Developing regulatory-compliant electronic case report forms for clinical trials: experience with the demand trial.

The use of electronic case report forms (CRF) to gather data in randomized clinical trials has grown to progressively replace paper-based forms. Computerized form designs must ensure the same data quality expected of paper CRF, by following Good Clinical Practice rules. Electronic data capture (EDC) tools must also comply with applicable statutory and regulatory requirements. Here the authors focus on the development of computerized systems for clinical trials implementing FDA and EU recommendations and regulations, and describe a laptop-based electronic CRF used in a randomized, multicenter clinical trial.
