Insights

Medication adherence in hypertensive patients is crucial for managing high blood pressure. Factors like patient knowledge and provider relationships significantly influence adherence, suggesting a need to focus on behavioral and educational interventions.

Area of Science:

  • Public Health
  • Cardiovascular Medicine
  • Health Behavior

Background:

  • High blood pressure (hypertension) is a significant global health issue.
  • Effective management relies on anti-hypertensive medications.
  • Medication adherence presents a major challenge for hypertensive patients worldwide.

Purpose of the Study:

  • To assess predisposing, enabling, and reinforcing factors influencing medication adherence.
  • Focus on hypertensive patients aged 40-70 years in Gweru urban.
  • Identify key determinants of treatment compliance in this demographic.

Main Methods:

  • Descriptive cross-sectional study design.
  • Convenient sampling of 110 hypertensive patients.
  • Interviewer-administered questionnaire based on the PRECEDE model (Phase 4).

Main Results:

  • Significant associations found between medication adherence and age (P=0.0059), marital status (P=0.015), monthly income (P=0.0002), support groups (P=0.027), and patient knowledge (P=0.0058).
  • Modal age was 70 years; mean age was 58 years (SD=10.29).
  • Females constituted 61.8% and males 38.2% of the sample.

Conclusions:

  • Enhancing patient knowledge and fostering strong patient-provider relationships are vital for improving medication adherence.
  • Interventions should prioritize modifiable factors like predisposing, enabling, and reinforcing elements.
  • Demographic and socio-economic factors, while associated, may be less amenable to change compared to behavioral and educational interventions.

Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Hypertension V: Nursing Management

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.

Hypertension IV: Drug Therapy and Lifestyle Modifications

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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
