Allogeneic Red Blood Cell Transfusion and Infectious Complications Following Pediatric Spinal Fusion: NSQIP-P Analysis.
JB & JS Open Access 2022 October
Substantial bleeding occurs during spinal fusion surgery in the pediatric population, and many patients receive allogeneic red blood cell transfusion (ARBT) for the treatment of resulting perioperative anemia. ARBT is thought to increase vulnerability to postoperative infections following major surgical procedures, but studies of this relationship in children undergoing spinal fusion have yielded conflicting results.
Methods: Patients who underwent spinal fusion before the age of 18 years were identified from the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) 2016 to 2019 databases, along with patient and procedure-specific characteristics, transfusion events and volumes, and postoperative infectious complications such as wound-related infection, pneumonia, urinary tract infection (UTI), and sepsis. Multivariable logistic regression analyses provided adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for the association between ARBT and each infection outcome and the overall risk of infection.
Results: Among 19,159 patients studied, 714 (3.7%) developed a total of 931 episodes of postoperative infection. In multivariable logistic regression analyses, perioperative ARBT was independently associated with postoperative pneumonia (aOR = 1.93, 95% CI = 1.40 to 2.68), UTI (aOR = 1.80, 95% CI = 1.19 to 2.73), sepsis (aOR = 1.58, 95% CI = 1.10 to 2.28), and the overall risk of infection (aOR = 1.40, 95% CI = 1.20 to 1.64). The risk of any postoperative infection increased in a dose-response fashion with transfusion volume.
Conclusions: ARBT in pediatric spinal fusion is associated with significantly increased risks of postoperative pneumonia, UTI, and sepsis. The overall risk of postoperative infection increases with the volume transfused. Enhanced efforts to minimize perioperative anemia and ARBT should be considered as a means of improving patient outcomes.
Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
