REDCap vs REDCap Cloud

REDCap is a secure web application for creating and managing online surveys and databases for research studies and operations. Projects can be designed in the application or populated by uploading a data dictionary prepared offline in Microsoft Excel. Research tools include multi-site access, user-managed project access, audit trails, calendars, scheduling, reporting, branching logic, file uploads, and calculated fields. Data exports include Excel, PDF, and common statistical packages such as SPSS, SAS, Stata, and R. Its CDIS feature can retrieve selected structured information from EHRs such as Epic and Cerner through FHIR and OAuth2, but an administrator must enable it. The companion mobile app supports offline collection on iPhone, iPad, and Android phones or tablets and requires an account at a REDCap partner institution. REDCap is server software that an organization's IT staff installs and maintains. Requirements include PHP 8.0 or higher, a MySQL-compatible database, and an SMTP email server; Microsoft SQL Server is incompatible. Eligible nonprofits can obtain a consortium license at no charge. A demonstration account costs nothing for one-time access lasting three days, which cannot be extended.
