ABSTRACT:
Hypertension (HTN) and elevated blood pressure (EBP) lead to appreciable morbidity in pediatric patients,
affecting them throughout life. Three to five percent of children have HTN, a rate that is steadily increasing.
Almost 40% of pediatric HTN patients have left ventricular hypertrophy at diagnosis, suggesting delays in
diagnosis and management initiation are affecting patients. Comprehensive, evidence-based guidelines for
HTN diagnosis and management were updated in August 2017, but it is uncertain how to best implement HTN
guidelines and reduce harm from failure to properly diagnose and manage HTN. Research by this investigative
team with a national group of 30 primary care practices significantly reduced the recognition of elevated BP
error rate, but strategies to move from recognition to diagnosis and management are unclear. Implementation
research on primary and subspecialty care integration around HTN can serve as a model for other pediatric
chronic conditions. Quality improvement collaboratives (QICs) often bring together either primary or
subspecialty care physicians, but few integrate both primary and subspecialty care physicians to create
comprehensive care improvement. It is unclear if pediatricians can effectively diagnose and manage chronic
conditions like HTN with subspecialist back-up only, and it is uncertain how to effectively integrate primary and
subspecialty care to reduce the harmful sequelae of pediatric HTN. This grant proposes to conduct a
multisite, prospective, cluster-randomized trial, broadening and deepening our prior work on
recognition of pediatric elevated BP, which will test methodologies to ensure every pediatric patient is
screened, and if HTN or EBP are present, diagnosed and managed appropriately and expeditiously.
This project will randomize at least 60 pediatric practices from across the country in a stepped-wedge fashion
to a HTN QIC a) without subspecialist involvement, b) with subspecialist involvement and c) with pediatrician
HTN diagnosis and management, and subspecialist back-up. It will also serve as a test case for whether
pediatricians can diagnose and manage common chronic conditions (e.g., HTN) with a supporting
subspecialist advisor. This proposal responds to AHRQ's Funding Opportunity Announcement PA-15-339,
designed to develop evidence to improve safety in ambulatory care settings and focuses on children in rural
and urban settings, AHRQ priority populations. This proposal, led by an experienced research team, will
identify a clear implementation strategy for rigorous, evidenced-based pediatric HTN diagnosis and
management, and highlight a model to increase primary and subspecialty care integration that can be
reproduced across other chronic conditions.
