Three Ways That eCOA Improves Data Quality

In recent years, many in the research industry have transitioned from manual, paper-based clinical outcome assessment (COA) strategies to the digital alternative (eCOA), discovering the benefits and advantages – both for patients and study teams – of eCOA over paper. A key advantage of eCOA is the facilitation of more accurate and reliable data collection, leading to better quality study data overall. Despite this, some researchers continue to rely on labor-intensive manual methods for collecting COA data.  

The following is a quick guide to the key ways that eCOA works to help all study stakeholders (patients, caregivers, study teams, etc.) produce better data.
