Usability Is Data Quality

Central Nervous System (CNS) clinical trials rely on complex, high-stakes assessments to measure cognitive function, disease progression, and treatment outcomes. The quality of these evaluations hinges on both the expertise of raters and the capabilities of the technologies supporting them. Electronic clinical outcome assessment (eCOA) systems play a vital role in standardizing data capture and enhancing the rater experience, which directly impacts data integrity.

To support accurate and consistent assessments, science-informed eCOA technologies must offer key features tailored to the needs of CNS trials. Additionally, versatile annotation tools—such as typing, stylus, and image capture—allow raters to document observations in their preferred format, improving completeness and clarity. By integrating these capabilities, eCOA platforms not only streamline rater workflows but also reduce variability in assessment execution. This usability-focused design leads to higher-quality data, improved trial efficiency, and a reduced burden on raters.
