REDCap

REDCap (Research Electronic Data Capture) is fundamentally an anomaly in the massive, highly commercialized EDC software market. Developed by Vanderbilt University, REDCap is not a commercial SaaS product sold by a massive corporation; it is a highly secure web application for building and managing online surveys and databases, distributed at absolutely no cost to institutional partners via the REDCap Consortium. Because it is free for non-profit organizations, it is the absolute, undisputed default EDC platform for virtually every major university, academic medical center, and research hospital in the world. The core philosophy of REDCap is maximum autonomy for the researcher. A university IT department installs REDCap on their own secure local servers. Researchers can then log in and build massive, complex longitudinal databases to track patient outcomes over years, or launch global, multi-site surveys. The form builder is incredibly straightforward, and power users can define complex calculated fields and branching logic. Because the data resides on the institution's own servers, it completely bypasses the massive legal hurdles associated with sending sensitive HIPAA-protected health data to a commercial third-party cloud vendor. While it lacks the massive, highly specialized clinical modules (like RTSM or complex medical coding dictionaries) found in enterprise tools like Medidata, REDCap is phenomenally powerful for observational studies, registries, and investigator-initiated trials. Its API is incredibly robust, allowing academic data scientists to easily pull data directly into R or Python for complex statistical analysis. For the massive ecosystem of non-commercial academic research, REDCap is simply an indispensable public good.
