  • Background: Community hospitals that wish to improve antimicrobial stewardship (AS) activities face barriers such as lack of dedicated personnel, resources, and/or administrative support. 

    Methods: We conducted an in-depth needs assessment at 10 community hospitals during months 1-2 of enrollment in the Duke Antimicrobial Stewardship Outreach Network (DASON). The DASON liaison pharmacist conducted in-person standardized interviews at each member facility to characterize AS activities and infrastructure at baseline. Results were compiled using descriptive statistics. 

    Results: The 10 participating hospitals had a median [IQR] bed size of 280 [220-310] and 9,849 [7,567-14,424] admissions per year. Infectious diseases (ID) physicians and ID-trained pharmacists were available in 8 (80%) and 5 (50%) facilities, respectively. Three hospitals (30%) provided dedicated PharmD funding for AS; none provided dedicated ID physician funding. Two (20%) facilities had a preexisting formal AS program. Committees with antimicrobial use oversight existed in 6 (60%) facilities, but AS subcommittees (20%) and formalized policies (30%) were uncommon. Ongoing AS activities most commonly included pharmacy-driven dose optimization (100%); empiric antibiotic selection guidelines (90%); auto-stop policies (90%); and IV-PO conversion (70%). Four (40%) hospitals performed post-prescription review; two (20%) used formulary restriction and preauthorization. Three (30%) hospitals conducted regular antimicrobial use evaluations, while 5 (50%) conducted formulary reviews annually. Few hospitals measured or reported outcomes to assess the utility of AS activities. Survey respondents cited multiple barriers to implementation: higher priority IT and clinical initiatives, personnel and staffing constraints, lack of education regarding AS, and opposition from prescribers.

    Conclusion: Formalized programs and dedicated resources for AS were uncommon in community hospitals, despite ongoing AS activities and the presence of ID experts. Outcome measurements and data-driven assessments of the utility of AS activities were lacking. Efforts to support, formalize, measure, and optimize AS programs in community hospitals are greatly needed.
