Abstract Objective: Antimicrobial stewardship programs (ASPs) are designed to optimize antimicrobial use for healthcare facilities and are required at all acute care and critical access hospitals (CAHs). However, rural CAHs often lack the resources to implement robust ASPs. The purpose of this study was to evaluate the impact of adding regional remote antimicrobial stewardship services across a 14-hospital system consisting of one acute care and thirteen CAHs. Methods: Remote ASP expansion consisted of adding an infectious disease (ID) pharmacist and two ID physicians (0. 3 FTE) to provide daily stewardship activities including prospective feedback on antibiotic optimization and use education through remote chart review and communication. Antimicrobial utilization, cost savings, and Clostridioides difficile infection (CDI) rates were tracked. Intervention data and acceptance rates were also collected. Results: In the first twelve months following regional remote stewardship expansion, the ASP demonstrated a 619, 053. 97 reduction (56% decrease in Antibiotic Cost/CMI adjusted patient days) in antimicrobial expenses. While only aztreonam use was significantly reduced at the acute care facility (P <. 01), the use of vancomycin, meropenem, linezolid, and aztreonam decreased by 33%, 31%, 18%, and 35%, respectively, among the CAHs (P <. 001). A 53% reduction in CDI rates was observed across the health system (P <. 01). The program averaged 92 interventions per month, with an overall intervention acceptance rate of 86%. Conclusions: Remote ASPs represent a viable strategy for extending antibiotic stewardship expertise to resource-limited settings to achieve financial and clinical benefits.
