The authors examined hospitalization rates of Kawasaki Syndrome (KS) among Texas children to isolate clusters, identify demographic disparities, and suggest possible causative factors. Using a retrospective cross-sectional study design, they studied 330 KS cases from 2,818,460 hospital discharges. The majority of the cases (61.5%) occurred within the 1-4-years-old category, representing the highest hospitalization rate (14.3 per 100,000 children). Almost 75% of the KS population was less than 5 years old, with hospitalization rates approximately 8 times higher than that of all other children (p < .05). KS diagnosis occurred for only 49.4% of all KS cases upon admission. Along with high-density clusters identified in major metropolitan areas, the authors found the highest rates of KS among Asian and Pacific Islander and non-Hispanic black children. Genetic predispositions and access to healthcare issues may explain the results. The authors recommend improving educational initiatives with healthcare providers and establishing KS as a reportable condition.
