To compare pediatric hypertensive patients identified through clinical and claims-based definitions, analyzing demographics, baseline profiles, and follow-up time profiles.
Key Findings:
9% of children and 8.7% of teens met the clinical definition for hypertension.
2.8% of children and 11% of teens had elevated, nonhypertensive blood pressure.
Only 2.2% of clinically hypertensive children and 7.3% of teens had corresponding claims for hypertension.
Claims-based patients exhibited greater disease severity and higher all-cause mortality rates during follow-up.
Interpretation:
Pediatric hypertension is under-captured in claims-based data, which may indicate more severe disease in those identified through claims. Understanding coding practices is crucial for accurate research.
Limitations:
Claims data may not fully represent the pediatric hypertensive population.
Potential biases in cohort selection and follow-up duration.
Conclusion:
The study highlights the importance of using clinical definitions for identifying pediatric hypertension and suggests that claims data may not adequately capture this population.
