Defining "Community" and "Consultation" for Emergency Research that Requires an Exception from Informed Consent.

Trauma care requires rapid interventions to optimize the chances for survival. Many patients are either in shock or unconscious and are, therefore, unable to provide informed consent even for standard procedures. Research-related interventions must similarly be initiated rapidly with no opportunity to obtain consent from the patient or the patient's legally authorized representative. Federal regulations allow for an exception from informed consent in these circumstances once the investigators complete a process of community consultation and public disclosure. The challenges for investigators include how to define the at-risk community for enrollment in the trial and then how to adequately reach out to that community. Many approaches have been used, with varying success. What constitutes true engagement with the community needs to be further explored. [ABSTRACT FROM AUTHOR]
