Australia does not have a national healthcare associated infection (HAI) surveillance program. Only one HAI point prevalence study has been undertaken in 1984. The objective of this study was to estimate the burden of healthcare associated infection (HAI) in acute adult inpatients in Australia.
A cross sectional point prevalence study (PPS) was conducted in a sample of large acute care hospitals. All data were collected by two trained Research Assistants. Surveillance methodology was based on the European Centre for Disease Prevention and Control (ECDC) PPS Protocol with variation in the sampling method in that only acute inpatients ≥ 18 years old were included. ECDC HAI definitions were applied.
Data was collected between August and November 2018. A total of 2767 patients from 19 hospitals were included in the study. The median age of patients was 67, and 52.9% of the sample were male. Presence of a multi-drug resistant organism was documented for 10.3% of the patients. There were 363 HAIs present in 273 patients. The prevalence of patients with a HAI was 9.9% (95%CI: 8.8-11.0). Hospital prevalence rates ranged from 5.7% (95%CI:2.9-11.0) to 17.0% (95%CI:10.7-26.1). The most common HAIs were surgical site infection, pneumonia and urinary tract infection, comprising 64% of all HAIs identified.
This is the first HAI PPS to be conducted in Australia in 34 years. The prevalence rate is higher than the previous Australian study and that reported by the ECDC, however differences in methodology limit comparison. Regular, large scale HAI PPS should be undertaken to generate national HAI data to inform and drive national interventions.
澳大利亚没有全国性的医疗保健相关感染（HAI）监测计划。仅在 1984 年进行过一项 HAI 点患病率研究。本研究的目的是估计澳大利亚急性成年住院患者中医疗保健相关感染（HAI）的负担。
在一组大型急性护理医院中进行了横断面点患病率研究（PPS）。所有数据均由两名经过培训的研究助理收集。监测方法基于欧洲疾病预防控制中心（ECDC）PPS 方案，采样方法有所不同，仅包括年龄≥18 岁的急性住院患者。应用 ECDC HAI 定义。
数据于 2018 年 8 月至 11 月收集。共纳入来自 19 家医院的 2767 名患者。患者的中位年龄为 67 岁，样本中 52.9%为男性。记录了 10.3%的患者存在多药耐药菌。在 273 名患者中存在 363 例 HAI。HAI 患者的患病率为 9.9%（95%CI：8.8-11.0）。医院患病率范围为 5.7%（95%CI：2.9-11.0）至 17.0%（95%CI：10.7-26.1）。最常见的 HAI 是手术部位感染、肺炎和尿路感染，占所有确定的 HAI 的 64%。
这是澳大利亚 34 年来首次进行 HAI PPS。患病率高于之前的澳大利亚研究和 ECDC 报告的患病率，但方法学的差异限制了比较。应定期进行大规模的 HAI PPS，以生成全国性的 HAI 数据，为国家干预措施提供信息和动力。
