目的研究基层综合医院多重耐药菌(MDR0s)感染及临床分布现状,有针对性地采取防控措施。方法通过回顾性调查方法,对某基层综合医院2014年度住院患者送检的病原学标本检测结果进行调查与分析。结果该医院2014年度从住院患者送检病原学标本中共分离出病原菌2 305株,其中医院内感染患者分离出551株,含多重耐药菌(MDROs)184株,占分离菌株数的33.39%。社区获得感染患者分离出1 754株,含多重耐药菌328株,占分离菌株数的18.70%。有79.39%的病原菌分离自呼吸道标本。多重耐药菌感染患者主要分布在重症监护病房(ICU)、神经外科和产科。结论该医院感染患者分离出的病原菌中多重耐药菌占比较大,多见于呼吸道感染,感染患者主要分布在ICU,多重耐药菌感染应针对性防控。
Objective To study the status of multidrug-resistant bacteria (MDR0s) infection and clinical distribution in primary general hospitals and to take targeted prevention and control measures. Methods The retrospective investigation method was used to investigate and analyze the results of etiological examination of inpatients in a grassroots general hospital in 2014. Results A total of 2 305 pathogens were isolated from hospitalized patients in 2014, of which 551 isolates and 184 multi-drug resistant isolates (MDRs) accounted for 33.39% of the isolates. There were 1 754 isolates and 328 multidrug-resistant isolates in community-acquired infections, accounting for 18.70% of the isolates. 79.39% of pathogens were isolated from respiratory specimens. Patients with multiple drug-resistant infections are mainly found in intensive care units (ICUs), neurosurgery and obstetrics. Conclusion The multidrug-resistant bacteria isolated from patients with nosocomial infection accounted for a large proportion of multi-resistant bacteria, more common in respiratory infections, the main infection in patients with ICU, multi-drug resistant infections should be targeted prevention and control.
