The disease activity of Behçet`s disease is inadequately defined, and there is no consensus on how it should be measured. The aim of this study was to verify the usefulness of a simplified electronic medical record (EMR)-based activity index (EMRAI) for Behçet`s disease.
A total of 73 Korean patients with Behçet`s disease participated in this study. Two dermatologists interviewed each participant independently using two activity scoring systems: the EMRAI and the Behçet`s Disease Current Activity Form (BDCAF). Overall agreement between raters, correlation between activity scoring indices, and total interview run-time were evaluated.
The EMRAI significantly correlated with the BDCAF (Spearman`s correlation coefficient, r=0.835), physician-assessed overall activity score (r=0.782), erythrocyte sedimentation rate (r=0.520) and C-reactive protein level (r=0.422). The weighted kappa score for inter-rater agreement of EMRAI showed very good reliability compared with that of BDCAF (0.894 and 0.693, respectively). The mean total run-time for the EMRAI was shorter than that required to administer the BDCAF (95 s and 115 s, respectively).
The EMRAI, an EMR-based simplified activity index of Behçet`s disease, facilitates rapid and simple gathering of disease activity data and clinical information.
