Özet

The purpose of this study was to investigate the factors that required dose adjustments

of antimicrobial drugs in intensive care unit (ICU) patients and to identify

the drugs that required the most dose adjustments. The current prospective study

was conducted in the reanimation ICU with 26-bed capacity of a university-affiliated

hospital from September to December 2022. Two clinical pharmacists

on duty examined patients’ antimicrobial drug dosages daily. The acceptance

status of the recommendations and the patients’ demographic information were

recorded. The study involved 133 ICU patients, and antimicrobial drug recommendations

were made for 48 patients, 31 (64.6%) of whom were male. The

median (IQR) age of the 48 patients was 67 (54–77). The count of recommendations

was 94, and the acceptance rate was 100%. The recommendation rates

were as follows: 71.3% for renal function, 11.7% for presence of continuous

renal replacement therapy, 10.6% for indication, 4.3% for body weight, and 2.1%

for loading dose. The top 3 drugs for which recommendations were made the

most were colistin (21.3%), meropenem (18.1%), and piperacillin-tazobactam

(12.8%). The most troublesome drug was colistin, which is frequently used to

treat Acinetobacter pneumonia. Clinical pharmacist and physician collaboration

may help rationalize ICU antimicrobial drug use.
