目的了解医院住院患者的医院感染现状、多重耐药菌分布、抗菌药物使用及病原学标本送检等指标情况,为制定防控措施提供依据。方法采用横断面调查方法,对某医院住院患者医院感染现患率等指标进行调查。结果调查当日实查住院患者1 471例,发生医院内获得感染39例、42例次,感染现患率为2.65%、例次感染率为2.86%。感染现患率较高的有神经外科和胃肠外科等科室,感染部位均以下呼吸道为主。感染病原菌以革兰阴性菌为主,其中多重耐药菌株占检出菌总数的48.48%。调查日抗菌药物使用率为42.01%,住院患者标本送检率为21.20%。结论该院医院感染率尚在规定范围,标本送检和耐药菌监测应作为重点防控措施。
Objective To understand the status of nosocomial inpatients with nosocomial infections, the distribution of multidrug-resistant bacteria, the use of antimicrobial agents and the detection of etiological specimens for the purpose of providing evidence for prevention and control measures. Methods A cross-sectional survey method was used to investigate the prevalence of nosocomial infections such as inpatients in a hospital. Results On the day of investigation, 1 471 inpatients were investigated. There were 39 cases and 42 cases of hospital-acquired infections. The prevalence rate of infection was 2.65% and the infection rate was 2.86%. Infection with a higher prevalence of neurosurgery and gastroenterology departments, the site of infection are mainly the following respiratory tract. Gram-negative bacteria were the main pathogens of infection, of which 48.48% were multi-resistant strains. On the survey day, the usage rate of antibacterials was 42.01% and the rate of inpatients was 21.20%. Conclusion The prevalence of nosocomial infection in this hospital is still within the prescribed range. The submission of specimens and the monitoring of drug-resistant bacteria should be taken as the key prevention and control measures.
