TABLE 2. Consensus Statements.

Product characteristics Some convex products are firm Some convex products are soft A belt can be used to enhance the effect of convexity The effect of convexity can be enhanced if placed close to the base of the stoma

Patient assessment To best assess the need for convexity, the pouching system must be removed The best position for assessment for convexity is the sitting position Assessment for convexity includes type of output (such as formed, semi-formed, and loose or liquid) Assessment for convexity includes the location of the stoma opening, stoma height, whether the stoma telescopes, and location of distal lumen in the loop or double-barrel stoma Assessment for convexity includes abdominal tone, contour of peristomal region, and the presence of peristomal skin disorders An ostomy patient using convexity must be reassessed based on individual needs An ostomy patient using convexity must be reassessed based on clinician judgment Assessment of harmful effects of convexity (such as ulceration, pain) is needed with each pouching system change

Indications Convexity can be used with colostomy, ileostomy, and urostomy Liquid output can be an indicator for convexity to prevent or manage leakage Stoma opening at the level of the skin can be an indicator for convexity A protruding stoma can require convexity With a firm peristomal region, soft convexity can be a better option than firm convexity With a soft peristomal region, firm convexity can be a better option than soft convexity People with peristomal skin disorders can require convexity In the immediate postoperative period, convexity can be considered The stoma care nurse is best prepared to advise patients and health care providers on the appropriate use of convexity Loop stomas with the distal opening at skin level can be an indicator for convexity Stoma opening that is off-center can be an indicator for convexity A stoma opening below the level of the skin can be an indicator for convexity Convexity can be used to manage enterocutaneous fistulae

Outcomes Use of convexity can extend wear time
