山东省新型冠状病毒肺炎某定点医院感染事件的疾控视角分析

  目的   从疾控视角对山东省新型冠状病毒肺炎（COVID-19）某定点医院感染事件进行回顾分析，以有效预防医院感染暴发。  方法   查阅事件发生医院记录、回访相关人员进行流行病学调查。  结果   强化定点医院感染控制管理；明确COVID-19疫情期间定点医院专收COVID-19患者，不再收治其他疾病患者；对所有医院留观室、呼吸科住院患者及其陪护人员每7 d检测1次新型冠状病毒核酸，患者出院及其陪护人员结束1次陪护时，再进行1次核酸检测。  结论   认真落实“各项医院感染控制措施，扩大核酸检测范围、加密核酸检测频次”的策略；加强督导、整改，确保医疗安全。

Analysis on a nosocomial infection event in a designated COVID-19 hospital in Shandong from the perspective of disease control

  Objective  To analyze a nosocomial infection event in a designated hospital of coronavirus disease 2019 (COVID-19) in Shandong province retrospectively from the perspective of disease control and provide evidence to prevent the incidence of similar event.   Methods  The epidemiological investigation was carried out by analyzing the medical records of the hospital where the nosocomial infection occurred and interviewing the relevant personnel.   Results  Infection control and management in the designated hospitals were strengthened, and only patients with COVID-19 could be admitted to the designated hospital during the epidemic period rather than the patients with other diseases. The nucleic acid test was performed every 7 days for all the inpatients and their accompanying persons in the observation room and respiratory department of the hospital. Once the patients were discharged from the hospital and their accompanying persons finished nursing, nucleic acid test was performed for them again.   Conclusion  The strategy of “implementing all the nosocomial infection control measures, expanding the coverage of nucleic acid test and increasing the frequency of encrypted nucleic acid detection” should be continued; and the supervision and improvement should be enhanced to ensure medical safety.
