Filling in the Gaps: Using Convexity to Meet Ostomy Patient Needs

Purpose:

The needs for convexity are based on patient assessment and knowledge of product features.  This poster will explore the variety of options for achieving convexity and provide clinical applications that demonstrate best practice.  Although different products are available globally, the goal is to examine commonalities of clinical approaches. 

Statement of Problem:

Convexity can enhance skin protection, wear time and comfort.  Used incorrectly can result in complications including skin damage and leakage.  

Assessments of the abdomen and peristomal field occur immediately postoperatively and over the long-term.  The goal of convexity is to fill defects in the skin and provide a secure, predictable seal.  Convexity solutions have evolved over many years.  With the introduction of different convex forms, the decision making process is now less straight forward.  Both the novice and advanced practitioners may benefit from terminology clarification and guidelines related to convexity product use.  

Summary:

Traditional convex products, where a firm dish is integrated into an ostomy skin barrier, provide varying degrees of peristomal pressure.  These have been examined with relative frequency and are generally well understood by clinicians directly involved in stoma care.  

However, the evolution of convex options coupled with differing terminology used by manufacturers today can be confusing.  This may include firm and soft convex options which are either integrated or custom built with accessories.  Each type of convexity should be part of the ostomy nurses armamentarium to manage both basic and challenging abdomens and stomas. Appropriate utilization of convexity is based upon ongoing stomal, abdominal plane and peristomal skin assessments coupled with best practices.  Clarifying product descriptions and indications for use will provide clinical guidance and enhance patient outcomes.
