ECHO-COPD: Impact of a Pharmacist-Led Health Belief Model-Based Educational Intervention Among COPD Patients (ECHO-COPD)

7 september 2026 bijgewerkt door: Rabia Hussain

Impact of a Pharmacist-Led Health Belief Model-Based Educational Intervention on Medication Adherence, Quality of Life, and Direct Cost Among COPD Patients at Buraidah Central Hospital in Al-Qassim Region, Saudi Arabia: A Quasi-Experimental Design

Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease associated with substantial morbidity and mortality, impaired quality of life, and healthcare costs. Medication adherence and appropriate self-management are important components of COPD management; however, patients' health beliefs and perceptions may influence their adherence to treatment and engagement in recommended health behaviours. This study aims to evaluate the impact of a pharmacist-led educational intervention based on the Health Belief Model (HBM) on medication adherence, quality of life, and direct healthcare costs among patients with COPD receiving care at Buraidah Central Hospital (BCH) in Al-Qassim Region, Saudi Arabia.

A quantitative, quasi-experimental pretest-posttest control-group design will be used. Eligible COPD patients will be non-randomly assigned to either an intervention group or a control group. The intervention group will receive structured, pharmacist-led HBM-based educational sessions in addition to routine care. In contrast, the control group will continue to receive standard care without additional educational input. Baseline assessments will include medication adherence using the 8-item Morisky Medication Adherence Scale (MMAS-8); quality of life and health status using the COPD Assessment Test (CAT); health beliefs using a structured HBM questionnaire; and direct medical costs obtained from the hospital clinical cost centre. The educational intervention will be delivered over six months, followed by post-intervention assessment using the same outcome measures.

Gedetailleerde beschrijving

The HBM will guide the content and delivery of the pharmacist-led educational intervention. The intervention will address the six core constructs of the HBM:

  1. Perceived susceptibility
  2. Perceived severity
  3. Perceived benefits
  4. Perceived barriers
  5. Cues to action
  6. Self-efficacy The purpose of applying the HBM is to influence patients' understanding of COPD and promote positive behavioural changes, particularly improvements in medication adherence. The study will then examine the relationship between these improvements and quality of life, healthcare utilisation, and direct healthcare costs.

The intervention will consist of structured face-to-face educational sessions conducted in the designated counselling room of the Pulmonary Department at BCH. Sessions will incorporate printed educational materials, lectures, counselling, practical demonstrations, motivational support, problem-solving strategies, and reinforcement of behavioural changes.

The educational programme will cover aspects of COPD management, medication adherence and appropriate medication use, COPD risk factors and complications, nutrition and preventive care, smoking cessation, barriers to recommended behaviours, cues to action, and strategies to improve patients' confidence in managing COPD.

Participants in the intervention and control groups will undergo pre-intervention assessments. Participants in the intervention group will subsequently receive the structured educational programme, while the control group will continue to receive standard care without additional educational input. Post-intervention assessments will use the same measurement instruments to allow within-group and between-group comparisons.

  • Individual counselling
  • Practical demonstrations
  • Personalised feedback
  • Problem-solving strategies
  • Motivational support
  • Interactive activities
  • Peer group discussions
  • Reinforcement of behavioural changes The six HBM constructs will guide the educational content.
