CRF access category management
When designing a CRF in SD, you can arrange for your sensitive data to be protected upon data collection in EDC. For this, you can blind as well as restrict editing of forms and separate questions on those forms. Applying general blinding or restricting edits to a form or question requires you to define an access category.
An access category determines the level of information concealment or a user's editing capacity to a form or question. Different access categories are helpful when dealing with complex interventions or multifaceted data collection because you can provide specific users or groups of users with permission to see or edit certain data pieces according to their qualifications.
During the form configuration or question management in SD, you can set up an access category upon assigning either of the following access types:
-
Restricted Edit: only the user group given restricted data editing permission can perform data entry in EDC.
-
General Blind: only the user group with unblinded access category can review or edit the blinded data of specific forms.
After defining access categories for forms and questions during the CRF design, these categories are stored at the study level.

You cannot manually add new access categories since they can be added only when you create or edit a form. However, at the study level, you can perform actions with the existing categories as explained in the following sections.

After defining access categories for forms and questions, you can find their complete list at the study level, where you can edit names for existing categories for consistency, compliance, or other needs. The changes are automatically applied to general blinding settings of all forms and questions where these categories are used.

The complete list of all access categories applied to any CRFs or questions can be found at the study level. From here, you can delete existing categories and so, remove blinding or editing restrictions from all the forms and questions where they were applied. This helps you quickly lift the restrictions without the need to do so form by form.
