Objective To evaluate the economic effects of different dosage regimens of imipenem against hospital common drug-resistant bacteria blood infection. Methods A total of 151 cases using imipenem against hospital common drug-resistant bacteria blood infection were investigated in Zhongshan City People's Hospital from 2019 to 2020 were divided into 5 groups according to actual dosage regimens. group A (0.5 g, q12h), group B (0.5 g, q8h), group C (1 g, q12h), group D (1 g, q8h) and group E (1 g, q6h). These dosage regimens were evaluated with Monte Carlo simulation (MCS), caluated for cumulative fraction responses (CFR), and conducted cost-effectiveness analysis (CEA) respectively. Results the C/E values of the 5 groups were 68.5, 68.2, 100.4, 82.6 and 93.1 respectively. Taking A regimen as the reference, the incremental cost effectiveness ratio(∆C/∆E) of other 4 regimens were 65.9, 845.1, 147.2, and 201.8 respectively. Conclusion Regimen B with the least C/E value had poor antibacterial activity against multi-drug resistant Acinetobacter baumannii (MDR-AB), carbapenem resistant Pseudomonas aeruginosa (CRPA) and carbapenem resistant enterobacteriaceae (CRE), which is not the best regimen for the hospital common drug-resistant bacteria blood infection. Dosage regimen should be selected combinating with clinical drug resistant strains. Regimen D is more effective than regimen C and regimen E, and regimen E with more administration frequency does not show higher benefit.
