COACH: Collaboration Oriented Approach to Controlling High Blood Pressure
Study Details
Study Description
Brief Summary
Hypertension is a significant contributor to poor cardiovascular outcomes. Self-management support tools can increase patient behaviors to improve blood pressure. We created a clinical decision support app, called COACH, to integrate home blood pressure data and goals into EHR reporting and workflow with communications informed by behavioral economics principles to support shared decision-making. The study aims to measure the effectiveness of the COACH intervention in a pragmatic multi-site randomized trial in a primary care setting.

Detailed Description
This protocol addresses the challenge of implementing scalable, interoperable clinical decision support (CDS) and the patient-centered outcome of avoiding heart attacks and strokes through high blood pressure control in the setting of multiple chronic illnesses. It leverages substantial extant work to build patient-centered CDS for high blood pressure, electronic care planning and health coaching at scale, implementing and testing these tools in new primary care settings. Significantly, this proposal will implement a new patient-facing CDS across multiple clinic sites spanning three major health systems and in the nation's two leading EHR vendor platforms. Controlling blood pressure is a singularly important goal; nearly 50% of adults in health care have high blood pressure, which increases their risk of heart attack and stroke. However, managing blood pressure requires navigation within a narrow therapeutic index, where overtreatment leads to substantial complications, including kidney damage, low blood pressure, falls, and mood disorders. Balancing treatment to reduce risk while avoiding harm requires engaging patients directly in intensive goal setting, shared care planning around nonpharmacologic and pharmacologic treatments, and self-monitoring for effectiveness and adverse events.
Hypertension rarely occurs alone; providing clinical decision support, care planning, and self-management support in the context of multiple chronic illnesses is required.
We will address patient-centered needs by scaling our implemented, patient-facing CDS for eCare Planning, Collaboration Oriented Approach to Controlling High blood pressure (COACH) to 3 sites and testing whether it reduces blood pressure and risk of heart attack and stroke. To do so, we embed a diverse patient perspective into a robust, feasible, and effective CDS implementation and evaluation process by 1) capturing patient input throughout the CDS lifecycle; 2) adapting the COACH CDS to patient preferences, values, and goals; and 3) disseminating the tested FHIR-based (Fast Healthcare Interoperability Resources) patient-facing application into organizations that combines blood pressure control with relevant risk scores into an eCare Plan application and framework and implementing these patient-centered approaches in feasible, context-responsive, and effective ways. We address scalability by helping organizations advance their use of patient generated health data and patient reported outcomes using standard implementation frameworks while producing CDS artifacts and implementation guides that can be leveraged to increase adoption beyond the work of this proposal. For interoperability, we use a standard-based, structured process that re-uses concept and value sets whenever possible while using robust techniques to develop new sets and make them available for future innovators.
To complete these goals, we leverage our previous work in building standardized HBP value sets, logic, and a patient-facing FHIR tool. In this work, we have engaged in several collaborations, most notably with the CDS Connect Community, where we will upload all artifacts, but also with other AHRQ digital health efforts and with other large collaboratives, including the ACC/AHA and JNC8 guideline developers, the HL7 CPG-on-FHIR, and the eCare Planning project from NIDDK and AHRQ. We describe how we will engage these collaborations to disseminate our artifacts and implementation guides and get feedback as to the most robust approach. We will use two frameworks to evaluate the implementation. First, adaptation in implementation science is both common and may be required for success; we explore the ways in which the 5 rights-the right information to the right person in the right intervention format through the right channel at the right time in workflow-can be adapted for key organizational needs while retaining fidelity to the goals. In addition, we consider a framework that combines usability with effectiveness for complex conditions by exploring concepts related to appropriate simplicity, prioritization, summarization, adjudication, and actionability to enhance CDS effectiveness for patient needs.
Thus, our specific aims are:
-
To refine and implement a patient-facing, adaptable Blood Pressure Control CDS system in 3 diverse settings, using implementation science and patient engagement to maximize effectiveness.
-
To evaluate the effectiveness of the application at lowering blood pressure employing a mixed methods design, with qualitative inquiry nested within a randomized controlled trial, secondary RE-AIM and social cognitive theory outcomes, and qualitative evaluation of implementations across sites.
-
To develop robust, sharable, interoperable mechanisms, leveraging collaborations and synthesis of the implementation experience to aid in further dissemination and implementations of patient-facing CDS.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Enhanced COACH Enhanced blood pressure management recommendations that use cognitive and behavioral science to increase the likelihood of self-management goal setting to lower blood pressure. The CDS tool allows participant access to BP visualizations, reminders, and affectively tailored messaging about blood pressure management. |
Other: Enhanced COACH CDS Tool
CDS tool with features to promote high blood pressure management
|
| Active Comparator: Usual Care COACH Equivalent of usual care delivered through the CDS tool: Blood pressure management with basic information, reduced reminders, and no affective alerts. |
Other: Usual Care COACH CDS Tool
CDS tool with limited features to promote high blood pressure management

Outcome Measures
Primary Outcome Measures
- Blood Pressure Control [Up to 6 months]
Percent of participants at or below 140/90 (office BP) or 135/85 (home BP) average.
Secondary Outcome Measures
- Reduction in Systolic and/or Diastolic Blood Pressure [Up to 6 months]
Percent of participants displaying a decrease in systolic and/or diastolic blood pressure readings over the 6-month course of measurement
- Demographic factors contributing to blood pressure control [Up to 6 months]
Age- and socioeconomic status-reported participant data
- COACH Application System Usability Evaluation [Up to 6 months]
Participant assessment of application using the System Usability Scale questions using 4-point scale for 10 agreement questions where low scores indicate less agreement and high scores are higher agreement of usability of the application
- 5. Participant report of health behaviors including Self Efficacy, Social Support, Outcome Expectations and Self-regulation [2 months, 6 months]
Participant self-report of factors related to health beliefs using 100-point sliding scale for 25 agreement questions where low scores indicate less agreement and high scores are higher agreement of aspects of health beliefs
