Antimicrobial Stewardship Programs and the Role of Pharmacists in Combating Antibiotic Resistance: A Narrative Review from the Department of Pharmacy, Najran University

Abstract

Antibiotic resistance represents one of the most critical public health challenges of the twenty-first century, threatening the efficacy of treatments for infectious diseases and placing enormous burden on healthcare systems worldwide. Antimicrobial Stewardship Programs (ASPs) have emerged as a cornerstone strategy for optimizing antibiotic use, reducing resistance rates, and improving patient outcomes. Pharmacists, as medication experts embedded within interprofessional healthcare teams, occupy a uniquely influential position within these programs. This paper examines the theoretical underpinnings, practical structures, and clinical impact of ASPs, with particular emphasis on the multifaceted contributions of pharmacists — from prospective audit and feedback to formulary management, pharmacokinetic monitoring, and patient education. The paper further contextualizes ASP implementation within the Kingdom of Saudi Arabia's healthcare reform agenda under Vision 2030, addressing the roles of the Saudi Commission for Health Specialties (SCFHS), the Central Board for Accreditation of Healthcare Institutions (CBAHI), and international frameworks such as the Joint Commission International (JCI) standards. Evidence from both global and regional literature is synthesized to demonstrate that pharmacist-led stewardship interventions are associated with significant reductions in antibiotic consumption, resistance emergence, Clostridioides difficile infections, and healthcare costs, while simultaneously enhancing antibiotic appropriateness and patient safety.
