Nowadays, the resistance to available antibiotics could be mentioned as a global threat to public health. The aim of this preliminary study was to conduct a retrospective survey associated with the prevalence of Nosocomial Infections (NIs) and the pattern of microbial resistance in a tertiary care referral hospital (Alzahra), Isfahan, Iran. The data between the years 2016 to 2022 were extracted from the official database of hospital NI records. The microbiological culture results, represented by non-repetitive specimens, were further analyzed for pathogens and the pattern of antibiotic resistance. Then antibiotic susceptibility testing was done using standard methods of disk diffusion or Phoenix M50. The recorded variables have been presented as mean ± standard deviation, prevalence, and percentage. Data were analyzed using SPSS version 20. For a duration of 5.5 years, the period prevalence of NIs was recorded as 2%, with more than 50% associated with ventilator-associated events and urinary tract infections. Klebsiella pneumonia, Acinetobacter baumannii, and Staphylococcus were the main pathogens. Further study of specimens from the year 2022 (n= 898) confirmed the most isolated bacteria as Klebsiella pneumonia (n = 290, 32%), Acinetobacter baumannii (n= 206, 23%), Enterococcus (faecium-fecalis n=125, 14%), Escherichia coli (n = 116, 13%), Staphylococcus aureus (n = 95, 11%), and Pseudomonas aeruginosa (n = 66, 7%). Resistance (R%) in Isfahan versus the whole country was confirmed for Klebsiella pneumonia (third or fourth generation of cephalosporins: R = 80.9 vs. 82%), fluoroquinolones (R = 76.6 vs. 73%), beta-lactamase inhibitors (R = 75 vs. 79%), carbapenems (R = 65.7 vs. 66%), and so on, respectively. There has been reported an increase in the proportion of isolates resistant to cephalosporins, fluoroquinolones, and others. The variety of latent pathogens resistant to frequently administered antibiotics highlights the significance of continued and homogenous antimicrobial evidence-based pharmacotherapy investigations in Isfahan, Iran. Further studies in this direction are recommended.
如今,对现有抗生素的耐药性可谓是对公共卫生的全球性威胁。本初步研究旨在对伊朗伊斯法罕市一家三级转诊医院(Alzahra)的非医院感染(NIs)流行率和微生物耐药性模式进行回顾性调查。以非重复标本为代表的微生物培养结果进一步分析了病原体和抗生素耐药性模式。然后使用标准的磁盘扩散法或凤凰 M50 法进行抗生素药敏试验。记录的变量以均数±标准差、流行率和百分比表示。在 5.5 年的病程中,NIs 的流行率为 2%,其中 50%以上与呼吸机相关事件和泌尿道感染有关。肺炎克雷伯菌、鲍曼不动杆菌和葡萄球菌是主要病原体。对 2022 年标本(n= 898)的进一步研究证实,分离出的最多细菌为肺炎克雷伯菌(n= 290,32%)、鲍曼不动杆菌(n= 206,23%)、肠球菌(粪-粪球菌 n=125,14%)、大肠埃希菌(n=116,13%)、金黄色葡萄球菌(n=95,11%)和绿脓杆菌(n=66,7%)。伊斯法罕与全国相比,肺炎克雷伯菌(第三代或第四代头孢菌素:R = 80.9 vs. 82%)、氟喹诺酮类(R = 76.6 vs. 73%)、β-内酰胺酶抑制剂(R = 75 vs. 79%)、碳青霉烯类(R = 65.7 vs.66据报道,对头孢菌素类、氟喹诺酮类和其他药物耐药的分离菌比例有所增加。对常用抗生素耐药的潜伏病原体种类繁多,这凸显了在伊朗伊斯法罕持续开展同质抗菌循证药物治疗调查的重要性。建议在这方面开展进一步研究。
