Perioperative Complications and Mortality Following Anterior Odontoid Screw Fixation in Elderly Patients: A National Database Analysis.

Abstract:

OBJECTIVE:To identify predictors of short-term mortality and complications after anterior odontoid screw fixation. METHODS:This was a retrospective analysis of a national database. The American College of Surgeons National Quality Improvement Database was queried using Current Procedural Terminology codes to identify patients aged ≥60 years who underwent surgery for anterior fixation of odontoid fracture admitted from 2007 to 2016. Univariate analysis and subsequent multivariate analysis were used to analyze risk factors for postoperative complications and 30-day postoperative mortality. Complications were defined as surgical-site infection, wound breakdown, pneumonia, venous thromboembolism, stroke, myocardial infarction, sepsis, renal progressive renal insufficiency/acute kidney injury, or cardiac arrest. RESULTS:A total of 198 patients were identified. Mean age was 77.7 (±8.7) years and 60.6% were female. Overall mortality rate was 7.6%, and the complication rate was 9.1%. In multivariate analysis, dependent functional status (0.012; odds ratio [OR] 5.2; 95% confidence interval [CI] 1.42-18.72) and preoperative systemic inflammatory response syndrome (P = 0.011; OR 6.2; 95% CI 1.52-25.79) predicted mortality. Emergency case status (P = 0.033; OR 3.4; 95% CI 1.10-10.70) predicted perioperative complications. Age was not significantly associated with either complications or mortality in multivariate analysis. CONCLUSIONS:Functional dependence and preoperative systemic inflammatory response syndrome predict mortality following odontoid screw placement. Although age often is considered a limiting factor in pursuing surgical intervention in patients with odontoid fracture, age did not independently increase odds of either complications or perioperative mortality in this analysis. Further studies are needed to explore these findings.
