Knighton et al evaluated chronic nonhealing wounds using the Total Wound Score, which consists of 3 parts. The final score is a sum of the 3 subscores.The authors are from the University of Minnesota in Minneapolis.
Patient selection: chronic nonhealing wound from mixed etiologies (decubitus, diabetic, arterial, venous stasis, other)
Parameters:
(1) general wound appearance (range 0 to 32)
(2) anatomic considerations (range 0 to 27)
(3) wound measurements (range 0 to 38)
total score =
= SUM(points for all 3 subscores)
Interpretation:
• minimum score: 0
• maximum subscore: 97
• The higher the score the more severe the wound.
• The score decreases with effective treatment with healing.
delta score =
= (previous score) - (current score)
percent change =
= (delta score) / (previous score)
