Abstract:
Background:We compared the antimicrobial resistance rates (AMRs) of major glucose nonfermenting gram-negative bacilli, Acinetobacter baumannii and Pseudomonas aeruginosa, under different clinical conditions. The purpose of the study was to provide useful background data to set up infection control strategies for infection-vulnerable patients.
Methods:The AMRs of blood isolates were compared in various clinical conditions, using data from the Antimicrobial Resistance Surveillance System in Korea.
Results:A. baumannii blood isolates from patients with healthcare-associated infections, inpatients, or intensive care unit (ICU)-admitted patients consistently exhibited higher AMRs to most antimicrobials, except minocycline, tigecycline, and colistin, compared with those from patients with community-acquired infections, outpatients, or non-ICU-admitted patients, respectively. P. aeruginosa blood isolates from patients with healthcare-associated infections showed higher AMRs to most antimicrobials, except ceftazidime and aztreonam, compared with those from patients with community-acquired infections, but not compared to those from inpatients or ICU-admitted patients.
Conclusion:Higher AMRs were associated with A. baumannii bloodstream infections under various clinical conditions, such as healthcare-associated infections and infections in inpatients and ICU-admitted patients. Considering the high AMRs and the limited number of treatment options of A. baumannii, vigorous efforts should be used to prevent the spreading of A. baumannii infections in patients with vulnerable conditions.
