A comprehensive literature review was conducted to examine research, current best evidence, and best practice recommendations associated with the use of convex skin barriers for patients living with an ostomy. The review revealed a fragmented array of citations related to convexity and a paucity of evidence regarding convexity product descriptions and application. Most convexity choices appear to be based on the clinician experience over time using trial and error to determine clinical application. Current descriptors used for convexity products are creating confusion, and a standardized approach to product nomenclature does not exist. The development of assistive clinical practice guidelines, in conjunction with further research, is recommended.
