There is considerable emphasis at a strategic level across the whole of the UK to reduce the number of patients who develop a PU, with particular focus on the more serious Category III and IV ulcers. However, it has been demonstrated that practitioners have difficulty differentiating between a Category II and a Category III ulcer, which has political, legal and financial implications. Accurate classification of a wound may be assisted by the use of a monofilament debridement pad, allowing practitioners to better visualise the wound bed and differenitate with greater accuracy between a Category II and III ulcer.
