Childhood vasculitis hospitalizations in Spain, 1997-2011

Area of Science:

• Pediatric Rheumatology
• Epidemiology
• Public Health

Background:

• Childhood vasculitis represents a significant health concern.
• Understanding the hospital burden is crucial for resource allocation and care improvement.

Purpose of the Study:

• To analyze the hospital burden of childhood vasculitis in Spain from 1997 to 2011.
• To determine disease prevalence, hospitalization rates, and trends.
• To identify common types and associated costs.

Main Methods:

• Utilized the National Discharges Basic Minimum Data Set for inpatient pediatric events (age < 15).
• Classified vasculitis diagnoses using the Ninth Revision of the International Classification of Diseases.
• Analyzed data for Takayasu arteritis, Polyarteritis nodosa, Kawasaki disease, Wegener's granulomatosis, Churg-Strauss syndrome, and Henoch-Schönlein purpura.

Main Results:

• 14,518 childhood vasculitis hospitalizations were recorded.
• The average hospitalization rate was 13.33 per 100,000 children.
• Henoch-Schönlein purpura (11.00/100,000) and Kawasaki disease (3.97/100,000) were most prevalent.
• Average length of stay was 6.04 days, with an estimated cost of €2,847 per admission.
• Overall case fatality rate was 0.05%.

Conclusions:

• Henoch-Schönlein purpura and Kawasaki disease dominate the pediatric vasculitis hospital landscape in Spain.
• Epidemiological insights are vital for informed healthcare policy and research direction in pediatric rheumatology.
• The study highlights the need for continued monitoring and targeted interventions for childhood vasculitis.
