Key features offered by REDCap

Smartphone application with offline data collection

Apple ApplicationAndroid ApplicationREDCap offers a smartphone application for both Android and iOS smartphones and tablets. This application allows for remote collection of data even without an active internet connection. Once a REDCap project has been created in REDCap, a smart device can be connected to the project by scanning a QR Code. 

Once a device has been connected to the project, administrators can provide devices with identifying nicknames, see all activity undertaken by a particular device and if necessary, block devices.

Online DesignerEasily built online surveys and databases

REDCap provides a clean out of the box interface to create easy to use and professional surveys and data collection instruments with an online designer tool. The easy-to-use tool provides users with a number of options to gather different types of data such as; multiple-choice answers, free text fields, true/false statements, and more; easily through an online form. There is even the functionality to upload a file or have a form digitally signed by a participant or data collector.

There also exists the ability to utitlise more advanced fields when creating surveys such as calculated fields and branching logic.

If using REDCap as a survey tool, it is possible to manage a list of survey participants and utilize the application to directly send the survey to participants in a number of different methods. These options include the option to email direct links to participants in order to take the survey. This provides the ability to track responses for individual participants. Alternatively, the survey can be exposed to the public for anonymous responses using either a direct URL link, embedding into a webpage or a QR Code.

Data Analysis

Cholesterol ExampleOnce data has been created, REDCap allows users a number of ways to use their data. There is a powerful export tool that allows for data to be downloaded to Microsoft Excel (CSV) as well as SPSS, SAS, R and Stata statistical software packages. There are also a number of tools built in to the application that allow a user to analyse the data without the need to extract it from the application first.

These in built analysis tools allow a user to;

  • Compare 2 separate data sets against each other
  • Plot all numerical data from a particular query
  • Chart number of responses to multiple choice answers
  • View information about results such as standard deviation, median, mean etc.
  • Use data quality tools to find
    • Data that is a statistical outlier
    • Data that has not been entered for a field

User Friendly Interface

REDCap Home PageREDCap provides users with a clean and intuitive interface to navigate to different parts of your project. In particular, the project home landing page allows users to manage all aspects of their projects easily from the one screen. 

From this page, you are able to access key functions for the project with quick links to export data, create a report, check data quality, user rights, online designer and the possibility to copy the entire project to a new project instance.

A number of these options also exist in the side navigation bar which is present on every page you visit. This navigation bar also provides quick shortcuts to other functionality like the file repository, mobile application setup, data import and comparison tools as well as audit logging.

The project setup page provides a clear start to finish checklist style view that walks you through the project creation process in order to move from conception to production-level survey/database in less than one day. This includes, creation of surveys/data-collection instruments, defining events, repeating surveys and permissions and rights of individual users before moving on to testing and publishing your project for use.
