Role of community pharmacists in managing hypertension and diabetes: a patient-centered approach

Abstract

Background: Type 2 diabetes mellitus (T2DM) and hypertension are leading causes of cardiovascular morbidity and mortality worldwide. Community pharmacists offer an accessible, localized solution for bridging chronic disease treatment gaps. Despite this potential, pharmacist-led patient-centered care for these comorbidities remains under-researched in low-and middle-income settings.

Purpose: This study critically assessed clinical, behavioral, and financial outcomes of community pharmacist-led interventions in patients with hypertension and/or T2DM using a patient-centered care model.

Methods: A mixed-methods cross-sectional study was conducted across 12 community pharmacies over six months. In all, 450 adult patients (>18 years) diagnosed with hypertension, T2DM, or both were recruited. Structured interventions included medication therapy management (MTM), adherence counseling, disease-state education, and self-monitoring training. Systolic and diastolic blood pressure, HbA1c, and fasting blood glucose were measured at baseline and three-month follow-up. Patient satisfaction was assessed using a 10-item Likert scale.

Findings: Significant improvements were observed post-intervention. Mean systolic blood pressure declined from 158.4 ± 14.2 to 138.7 ± 11.6 mmHg (p < 0.001), and HbA1c decreased from 8.6 ± 1.1% to 7.4 ± 0.9% (p < 0.001). Medication adherence and patient satisfaction scores improved by 36.2 and 31.0 points, respectively. Key barriers included poor reimbursement frameworks, absence of integrated health records, and ineffective inter-professional collaboration.

Conclusion: Community-based pharmacist interventions significantly improved clinical outcomes and patient satisfaction in patients with hypertension and diabetes. Integrating pharmacist-led care into patient-centered models through policy reform and digital health holds strong potential for global chronic disease management.
