目的了解医院感染基本情况,找出重点薄弱环节,为提高医院感染防控水平提供依据。方法采用回顾性调查和前瞻性研究方法,对某三级综合医院住院患者医院感染病例进行综合分析。结果 2年共调查住院患者103 117例,发现医院感染病例3 098例、3 456例次,医院感染发生率为3.00%、例次感染率为3.35%。以重症医学科住院患者医院感染率最高,例次感染率为31.33%。下呼吸道感染患者构成比占36.20%,居感染部位的首位,其次是上呼吸道感染和泌尿道感染。结论该医院住院患者医院感染率尚在规范指标之内,但感染重点部位和重点环节比较突出,应当有针对性地加强重点部位和高危人群防控措施。
Objective To understand the basic situation of nosocomial infection and find out the key weak points in order to provide basis for the prevention and control of nosocomial infections. Methods A retrospective survey and prospective study were conducted to analyze the prevalence of hospital-acquired inpatients in a tertiary general hospital. Results A total of 103 117 hospitalized patients were investigated in 2 years. There were 3 098 cases of hospital infection and 3 456 cases of hospital infection. The incidence of nosocomial infection was 3.00% and the incidence of nosocomial infection was 3.35%. Inpatients admitted to intensive care unit had the highest hospital infection rate, with a case-to-case infection rate of 31.33%. The proportion of patients with lower respiratory tract infection accounted for 36.20%, ranking first in infected parts, followed by upper respiratory tract infection and urinary tract infection. Conclusion The prevalence of nosocomial infection in hospital is still within the standard index, but the key parts and key links of infection are prominent. The prevention and control measures of key areas and high-risk groups should be strengthened in a targeted manner.
