Application of disinfection in infection prevention and control at centers for disease control and prevention
消毒工作在疾控中心感染预防控制中的应用

摘要

目的 探讨消毒工作在疾病预防控制中心感染预防控制中的具体应用效果，为提升疾控机构感染管理水平提供科学依据。方法 选取2024年1月1日至2024年12月31日期间在阜新市疾病预防控制中心实施的消毒管理措施进行回顾性研究。纳入对象为该中心工作人员与来访者，分为实施前（对照组，n=150）和实施后（干预组，n=160）两组。干预组严格执行环境表面、空气、手卫生及器械消毒等综合管理措施。比较两组空气细菌总数、物体表面细菌培养合格率、手卫生依从性等指标。采用SPSS 26.0统计软件分析，计量资料以均数±标准差表示，组间比较用t检验，计数资料用χ²检验。结果 干预组空气细菌总数显著低于对照组（42.7±8.3 CFU/m³ vs. 89.5±10.6 CFU/m³，P<0.001），物体表面细菌培养合格率明显提高（97.5% vs. 82.0%，P=0.003），手卫生依从性从66.7%提升至92.3%（P=0.002）。结论 规范化的消毒措施在疾控中心感染预防控制中具有显著效果，能有效降低病原微生物污染与感染风险，建议在各级疾控机构广泛推广应用。

Abstract

Objective To evaluate the application of disinfection in infection prevention and control at a CDC, providing evidence for improving infection management.
Methods A retrospective study was conducted on disinfection measures implemented at Fuxin CDC from January to December 2024. Participants included staff and visitors, divided into a control group (n=150) and an intervention group (n=160). The intervention group implemented standardized measures for surface, air, hand hygiene, and equipment disinfection. Indicators compared included airborne bacterial counts, surface culture qualification rates, and hand hygiene compliance. Statistical analysis was performed with SPSS 26.0.
Results Airborne bacterial counts were significantly lower in the intervention group (42.7±8.3 CFU/m³ vs. 89.5±10.6 CFU/m³, P<0.001). Surface qualification rates improved (97.5% vs. 82.0%, P=0.003), and hand hygiene compliance increased from 66.7% to 92.3% (P=0.002).
Conclusion   Standardized disinfection significantly reduces microbial contamination and infection risk in CDCs, and should be widely promoted in public health institutions.
