| P. aeruginosa from Hospital-acquired pneumonia at Da Nang C Hospital in 2022 (cross-sectional study) | P. aeruginosa accounted for 32.58% cases of HAP, and showed resistance against all of tested antibiotics: tobramycin (34.78%), gentamycin (34.62%), ciprofloxacin (50%), levofloxacin (57.69%), imipenem (48.15%), meropenem (44%), cefepime (44.44%) and ceftazidime (44%). Piperacillin/tazobactam and amikacin maintained their efficacy with the resistance rate as low as 10.35% and 15.38%, respectively. | Hoa et al. (2023) [28] |
| P. aeruginosa from exacerbaction of chronic obstructive pulmonary disease at Kien Giang Province General Hospital in 2021 (retrospective cross-sectional study) | P. aeruginosa was responsible for 17.39% of infection cases. These strains resisted against imipenem (28.57%), meropenem (21.43%), ciprofloxacin (29%), piperacillin/tazobactam (21.43%), amikacin (21.43%) | Linh et al. (2021) [29] |
| P. aeruginosa from Hospital-acquired infection at Nguyen Tri Phuong Hospital from 2019–2021 (retrospective cross-sectional study) | P. aeruginosa has shown complete resistance to co-trimexazole. Although the average sensitivity rate of these bacteria to commonly used antipseudomonal antibiotics such as beta-lactams and aminoglycosides remains above 50%, meropenem exhibits a lower sensitivity rate compared to antibiotics in the same group, such as imipenem (42.0% versus 54.3%). The quinolone group has sensitivity rates below 50%. | Ha et al. (2023) [30] |
| P. aeruginosa from lower respiratory tract infection at Cho Ray Hospital 2021 (retrospective cross-sectional study) | P. aeruginosa was isolated at a rate of 13.9%, exhibited the highest resistant to ticarcillin/clavilanic acid (78%) and carbapenem group (68%–70%), colistin resistant rate was 2%. | Phu et al. (2022) [31] |
| P. aeruginosa isolated at the 108 Military Central Hospital from 2020–2022 (cross-sectional study) | P. aeruginosa are highly resistant to fluoroquinolones (62.8%) and aminoglycosides (53.4%). Among the multidrug-resistant (MDR) strains, 54.3% were also resistant to carbapenem (CPR), with the highest proportion found in the department of infectious diseases (65.52%), ICU (64.39%) and the Internal respiratory department (45.69%). In the CPR strains, 11.2% of isolates were found to be resistant to colistin, while 26.6% and 33.3% of these strains remained susceptible to amikacin and piperacillin/tazobactam, respectively. | Trang et al.(2022) [32] |
| P. aeruginosa from Hospital-acquired infection at Binh Dan Hospital from 2018–2020 (cross-sectional study) | P. aeruginosa was isolated from 11.16% of patients and was found to resistant to more than 50% of most used antibiotics | Ngan & Phuong (2022) [33] |
