Factors Associated With Resource Utilization and Coronary Artery Dilation in Refractory Kawasaki Disease (from the Pediatric Health Information System Database).
Management guidelines for refractory Kawasaki disease (KD) are vague. We sought to assess practice variation and identify factors associated with large/complex coronary artery aneurysms (LCAA) and resource utilization in refractory KD. This retrospective cohort study identified patients aged ≤18 years with KD (2004 to 2014) using the Pediatric Health Information System. ⋯ In conclusion, treatment for refractory KD varies widely. Concomitant viral infection was associated with a greater risk of LCAA in refractory KD. Better understanding of optimal management may improve outcomes and decrease both variability in management and resource utilization for refractory KD.
