Evaluation of Prevalence and Microbial Resistance Pattern in Patients with Nosocomial Infections in Razi Ghaemshahr Hospital, Mazandaran

Abstract

Background and purpose: Hospital infections remain a significant health concern despite advancements in treatment methods. The emergence and spread of pathogens with multiple resistance remain a global health issue. The purpose of this study was to investigate the prevalence of nosocomial infections and determine the antibiotic resistance pattern in Razi Ghaemshahr Hospital, Mazandaran. Materials and methods: This descriptive cross-sectional study was carried out at Razi Ghaemshahr Hospital in Mazandaran province during 2016-2017. Positive cultures from hospitalized patients were used as samples and subjected to antibiotic resistance pattern analysis using the disk diffusion method. Results: Out of the 672 hospitalized patients in different wards, the infectious ward had the highest frequency distribution of patients (40%). The most commonly isolated pathogens were Escherichia coli (26.2%), Acinetobacter baumannii (14.7%), Enterobacter (14.1%), Pseudomonas aeroginosa (13.5%), and Citrobacter (12.8%). The pathogens were highly resistant to cephalosporins, fluoroquinolones, beta-lactamase inhibitors, and carbapenems. Conclusion: It was found that the most frequently isolated pathogen was Escherichia coli. The emergence of Citrobacter with high antibiotic resistance can possibly be attributed to a shift in the prevalence pattern of microorganisms within this hospital
