某市50所二级及以上医院连续6年医院感染监测指标调查

Monitoring indexes of healthcare-associated infection in 50 secondary or higher grade hospitals in a city for consecutive 6 years

摘要:

目的 了解某市50所二级及以上医院2017—2022年连续6年医院感染监测指标变化趋势。 方法 连续6年收集该市50所二级及以上医院医院感染监测指标, 比较医院感染监测指标变化趋势。 结果 医院感染管理专职人员数量由2017年的91人增加至2022年的165人; 医院感染信息化使用率由2017年的17.00%上升至2022年的54.00%。2017—2022年连续6年50所二级及以上医院医院感染发病率(0.91% VS 0.59%)、医院感染现患率(2.36% VS 1.08%)、Ⅰ类切口手术部位感染率(0.33% VS 0.16%)均呈下降趋势, 医务人员手卫生依从率呈上升趋势(61.03% VS 85.04%)。血管导管相关血流感染、呼吸机相关肺炎、导尿管相关尿路感染发病率整体均呈现下降趋势。三级医院的医院感染发病率、医院感染现患率、医务人员手卫生依从率、呼吸机相关肺炎发病率均高于二级医院, 二级医院的Ⅰ类切口手术部位感染率高于三级医院, 差异均有统计学意义(均P＜0.001)。 结论 规范开展医院感染监测, 根据监测结果完善医院感染防控制度及措施, 能降低医院感染发病率。

Abstract:

Objective To understand the changing trend of healthcare-associated infection (HAI) monitoring indexes in 50 secondary and higher grade hospitals in a city for 6 consecutive years from 2017 to 2022. Methods Infection monitoring indexes from 50 secondary or higher grade hospitals in the city for 6 consecutive years were collec-ted, and changing trend of HAI monitoring indexes were compared. Results The number of full-time HAI management professionals increased from 91 in 2017 to 165 in 2022. The utilization rate of HAI information system increased from 17.00% in 2017 to 54.00% in 2022. In 6 consecutive years from 2017 to 2022, the incidence of HAI (0.91% vs 0.59%), prevalence rate of HAI (2.36% vs 1.08%), infection rate of class Ⅰ incision surgical site infection (0.33% vs 0.16%) in 50 secondary or higher grade hospitals all showed downward trends, while health care workers' hand hygiene compliance rate showed an upward trend (61.03% vs 85.04%). Incidences of vascular cathe- ter-related bloodstream infection, ventilator-associated pneumonia, and catheter-associated urinary tract infection all showed downward trends. Incidence of HAI, prevalence rate of HAI, health care workers' hand hygiene compliance rate, and incidence of ventilator-associated pneumonia in tertiary hospitals were all higher than those in secon-dary hospitals, while surgical site infection rate of class Ⅰ incision in secondary hospitals was higher than that in tertiary hospitals, with statistically significant differences (all P < 0.001). Conclusion Standardizing the monitoring of HAI, as well as improving the prevention and control system and measures of HAI according to the monitoring results can reduce the incidence of HAI.
