Results A total of 130 patient-proxy pairs were involved in the study. Agreement of EQ-5D-3L-Y responses between the self-report and proxy version was good for "Feeling worried/sad/unhappy" dimension, and very good for other dimensions. Poor agreement in visual analog scale score was observed between patient and proxy versions. Proxy's education level, patient's curvature type, and treatment modality were the significant determinants of the agreement in "Mobility," "usual activities," and "pain/discomfort" dimension, respectively. Conclusion Proxy-reported EQ-5D-3L-Y demonstrates good feasibility and satisfactory agreement with patient version. Proxy's education appears to have positive influence in agreement between patient-proxy dyads. Level of evidence 2.Study design Expert opinion-modified Delphi study. Objective We used a modified Delphi approach to obtain consensus among leading spinal deformity surgeons and their neuroanesthesiology teams regarding optimal practices for obtaining reliable motor evoked potential (MEP) signals. Summary of background data Intraoperative neurophysiological monitoring of transcranial MEPs provides the best method for assessing spinal cord integrity during complex spinal surgeries. MEPs are affected by pharmacological and physiological parameters. It is the responsibility of the spine surgeon and neuroanesthesia team to understand how they can best maintain high-quality MEP signals throughout surgery. Nevertheless, varying approaches to neuroanesthesia are seen in clinical practice. Methods We identified 19 international expert spinal deformity treatment teams. A modified Delphi process with two rounds of surveying was performed. Greater than 50% agreement on the final statements was consi
