Abstract

Carbapenem administration is an important therapy for nosocomial infections due to MDRO, especially Acinetobacter baumannii. The global increase in carbapenem-resistant A. baumannii (CRAB) that causes this pathogen has significantly threatened public health due to the lack of adequate treatment options due to the very few currently available antimicrobial agents that actively fight CRAB. Antimicrobial resistance is a major negative impact of inappropriate antimicrobial prescribing. Ineffective empiric treatment (initial antibiotic regimen not sensitive to identified pathogens based on in vitro sensitivity test results) is associated with a higher rate of deaths compared to effective empiric treatment. In this study, we analyzed the correlation between the suitability of empiric and definitive antibiotics and the clinical outcomes of patients with bacteremia due to CRAB treated in the inpatient ward of Dr. Soetomo Tertiary Referral Hospital, Surabaya. There were 227 isolates of bacteremia due to CRAB, consisting of 156 carbapenem-resistant A. baumanni and 71 carbapenem-sensitive A. baumannii. There were 88 isolates that met the inclusion and exclusion criteria, and all of them were resistant to ceftriaxone, cefepime, and ciprofloxacin. A total of 29.5% of the isolates were sensitive to cotrimoxazole, 3.4% of the isolates were sensitive to tigecycline, and 2.3% of the isolates were sensitive to amikacin, levofloxacin, and cefoperazone sulbactam. Adequate empirical antibiotics and definitive antibiotics (sensitive based on culture sensitivity test) amounted to 12.5% and 27.3%, respectively. There is no significant correlation between the suitability of empiric and definitive therapies with the patients' clinical outcomes (death and length of stay).
