Castor EDC 2019.3 release notes

Main features & improvements


  • It is now possible to set up a reminder for a survey package. This can be done when creating/editing the survey package in the structure tab. This is a generic setting for the survey package and will always be applied when an invitation is sent for that survey package. The reminder can be set for up to 99 days after the invitation was sent.

  • Survey respondents can now choose different languages for surveys. The complete list of languages is now: English, Dutch, French, German, Spanish, Portuguese and Italian. The survey translations apply to buttons and messages. Creating a translated version of the actual questions in the survey will need to be done by the person creating the questionnaire.

Study creation

  • The Create New Study form has been renewed

    • Study ID, which was only used within the URL of the study has been removed. Trial registry ID which can be used for documentation outside of Castor EDC is still available.

    • A selection of templates has been added to the Create New Study form, these can be used to build a study more quickly.

Study structure & form builder

  • A new field type has been added: Add Survey Button. This button can be used to create a survey invitation directly from data entry and works similarly to the Add Report Button.

  • It is now possible to apply bold (**bold**), italic (_italic_) and underline (___underline___)text to option names,  in the same way as this works for field labels and field info text.

Data entry

  • The design of dropdown fields has been updated. Additionally, dropdown fields with a large number of options (>250) turn into a search box instead of loading all the options which improves data entry performance for studies with large option groups.

  • When a record has been randomized, it is no longer possible to change the data for a field used for stratification or its parent. 


  • The export for comments now has additional info: current value of the field, which type of form the field is located on (study/report) and the report name if applicable.

  • The survey variable list in a data export has been updated to include the same info about variables as the study variable list and report variable list.


  • The endpoint /study/{study_id}/surveypackageinstance/{survey_package_instance_id} now returns the survey instances that belong to the survey package instance.

Bug fixes & minor improvements

  • When creating a custom column in study settings, you can now choose whether to display option labels or option values for radio button/checkbox/dropdown fields

  • Added information to the server filter on the My Studies page.

  • On mobile devices the navigation pane now closes when the user clicks on any tab.

  • Updated My Studies page to show archived studies as disabled, even when hovering over.

  • When randomization in study settings is enabled, a recommendation is shown to enable GCP.

  • Small visual updates for survey data entry to allow for validated EQ5D surveys on mobile devices.

  • The date picker in the FHIR importer automatically updated all steps when a date for one step was selected. In some cases this is not helpful and therefore it has been disabled.

  • Fixed a bug where users were not able to register with apostrophes in email address.

  • Fixed a bug where studies with a very large number of fields could show progress as 100% while there were still incomplete fields.

  • Fixed a bug where uploading a file to an upload field which was on a verified or signed step resulted in no action.
