Summary
This study explores using SMS text messaging and home blood pressure monitoring (HBPM) to improve medication adherence and blood pressure control in older adults with low socioeconomic status. Findings will inform larger trials on eHealth for this underserved population.
Area of Science:
- Cardiovascular Medicine
- Digital Health
- Health Disparities
Background:
- Low adherence to antihypertensive medication is a key barrier to blood pressure control.
- Older adults with low socioeconomic status are disproportionately affected by uncontrolled hypertension.
- SMS text messaging and home blood pressure monitoring (HBPM) show promise for improving adherence.
Purpose of the Study:
- To evaluate the feasibility of an SMS-based randomized controlled trial for older, low socioeconomic status adults with uncontrolled hypertension.
- To assess patient recruitment, retention, and usability of an SMS intervention.
- To estimate the effect of an SMS approach on blood pressure and medication adherence.
Main Methods:
- Recruitment of 24 low socioeconomic status patients with uncontrolled hypertension and low medication adherence.
- Random assignment to either SMS and HBPM or usual care and HBPM groups.
- Weekly SMS messages for adherence and HBPM assessment; clinicians blinded to group assignment.
Main Results:
- Study funded July 2020; 6 participants enrolled as of May 2021.
- Feasibility and acceptability of the SMS approach are under evaluation.
- Hypothesized improvements in medication adherence and blood pressure control are being tested.
Conclusions:
- Findings will guide the design of larger efficacy trials for eHealth interventions.
- The study targets a high-morbidity population traditionally underrepresented in clinical trials.
- This research advances eHealth delivery systems for older adults with low socioeconomic status.

01:25Errors occurring during blood pressure monitoring
1.1K
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.

166
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...

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...
