Insights

This study shows that an educational intervention using the BASNEF model significantly improved treatment adherence in patients after coronary artery bypass graft (CABG) surgery. The intervention positively impacted patients

Area of Science:

  • Cardiovascular Surgery
  • Health Education
  • Behavioral Science

Background:

  • Coronary artery bypass graft (CABG) surgery is a critical intervention for cardiovascular disease (CVD).
  • Post-surgical treatment adherence is vital for patient recovery and long-term outcomes.
  • The Belief, Attitudes, Subjective Norms, and Enabling Factors (BASNEF) model offers a framework for health education interventions.

Purpose of the Study:

  • To evaluate the effectiveness of a BASNEF model-based educational intervention on treatment adherence in post-CABG patients.
  • To assess the impact of the intervention on the constructs of the BASNEF model.

Main Methods:

  • A randomized clinical trial involving 72 patients post-CABG, divided into intervention and control groups.
  • The intervention group received four 40-minute educational sessions based on the BASNEF model.
  • Treatment adherence was measured using the Modanloo Adherence to Treatment Questionnaire (MATQ), and BASNEF constructs were assessed using a researcher-made questionnaire. Measurements were taken pre-intervention, post-intervention, and at 3-month follow-up.

Main Results:

  • Significant improvements were observed in the total MATQ scores and subscales for the intervention group compared to the control group (P < 0.050).
  • Mean scores for BASNEF model constructs (knowledge, attitude, behavior intention, subjective norms, enabling factors) significantly increased in the intervention group post-intervention (P < 0.050).

Conclusions:

  • A BASNEF model-based educational intervention effectively enhances treatment adherence in patients following CABG surgery.
  • The intervention positively influenced the core components of the BASNEF model, contributing to improved adherence.

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Angina V: Nursing Management

Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Heart Failure Drugs: &#946;-Blockers01:22

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

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...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
