Objective To analyze the use of carbapenems in a hospital in 2016, so as to provide evidence for rational use of antibiotics. Methods The medical records of all patients treated with carbapenems in 2016 were collected. The use of antimicrobial agents, types of infections and etiological examinations were investigated. The medication rationality of antibiotics was evaluated, and the inappropriate problems were classified. Results A total of 383 cases were extracted, including 137 (35.78%) females and 246 (64.22%) males, with an average age of (59±12) years and a median age of 61 years. The total inspection rate was 95.30% (365/383). A total of 258 cases (67.36%) received the medicine according to the drug sensitivity results. The drug utilization indexes of imipenem/cilastatin sodium and biapenem were 1.29 and 0.76, respectively. There were 60 cases (15.67%) of irrational use of carbapenems. Conclusion There is still unreasonable clinical use of carbapenems in the hospital in 2016. The rationality evaluation of carbapenems use is conducive to understanding the clinical use and finding the typical problems, so as to provide reference for rational drug intervention.
