Updating the Evidence: Systematic Literature Review of Risk Factors and Strategies for Prevention, Diagnosis, and Treatment of Surgical Site Infection After Pediatric Scoliosis Surgery.

Abstract

Surgical site infection (SSI) is a major potential complication following pediatric spinal deformity surgery that is associated with significant morbidity and increased costs. Despite this, SSI rates remain high and variable across institutions, in part due to a lack of up-to-date, comprehensive prevention, and treatment protocols. Furthermore, few attempts have been made to review the optimal diagnostic modalities and treatment strategies for SSI following scoliosis surgery. The aim of this study was to systematically review current literature on risk factors for SSI in pediatric patients undergoing scoliosis surgery, as well as strategies for prevention, diagnosis, and treatment. On January 19, 2022, a systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies reporting risk factors for acute, deep SSI (<90d) or strategies for prevention, diagnosis, or treatment of SSI following pediatric scoliosis surgery were included. Each included article was assigned a level of evidence rating based on study design and quality. Extracted findings were organized into risk factors, preventive strategies, diagnostic modalities, and treatment options and each piece of evidence was graded based on quality, quantity, and consistency of underlying data. A total of 77 studies met the inclusion criteria and were included in this systematic review, of which 2 were categorized as Level I, 3 as Level II, 64 as Level III, and 8 as Level IV. From these studies, a total of 29 pieces of evidence (grade C or higher) regarding SSI risk factors, prevention, diagnosis, or treatment were synthesized. We present an updated review of published evidence for defining high-risk patients and preventing, diagnosing, and treating SSI after pediatric scoliosis surgery. The collated evidence presented herein may help limit variability in practice and decrease the incidence of SSI in pediatric spine surgery. Level III-systematic review.
