Abstract

Objective: Healthcare-associated infections (HAIs) pose significant challenges to healthcare systems worldwide. Epidemiological data are essential for effective HAI control; however, comprehensive information on HAIs in Japanese hospitals is limited. This study aimed to provide an overview of HAIs in Japanese hospitals.

Methods: A multicenter point-prevalence survey (PPS) was conducted in 27 hospitals across the Aichi Prefecture between February and July 2020. This study encompassed diverse hospital types, including community, university, and specialized hospitals. Information on the demographic data of the patients, underlying conditions, devices, HAIs, and causative organisms was collected.

Results: A total of 10,199 patients (male: 5,460) were included in this study. The median age of the patients was 73 (interquartile range [IQR]: 56-82) years, and the median length of hospital stay was 10 (IQR: 4-22) days. HAIs were present in 6.6% of patients, with pneumonia (1.83%), urinary tract infection (1.09%), and surgical site infection (SSI) (0.87%) being the most common. The prevalence of device-associated HAIs was 0.91%. Staphylococcus aureus (17.3%), Escherichia coli (17.1%), and Klebsiella pneumoniae (7.2%) were the primary pathogens in 433 organisms; 29.6% of the Enterobacterales identified showed resistance to third-generation cephalosporins. Pneumonia was the most prevalent HAI in small-to-large hospitals (1.69%-2.34%) and SSI, in extra-large hospitals (over 800 beds, 1.37%).

Conclusions: This study offers vital insights into the epidemiology of HAIs in hospitals in Japan. These findings underscore the need for national-level PPSs to capture broader epidemiological trends, particularly regarding healthcare challenges post-COVID-19.

日本医院中的医源性感染：2020 年爱知县大规模多中心点流行率调查结果。

目的：医疗相关感染（HAIs）给全球医疗系统带来了巨大挑战。流行病学数据对于有效控制 HAI 至关重要；然而，有关日本医院 HAI 的全面信息却很有限。本研究旨在提供日本医院 HAIs 的概况：方法：2020 年 2 月至 7 月期间，在爱知县的 27 家医院开展了多中心点流行率调查 (PPS)。这项研究涵盖了不同类型的医院，包括社区医院、大学医院和专科医院。研究收集了患者的人口统计学数据、基础疾病、设备、HAIs 和致病菌等信息：本研究共纳入 10,199 名患者（男性：5,460 名）。患者年龄中位数为 73 岁（四分位数间距 [IQR]：56-82），住院时间中位数为 10 天（四分位数间距 [IQR]：4-22）。6.6%的患者存在 HAIs，其中最常见的是肺炎（1.83%）、尿路感染（1.09%）和手术部位感染（SSI）（0.87%）。设备相关的 HAI 感染率为 0.91%。金黄色葡萄球菌（17.3%）、大肠埃希菌（17.1%）和肺炎克雷伯菌（7.2%）是 433 个病原体中的主要病原体；29.6% 的肠杆菌对第三代头孢菌素产生耐药性。肺炎是小到大型医院中最常见的 HAI（1.69%-2.34%），而 SSI 则是特大型医院中最常见的 HAI（800 张病床以上，1.37%）：这项研究为了解日本医院的 HAI 流行病学提供了重要依据。这些发现突出表明，国家级 PPSs 需要捕捉更广泛的流行病学趋势，尤其是 COVID-19 后的医疗保健挑战。
