Medidata eCOA

Accelerating Your Path
to Decentralized Clinical Trials

Medidata eCOA (Clinical Outcome Assessment) is revolutionizing the way sponsors, CROs, and sites collect electronic data from patients, physicians, and caregivers. Available as an iOS or Android app or web-based solution, Medidata eCOA provides a flexible, intuitive model for capturing patient data that is designed to make it easier for patients to engage in clinical trials.

Built as part of the unified Medidata Clinical Cloud® platform, Medidata eCOA improves your study experience with flexible deployment options, a groundbreaking global instrument library, and dedicated services and support.

Image Capture Directly Into eCOA

Combining the power of Medidata eCOA with Rave Imaging, eCOA Image Capture enables patients and caregivers to take and share pictures from their mobile devices and upload them directly into the Medidata eCOA app, eliminating the need for extra site visits or multiple technology solutions. Images become available for immediate review, delivering greater insights for both sites and sponsors, while enhancing the patient experience. This patient-centric feature also enhances the use of eCOA in hybrid and decentralized clinical trials.

The Medidata eCOA Difference

Faster Study Start Times

Implementing eCOA accelerates study start time through a library of pre-built, pre-approved instruments. Providing a single point of data entry, there are fewer queries and cleaner data. As part of a unified platform, there’s no end-of-study mapping or integration required.

Unified Platform Approach

The Medidata Clinical Cloud provides a clear view of all your cross-application data in one place. Integrate with your existing data systems, eliminating manual data entry and reconciliation, while maintaining full control and oversight.

Flexible and Easy to Use

Medidata eCOA’s agility allows patients to engage where, and when, they choose. Information syncs immediately into the clinical dataset, allowing real time visibility. Enhancing the patient journey is a dedicated Patient Cloud Helpdesk, easing patient burden and making decentralized trials a reality.
