When a triggering event takes place for a trial, the system evaluates whether that trial is eligible for a Twitter announcement. If the trial is eligible, the system submits a tweet with the following components:

• Base text: A new NCI-sponsored <hashtags> study is now accepting patients. <reference_url>
• A shortened reference URL for the trial record on cancer.gov.
• One or more hashtags, such as #coloncancer or #lymphoma, based on the body sites assigned to the trial.

Triggering events include:

• Trial Status change for a Complete trial

• Participating Site Status change for an Abbreviated (Industrial) trial

• Processing Status change for any trial

• The addition of an NCT ID to any trial 

The system submits a tweet only when all of the following conditions have been met:

• The trial's Processing Status is Abstraction Verified Response or Abstraction Verified no Response.
• The trial meets one of the following conditions:
  
  • For Complete trials, the Trial Status is Active or Enrolling by Invitation.
  • For Abbreviated (Industrial) trials, the Participating Site Status is Active or Enrolling by Invitation.
• A tweet has not been sent for the trial.
• The trial is an original submission. (That is, it is not an amendment.)
• The trial has an NCT ID.
• The trial is not flagged with the flag reason “Do not submit tweets.”
• The trial has been submitted to cancer.gov.
