Variations in Sedated Echocardiography and Association With Repeat Echocardiography in Nonrefractory Kawasaki Disease.

Echocardiography performed under sedation allows for better coronary artery visualization in children with Kawasaki disease. We sought to describe hospital-level variability in the percentage of sedated echocardiography (SE) among children with nonrefractory Kawasaki disease (NRKD) and then test its association with repeat echocardiography, length of stay (LOS), and costs. We identified children in the Pediatric Health Information System <36 months of age hospitalized with NRKD from March 2010 to February 2017. Hospital-level percentage of SE was the primary outcome. Secondary outcomes were repeat echocardiography during the same hospitalization, LOS, and costs. We used χ There were 2887 NRKD hospitalizations from 40 children's hospitals. Initial SE varied from 0.0% to 87.0% (median 5.9%; interquartile range 1.4%-21.1%). Of initial echocardiographies, 22.4% were sedated and 10.1% of all hospitalizations had a repeat echocardiography. Use of SE at the hospital level was associated with a lower likelihood for repeat echocardiography ( Significant variation exists in the use of SE for children <36 months of age with NRKD at children's hospitals. Our results suggest that determination of SE should not be driven by concern for repeat echocardiography or LOS considerations.
