The electronic case report form (eCRF) is a tool to gather all the data from different electronic and paper based systems. It is important because it makes it possible to assemble and organize diverse data in a manner that fulfills the study protocol and allows the data to be reviewed and analyzed. Data from clinical studies must be integrated for FDA submission and it is beneficial if the data is collected in a standardized format from the start. Standard forms mean simplified electronic data capture (EDC) system training for in-house and site staff. They also streamline the flow of data from collection through submission, whether a single or multi-site study. Data exchange between partners and providers is facilitated, and reviewers can then work with the data with less preparation time.
