The Feasibility of a Web-based Application to Monitor Home Blood Pressure

March 4, 2020 updated by: Holly J. Mattix-Kramer, Loyola University
Control of hypertension remains one of the most important interventions available to clinicians to reduce risk of cardiovascular disease, kidney disease and stroke. Self-measured home blood pressure monitoring plus additional support has been shown to reduce blood pressure in adults with previously uncontrolled hypertension. Most previous studies have utilized healthcare personnel to facilitate communication of home blood pressure levels to physicians and did not provide methods to directly transmit self-measured blood home blood pressure levels to physicians via the electronic health record. Emerging technology now provides the ability for patient's to upload self-measured blood pressure levels into their own medical record which may eliminate the need for additional health personnel. This study will examine the feasibility, patient adherence and physician and patient perceptions of a web-based application which will facilitate direct input of self-measured home blood pressure levels and patient reported symptoms directly into the electronic health record with message alerts to the provider for hypertension management. Up to 10 Loyola primary care physicians and 20 of their respective patients age 50 years and older who have a smart phone device or home computer and have treated hypertension will be enrolled. The study will utilize the existing web-application called MyChart. MyChart is the name of the web-based application and it is not an acronym. Enrolled patients will download the existing MyChart web-based application on their smart phone device or home computer and will record home blood pressure measurements using their home blood pressure machine into their smart phone application. The MyChart application is available to all patients receiving care in the Loyola Health Care System. The blood pressure readings and patient reported symptoms will then be available for their physicians to review within the electronic health record. After using the web-based application for two months, both patients and physicians will be asked to participate in focus groups and interviews, respectively, to determine their perceptions and satisfaction with the web-based application. Data from this feasibility study may be used to guide a future clinical trial of hypertension management that examines the effectiveness of the MyChart web-based application for frequent blood pressure monitoring compared to standard care.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Observational studies and clinical trials have demonstrated that clinicians fail to intensify therapy in hypertensive management despite patients not meeting goal. For this reason, patient centered tools can help facilitate meeting goals with the provider. Web-based communication combined with provider care management successfully lowered blood pressure to <140/90 mm Hg in prior studies of patients with hypertension. Emerging technology now provides the ability for patients to upload self-measured home blood pressure information into their own medical record which may eliminate the need for additional health personnel. This study will investigate the feasibility of health informatics to facilitate better compliance and safety for both provider and patient for hypertension management. The home blood pressure readings along with patient reported symptoms will be recorded using the MyChart, a web-based tool available to all patients receiving care at Loyola University Medical Center. MyChart can be accessed with a hand-held device or home computer. After enrollment, patients will receive a notice every two weeks via MyChart to upload home blood pressure values and patient reported symptoms. This information entered into MyChart by patients will be placed into the electronic health record in a home vital signs flow sheet, which will be separate from the flow sheet of vital signs measured in the clinic. Physicians will receive an alert message when patients upload the blood pressure data. The alert message will provide physicians with the average blood pressure value over the two weeks and will provide simple guidance on whether actions, such as titrating existing medication should be taken (based on whether BP is ≥ 140/90 mmHg). Patients will also be able to track their own home blood pressure values using the MyChart application. As a first step, we are first examining the feasibility of this web-based application and determining the perceptions of both patients and physicians.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes
