Patterns of Care and Persistence After Incident Elevated Blood Pressure

Abstract

WHAT'S KNOWN ON THIS SUBJECT: Screening for hypertension in asymptomatic children and adolescents occurs during routine care. For those with elevated blood pressure, a repeat measurement within 1 to 2 weeks is recommended. However, little is known about patterns of care after an incident elevated blood pressure. WHAT THIS STUDY ADDS:In a population of 72 625 children and adolescents, 6108 (8.4%) had an incident elevated blood pressure. Among these, 1275 (20.9%) had their blood pressure measurement repeated within 1 month. However, few individuals with an incident elevated blood pressure subsequently developed hypertension.abstract BACKGROUND AND OBJECTIVE: Screening for hypertension in children occurs during routine care. When blood pressure (BP) is elevated in the hypertensive range, a repeat measurement within 1 to 2 weeks is recommended. The objective was to assess patterns of care after an incident elevated BP, including timing of repeat BP measurement and likelihood of persistently elevated BP. METHODS:This retrospective study was conducted in 3 health care organizations. All children aged 3 through 17 years with an incident elevated BP at an outpatient visit during 2007 through 2010 were identified. Within this group, we assessed the proportion who had a repeat BP measured within 1 month of their incident elevated BP and the proportion who subsequently met the definition of hypertension. Multivariate analyses were used to identify factors associated with follow-up BP within 1 month of initial elevated BP.RESULTS: Among 72 625 children and adolescents in the population, 6108 (8.4%) had an incident elevated BP during the study period. Among 6108 with an incident elevated BP, 20.9% had a repeat BP measured within 1 month. In multivariate analyses, having a followup BP within 1 month was not significantly more likely among individuals with obesity or stage 2 systolic elevation. Among 6108 individuals with an incident elevated BP, 84 (1.4%) had a second and third consecutive elevated BP within 12 months. CONCLUSIONS:Whereas .8% of children and adolescents had an incident elevated BP, the great majority of BPs were not repeated within 1 month. However, relatively few individuals subsequently met the definition of hypertension. Pediatrics 2013;132:e349-e355 AUTHORS:
