Abstract
Antimicrobial resistance remains a growing global threat, disproportionately impacting underserved rural communities in the United States with limited access to pharmacy services. This meta review synthesizes evidence on community-led telepharmacy antimicrobial stewardship programs and evaluates their impact on antibiotic prescribing practices, resistance patterns, and alignment with Sustainable Development Goals. The objective is to determine the clinical, economic, and equity outcomes associated with telepharmacy-supported stewardship in rural United States healthcare settings. From 8,742 identified records, 20 studies met the inclusion criteria spanning telepharmacy implementation, antimicrobial stewardship outcomes, prescribing patterns, and policy frameworks. Studies published between 2005 and 2021 provided quantifiable metrics on clinical, economic, and equity-related outcomes. Inappropriate antibiotic use decreased by 28.6% (95% CI 21.3 to 35.9, p<0.001), and odds of appropriate prescribing improved significantly (OR 3.21, 95% CI 2.54 to 4.06). Broad spectrum utilization declined by 32.4%, guideline concordant selection improved by 41.2%, medication errors decreased by 94% (OR 0.06, 95 percent CI 0.03 to 0.12), and antibiotic de-escalation rates nearly doubled (34% to 67%). Hospitals integrating telepharmacy stewardship experienced reduced length of stay (mean 1.8 days, 95% CI 1.2 to 2.4, p<0.001) and 41% fewer Clostridium difficile infections (IRR 0.59, 95 percent CI 0.43 to 0.81). Days of therapy per 1,000 patient days decreased by 89.7 days (95% CI 67.2 to 112.3). Programs demonstrated cost savings of 3.45 dollars per dollar invested (95% CI 2.89 to 4.01). Annual savings averaged 487,000 dollars per facility, and cost per prescription decreased by 47.30 dollars. Cost avoidance from prevented resistance-related complications totaled 1.2 million dollars annually per 200-bed facility. Telepharmacy increased rural pharmaceutical care accessibility (OR 2.71, 95% CI 2.03 to 3.62, p<0.001). Preventive service use increased by 23.4%, and equity index scores improved by 18.6 points, demonstrating alignment with Sustainable Development Goals 3 and 10. Program retention reached 83.4% at two years, with provider acceptance of 89.7% and improved staff satisfaction (mean increase 2.2 points, p<0.001). Community-led telepharmacy antimicrobial stewardship programs represent cost-effective interventions that address antimicrobial resistance, improve clinical outcomes, reduce healthcare costs, and advance equity in rural United States communities. Evidence supports broader implementation with attention to regulatory policy, technological capacity, and long-term stakeholder engagement.
