Beckert et al developed the MAID score for evaluating chronic wounds of the lower extremity. This can help to identify a wound that is likely to heal. The authors are from the University of Tubingen in Germany.
Patient selection: chronic wound of the lower extremity receiving optimum wound care.
Parameters:
(1) multiple ulcerations (M)
(2) area in square cm (A)
(3) palpable pedal impulses (I)
(4) duration in days

where:
• A single wound with an area of 4 square cm has a diameter of 2.25 cm (about an inch).
• The authors use area as a parameter but mention centimeters instead of square centimeters. If 4 cm is supposed to be the diameter then the area is 50 square cm. Also if multiple wounds were present areas would be easier to add than diameters.
total score =
= SUM(points for all 4 paraemters)
Interpretation:
• minimum score: 0
• maximum score: 4
• The higher the score the less likely that the wound will heal.
• An increase of 1 point decreases the chances of healing by 37%.
Limitations:
• The quality of care will impact healing.
