Abstract
Background
Comprehensive antimicrobial use (AMU) data are essential to promote effective antimicrobial stewardship. However, qualitative information on AMUs in Japanese hospitals is limited.
Aim
To provide an overview of AMU for inpatients in Japanese hospitals.
Methods
A multi-centre point-prevalence survey was conducted across Aichi Prefecture in 2020, collecting patient demographics, underlying conditions, indications of AMU (for treatment of community-acquired infections (CAIs)/healthcare-associated infections (HAIs), surgical prophylaxis (SP), medical prophylaxis (MP) and others), treated infections, and antimicrobial stewardship team (AST) intervention.
Findings
Among the 10,199 patients from 27 hospitals included in this study, a total of 3738 antimicrobials were prescribed to 3024 patients (29.6%; 95% confidence interval: 28.8–30.5). Of these, 1510 (40.4%) antimicrobials were prescribed for CAI treatment, 815 (21.8%) for HAI treatment, 745 (19.9%) for SP, and 639 (17.1%) for MP. SP administration over 2 days was observed in 31.2% of the cases. The top three prescribed antimicrobials were cefazolin (12.0%, 450), ceftriaxone (9.2%, 343), and oral trimethoprim–sulfamethoxazole (8.7%, 327). AMU per 1000 patients was highest in extra-large hospitals (472) and lowest in small hospitals (264). Ceftriaxone was most commonly prescribed for CAIs, while meropenem was typical for HAIs. AST intervention rates were 15.0% and 22.5% in CAIs and HAIs, respectively.
Conclusion
This study provides comprehensive AMU information from a region in Japan, highlighting variations linked to hospital size, frequent prescriptions of broad-spectrum antimicrobials for HAIs, high prescription rate of trimethoprim–sulfamethoxazole as MP, and prolonged SAP.
期刊介绍:
The Journal of Hospital Infection is the editorially independent scientific publication of the Healthcare Infection Society. The aim of the Journal is to publish high quality research and information relating to infection prevention and control that is relevant to an international audience.
The Journal welcomes submissions that relate to all aspects of infection prevention and control in healthcare settings. This includes submissions that:
provide new insight into the epidemiology, surveillance, or prevention and control of healthcare-associated infections and antimicrobial resistance in healthcare settings;
provide new insight into cleaning, disinfection and decontamination;
provide new insight into the design of healthcare premises;
describe novel aspects of outbreaks of infection;
throw light on techniques for effective antimicrobial stewardship;
describe novel techniques (laboratory-based or point of care) for the detection of infection or antimicrobial resistance in the healthcare setting, particularly if these can be used to facilitate infection prevention and control;
improve understanding of the motivations of safe healthcare behaviour, or describe techniques for achieving behavioural and cultural change;
improve understanding of the use of IT systems in infection surveillance and prevention and control.
