2032. First National Survey of Antimicrobial and Antifungal Stewardship in Japan.

Background To manage antimicrobial resistance, both antimicrobial stewardship (AMS) and antifungal stewardship (AFS) are needed. However, limited data show AMS and AFS practices among hospitals in Japan. Methods We conducted a cross-sectional nationwide study using a questionnaire distributed to hospitals that participated in a hospital epidemiology workshop in Japan in July 2018. The questions addressed activities of preauthorization, notification, and intervention within 7 or 28 days about broad-spectrum antibiotics (third- and fourth-generation cephalosporins and piperacillin–tazobactam, carbapenem, intravenous quinolone) and antifungals. Interventions to use broad-spectrum antibiotics and antifungals were compared between large (≥501 beds) and small/medium-sized (≤500 beds) hospitals. Results Of 240 hospitals, 39 (16%; 18 large and 21 small/medium-sized) responded. Preauthorization of using broad-spectrum antibiotics and antifungals was found in 4 (10%) and 1 (3%) hospital(s), respectively. Notification of broad-spectrum antibiotics and antifungals was found in 37 (95%) and 2 (5%) hospitals, respectively. The numbers of hospitals that intervened in the use of broad-spectrum antibiotics within 7 and 28 days were 17 (44%) and 34 (87%), respectively; those of antifungals were 3 (8%) and 10 (26%), respectively (Table 1). Interventions to use broad-spectrum antibiotics within 7 days were statistically more frequent in small-/medium-sized hospitals than in large hospitals [13 (61.9%) vs. 4 (22.2%),odds ratio = 5.7, 95% confidence interval = 1.4–23.3, p = 0.023]. All hospitals had less-frequent interventions to use antifungals within 7 days than those for antibiotics[3 (14.3%) vs. 0 (0%)] (Table 2). Conclusion Small-/middle-sized hospitals had more frequent interventions within 7 days of broad-spectrum antibiotics than those of large hospitals, possibly because small-/medium-sized hospitals are agile and have few barriers against interventions to use broad-spectrum antibiotics. Compared with broad-spectrum antibiotics, interventions of antifungals were less frequently conducted in all hospitals. We need to emphasize the importance of AFS in Japan. Further studies on related factors are needed. Disclosures All authors: No reported disclosures. [ABSTRACT FROM AUTHOR]
