Wound assessment should be comprehensive, systematic and evidence-based (World Union of Wound Healing Societies [WUWHS], 2016a). The Triangle of Wound Assessment offers clinicians a framework to assess the patient and their wound, taking into consideration the wound bed, wound edge and periwound skin (Dowsett et al, 2015). The framework can be adapted to incorporate new developments and new challenges in wound care such as the ‘gap challenge’ and biofilm prevention and management.
