Establishing a core outcome set for blunt cerebrovascular injury: an EAST modified Delphi method consensus study

Objectives Our understanding of blunt cerebrovascular injury (BCVI) has changed significantly in recent decades, resulting in a heterogeneous description of diagnosis, treatment, and outcomes in the literature which is not suitable for data pooling. Therefore, we endeavored to develop a core outcome set (COS) to help guide future BCVI research and overcome the challenge of heterogeneous outcomes reporting.Methods After a review of landmark BCVI publications, content experts were invited to participate in a modified Delphi study. For round 1, participants submitted a list of proposed core outcomes. In subsequent rounds, panelists used a 9-point Likert scale to score the proposed outcomes for importance. Core outcomes consensus was defined as >70% of scores receiving 7 to 9 and
