REDCap News & Updates

REDCap News & Updates

As you may know, the CTSI of Southeast Wisconsin has administered REDCap for over 12 years. We have over 580 research projects, and hundreds of quality improvement and administrative projects, with an active user base of over 1,800 individual users. You also may know that REDCap continually develops more and more useful features.

Feature in Focus: Image Maps

The feature we are highlighting this quarter is called Image Maps. This REDCap module replaces an input, radio, or checkbox field with an image that users can interact with to select one or more options. Specific applications include a body map (with over 70 body regions), a smile scale from 1-7 with facial expressions, and 3 representations of teeth and teeth surfaces.

Future versions will allow administrators and users to add additional maps via the module configuration. The module is tied to questions via the @IMAGEMAP action tag and the name of one of the pre-defined image maps, for example, @IMAGEMAP=PAINMAP_FEMALE.

Usage

 This module is now available in all projects by default and can be utilized by users with Project Design & Setup rights. To begin using simply add a new field of type Text Box as you normally would with label, variable name, etc., then add one of the lines below in the Action Tags section in the Online Designer, or column R (Annotations) in the data dictionary.

Action Tag

@IMAGEMAP=PAINMAP_MALE
@IMAGEMAP=PAINMAP_FEMALE
@IMAGEMAP=SMILE_SCALE
@IMAGEMAP=SINGLE_TOOTH
@IMAGEMAP=TEETH_SURFACE
@IMAGEMAP=TEETH
@IMAGEMAP=PIRADS
@IMAGEMAP=BEES

Each region of an image is associated with a key; for example, the “Ankle (front-left)” of the female body diagram is linked to the key “f34.” To find a particular key for a body part, please refer to the html files (map files) located in the folder maps. After selecting multiple body parts, the field containing the action tag @IMAGEMAP will have as value a string of comma-separated keys, e.g. “f36,f17,f18,f21.” Similarly, if using the faces diagram, the field containing the action tag (i.e., @IMAGEMAP=SMILE_SCALE) will have the value corresponding to the face clicked, which ranges from 1 to 7.

Please contact Mark Oium (redcapsupportctsi@mcw.edu) with any questions.
