All study settings can be found in the tab 'Settings', subtab 'Study'. This tab is available for the study admin(s) with 'Manage Settings' rights. Here we describe all the settings that you can adjust.

General settings

The first category is 'General':

Invoice details

If your study is sponsored by a commercial entity, then you will need a billing code. Contact us to get a quote for your study and a billing code. If the study is initiated by an institute that has a license for Castor, you will also need to enter a billing code. 

If you are not using a billing code, the Invoice section is where you should enter all the billing details for this study, including the address that the invoice for the study will be sent to. Please specify the 'Project number' to ensure the invoice gets declared for the right project:


Adding a billing code

If you are using a billing code, select 'Yes' in the dropdown menu 'Billing code' and add your billing code to the designated field, then save your settings at the bottom of the page:

Good Clinical Practice

Next is the 'GCP" section, in which you can enable GCP for your study and set the data verification types to be used:

Confirm changes: This will require the user to enter a reason for change for any data edits. 

Verification types: Source Data Verification is by default included in the verification types. You can use this if you have Monitoring enabled for your study. You can also add other verification types. 

Other


  • Record IDs: choose how you want IDs for new records to be generated, see Settings - Record ID options for more information.
  • Clear inapplicable child fields: when set to 'Yes', this setting clears the inapplicable child fields when a parent field is changed. For example: when changing the gender from female to male, all pregnancy fields are cleared, because these were made dependent on the female gender. The system will always ask for confirmation before existing data values are cleared: 

Note 1: This setting is only for study forms and reports. In surveys, inapplicable child fields are always cleared, regardless of this setting. 

Note 2: Changing this setting after you have started the collection of data will not clear inapplicable fields retroactively.

  • Enable beta features: when set to yes this setting enables the Automation Engine functionality.
  • Enforce 2FA: two factor authentication can now be enforced on the study level - when set to 'Yes', users in this study must use two factor authentication for their Castor account to be able to access the study. 
  • Only show records with exact match when searching: this setting will make records invisible in the Records tab. Retrieving a record will only be possible when the exact record ID is entered in the search box.
  • Signature Statement: This statement will be presented when applying a signature. So, by signing the phase or step, you declare what is written in the signature. Note: after the study has gone live, it is no longer possible to edit the signature.

  • Record overview custom columns: add and delete custom columns for the Records tab.
  • IP white list: whitelist a range of IP addresses. The IP addresses should be in the CIDR format. When this feature is enabled, the study is only accessible from the IP addresses on the list.
