Flowchart and checklist for transcranial motor evoked potential alarm for reducing true-positive and false-positive cases: a prospective multicenter study.

Applying a flowchart and checklist improved intraoperative responses to Tc-MEP alarms by facilitating early identification of surgery- and nonsurgery-related factors and guiding appropriate interventions. Using these tools led to a significant reduction in TP and FP cases and increased rescue cases, ultimately enhancing the safety and reliability of spine surgeries.
