Abstract: Objective To establish the drug utilization evaluation criteria for bevacizumab and promote the rational use of bevacizumab through appropriate pharmaceutical interventions. Methods The archived medical records of 100 inpatients using bevacizumab injection in the first half of 2022 and the second half of 2022 were retrospectively analyzed. According to the instructions of bevacizumab and relevant clinical guidelines, the evaluation criteria of bevacizumab drug utilization were formulated, and the weighted advantage and inferiority solution method (TOPSIS) was used to objectively evaluate the use of bevacizumab. According to the evaluation results, the possible reasons were analyzed, and then the corresponding pharmaceutical intervention measures were formulated and continuous intervention was given. Finally, the weighted TOPSIS method was used to evaluate the use of bevacizumab after intervention. Results Before pharmaceutical intervention, there were 17 reasonable prescriptions (17.00%), 0 basic reasonable prescriptions and 83 unreasonable prescriptions (83.00%). After the intervention, there were 55 reasonable prescriptions (55.00%), 24 basically reasonable prescriptions (24.00%) and 21 unreasonable prescriptions (21.00%), which was improved compared with that before the intervention. After pharmaceutical intervention, the previous chemotherapy regimen, medication sequence, indications and combination drugs were improved, and the differences were statistically significant (P<0.05). Conclusion The weighted TOPSIS method can objectively and comprehensively evaluate the use of bevacizumab, which is convenient to find problems and intervene in time and promote the reasonable use of drugs.
