Design and evaluate a community pharmacy-based medication adherence program

Thesis Abstract

Non-adherence to prescribed medication regimens remains a pervasive challenge in managing chronic diseases, resulting in suboptimal health outcomes, increased healthcare costs, and heightened morbidity and mortality rates. Community pharmacies represent a strategic point of contact for patients within the healthcare system, yet the integration of structured medication adherence interventions in this setting remains underexplored in many contexts. This study aims to design, implement, and evaluate a community pharmacy-based medication adherence program, thereby contributing to improved patient outcomes and healthcare efficiency. Specifically, the study seeks to (1) develop a tailored adherence intervention grounded in the Health Belief Model and the Theory of Planned Behavior, (2) assess its implementation feasibility and acceptability among pharmacy staff and patients, and (3) evaluate its effectiveness in enhancing medication adherence and clinical outcomes over a six-month follow-up period. Employing a mixed-methods research design, the study combines quantitative and qualitative approaches to provide comprehensive insights. The quantitative component adopts a quasi-experimental pre-post design involving a sample of 200 adult patients with chronic conditions such as hypertension and diabetes, recruited from ten community pharmacies. Patients are randomized into intervention and control groups, with the intervention group receiving the adherence program comprising personalized counseling, reminder systems, and follow-up calls, while controls receive standard care. Data collection instruments include validated medication adherence scales (e.g., Morisky Medication Adherence Scale), clinical measurements (blood pressure, blood glucose levels), and prescription refill records. Qualitative data are gathered through semi-structured interviews with pharmacy staff and patient focus groups to explore perceptions of the program’s feasibility and acceptability. Data analysis involves descriptive statistics to characterize the sample, t-tests and chi-square tests to compare adherence and clinical outcomes between groups, and multiple regression analyses to identify predictors of adherence improvement. Thematic analysis is employed to interpret qualitative data, validated through triangulation to ensure methodological rigor. The study hypothesizes that the community pharmacy-based intervention will significantly improve medication adherence levels and clinical parameters compared to standard care, with increased acceptability and feasibility reported by pharmacy staff and patients. Expected findings include a statistically significant increase in adherence scores and improved clinical outcomes, alongside positive perceptions of the program’s practicality. Findings are anticipated to demonstrate that structured, theory-based interventions implemented within community pharmacies can effectively address barriers to medication adherence, such as forgetfulness, lack of understanding, and perceived medication burden. This research contributes novel evidence to the body of knowledge on community pharmacy-led interventions, highlighting their potential to optimize medication management in primary care settings. It offers practical insights into the design and implementation of scalable adherence programs, guided by behavioral theory and customized to local contexts. The study concludes that integration of targeted adherence strategies within community pharmacies can enhance patient health outcomes while providing an economically viable model for healthcare systems. Recommendations include policy support for pharmacist-led adherence programs, continuous staff training, and the development of digital tools for sustained patient engagement. Future research should explore long-term impacts, cost-effectiveness analyses, and the adaptation of such interventions across diverse healthcare environments to promote widespread adoption.
