This study investigated the changes in antibiotic consumption and antimicrobial resistance rates after restricting piperacillin/tazobactam. The results showed a significant decrease in the consumption of piperacillin/tazobactam after implementing the restriction policy. Additionally, the resistance rates of Acinetobacter spp. and other bacteria decreased significantly, indicating a positive impact of piperacillin/tazobactam restriction on controlling bacterial resistance.
The increasing resistance of gram-negative bacteria is a serious global public health concern. One way to prevent increasing antibiotic resistance is by implementing the antibiotic stewardship program. This study aimed to assess the changes in the consumption of antimicrobials and antimicrobial resistance rates after implementing piperacillin/tazobactam restriction. This study was conducted at Kandong Sacred Heart Hospital. We retrospectively collected and analysed data between October 2018 and May 2021 to evaluate antibiotic consumption and resistance patterns after restricting piperacillin/tazobactam. This study included two periods, a 16-month pre-restriction period and a 16-month post-restriction period. During the study period, there was a significant decrease in the consumption of piperacillin/tazobactam after implementing the restriction policy (127.82 +/- 9.39 to 104.82 +/- 15.66 defined daily doses/1000 patient days, p < 0.001). A significant decrease in the resistance rate of Acinetobacter spp. was observed for cefepime (p = 0.001), ceftazidime (p = 0.004), levofloxacin (p = 0.021), meropenem (p = 0.002) and piperacillin (p = 0.028). The introduction of piperacillin/tazobactam restriction reduced their use and positively impacted the resistance rates of Acinetobacter spp., carbapenem-resistant Pseudomonas spp. and carbapenem-resistant Enterobacteriaceae which are major threats to nosocomial infections.
