Abstract

Background: Kawasaki disease is the leading cause of acquired heart disease in children in the US. While it remains a rare disease, the purpose of this study is to evaluate the incidence of KD

Methods: To evaluate our hypothesis we used the Pediatric Health Information Systems (PHIS), 2004-2013, including all discharges at 44 of the largest freestanding children’s hospitals in the US.

Results: Between 2004-2013, there were 16,417 hospitalizations for KD, 10,388 (61%) were male. The race of patients admitted with KD showed 5276 (31%) Caucasian, 2370 (14%) African American, 1586 (9.3%) Other, and 941 (5.5%) Asian. The average length of stay 3.9 days. The number of patients with KD increased annually for the past decade, Figure 1.

The largest proportion of the increase was from those children between 1 and 5 years of age, Figure 2.

Most children were only hospitalized once (14,231, 84%) however some children required subsequent hospitalization (1,291,8%).

Conclusions: There has been a steady increase in the number of admissions per year for Kawasaki disease predominately for those patients ages 1-5 years.
