Neurological complications in oncological and degenerative spine surgery represent one of the most feared risks of these procedures. Multimodal intraoperative neurophysiological monitoring (IONM) mainly uses methods to detect changes in the patient's neurological status in a timely manner, thus allowing actions that can reverse neurological deficits before they become irreversible. The utopian goal of spinal surgery is the absence of neurological complications while the realistic goal is to optimize the responses to changes in neuromonitoring such that permanent deficits occur less frequently as possible. In 2014, an algorithm was proposed in response to changes in neuromonitoring for deformity corrections in spinal surgery. There are several studies that confirm the positive impact that a checklist has on care. The proposed checklist has been specifically designed for interventions on stable columns which is significantly different from oncological and degenerative surgery. The goal of this project is to provide a checklist for oncological and degenerative spine surgery to improve the quality of care and minimize the risk of neurological deficit through the optimization of clinical decision-making during periods of intraoperative stress or uncertainty. After a literature review on risk factors and recommendations for responding to IONM changes, 3 surveys were administered to 8 surgeons with experience in oncological and degenerative spine surgery from 5 hospitals in Italy. In addition, anesthesiologists, intraoperative neuro-monitoring teams, operating room nurses participated. The members participated in the optimization and final drafting of the checklist. The authors reassessed and modified the checklist during 3 meetings over 9 months, including a clinical validation period using a modified Delphi process. A checklist containing 28 items to be considered in responding to the changes of the IONM was created. The checklist was submitted for inclusion in the new recommendations of the Italian Society of Clinical Neurophysiology (SINC) for intraoperative neurophysiological monitoring. The final checklist represents the consensus of a group of experienced spine surgeons. The checklist includes the most important and high-performance items to consider when responding to IONM changes in patients with an unstable spine. The implementation of this checklist has the potential to improve surgical outcomes and patient safety in the field of spinal surgery

There is an inherent risk of iatrogenic new neurological deficit (NND) arising at the spinal cord, cauda equina and nerve root during spinal surgery. Intraoperative neurophysiological monitoring (IONM) can be employed to preserve spinal cord function during spinal surgery. IONM techniques include somatosensory and motor evoked potentials, amongst others. A Canadian survey of 95 spinal surgeons showed that 62.1% used IONM and a similar survey in France of 117 spinal surgeons showed that only 36% used IONM. Unavailability was a common reason for its disuse. Current literature by the British Society of Clinical Neurophysiology has outlined the importance of IONM in preventing NND and the need for the implementation of guidelines for IONM. The lack of an established guideline has resulted in a varied approach in the use of IONM in England. There has been no previous attempt to ascertain the current use of IONM in England. Our study is aimed at assessing the variability of the use of IONM in England as well as identifying the rationale amongst surgeons that dictate their use of IONM. We are in the process of investigating the indications of use of IONM for cervical and lumbar spine procedures in 252 spinal surgeons from 33 hospitals with spinal services. Our survey will illustrate the current use of IONM in spinal surgery in England. It will highlight some of the reasons for the variability of use of IONM and identify factors that can contribute to a more standardised use of IONM in spinal surgery
