Epidemiological and Clinical Insights into : A Six-Year Study on Age, Antibiotics, and Specimens.

BACKGROUND

This six-year retrospective study provides an in-depth analysis of the epidemiological and clinical patterns associated with () infections, focusing on age distribution, antibiotic resistance profiles, and specimen types.

AIM

The research examines the incidence and characteristics of non-Multi-Drug Resistant (non-MDR) and Multi-Drug Resistant (MDR) strains by reviewing patient records from January 2016 to December 2022.

METHODS

Through a statistical analysis, the study highlights the incidence rates across diverse age groups and explores the impact of antibiotic treatment regimens on infection outcomes. Additionally, it identifies the primary clinical specimen types for each strain, noting an association between non-MDR and midstream urine samples, while MDR strains were more frequently found in respiratory, wound, peripheral, and central line swaps/specimens.

RESULTS

The results indicate that in 2016, non-MDR infections were notably more frequent compared to MDR cases. However, a significant shift occurred in 2021 and 2022, with a marked decrease in non-MDR cases and an increase in MDR infections. Antibiotic susceptibility testing revealed that non-MDR strains were commonly tested against cefazolin, ceftazidime, ciprofloxacin, gentamicin, nitrofurantoin, oxacillin, piperacillin/tazobactam, and trimethoprim/sulfamethoxazole. In contrast, MDR strains were frequently tested against amikacin, cefepime, colistin, meropenem, imipenem, and tigecycline.

CONCLUSION

This study enhances the understanding of clinical behaviour and resistance patterns, offering valuable insights to support future research and inform strategies for infectious disease management and control.
