The aims of this study were to compare the reproducibility, completion times and ability to predict 30-day amputation of the WIfI, University of Texas Wound Classification System (UTWCS), Site, Ischemia, Neuropathy, Bacterial Infection and Depth (SINBAD) and Wagner classifications systems using photographs of diabetes-related foot ulcers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Three trained observers independently scored the diabetes-related foot ulcers of 45 participants on two separate occasions using photographs. The inter- and intra-observer reproducibility were calculated using Krippendorff\u2019s \u03b1. The completion times were compared with Kruskal-Wallis and Dunn\u2019s post-hoc tests.

There was moderate, substantial, or excellent agreement within the three observers (\u03b1&gt;0.599 in all instances except one) and fair or moderate agreement between observers (\u03b1 of UTWCS=0.306, \u03b1 of SINBAD=0.516, \u03b1 of Wagner=0.374) for the other three classification systems. The WIfI score took significantly longer ( P&lt;.001) to complete compared to the other three scores (medians and inter quartile ranges of the WIfI, UTWCS, SINBAD, and Wagner being 1.00 [0.88-1.00], 0.75 [0.50-0.75], 0.50 [0.50-0.50], and 0.25 [0.25-0.50] minutes).
