目的 分析滁州地区医院感染病原菌分布与耐药特点。方法 通过滁州市第一人民医院、滁州市儿童医院医院感染实时监控系统智能识别并实时上报2022年住院患者医院感染病例1152例次，进行细菌鉴定及药敏试验。结果 1152例次医院感染主要感染类型为下呼吸道感染(44。10％)、泌尿系统感染(18。75％)、血流感染(13。72％);共分离出病原菌1116株，其中革兰阴性菌占52。15％，检出率较高的是鲍曼不动杆菌(6。63％)、肺炎克雷伯菌(6。81％)、大肠埃希菌(7。71％)和铜绿假单胞菌(6。27％);革兰阳性菌占22。22％，检出率较高的是金黄色葡萄球菌(2。51％);真菌占25。63％，主要为假丝酵母(15。59％)。特殊耐药菌产超广谱β-内酰胺酶(ESBL)大肠埃希菌检出率51。16％、ESBL肺炎克雷伯菌检出率21。05％，耐甲氧西林金黄色葡萄球菌检出率28。57％。鲍曼不动杆菌对各种抗菌药物耐药率均超过50％;肺炎克雷伯菌对氨苄西林耐药率最高(100％)，对氨苄西林/舒巴坦、头孢唑林、头孢呋辛耐药率均超过60％，对亚胺培南(34。21％)、妥布霉素(31。58％)、左氧氟沙星(10。53％)耐药率降低。大肠埃希菌对氨苄西林耐药率最高(90。70％)，对呋喃妥因(4。65％)、亚胺培南(2。33％)、头孢替坦(2。33％)耐药率较低。铜绿假单胞菌对环丙沙星(2。86％)、庆大霉素(2。86％)、妥布霉素(2。86％)和左氧氟沙星(2。86％)耐药率最低。结论 滁州地区医院感染细菌构成比主要以鲍曼不动杆菌、大肠埃希菌等为主，细菌耐药率较高。
Analysis of Bacterial Monitoring and Drug Sensitivity Test Results for Hospital Infections in Chuzhou
Objective To analyze the distribution and drug resistance characteristics of hospital infection pathogens in Chuzhou.Method By using the real-time infection monitoring system of Chuzhou First People's Hospital and Chuzhou Children's Hospital,1152 hospital-ized cases of hospital infection in 2022 were intelligently identified and reported in real-time,and bacterial identification and drug sensi-tivity tests were conducted.Result The main types of hospital infections in 1152 cases were lower respiratory tract infections(44.10％),urinary system infections(18.75％),and bloodstream infections(13.72％);A total of 1116 strains of pathogenic bacteria were isolated,with Gram-negative bacteria accounting for 52.15％.The highest detection rates were Acinetobacter baumanii(6.63％),Klebsiella pneu-moniae(6.81％),Escherichia coli(7.71％),and Pseudomonas aeruginosa(6.27％);Gram-positive bacteria accounted for 22.22％,with Staphylococcus aureus(2.51％)having a higher detection rate;Fungi accounted for 25.63％,mainly Candida(15.59％).Extrabroad-spectrum production of special drug-resistant bacteria β-The detection rate of Escherichia coli,Klebsiella pneumoniae,and methicillin-resistant Staphylococcus aureus was 51.16％,21.05％,and 28.57％,respectively.The resistance rate of Acinetobacter baumanii to various antibacterial drugs exceeds 50％;Klebsiella pneumoniae has the highest resistance rate to ampicillin(100％),with resistance rates ex-ceeding 60％to ampicillin/sulbactam,cefazolin,and cefuroxime.The resistance rates to imipenem(34.21％),tobramycin(31.58％),and levofloxacin(10.53％)decrease.Escherichia coli has the highest resistance rate to ampicillin(90.70％),while it has a lower resistance rate to furantoin(4.65％),imipenem(2.33％),and cefotetan(2.33％).Pseudomonas aeruginosa has the lowest resistance rates to cipro-floxacin(2.86％),gentamicin(2.86％),tobramycin(2.86％),and levofloxacin(2.86％).Conclusion The bacterial composition of hospi-tal infections in Chuzhou is mainly composed of Acinetobacter baumanii,Escherichia coli,etc.,with a high bacterial resistance rate.
