The Department of Public Health shall establish a registry of data on traumatic brain injury patients. Each hospital, as defined in § 19a-490, shall make available to the registry such data concerning each traumatic brain injury patient admitted to such hospital as the Commissioner of Public Health shall require by regulations adopted in accordance with chapter 54. The data contained in such registry may be used by the department and authorized researchers as specified in such regulations, provided personally identifiable information in such registry concerning any such traumatic brain injury patient shall be held confidential pursuant to § 19a-25. The data contained in the registry shall not be subject to disclosure under the Freedom of Information Act, as defined in § 1-200. The commissioner may enter into a contract with a nonprofit association in this state concerned with the prevention and treatment of brain injuries to provide for the implementation and administration of the registry established pursuant to this section.
