Erratum: Measurement of Convexity Characteristics: A Transdisciplinary Consensus Conference

In the January/February 2025 issue of Journal of Wound, Ostomy, and Continence Nursing, in the article by Beitz et al., “Measurement of Convexity Characteristics: A Transdisciplinary Consensus Conference,” the legends for Figures 3 and 4 were incorrect. The correct legends are listed below. Figure 3. Tension location is the diameter at which the dome/protrusion begins to curve toward the base measured in millimeters. This measurement is considered relative to stoma size. Figures 4. Flexibility may be measured using a 3-point bend or buckling test. A 3-point bend test is completed by placing the skin barrier curved side down, on a machine with 2 support pins. A third pin is pressed down on the center of the barrier, forcing it to bend to a specified (and consistent) level. A buckling test is completed by mounting a convex skin barrier vertically between 2 steel plates. The upper steel plate pushes down on the barrier, flexibility is quantified as the magnitude of force (in N-mm) needed to make the barrier bend (“buckle”) to a specified (and consistent) level. Similar to the 3-point bend, force required to bend is measured, with higher figures representing more rigid/lower figures showing more flexible products. Flexibility is defined as the force needed to achieve this bend (measured in N-mm); a skin barrier that resists bending (more rigid) requires higher force while a barrier that yields easily (more flexible) requires lower force.
