Mortality and associated factors of JIA in hospitalized Thai children: a nationwide data analysis 2015–2023
Authors' conclusion
Although overall mortality and intubation rates were low, respiratory failure identified a small, high-risk subgroup with substantial mortality and healthcare burden.
Study context
- Population
- Hospital admissions of patients younger than 18 years with JIA, Thailand's National database, January 2015 to December 2023
- Participants
- 3,754 JIA admissions
- Outcome
- In-hospital mortality and respiratory failure (defined by endotracheal intubation)
Methodological detailsnationwide administrative inpatient database, multivariable logistic regression
- Nationwide administrative inpatient database
- Multivariable logistic regression
