In patients with venous and lymphovenous disease, skin changes to the lower limb(s) occur gradually, and become more serious over time if left untreated. The CHRonic Oedema Signs and Symptoms (CHROSS) Checker is a tool kit consisting of an assessment chart and key cards that have been developed to help clinicians easily identify the skin changes that occur as a result of underlying venous and lymphovenous disease, when carrying out holistic patient assessment. It also provides clear guidance on which compression products can be used to manage the disease type and severity of skin change. For clinicians unfamiliar with some or all of the signs and symptoms listed on the CHROSS Checker chart, the key cards contain further information in the form of a photograph, definition and cause of each sign and symptom listed. This article will describe the theory behind the development of the CHROSS Checker tools and explain how to use them in clinical practice.
