M.A.I.D : A Prognostic Score Estimating Probability of Healing in Chronic Lower Extremity Wounds

To evaluate a wound-based prognostic score for chronic lower extremity wounds suitable for daily routine use capable of predicting long-term healing. The main obstacle in the treatment of chronic wounds is to estimate long-term clinical outcome. For diabetic foot ulcers, several ulcer, and nonulcer-related risk factors associated with impaired healing have been described in the past. A new chronic lower extremity ulcer score (M.A.I.D.) was created out of 4 clinically defined parameters, namely palpable pedal pulses (I), wound area (A), ulcer duration (D), and presence of multiple ulcerations (M). Palpable pedal pulses were categorized by the absence (scored as 1) or presence (scored as 0) of pedal pulses, while wounds >4 cm were scored as 1 and wounds < or = 4 cm as 0. Ulcers lasting more than 130 days were categorized as 1 and wounds with a duration of
