This profile represents the constraints applied to the DeviceUseStatement resource for the purpose of this guide. A device used by or implanted on the patient is described in the hospital discharge report as an instance of a Device resource constrained by this profile.

Usages:

- Use this Profile: Bundle (EPS)
- Refer to this Profile: Composition (EPS)
