Impact of Selection Criteria on Recruitment in an Interventional Stroke Trial

Abstract

We describe frequencies of selection criteria in a typical cohort of patients suffering from acute cerebrovascular events, and their cumulative impact. These data may help to better understand recruitment limitations and allow designing future trials more effectively. Ability to consent especially is a major contributor to trial exclusion, strongly interfering with the targeted trial population of ischemic stroke. Tentative prescreening phases before site or trial initiation should be considered. No predictive statistical models of recruitment have been established so far.
