Abstract
Objective: According to the importance of evaluating the antimicrobial resistance pattern in the management of nosocomial infections (NIs), we decided to investigate the prevalence of antimicrobial resistance in Chamran Heart Hospital.
Methods: This retrospective cross-sectional observational study was performed for 6 months from February to July 2022 at Shahid Chamran Hospital of Isfahan, Iran. All hospitalized patients with any NIs were eligible for the study. Clinical specimens were obtained from patients with NIs. All specimens underwent microbial culture, and if bacterial growth developed, differential tests were performed. Antibiotic susceptibility testing also was performed per the standards of Clinical and Laboratory Standards Institute, 2022.
Findings: Out of 201 examined samples, urinary infection (34.83%), pneumonia (27.86%), and sepsis (13.43%) were reported to be the most prevalent infections. Among Gram-negatives (76.12%), Citrobacter spp. (26.37%), Escherichia coli (24.87%), and Klebsiella spp. (11.44%) were the most common pathogens. About 54.9% of Citrobacter spp., 33.3% of E. coli, and 45.45% of Klebsiella spp. were resistant to carbapenems. About 1.88% and 15% of Citrobacter spp. were identified as pan-drug-resistant bacteria and extensively drug-resistant (XDR), respectively. In addition, 4.34% of Klebsiella spp. were identified as XDR. Among Gram-positives (23.88%), Enterococcus spp. (8.95%) was identified as the most common pathogen, and the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) was 11.11% and 61.11%, respectively.
Conclusion: In our study, carbapenem-resistant Enterobacteriaceae accounts for about 50% of all NIs. Moreover, despite the low prevalence of MRSA, VRE was reported to be high in our center when compared with other studies.
期刊介绍：
The main focus of the journal will be on evidence-based drug-related medical researches (with clinical pharmacists’ intervention or documentation), particularly in the Eastern Mediterranean region. However, a wide range of closely related issues will be also covered. These will include clinical studies in the field of pharmaceutical care, reporting adverse drug reactions and human medical toxicology, pharmaco-epidemiology and toxico-epidemiology (poisoning epidemiology), social aspects of pharmacy practice, pharmacy education and economic evaluations of treatment protocols (e.g. cost-effectiveness studies). Local reports of medication utilization studies at hospital or pharmacy levels will only be considered for peer-review process only if they have a new and useful message for the international pharmacy practice professionals and readers.
