13 ), while an indication for resection after a single disabling SH is seen as more controversial (class IIb evidence, level C 13 ). Clinical decision-making and selection for BSCM surgery requires considering more variables than merely the history and frequency of SHs. Therefore, we sought to perform a survey using the Delphi method on multiple aspects of surgical treatment and management of BSCM among international experts to investigate the extent of current clinical consensus that could be achieved and identify questions and ambiguities that may drive future

this process until consensus is achieved. Here, we use this method to create consensus-based procedural triage protocols and checklists during the COVID-19 pandemic. Methods A multidisciplinary perioperative committee (MDPC) was tasked with the creation of a triage system and management protocols for patients requiring urgent and emergent procedures and surgeries during the COVID-19 pandemic. The MDPC is composed of 26 leaders from 10 academic departments, including 7 department chairpersons, the chief medical officer, the chief operating officer, infection control

surveillance practice patterns and the dearth of supporting literature, the Delphi method was proposed to identify areas of consensus and opportunities for further research. The Delphi technique uses a structured series of anonymous questionnaires to build consensus among a group of topic experts. In particular, the modified Delphi method, which culminates in a face-to-face meeting to facilitate open discussion and modification of the consensus statements, has been successfully used to address a range of pediatric neurosurgical topics, including pediatric cervical spine

Pediatric and Congenital Heart Disease for complications after cardiac surgery for congenital heart disease, including consensus definitions. 2 There are, however, no standardized or consensus-driven definitions for complications or adverse events in pediatric neurosurgery. We recently reported the incidence of complications from all surgical procedures in a single pediatric neurosurgical center prospectively over a 2-year period. 12 It became clear that broadening this approach to other centers would require standardized definitions to ensure accuracy and

Formal consensus guidelines have been developed to guide the treatment of intact vertebral bodies. 6 The practice of spinal SBRT in postoperative patients is similarly growing, and data are emerging to suggest

N eurocritical care of patients with aneurysmal subarachnoid hemorrhage (aSAH) requires collaborative efforts from multiple disciplines that treat and manage the consequences of both the primary hemorrhage and the secondary brain injury that may occur following rupture. 2 , 66 Elevated intracranial pressure (ICP) has been recognized as a consequence of aSAH that may contribute to a patient’s clinical decline. Despite significant advances in aSAH clinical research, there are no consensus guidelines devoted specifically to the management of elevated ICP in the

input is invited. An effort is made to obtain input from all members, and interruptions are avoided unless the discussion goes off topic or is excessive in the view of the chair, who then interjects. At the close of discussion of the topic, 1 member provides a summary, and an action item is proposed. At this point, a consensus is sought and any significant objection results in additional discussion or re-tabling of the issue. Two committee members may be assigned to gather further data, or communicate with academic or industry sources, and report back to the committee

✓ More refereed publications on sports-related concussion have appeared since 2000 than in all previous years combined. Three international consensus statements, documents from the National Athletic Trainers' Association (NATA) and the American College of Sports Medicine (ACSM), and entire issues of the Clinical Journal of Sport Medicine and the Journal of Athletic Training have been devoted to this subject. The object of this article is to critique the consensus statements and NATA and ACSM documents, pointing out areas of controversy.
