Neurostatus e-Scoring improves consistency of Expanded Disability Status Scale assessments: A proof of concept study:
2017
Background:To improve the consistency of standardized Expanded Disability Status Scale (EDSS) assessments, an electronic data capture tool and analysis tool was developed, Neurostatus e-Scoring (NESC). This tool allows real-time feedback by comparing entries with established scoring rules.Objective:To test whether using NESC reduces inconsistencies as compared to the paper-and-pencil version of the Expanded Disability Status Scale (pEDSS).Methods:In all, 100 multiple sclerosis (MS) patients were assessed in random order on the same day by pairs of neurologists, one using pEDSS and one NESC. We compared inter-rater reliability and frequency of inconsistencies in Neurostatus subscores, functional system (FS) scores, ambulation and EDSS steps.Results:Inconsistencies of any type were more likely to occur when using pEDSS (mean odds ratio (95% confidence interval (CI)) = 2.93 (1.62; 5.29)). This was also the case for FS score inconsistencies (2.54 (1.40; 4.61)) and more likely for patients in the lower EDSS ra...
