Abstract
Purpose
The aim of this study was to characterize antibiotic prophylaxis practices in pediatric patients who have received posterior arthrodesis for spinal deformity and understand how these practices impact 30-day postoperative infection rates.
Methods
This was a retrospective cohort study using the National Surgical Quality Improvement Program Pediatric database for year 2021. Patients 18 years of age or younger who received posterior arthrodesis for scoliosis or kyphosis correction were included. The outcome of interest was 30-day postoperative infection. Fisher’s exact test and multivariable regression analysis were used to analyze the impact of intravenous antibiotic prophylaxis, intraoperative intravenous antibiotic redosing after 4 h, postoperative antibiotic prophylaxis, intraoperative topical antibiotics on 30-day postoperative infection, and various antibiotic prophylaxis regimens.
Results
A total of 6974 patients were included in this study. The 30-day infection rate was 2.9%. Presurgical intravenous antibiotic (11.5% vs. 2.7%, p = 0.005), postoperative antibiotic (5.7% vs. 2.4%, p < 0.01), and intraoperative topical antibiotic (4.0% vs. 2.7%, p = 0.019) were associated with significantly reduced infection rates. There was no significant difference in infection rates between patients that received cefazolin versus vancomycin versus clindamycin. The addition of Gram-negative coverage did not result in significant differences in infection rates. Multivariable regression analysis found postoperative intravenous antibiotics and intraoperative topical antibiotics to reduce infection rates.
Conclusions
We found the use of presurgical intravenous antibiotics, postoperative intravenous antibiotics, and intraoperative topical antibiotics to significantly reduce infection rates. Results from this study can be applied to future research on implementation of standardized infection prevention protocols.
