The Registry's Steering Committee will conduct a formal review of proposals of investigator-driven research projects and will provide recommendations to the PI. The PI, under the Registry's current protocol, must grant final approval for all studies conducted using medical information contained within the Registry. Such approvals shall be obtained prior to providing investigator information from the Registry; shall be based upon considerations of scientific quality and validity; shall be granted only for research studies related to PE or related hypertensive disorders of pregnancy; and shall be documented. Prior to provision of data to any investigator, the information shall be de-identified. The Registry shall require investigators to obtain IRB approval prior to its provision of de-identified information to the investigator.
