Teaching the patient with ischemic heart disease: a systemic approach to instructional design

Area of Science:

• Cardiology
• Medical Education
• Health Psychology

Background:

• Ischemic heart disease (IHD) requires comprehensive patient education for effective management.
• Existing educational strategies for IHD patients may not be systematically designed or evaluated.
• The need for evidence-based instructional methods to improve patient understanding and adherence.

Purpose of the Study:

• To evaluate the effectiveness of a systematically designed self-instructional program for patients with ischemic heart disease (IHD).
• To determine if this educational approach improves immediate knowledge and long-term retention of disease and treatment information.
• To assess the applicability of an established instructional framework to IHD patient education.

Main Methods:

• A randomized controlled trial involving 100 hospitalized IHD patients (myocardial infarction or unstable angina).
• Experimental group received a linear self-instructional program; control group did not.
• Pretesting, immediate posttesting, and retention testing (14 days post-discharge) were conducted.

Main Results:

• Patients completing the self-instructional program demonstrated significantly higher posttest scores (P < 0.001).
• The program led to significantly better retention of information two weeks after discharge.
• A significant patient effect was observed, indicating individual differences in learning outcomes.

Conclusions:

• A systematic approach to designing patient instruction is effective for improving knowledge in IHD patients.
• The instructional framework used is applicable to patient education for ischemic heart disease.
• This study supports the development and implementation of structured educational programs for cardiovascular disease management.
