Objective: In Vietnam, antibiotic resistance has been gained the attention of medical professionals in antibiotic use management. This study aimed to investigate the antibiotic resistance among hospital-acquired infections at Buu Dien General Hospital in Ho Chi Minh City in the period of 01-12/2017.

Methods: This cross-sectional descriptive study was conducted on the retrospective data of all antibiograms of bacteria isolated from hospital-acquired infections at Buu Dien General Hospital in Ho Chi Minh City in the period of 01-12/2017 to investigate the antibiotic resistance. Characteristics of antibiotic resistance were described by frequency and percentage of types of bacteria isolated and antibiotics being resistant.

Results: A total of 179 isolates were collected during the period 01-12/2017, of which E. coli was the most commonly isolated pathogen (41.3%). The highest prevalent infections were in the skin and mucosa; respiratory tract; and urinary tract (34.6%; 32.4%; and 27.9%). The antibiotic susceptibility testing used 21 types of antibiotics. Among them, S. aureus was 82% resistant to clindamycin and 75% resistant to cefuroxime; the Proteus resistance percentages to amoxicillin/clavulanic, second-generation cephalosporins, ciprofloxacin and fosfomycin varied from 50 to 93%; Pseudomonas was 92% resistant to fosfomycin and 62% resistant to ceftazidime; A. baumannii was resistant to most classes of agents used (50-75%). Both E. coli and Klebsiella were highly resistant to gentamicin, amoxicillin, ciprofloxacin, 2nd and 3rd generation cephalosporin’s. Polymyxin B-resistant Proteus cultures were detected at 67%.

Conclusion: The study described the antibiotic resistance situation of hospital-acquired bacteria at the Buu Dien General Hospital from 01-12/2017. This information will aid physicians to select proper antibiotics for their patients in the next period.
