Extract collects data with REDCap (Research Electronic Data Capture).  The project includes multiple data collection forms, including patient demographics, baseline characteristics, specific lead information, and extraction-related procedural outcomes.

REDCap is a mature, secure web application for building and managing online surveys and databases. Using REDCap's stream-lined process for rapidly developing projects, you may create and design projects.  Both surveys and databases (or a mixture of the two) can be built using these methods.  REDCap provides automated export procedures for seamless data downloads to Excel and common statistical packages (SPSS, SAS, Stata, R), as well as a built-in project calendar, a scheduling module, ad hoc reporting tools, and advanced features, such as branching logic, file uploading, and calculated fields.
