What is REDCap?
• Web-based software for data entry
• Originally for clinical research, but usable in other domains
• Developed by Vanderbilt. – 267 institutional partners (as of 16-Sep-2011)– http://www.project-redcap.org

REDCap Consortium
• Worldwide: 21,160 studies; 30,060 end-users

Who already uses REDCap?
• Statistics (as of 16-Sep-2011):– 257 dbs (79 production, 76 development, 2 inactive, 18 archived, 82 practice)– 294 active users– 930 data entry forms; 23,288 data fields; 48,025 data records
• IU School of Medicine – many departments, divisions/sections; IU School of Nursing; IU School of Dentistry; Indiana CTSI; Purdue University; Regenstrief Institute; VA Medical Center; IU Health – Methodist; Wishard Health Services; Rehabilitation Hospital of Indiana

Managing data on a small budget
• Custom programming is time-consuming and expensive
• Excel is quick and easy, but leads to data problems
Imagine creating a database with the click of a button

What do people like about Excel?
• It Just Works / It’s Familiar– It’s very easy to get going. Problems only come later
• You don’t have to wait for anyone else– You don’t have to get IT to do it for you

What problems occur with Excel?
• Version Control– Who’s got the latest file?– Who changed what?– Has any of the data been lost?
• Data Consistency– How many ways can you spell Mississippi?– Is -37 an allowed value?– Is ‘Yes’ the same as ‘1’?

How can REDCap help?
• Get started fast– Entry forms, reports, etc. created automatically from a data
dictionary.– Data dictionary created by anyone – from a spreadsheet or GUI
• Create data Consistency from the beginning– Apply type checking, range checking; Use coded/standard
responses.– Begin with the end in mind – what will need to be analyzed?

Demonstration: Start to Finish

• Create a database
• Data Entry
• Data Export
ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH
www.indianactsi.org
What data can REDCap manage?
• Numbers, text, dates, files, lists (radio/checkbox/multiple), branching, calculations
• Simple Schemas– Designed for a single table of information
– 1:many relationship is possible, but tedious to create
– Many:many only possible by using multiple REDCap databases.
• Electronic Protected Health Information (ePHI)– IU has put in place appropriate administrative, technical, and
physical controls to protect data in accordance with the HIPAA security rule
ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH
www.indianactsi.org
What data is not allowed in REDCap?
• When storing ePHI, you remain responsible for privacy, security, and compliance. You need IRB approval and a Data Management Plan. Technical and physical controls are provided, but you remain responsible for administrative controls.
• REDCap is for use only in support of academic research. Do NOT use REDCap for other uses, for instance to store official university business data, patient care data, or electronic health records (EHRs).

What else can REDCap do?
• Longitudinal data; Scheduling; Online reports; Simple online analysis; Data deidentification; Full audit trails and logging; Double data entry; Data access groups; Application Programmer Interface (API); Data Transfer Services
• REDCap Survey– More secure and fewer limits than Survey Monkey
• REDCap 4.0 – merger of REDCap and REDCap Survey; dozens of improvements.

Advanced Functions
• Double Data Entry– Quality assurance for data entry – compare data entry by two
different people
• Data Access Groups– Allow people at multiple sites to contribute to the same database,
without seeing other people’s data.

Advanced Functions
• Application Programmer Interface (API)– Web Services interface for reading and writing data and metadata
• Data Transfer Service– Separate software service, using the API, for incorporating data
from other databases (typically a relational database) using an adjudication process
– Commonly used to incorporate data from medical records systems

Where is REDCap?
• Hosted on a physical server in the Bloomington Data Center
• Supported by the Indiana Clinical Translational Sciences Institute (CTSI) via a collaboration of staff from the Biostatistics Department and from the Advanced IT Core of the IU School of Medicine, which is part of Research Technologies/UITS
