Electronic Health Record-Based Clinical Decision Support to Improve Blood Pressure Management in Adolescents

The goal of this project is to improve detection and management of elevated blood pressure in adolescents. It (a) uses electronic health record (EHR) technology to deliver patient-specific clinical decision support (CDS) to providers at the point of care, (b) assesses the impact of this intervention on identification and clinical care of hypertension in adolescents, and (c) assesses the impact of the intervention on costs of care.

Study Overview

• Status: Completed
• Conditions: Hypertension; Obesity; Pre Hypertension
• Intervention / Treatment: Behavioral: Clinical Decision Support (CDS)

Detailed Description

Hypertension (HT) during adolescence tracks into adulthood, contributing to adult cardiovascular morbidity and mortality. National guidelines for the diagnosis and treatment of hypertension in children and adolescents were developed by the National High Blood Pressure Education Program (NHBPEP); their Fourth Report was published in 2004. Despite heightened awareness of hypertension in pediatric populations, most adolescents with elevated blood pressure remain clinically unrecognized. Factors that contribute to this gap in care include: the need to translate adolescent blood pressure (BP) measures into blood pressure percentiles on the basis of age, gender, and height, lack of familiarity with National High Blood Pressure Education Program (NHBPEP) clinical guidelines, and competing demands at clinical encounters.

Electronic health record (EHR)-based clinical decision support (CDS) can be used to address these barriers and support better care of elevated blood pressure (BP) and Hypertension (HT) in adolescents. In this project, the investigators integrate EHR-extracted data with sophisticated Web-based CDS algorithms to provide patient-specific point-of-care clinical recommendations, in accordance with NHBPEP guidelines. To evaluate the impact of this innovation on quality and cost of care, the investigators randomize 18 clinics with their 130 pediatric care providers (PCP) and their estimated 17,000 adolescent patients to receive or not receive this EHR-based CDS intervention. The investigators hypothesize that the intervention will improve recognition and early management of elevated BP and that short-term increases in outpatient care costs will be offset by longer-term clinical benefits, estimated using established econometric models.

This innovative project (a) addresses the under-recognized high-risk patient population of adolescents, (b) integrates EHR and Web-based CDS technology to provide sophisticated patient-specific point-of-care CDS, (c) develops and implements novel and intuitive visual interfaces to communicate CDS recommendations to PCPs, and (d) provides both clinical and cost outcome data useful to clinicians and policymakers. If the EHR-based CDS intervention improves adherence to NHBPEP recommendations, it will provide a much-needed tool to combat the burgeoning problem of rising cardiovascular risk factors in children and adolescents. Further, regardless of outcome, the technology that is developed and tested will provide many useful insights to advance the science of EHR-based CDS. This will, in turn, help translate the massive public and private investments in EHR technology into improved adolescent health outcomes.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Clinical Decision Support (CDS); The Clinical Decision Support (CDS) tool will be activated when a BP is entered in the vital sign section of the EHR during any visit to a family practice or pediatric clinic (including both preventive care and sick visits, excluding prenatal and postpartum visits). The algorithm will be embedded in the EHR. In most cases, when a normal BP <90% and <120/80 mm Hg is entered, no alerts will be triggered. In some cases, clinical staff may receive up to two alerts, either to measure height or to repeat a first elevated BP reading. In cases with confirmed elevated BP measures, providers will receive a single CDS message summarizing that patient's current BP status and recommending specific clinical actions.	Behavioral: Clinical Decision Support (CDS); The Clinical Decision Support (CDS) tool will be activated when a BP is entered in the vital sign section of the EHR. The CDS tool includes six key features: (i) prompts regarding the need for height data to classify the BP by percentile (ii) prompts to repeat any BP that is ≥90% or ≥120/80 mm Hg (iii) classification of BPs by percentile, including classification of those in pre-HT, stage 1 HT and stage 2 HT range (iv) review of previous HT diagnoses and BPs in order to classify elevated BPs as incident (first or second elevated BP) or persistent (third or greater elevated BP) (v) tailored CDS based on HT category and previous diagnoses (vi) graphical representation of current and historical BP data by age and BP percentile.
No Intervention: Control; Patients in this group will receive usual care from their clinic. The CDS tool will not be activated.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Participants With Clinical Recognition of Hypertension	Clinical recognition of hypertension as determined by one or more of the following; 1) hypertension or elevated BP as discharge diagnosis, 2) hypertension or elevated BP in the clinical note, 3) hypertension or elevated BP in discharge instructions, 4) hypertension or elevated BP added to the problem list.	6 months
Participants With Appropriate Workup for Secondary Causes of Hypertension	Appropriate workup for those with incident hypertension included an initiated workup for secondary causes of hypertension or end organ damage, defined as referral to cardiology, nephrology, or endocrinology, and/or orders for echocardiogram, ECG, or renal ultrasound.	6 months
Participants With Appropriate Lifestyle Referral	Appropriate lifestyle referral is defined as referral to dietitian, weight loss, or exercise program within 6 months of meeting criteria for incident hypertension.	6 months
