Paediatric ballistic fracture patients: who has poor follow-up and why?

Purpose: Firearm-related injuries in children and adolescents have increased over the past decade. The standard of care for ballistic fractures in children is complex, resulting in a burden of healthcare follow-up that many families find challenging. Consistent follow-up is crucial, especially in orthopaedic trauma and firearm cases, to prevent complications. This study aims to identify demographic and clinical variables associated with loss to follow-up (LTFU) in paediatric patients with ballistic fractures. Methods: This is a retrospective registry study at a Level I trauma centre for patients aged zero to 21 who presented with a ballistic-induced fracture. Patients with isolated skull, facial, or rib fractures were excluded. Follow-up was dichotomized at the median number of follow-up days for analysis. Logistic regression analysis was used to identify predictors of LTFU. Results: The study included 144 patients with a median age of 18 years. The majority were male (89%) and White (72%). Most patients had government insurance (44%) or were uninsured (33%). The mechanism of injury was primarily assault (71%). Operative intervention occurred in 55% of cases. Key factors increasing follow-up adherence included male sex (p = 0.011), higher injury severity scores (p = 0.009), requiring operative intervention (p < 0.001), air transportation (p < 0.001), or injury at a private residence (p = 0.040). Uninsured status (p = 0.007), opioid use (p = 0.047), and greater distance from the hospital (p = 0.002) were associated with low follow-up. Conclusions: This study identifies key factors influencing follow-up adherence in pediatric patients with ballistic fractures. Identifying these factors allows for tailoring future interventions to improve follow-up adherence for this vulnerable population.
