Poster Session: From Paper to Precision: Improved MADRS Scoring Accuracy with eCOA Implementation
Abstract:
This study investigates whether using electronic clinical outcome assessments (eCOA) can reduce scoring errors in the Montgomery–Åsberg Depression Rating Scale (MADRS) compared to traditional paper-based methods. In clinical trials for depressive disorders, data variability and rater errors often compromise the reliability of results, with paper-based assessments being particularly prone to mistakes due to manual calculations and transcription. The eCOA platform, by contrast, offers automated scoring, real-time data validation, and built-in consistency checks, which help standardize the assessment process and minimize errors. The researchers analyzed MADRS assessments from two large clinical trials – one using paper and the other eCOA – and found that scoring discrepancies were dramatically lower with eCOA. The findings highlight the clinical and operational benefits of eCOA, such as improved data quality, reduced administrative burden, and greater reliability in psychiatric clinical trials, despite potential methodological differences between the studies.
