The EDC system changes the previous paper-based clinical research, which was characterized by slow data collection, lag in data verification, difficulty in data cleaning, long trial cycle and low data quality. It ensures the quality of clinical trial data. It effectively shortens the clinical research cycle and buys valuable time for drug launch. Data management is one of the key links to ensure the quality of clinical research data. Effective collection and management of clinical research data ensures data integrity, reliability and accuracy.

Biozhi EDC system ensures the security of the entire system through authority control, electronic signatures and audit traces. At the same time, it ensures the maximum sharing of data information through the standardized structure of data and multi-role verification of data quality. It also reduces data management and maintenance costs, supports multiple usage modes such as web and mobile phones, supports multiple data quality verification schemes, supports online summary reports and data statistics, and ensures data accuracy and standardization.
