Trials are conducted in participating sites. Information about the site (organization), investigator(s), and primary contacts (if a central contact is not provided) must be abstracted. Information about participating sites can be included in the protocol document or in the Participating Sites document.

The system assigns investigators and primary contacts a status code that corresponds to the person’s/role’s curation status.

    CTRP validates all status transitions when a trial status record is saved. If a status transition is added or updated which does not conform to the rules provided in Trial Status Transitions, CTRP displays errors and/or warnings. Warnings indicate that correcting the transition in the trial status record is optional. However, Errors indicate that correcting the transition in the trial status record is required. All transitions can be updated in the Participating Sites Status History window. The trial cannot be checked in until all status transition errors have been resolved. For a comprehensive matrix of valid transitions, see Trial and Participating Sites Status Transition Rules

  12. Select the Contact tab.

    A Participating Site must be linked to the trial before abstracting the site PI and contact information. A contact can be added by providing a person’s name (i.e., someone who is associated with the trial itself), or a generic contact can be added (i.e., someone who is associated with the site but not necessarily the trial) by providing a person’s title (functional role). Both types of contacts can not be added in the same record. An abstraction cannot be completed if a primary contact is not assigned.


    If an investigator is designated as the primary contact (on the Investigators tab), the investigator's name is displayed on the Contact tab.

  13. On the Contact tab, next to the First Name field, select Look Up and search for the contact person’s name by following the instructions in Searching for Persons
