Abstract
Background: Comparing keloid treatment modalities and assessing response to treatments may be predicted by a better classification system. Objectives: To develop and validate the Detroit Keloid Scale (DKS), a standardized method of keloid assessment.
Methods: Forty-seven physicians were polled to develop the DKS. The scale was validated in 52 patients against the Vancouver Scar Scale (VSS), Patient and Observer Scar Assessment Scale (POSAS), and Dermatology Life Quality Index (DLQI).
Results: The inter-rater reliability was "substantial" for observer DKS and only "moderate" for VSS and observer POSAS (intraclass correlation coefficient were 0.80, 0.60, and 0.47, respectively). Pearson's correlation indicated "moderate" association between observer DKS with observer POSAS (ρ = 0.56, p < 0.001) and "substantial" relationship between observer DKS and VSS (ρ = 0.63, p < 0.001). Pearson's correlation indicated "moderate" association between patient portion of DKS and patient portion of POSAS and patient portion of the DKS and DLQI (0.61 and 0.60, respectively, p < 0.05). DKS total score consistently showed significant "substantial" relationship with POSAS total score (ρ = 0.65, p < 0.001).
Conclusions: The DKS offers a validated keloid-specific outcome measure for comparing keloid treatments.
