    ObjectiveHigher benchmarks in safety for patients undergoing neurosurgery have been introduced. With these principles, new tools and techniques were established, including intraoperative neurophysiological monitoring (IONM). Current trends as a function of patient-, surgeon-, and procedure-related factors and complication rates in the utilization of IONM as an adjunct to the practice of pediatric neurosurgery have not been investigated previously.MethodsBetween 2008 and 2011, 4467 neurosurgical procedures were performed on 2352 patients at Texas Children's Hospital. A retrospective chart review was performed in which surgeon, procedure, and patient characteristics, as well as perioperative complications, were recorded for IONM and non-IONM cases.ResultsNeurosurgical procedures performed with IONM steadily increased. Surgeon-related factors associated with IONM use included surgeons with <10 years of practice (P < .0001), and subspecialty interest in spine (P < .0001) and oncology (P = .0048). Procedure-related factors associated with IONM use included operations involving the spinal cord (P < .0001). Patient-related factors associated with IONM use included children older than 3 years of age and with increased American Society of Anesthesiologists score (P < .0001). The neurological complication rate in the IONM cohort (range 3.4% to 11.3%; mean 6.4%) was significantly higher compared to the non-IONM cohort (range 1.1% to 1.8%; mean 1.5%) (P < .0001).ConclusionsThe percent of procedures performed with IONM increased. However, these trends do not seem governed by improvement to patient outcomes because the complication rates were higher in the IONM cohort than the non-IONM cohort.Copyright © 2014 Elsevier Inc.
