Insights

Low medication adherence in older adults with hypertension is a significant issue. Factors like the number of medications, financial status, and patient-physician relationships influence adherence, highlighting areas for intervention.

Area of Science:

  • Gerontology
  • Cardiovascular Medicine
  • Health Services Research

Background:

  • Hypertension (HTN) is a major global health concern, increasing stroke and heart disease risks, especially in older adults.
  • Antihypertensive medications are crucial for blood pressure control and complication prevention.
  • Low medication adherence rates in older adults with HTN pose a significant challenge to effective disease management.

Purpose of the Study:

  • To systematically identify and synthesize factors influencing medication adherence in older adults diagnosed with hypertension.
  • To provide evidence-based insights for developing targeted interventions to improve adherence.

Main Methods:

  • Systematic literature search using PRISMA guidelines across PubMed, MEDLINE, and Google Scholar (July 2022).
  • Convergent integrated analysis framework from the Joanna Briggs Institute for data synthesis.
  • Inclusion of 13 studies after screening 448 initial articles.

Main Results:

  • Fifteen themes influencing medication adherence were identified.
  • Most prevalent factors include: number of medications (53.9%), financial status (38.5%), sex (38.5%), age (30.1%), disease duration (23.1%), comorbidities (23.1%), and health compliance (23.1%).
  • Other identified themes include education, health literacy, beliefs, self-efficacy, and social support.

Conclusions:

  • Findings underscore critical areas for developing innovative, evidence-based programs to enhance medication adherence in hypertensive older adults.
  • Improved adherence can lead to better health outcomes and prevention of serious complications associated with hypertension.

Drug Therapy01:28

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Errors occurring during blood pressure monitoring

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 and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
