Background:
Bloodstream infections (BSIs) are one of the most critical illnesses requiring intensive care unit (ICU) admission. This study assessed patterns of antimicrobial use and resistance in ICU patients with BSIs.
Methods:
Inpatients admitted to the ICU and who received at least one antimicrobial agent between January 1, 2017, and December 31, 2019, were included in the study. Electronic patients' medical records were used to collect patients' demographic, clinical, and microbiological data.
Results:
A total of 1051 patients were enrolled in the study, where 650 patients (61.84%) were treated with three or more antimicrobial agents. The most frequently used antimicrobials were piperacillin/tazobactam followed by teicoplanin, meropenem, and levofloxacin. The most predominant multidrug-resistant pathogens were Acinetobacter baumannii, followed by Escherichia coli, Methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumonia, and Pseudomonas aeruginosa.
Conclusions:
The administration of the antimicrobials among ICU patients was highly based on a combination of three or more broad-spectrum agents. MDR pathogens were found to be highly prevalent among ICU patients with BSI. Therefore, we suggest recommending that hospital policies should apply the antimicrobial stewardship protocols, infection control, and implement antimicrobial de-escalation protocol to reduce the harm pressure of antimicrobial resistance.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
