OBJECTIVE:To provide reference for standardizing chemotherapy drug use in tumor patients,and to investigate the points of pharmaceutical care. METHODS:2 242 medical records of tumor chemotherapy were sampled from 4 third grade class A hospitals to investigate chemotherapy drug plan and pharmaceutical care. The reasons for irrational drug use were analyzed, and the points of pharmaceutical care were summarized. RESULTS:There were 1 295 cases of irrational chemotherapy drug use, among which irrational dose accounted for 26.87%;irrational antiemetic drugs use 14.44%;irrational chemotherapy plan 13.13%;irrational drug selection 10.89%;irrational dosing order 10.04%. 6 items of rational chemotherapy drug use monitoring index were summarized,which were rationality of scheme selection,drug selection,drug dose,dosing time and order,solvent concentration, route of administration,adjuvant drug use;covering the process of chemotherapy. CONCLUSIONS:Pharmaceutical care can be standardized through rationality investigation on chemotherapy drug use of tumor patients,which contributes to improving pharma-ceutical care level of clinical pharmacists,and rational drug use the clinic.
