Abstract

Background:

Kawasaki disease is an acute vasculitis of childhood and is the leading cause of acquired heart disease in the developed countries.

Methods:

Data from hospital discharge records were obtained from the National Kids Inpatient Database for years 2009 and 2012. Hospitalisations by months, hospital regions, timing of admission, insurance types, and ethnicity were analysed. Length of stay and total charges were also analysed.

Results:

There were 10,486 cases of Kawasaki disease from 12,678,005 children hospitalisation. Kawasaki disease was more common between 0 and 5 years old, in male, and in Asian. The January–March quarter had the highest rate compared to the lowest in the July–September quarter (OR=1.62, p < 0.001). Admissions on the weekend had longer length of stay [4.1 days (95 % CI: 3.97–4.31)] as compared to admissions on a weekday [3.72 days (95 % CI: 3.64–3.80), p < 0.001]. Blacks had the longest length of stay and whites had the shortest [4.33 days (95 % CI: 4.12–4.54 days) versus 3.60 days (95 % CI: 3.48–3.72 days), p < 0.001]. Coronary artery aneurysm was identified in 2.7 % of all patients with Kawasaki disease. Children with coronary artery aneurysm were hospitalised longer and had higher hospital charge. Age, admission during weekend, and the presence of coronary artery aneurysm had significant effect on the length of stay.

Conclusions:

This report provides the most updated epidemiological information on Kawasaki disease hospitalisation. Age, admissions during weekend, and the presence of coronary artery aneurysm are significant contributors to the length of stay.
