Key points
The relationship between the depth of the diabetes‐related foot ulcers, and the healing days, cost, and QOL was examined.
Depth 4 and 5 ulcers, namely beyond the tendons, exhibited significantly longer healing days and higher costs than Depth 2 and 3 ulcers. As for QOL, there were no significant differences in utility values between the depth categories.
Results on healing time and cost reiterate the importance of early consultation, especially before the depth becomes deeper than the tendon.
