Nationwide cross-sectional study of antimicrobial stewardship and antifungal stewardship programs in inpatient settings in Japan

BMC Infect Dis. 2021 Apr 16;21(1):355. doi: 10.1186/s12879-021-06035-5.


BACKGROUND: To prevent antimicrobial resistance, both antimicrobial stewardship (AMS) and antifungal stewardship (AFS) in inpatient settings are needed in small/middle-sized hospitals as well as large hospitals.

METHODS: We conducted the web-based, self-administered, nationwide cross-sectional study regarding AMS and AFS in inpatient settings in Japan, targeting hospitals that participated in a hospital epidemiology workshop conducted in July 2018. The questionnaire was composed of intervention protocols for use of broad-spectrum antimicrobials and antifungals within 7 or 28 d of beginning usage. These broad-spectrum antimicrobial and antifungal protocols were compared between large (≥501beds) and small/middle-sized (≤500 beds) hospitals.

RESULTS: Of 240 hospitals surveyed, 39 (16%; 18 large and 21 small/middle-sized) responded. The number of hospitals that intervened in the use of broad-spectrum antimicrobials within 7 and 28 d were 17 (44%) and 34 (87%), respectively; those that intervened for antifungals were 3 (8%) and 10 (26%), respectively. Interventions for use of broad-spectrum antimicrobials within 7 d were significantly more frequent in small/middle-sized hospitals compared to large hospitals [13 (61. 9%) vs. 4 (22. 2%), odds ratio = 5.7, 95% confidence interval = 1.4-23.3, p = 0.023].

CONCLUSIONS: Small/middle-sized hospitals had more frequent interventions within 7 d of broad-spectrum antimicrobial use than large hospitals. More effort to improve AFS is needed among all hospitals.
