The MOST-consent study: Patient-driven consent for a multi-center adaptive trial in acute ischemic stroke

Clinical trials to improve stroke treatments heighten the consent challenges that arise in any clinical trial. Strokes happen suddenly, and treatment must begin within three hours. Patients must be enrolled in a clinical trial before they are transferred to specialized stroke centers serving as study sites. Thus the consent process must be done remotely, often by surrogates who are communicating with the clinical trialists at the study site by telephone or videoconference.
