We do have a scheduled post-deployment enhanced screening that occurs between three and six months after a six-month deployment. We don't do specific screening while they are in theatre. They are aware and have access to health care providers should they start to have some symptoms that they are concerned about, so they can come forward to see us there.
As they are leaving theatre, we start to get them ready with some briefings on the changes that they may experience as they're returning home. Some of that talks about the potential for mental health impacts. Then again, at three to six months after they're home, we go through an individual one-on-one assessment with them to see whether or not they have any follow-up mental health impacts.
We've been finding that about 50% of the people who screen positive for potential mental health effects in that post-deployment screening have already come in and sought care before that screening has occurred, so that's been a good sign for us that some of our education and messaging on mental health is working.
