Clinical Pharmacy Services (CPS) in Resource-Limited Settings

Abstract

Clinical pharmacy services (CPS) are integral to optimizing medication use, improving therapeutic outcomes, and enhancing patient safety within healthcare systems. While well established in high-income countries, the implementation of CPS in resourcelimited settings faces significant challenges, including inadequate infrastructure, workforce shortages, limited access to medicines, and weak health system governance. Despite these barriers, growing evidence suggests that structured clinical pharmacy interventions can substantially improve health outcomes even in low-resource environments. This review explores the current status, opportunities, and challenges of clinical pharmacy services in resource-limited settings. It highlights core CPS activities, such as medication therapy management, adverse drug reaction monitoring, antimicrobial stewardship, patient counseling, and pharmacovigilance, and evaluates their impact on patient care. Special emphasis is placed on innovative service models that maximize limited resources, including task shifting, interprofessional collaboration, and the integration of technology-enabled solutions such as telepharmacy and mobile health platforms. The review also discusses policy frameworks, training initiatives, and donor-supported programs that have facilitated CPS adoption in selected regions. Despite promising advances, barriers such as insufficient clinical training, lack of regulatory support, and cultural resistance remain pervasive. Sustainable implementation of CPS requires investment in pharmacist capacity building, local adaptation of international best practices, and stronger health policies that recognize pharmacists as essential members of the healthcare team. By synthesizing current evidence, this review underscores the potential of clinical pharmacy services to improve patient care in resource-limited settings and provides strategic directions for scaling up their adoption to achieve universal health coverage.
