ABSTRACT
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. Refractory KD was defined as receiving >1 dose of intravenous immunoglobulin. Demographics, medications, concomitant infections, length of stay (LOS), and charges were collected. Antithrombotic therapy was a surrogate for LCAA. LOS and hospital charges assessed resource utilization. Multivariate regression identified factors associated with LOS, charges, and LCAA. Of 14,194 patients with KD, 2,974 (21%) had refractory KD and 203 of those 2,974 (7%) had LCAA. Additional intravenous immunoglobulin was the sole medication in 77%. Other medications added were steroids (18%), infliximab (2%), and both (3%). Warfarin, low-molecular-weight heparin, tissue plasminogen activator, and clopidogrel were prescribed with equal frequency (2%). Male gender (adjusted relative risk 1.52, 95% confidence interval [CI] 1.08 to 2.16, p <0.01), admission to an intensive care unit (4.79, 95% CI 3.40 to 6.74, p <0.001), arrhythmia (3.00, 95% CI 1.94 to 4.65, p <0.001), and concomitant viral infection (2.29, 95% CI 1.49 to 3.52, p <0.001) were associated with LCAA. Severe illness, race, region, and payer were independently associated with increased charges (p <0.05 for all). 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.
