Item Establishing a core outcome set for blunt cerebrovascular injury: an EAST modified Delphi method consensus study(BMJ, 2023-06-15) Ziesmann, Markus; Byerly, Saskya; Yeh, Daniel Dante; Boltz, Melissa; Gelbard, Rondi; Haut, Elliott R.; Smith, Jason W.; Stein, Deborah M.; Zarzaur, Ben L.; Bensard, Denis D.; Biffl, Walter L.; Boyd, April; Brommeland, Tor; Burlew, Clay Cothren; Fabian, Timothy; Lauerman, Margaret; Leichtle, Stefan; Moore, Ernest E.; Timmons, Shelly; Vogt, Kelly; Nahmias, Jeffry; Surgery, School of MedicineObjectives: 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 <15% of scores receiving 1 to 3. Feedback and aggregate data were shared between rounds, and four rounds of deliberation were performed to re-evaluate the variables not achieving predefined consensus criteria. Results: From an initial panel of 15 experts, 12 (80%) completed all rounds. A total of 22 items were considered, with 9 items achieving consensus for inclusion as core outcomes: incidence of postadmission symptom onset, overall stroke incidence, stroke incidence stratified by type and by treatment category, stroke incidence prior to treatment initiation, time to stroke, overall mortality, bleeding complications, and injury progression on radiographic follow-up. The panel further identified four non-outcome items of high importance for reporting: time to BCVI diagnosis, use of standardized screening tool, duration of treatment, and type of therapy used. Conclusion: Through a well-accepted iterative survey consensus process, content experts have defined a COS to guide future research on BCVI. This COS will be a valuable tool for researchers seeking to perform new BCVI research and will allow future projects to generate data suitable for pooled statistical analysis with enhanced statistical power.Item A management algorithm for patients with intracranial pressure monitoring: the Seattle International Severe Traumatic Brain Injury Consensus Conference (SIBICC)(Springer, 2019-12-01) Hawryluk, Gregory W.

Methods We used a Delphi-method-based consensus approach to address management of sTBI patients undergoing intracranial pressure (ICP) monitoring. Forty-two experienced, clinically active sTBI specialists from six continents comprised the panel. Eight surveys iterated queries and comments. An in-person meeting included whole- and small-group discussions and blinded voting. Consensus required 80% agreement. We developed heatmaps based on a traffic-light model where panelists’ decision tendencies were the focus of recommendations. Results We provide comprehensive algorithms for ICP-monitor-based adult sTBI management. Consensus established 18 interventions as fundamental and ten treatments not to be used. We provide a three-tier algorithm for treating elevated ICP. Treatments within a tier are considered empirically equivalent. Higher tiers involve higher risk therapies. Tiers 1, 2, and 3 include 10, 4, and 3 interventions, respectively. We include inter-tier considerations, and recommendations for critical neuroworsening to assist the recognition and treatment of declining patients. Novel elements include guidance for autoregulation-based ICP treatment based on MAP Challenge results, and two heatmaps to guide (1) ICP-monitor removal and (2) consideration of sedation holidays for neurological examination. Conclusions Our modern and comprehensive sTBI-management protocol is designed to assist clinicians managing sTBI patients monitored with ICP-monitors alone. Consensus-based (class III evidence), it provides management recommendations based on combined expert opinion. It reflects neither a standard-of-care nor a substitute for thoughtful individualized management.
