Abstract
Objective : Investigational drugs are often considered to be high-risk or hazardous medications. It is necessary to study medication errors in clinical trials. This study aimed at identifying the frequency and types of prescribing errors in oncology clinical trials.
Methods : We retrospectively analyzed investigational drug orders and pharmacist intervention records from December 2015 to February 2017 in the National Cancer Center.
Results : Among 12,387 investigational drug orders, 673 (5.43%) prescribing errors were detected by pharmacists.
Regarding the route of administration, the prescription error rate related to IV medications was higher than that of oral medications (7.23% vs. 4.34%). The most common prescribing error in IV medications were wrong medication kit number (164 cases, 48.52 %) followed by incorrect diluent (75 cases, 22.19%), wrong dose (70 cases, 20.71%), and omission of information (20 cases, 5.92%). Meanwhile, the most common prescribing error in oral medications were wrong medication kit number (119 cases, 35.52 %) followed by incorrect quantity (67 cases, 20.0%), wrong dose (58 cases, 17.31%), and incorrect treatment duration (45 cases, 13.43%).
Conclusions : This study provides the frequency and types of prescribing errors in oncology clinical trials. The pharmacist intervention may improve safety of investigational drug use.
