Insights
Different care models for Kawasaki disease (KD) show varied utilization and costs, but no significant differences in cardiac outcomes like coronary artery aneurysms (CAAs). Further research is needed to optimize KD care value.
Area of Science:
- Pediatric Cardiology
- Health Services Research
Background:
- Kawasaki disease (KD) requires careful management to prevent cardiac complications.
- Different hospital care models exist for managing pediatric KD, but their comparative effectiveness is not well understood.
Purpose of the Study:
- To describe the prevalence of various care models for children with KD.
- To evaluate healthcare utilization and cardiac outcomes associated with different KD care models.
Main Methods:
- A multicenter, retrospective cohort study of 2080 children hospitalized with KD in US children's hospitals (2017-2018).
- Hospitals were classified into three care models: hospitalist with as-needed consultation (Model 1), hospitalist with automatic consultation (Model 2), and subspecialist primary service (Model 3).
- Utilization outcomes and coronary artery aneurysm (CAA) frequency were analyzed using administrative data and chart reviews.
Main Results:
- Model 1 hospitals used more laboratory tests and had lower costs. Model 3 hospitals more frequently used echocardiograms and immune modulators.
- No significant differences were observed among the care models in length of stay, readmission rates, emergency department revisits, or the frequency of CAAs.
Conclusions:
- While distinct KD care models exhibit variations in resource utilization and costs, they do not appear to significantly impact cardiac outcomes.
- Further investigation into KD primary service and consultation practices is warranted to enhance healthcare value and patient outcomes.
Objectives:
Describe the prevalence of different care models for children with Kawasaki disease (KD) and evaluate utilization and cardiac outcomes by care model.
Methods:
Multicenter, retrospective cohort study of children aged 0 to 18 hospitalized with KD in US children's hospitals from 2017 to 2018. We classified hospital model of care via survey: hospitalist primary service with as-needed consultation (Model 1), hospitalist primary service with automatic consultation (Model 2), or subspecialist primary service (Model 3). Additional data sources included administrative data from the Pediatric Health Information System database supplemented by a 6-site chart review. Utilization outcomes included laboratory, medication and imaging usage, length of stay, and readmission rates. We measured the frequency of coronary artery aneurysms (CAAs) in the full cohort and new CAAs within 12 weeks in the 6-site chart review subset.
Results:
We included 2080 children from 44 children's hospitals; 21 hospitals (48%) identified as Model 1, 19 (43%) as Model 2, and 4 (9%) as Model 3. Model 1 institutions obtained more laboratory tests and had lower overall costs (P < .001), whereas echocardiogram (P < .001) and immune modulator use (P < .001) were more frequent in Model 3. Secondary outcomes, including length of stay, readmission rates, emergency department revisits, CAA frequency, receipt of anticoagulation, and postdischarge CAA development, did not differ among models.
Conclusions:
Modest cost and utilization differences exist among different models of care for KD without significant differences in outcomes. Further research is needed to investigate primary service and consultation practices for KD to optimize health care value and outcomes.
