Objectives/Hypothesis: Quality improvement (QI) initiatives emphasize a need for reduction in hospital length of stay (LOS). We sought to determine the impact of surgical site infections (SSIs) on LOS after complex head and neck surgery (HNS). Study Design: Retrospective cohort analysis. Methods: An analysis of the American College of Surgeons National Surgical Quality Improvement Program was undertaken. All adult patients undergoing complex HNS from 2005 to 2016 were included in the analysis. Our main outcomes were SSI incidence and increase in hospital LOS attributable to SSI. Results: Of 4,014 patients identified, 16.5% developed SSI. History of smoking, diabetes, preoperative wound infection, contaminated or dirty wound classes, and prolonged operative time were found to significantly predict postoperative SSI. Adjusting for significant pre- and postoperative factors, SSI was associated with significantly increased LOS (hazard ratio = 0.486, 95% confidence interval: 0.419-0.522). Conclusions: SSI following complex HNS is associated with significantly increased hospital LOS. This result supports the need for institutional QI strategies that target SSIs after head and neck procedures in an effort to provide the highest quality care at the lowest possible cost. Our analysis identifies risk factors that can allow identification of patients at high risk of SSI and prolonged hospitalization. Level of Evidence: 2b Laryngoscope, 2020.
