Convexity in stoma care: developing a new ASCN UK guideline on the appropriate use of convex products.

ABSTRACT

One of the biggest challenges for specialist stoma care nurses (SCNs) caring for anyone living with a stoma is that of being confronted with a problematic stoma. This can be described as an ostomy that continues to cause leakage issues for the patient which, if persistent can quickly impact negatively on their quality of life. A convex stoma appliance, also termed convexity, is a possible solution to a problematic stoma. However, the use of a convex appliance should be considered only after a thorough assessment has been undertaken by a specialist SCN. Professionally, stoma care nursing has advanced greatly in recent years and there has been a realisation that there is a need for clinical guidelines to direct practice and offer a process for the novice SCN to follow. This realisation has been the catalyst behind the development of the new guideline for the assessment and use of convexity by the Association of Stoma Care Nurses UK, which was published this year (https//ascnuk.com/). This article explores the concept of convexity and how the guideline can assist the practice of specialist SCNs, as well as that of ward and community-based nurses who wish to gain more information on using convexity within the specialist sphere of stoma care.
