Due to the lengthy approval period, it makes sense to minimize the implementation phase of a clinical study to the greatest extent possible. In recent years, Electronic Data Capture (EDC) and the digitization of clinical trials have shown effective techniques. Increasingly, study data are collected digitally rather than on paper and are kept in an online database utilizing electronic case report forms (eCRF). However, what advantages does the usage of eCRFs in clinical studies present?

High-security thanks to accessing limits and compliance with particular criteria: The sensitivity of the data collected regarding patients and drugs used in a trial requires specific protection. eCRFs have the benefit that data access can be readily restricted to authorized users, for instance, through password protection. Furthermore, a single, integrated system ensures fast retrieval and avoids data loss. An ISO 27001 ("Information Security Management System") and HIPAA (Health Insurance Portability and Accountability Act)-compliant data storage system, as well as an SSL certificate that is constantly up to date, are required preconditions. A second server is needed to store redundant data to ensure long-term data availability.

In contrast to manually copying test forms, digital data storage may be set up fast, securely, and automatically so that the data is always accessible, even if a server fails. To safeguard patients, data protection authorities also demand pseudonymization of patient data. This ensures that the gathered test forms may only be assigned to specific test subjects using key access to a restricted number of individuals. This means that highly sensitive data is only exposed to a small set of persons that need it and is segregated from the rest of the study data. Unlike paper-based systems, where this requires a substantial amount of additional administrative effort, pseudonymization is automatic in eCRFs.

Cost savings: The typical cost of drug research and the associated conduct of clinical trials is in the single-digit billions. By replacing paper-based systems with digital technologies, prices can be decreased. This is evident in the review of test forms, as the patient data is automatically transmitted to the system, eliminating the time spent interpreting illegible handwriting, manually transferring data, and verifying the transfer.
