|September 8, 2025
Summary
A new web application, COACH, was developed to help patients manage high blood pressure (hypertension) through home monitoring and collaboration with healthcare teams. Early results show improved usability and blood pressure control.
Area of Science:
- Digital Health Interventions
- Cardiovascular Disease Management
- Health Informatics
Background:
- Hypertension is a major cause of morbidity and mortality.
- Clinical decision support (CDS) tools aid hypertension management.
- Patient-facing CDS requires careful design for usability.
Purpose of the Study:
- To design, develop, and optimize a patient-facing CDS application for hypertension management.
- To emphasize home-based monitoring and patient-provider collaboration.
- To create an engaging digital health intervention for controlling high blood pressure.
Main Methods:
- Iterative, user-centered design process.
- Development using JAVA and SMART on FHIR technologies.
- Extensive testing for validation and optimization.
Main Results:
- Completed development of the COACH web application.
- Demonstrated increased usability and addressed data quality concerns.
- Showed improved blood pressure control in a pilot study.
Conclusions:
- User-centered design enabled the development of a novel hypertension management tool.
- The COACH application provides patient-centered CDS using medical record and home monitoring data.
- Ongoing multisite clinical trials are evaluating the tool's effectiveness.

366
The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.

01:25Errors occurring during blood pressure monitoring
1.3K
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

01:28Hypertension I: Introduction
748
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...
