Final answer:
The statement is false; the American College of Surgeons determines case definitions for trauma registries, not individual healthcare organizations.
Step-by-step explanation:
The statement in question is that case definition for trauma registries is determined by individual healthcare organizations. This statement is a false statement because the case definition for trauma registries is actually determined by the American College of Surgeons. Organizations like the Joint Commission and state health departments may have input or additional requirements, but they do not define the case definition for trauma registries. The American College of Surgeons through the Committee on Trauma establishes standards for trauma care, and their guidelines are widely adopted as a means to ensure consistency and quality in trauma care and registries.
