The collection of COA data using electronic data capture modes of administration is defined as an eCOA. eCOA modes of administration include but are not limited to:
- PC/Laptops (including web-based capture and data collection)
- Mobile Phones /Smartphones
- Telephone – Voice recognition
- Bespoke devices
Compared to paper-based COA, eCOAs may lead to less administrative burden, high patient acceptance, higher levels of administrations, avoidance of secondary data entry errors, easier implementation of skip patterns and more accurate and complete data.
