Kawasaki Disease

Pathway Background and Objective(s)

Kawasaki Disease is one of the most common vasculitides of childhood, and is the most common cause of acquired heart disease in children in developed countries. There is an estimated annual incidence of 20 per 100,000 children younger than five years in the United States, and prevalence is higher in Japan and in children of Japanese or East Asian descent. While it is typically a self-limited condition, complications such as coronary artery aneurysms, myocardial dysfunction, and heart failure may develop and lead to significant morbidity and mortality. The underlying etiology is unknown, and given the high risk of delayed diagnosis and/or treatment, it is imperative to standardize care to expedite recognition and timely treatment of Kawasaki Disease.

The objectives of this pathway are to:

  • Standardize care of patients with Kawasaki Disease and Incomplete Kawasaki Disease
  • Reduce the incidence of coronary artery aneurysms
  • Reduce the time to IVIG treatment
  • Reduce inpatient length of stay
  • If steroids are used, reduce the incidence of refractory Kawasaki Disease
