Study Design Retrospective clinical study of a prospectively collected, national database. Objective Determine the 30-day incidence, timing, and risk factors for venous thromboembolism (VTE) following thoracolumbar spine surgery. Methods The American College of Surgeons National Surgical Quality Improvement Program Participant Use File identified 43,777 patients who underwent thoracolumbar surgery from 2005 to 2012. Multiple patient characteristics were identified. The incidence and timing (in days) of deep vein thrombosis (DVT) and pulmonary embolus (PE) were determined. Multivariable regression analysis was performed to identify significant risk factors. Results Of the 43,777 patients identified as having had thoracolumbar surgery, 202 cases of PE (0.5%) and 311 cases of DVT (0.7%) were identified. VTE rates were highest in patients undergoing corpectomy, with a 1.7% PE rate and a 3.8% DVT rate. Independent risk factors for VTE included length of stay (LOS) ≥ 6 days (odds ratio [OR] 4.07), disseminated cancer (OR 1.77), white blood cell count > 12 (OR 1.76), paraplegia (OR 1.75), albumin < 3 (OR 1.73), American Society of Anesthesiologists class 4 or greater (OR 1.54), body mass index > 40 (OR 1.49), and operative time > 193 minutes (OR 1.43). LOS < 3 days was protective (OR 0.427). Conclusions We report an overall 30-day PE rate of 0.5% and DVT rate of 0.7% following thoracolumbar spine surgery. Patients undergoing corpectomy were at highest risk for VTE. Multiple VTE risk factors were identified. Further studies are needed to develop algorithms to stratify VTE risk and direct prophylaxis accordingly.

OBJECTIVE Existing studies have shown a high overall rate of adverse events (AEs) following pediatric neurosurgical procedures. However, little is known regarding the morbidity of specific procedures or the association with risk factors to help guide quality improvement (QI) initiatives. The goal of this study was to describe the 30-day mortality and AE rates for pediatric neurosurgical procedures by using the American College of Surgeons (ACS) National Surgical Quality Improvement Program–Pediatrics (NSQIP-Peds) database platform. METHODS Data on 9996 pediatric neurosurgical patients were acquired from the 2012–2014 NSQIP-Peds participant user file. Neurosurgical cases were analyzed by the NSQIP-Peds targeted procedure categories, including craniotomy/craniectomy, defect repair, laminectomy, shunts, and implants. The primary outcome measure was 30-day mortality, with secondary outcomes including individual AEs, composite morbidity (all AEs excluding mortality and unplanned reoperation), surgical-site infection, and unplanned reoperation. Univariate analysis was performed between individual AEs and patient characteristics using Fischer's exact test. Associations between individual AEs and continuous variables (duration from admission to operation, work relative value unit, and operation time) were examined using the Student t-test. Patient characteristics and continuous variables associated with any AE by univariate analysis were used to develop category-specific multivariable models through backward stepwise logistic regression. RESULTS The authors analyzed 3383 craniotomy/craniectomy, 242 defect repair, 1811 laminectomy, and 4560 shunt and implant cases and found a composite overall morbidity of 30.2%, 38.8%, 10.2%, and 10.7%, respectively. Unplanned reoperation rates were highest for defect repair (29.8%). The mortality rate ranged from 0.1% to 1.2%. Preoperative ventilator dependence was a significant predictor of any AE for all procedure groups, whereas admission from outside hospital transfer was a significant predictor of any AE for all procedure groups except craniotomy/craniectomy. CONCLUSIONS This analysis of NSQIP-Peds, a large risk-adjusted national data set, confirms low perioperative mortality but high morbidity for pediatric neurosurgical procedures. These data provide a baseline understanding of current expected clinical outcomes for pediatric neurosurgical procedures, identify the need for collecting neurosurgery-specific risk factors and complications, and should support targeted QI programs and clinical management interventions to improve care of children.

Abstract BACKGROUND: Cerebrovascular surgery offers potentially lifesaving treatments for intracranial vascular pathology yet bears substantial risks in the form of perioperative complications and mortality. OBJECTIVE: To better characterize the risks associated with cerebrovascular surgery by broadly investigating the incidence of complications, patient-level predictors of complications, and mortality using the National Surgical Quality Improvement Program database, a prospective, audited, national data set. METHODS: All cerebrovascular cases were extracted from the National Surgical Quality Improvement Program with the use of Current Procedural Terminology codes. Complication and mortality rates were analyzed with univariate and multivariate statistical analyses. RESULTS: A total of 1141 cases were analyzed. The rate of complications was nearly twice that of previous estimates: Almost one-third of patients (30.9%) experienced at least 1 complication, which was significantly associated with 30-day mortality (odds ratio, 7.76; 95% confidence interval, 4.27-14.10; P &lt;.001). Emergency surgery was associated with higher mortality rates (15.1%) than nonemergency procedures (2.3%). Significant predictors of complications included preoperative ventilator dependence, emergency surgery, bleeding disorders, diabetes mellitus, and alcohol abuse. Significant predictors of mortality included postoperative coma &gt;24 hours, preoperative or postoperative ventilator dependence, black or Asian race, and stroke. The most common complications were ventilator dependence (64.5% in patients ventilated preoperatively, 8.4% in patients not ventilated preoperatively), bleeding requiring transfusion (10.2%), reoperation within 30 days (9.6%), pneumonia (7.3%), and stroke (7.3%). CONCLUSION: Cerebrovascular surgery is associated with significant risks of morbidity and mortality. Mitigation of these risks requires broader, patient-centered understanding of risk factors and complications specific to cerebrovascular surgery, as presented in this article. These findings pave the way for improving patient safety and outcomes in cerebrovascular surgery.
