Variability in Early Surgery for Acute Cervical Spinal Cord Injury Patients: An Opportunity for Enhanced Care Delivery.

Abstract

Data supporting the benefits of early surgical intervention in acute spinal cord injury (SCI) is growing. For early surgery to be accomplished, understanding the causes of variabilities that effect the timing of surgery is needed to achieve this goal. The purpose of this analysis is to determine factors that affect the timing of surgery for acute cervical SCI within the North American Clinical Trials Network (NACTN) for SCI registry. Patients in the NACTN SCI registry from 2005 to 2019 with a cervical SCI, excluding Acute Traumatic Central Cord Syndrome, were analyzed for time elapsed from injury to arrival to the hospital, and time to surgery. Two categories were defined: 1) Early Arrival with Early Surgery commenced within 24 hours of injury (EAES) and 2) Early Arrival but Delayed Surgery (EADS) with surgery occurring between 24 to 72 hours post-injury. Patients' demographic features, initial clinical evaluation, medical comorbidities, neurological status, surgical intervention, complications, and outcome data were correlated with respect to the two arrival groups. Of the 222 acute cervical SCI patients undergoing surgery, 163 (73.4%) were EAES, and 59 (26.6%) were EADS. There was no statistical difference in arrival time between the EAES and EADS groups. There was a statistical difference in the median arrival time to surgery between the EAES group (9 hours) compared to the EADS group (31 hours) (p<0.05). There was no statistical difference in race, sex, age, mechanism of injury, APACHE II scores, or medical comorbidities between the two groups but the EAES group did present with a significantly lower systolic blood pressure (p<0.05). EADS patients were more likely to present as an AIS D than EAES (p<0.05). Early surgery was statistically more likely to occur if the injury occurred over the weekend (p<0.05). There were variations in the rates of early surgery between the 8 NACTN sites within the study, ranging from 57% to 100%. Of the 114 patients with 6-month outcome data, there was no significant change between the two groups regarding AIS grade change and motor/pin prick/light touch score recovery. A trend towards improved motor scores with early surgery was not statistically significant (p=0.21). Although there is data that surgery within 24 hours of injury improves outcomes and can be performed safely, there remain variations in care outside of clinical trials. In the present study of cervical SCI, NACTN achieved its goal of early surgery in 73.4% of patients from 2005-2019 who arrived within 24 hours of their injury. Variability in achieving this goal was related to severity of neurological injury, the day of the week, and the treating NACTN center. Evaluating variations within our network improves understanding of potential systemic limitations and our decision-making process to accomplish the goal of early surgery.

Professor of Neurosurgery

As a Neurosurgeon with fellowship training in Spine Surgery, I have dedicated my professional life to treating patients with spine disorders. These include spinal stenosis, spondylolisthesis, scoliosis, herniated discs and spine tumors. I incorporate minimally-invasive spine (MIS) techniques whenever appropriate to minimize pain and length of stay, yet not compromise on achieving the goals of surgery, which is ultimately to get you back to the quality of life you once enjoyed. I was drawn to medicine and neurosurgery for the unique ability to incorporate the latest in technology and neuroscience to making patients better. I will treat you and your loved ones with the same kind of care I would want my loved ones to be treated with. In addition to my clinical practice, I will be working with Duke Bioengineers and Neurobiologists on important basic and translational questions surrounding spinal cord injuries (SCI), which we hope to bring to clinical relevance.
