What is REDCap? REDCap (Research Electronic Data Capture) is a web-based application used to create forms and manage databases in order to support data capture and surveys for research studies. (Research Electronic Data Capture) is a web based application used to create and manage databases and surveys in order to support data capture for research studies.

What is REDCap? REDCap Form Types Survey Intended for a subject or participant Can be anonymous Data Capture Intended for a research team member or collaborator

Who can use REDCap? Any University of Iowa investigator or research team can use REDCap. You can log into REDCap via: Video training modules are available via: p/index.php?action=training

Why are people choosing REDCap over Excel and Access? Access to REDCap is authenticated  Uses University of Iowa LDAP HawkID and password Secure hosting and regular data backups  Data backups, software upgrades, and system maintenance are handled automatically by ICTS  Data is secured via SSL Allows multi-site access  Research teams can input data simultaneously, from across the hall or across the country

Additional reasons why to choose REDCap over Excel and Access Researchers can build databases rapidly  Any user can login and start a project Research teams have autonomy  Create a new database or survey  Assign user permissions and roles  Done in accordance with the IRB  Granting rights for data import and export

REDCap Web Interface Form creation and data entry are easy in the web interface

REDCap Data Collection Classic Data Collection Form intended to be used for a single time period (ask the questions once) Longitudinal Data Collection A form can be used for multiple time periods  Vitals at initial visit, 30 days, 60 days, etc. Same form used for all time periods Calendar used to schedule subject visits

REDCap Features Researchers can make modifications to their database at any time during the study  Draft mode (design phase)  Production mode (live data collection) Branching logic is supported Calculated fields are supported Researchers can copy databases

REDCap Confidential Data Identified data Research teams can easily mark identified data in the interface and create access limits on those fields that include identifying information

REDCap Data Features Researchers choose what people and groups have access to: Data export, both identified and de- identified Data export & import capability User rights management View reports View logging Data comparison

REDCap Report Generation Reports can be: Generated on the fly Any field can be included on a report Sort order and column order specified Saved and used over and over within the interface Limited to certain users

REDCap File Sharing File Repository Placing a project in production  file repository automatically snapshots your data dictionary with each production change Other project-specific files can be stored here  E.g. consent form template, SOP Files can be securely shared with project members and non project members  Via and a token.

REDCap Graphing Graphics Data View & Stats

REDCap Data Quality Control Data Comparison Tool  Used to compare two records in a project Data Quality Tool  Missing Values  Validation Errors (incorrect or out of range)  Outliers  Hidden fields with values  Multiple choice fields with invalid data

REDCap Features Double Data Entry Intended for 2 persons entering data from a form Each are independent DDE1 and DDE2 roles are assigned to 2 different people A reviewer reconciles Reviewer role is assigned to a third person (need an admin to enable)

REDCap Features Parent Databases Allows for a parent database with things such as contact information and demographics information Parents can have many children Child databases Child databases inherit information from parent databases Children have only 1 parent (need an admin to enable)

REDCap Extensions API Allows external applications to connect to REDCap Used to retrieve or modify data in REDCap (via data export and import) Admin needs to enable Plugins For web developers wanting to use REDCap

REDCap Analysis Researchers can export data to a variety of statistical analysis packages (SPSS, SAS, Stata, R or Excel)  Researchers can grant or restrict access to export data for analysis  Data exports are customizable, including all or some of the data forms and fields  Exports can include identified or only de- identified data depending on user and group rights

REDCap Auditing Data logging records information: Who changed the data What data was accessed When these events occurred

REDCap System Security Things the IRB will want to know Physical Security  Primary Data – HCIS Pomerantz Data Center  Data backups – ITS Lindquist Data Center Operating System Security  HawkID based logins  Data encrypted at rest  Remote system logging  Configuration and Change Management

REDCap Data Backups Backups are always At rest --This means even the system admins who have access to the hard drive are unable to read On the fly – this means if someone where listening to network transmission they would be unable to decipher the information Copies of data replicated to remote data center every 15 minutes 100+ point in time copies of data available at any time Disaster recovery strategy has been tested without data loss
