  • Background: Alarming trends in antibiotic resistance have sparked a National Action Plan endorsing antimicrobial stewardship programs (ASP) in healthcare facilities.  Carolinas HealthCare System provides care in 3 states and in varied settings - ranging from critical access facilities to large academic and community medical centers as shown in Figure 1.

    ASP also vary by facility, ranging from mature programs to those taking first steps.  We sought to establish an ASP framework across 28 acute-care hospitals, utilizing varying clinical information systems, by uniting local resources with an advisory team led by a medical director, two clinical pharmacists, and a data analyst. 

    Methods:   In Fall 2015 each facility chose a pharmacist, physician, and administrative ASP champion.  Days of therapy (DOT) per 1000 patient days was adopted for monitoring select antibiotics monthly.  Baseline usage data from September 2014 – August 2015 was collected.  A gap analysis survey of CDC Core ASP Elements was conducted to stratify facilities into 3 tier-levels (1,2, and 3) with 1 having the most comprehensive ASP.  Target and stretch DOT reduction goals were set for each facility.  Site visits were conducted in winter 2016, 3 – 4 major goals set, and a post-visit summary provided.  Pharmacists set up monthly facility meetings to assess progression, and a bi-monthly virtual meeting for sharing best practices.  Curriculum for an ASP symposium was developed based on global educational needs.

    Results:  Data (DOT/1000 patient days) on 17 selected antibiotics were collected in 28 acute-care hospitals for each month between September 2014 and present.  Reduction goals by tier are shown in table 1.

    Goal progression by tier is shown in Figure 2, with some early, modest decline in use metrics.

    Conclusion:  Building a unified ASP framework across a diverse system presents many challenges, but appears feasible based on our early work.  More work is needed to establish a national ASP benchmark.
