending on size of bandage).
