Martins et al reported the Ostomy Skin Tool (OST) to evaluate peristomal skin. A significant component of the OST score was the DET score (discoloration, erosion, tissue overgrowth). The authors are from institutions in Canada, the United States, Denmark and the Netherlands.
Patient selection: stoma present
Parameters:
(1) discoloration
(2) erosions
(3) tissue overgrowth
(4) area of discoloration (based on percent of area under the adhesive barrier)
(5) area of erosions(based on percent of area under the adhesive barrier)
(6) area of tissue overgrowth(based on percent of area under the adhesive barrier)

subscore for skin changes =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 15
• The higher the score the more severe the peristomal skin changes.
