1148. Antimicrobial Stewardship Program at a Long-term Care Hospital for Severely Handicapped Children and Adults

BACKGROUND: Although antimicrobial stewardship program (ASP) is also recommended for a long-term care facility (LTCF), research on ASP in LTCFs is still limited. Our study was conducted at an LTCF offering chronic medical care for pediatric and adult patients with extensive medical needs since childhood. Our aim of this study was to evaluate the impacts of ASP in an LTCF. METHODS: A quasi-experimental study was conducted at Tokyo Metropolitan Fuchu Ryoiku Medical Center (250 beds) in Japan. The pre- and post-intervention periods were from April 2013 to March 2017 and April 2017 to March 2019, respectively. Periodic educational interventions were conducted throughout study period. ASP in post-intervention period consisted of mandatory consultation with infectious diseases service at an outside children’s hospital for prescription of restricted drugs. Fluoroquinolones, cefepimes, carbapenems and vancomycin were listed as restricted drugs. Intravenous and oral antimicrobial use was calculated by day of therapy (DOT) per 1,000 patient-days. Interrupted time series analysis was used for level and trend change for pre- and post-intervention periods. RESULTS: Oral agents comprised 89% of the total antimicrobial use. Oral antimicrobials were decreased by 39% in post-intervention with significant level change (P < 0.01) and without trend change (P = 0.61) (Figure 1). Among oral antimicrobials, macrolides, fluoroquinolones and third-generation cephalosporins were decreased by 72% in post-intervention with significant level change (P < 0.01) and without trend change (P = 0.42) (Figure 2). Intravenous antimicrobials were decreased by 40% without level change (P = 0.15) and trend change (P = 0.65) (Figure 3). CONCLUSION: Combining education and mandatory consultation with infectious diseases service for restricted drug enhanced in decreasing total oral antimicrobials at an LTCF.
