Background : As medication errors can cause serious harm to patients, preventing and avoiding them is important. Recently, a series of medication errors associated with taking dexamethasone at the wrong frequency occurred in patients with multiple myeloma in St. Mary’s Hospital. To prevent medication errors, the pharmacy improved the overall process including medication preparation, labeling, patient education, and monitoring. This study aimed to evaluate the effectiveness of these changes and the need for additional action. Methods : The improvements included changing the educational materials, including labeling, and increasing the number of medication counseling sessions. Medication counseling was conducted three times. The first was before starting the medication, the second was 2~3 days after starting medication, and the third was at the end of the first cycle of treatment. Assessment of medication awareness (usage, drug information, 3 points each) and compliance (based on Morisky’s scale, 5 points) was done at each counseling session. Results : The mean age of the study population was 60.8 years. The mean score of medication usage awareness at the 1st, 2nd, and 3rd sessions was significantly increased (2.13, 2.97, 2.97, respectively, p<0.001). The mean score of medication information awareness at the 2nd and 3rd sessions was 1.72 and 1.75, respectively (p=0.872). The medication compliance at the 2nd counseling was higher in the group with medication usage awareness scores of 3 (n=49) than in the group with scores of 2 (n=2; p<0.001). Conclusion : Medication counseling could enhance the awareness of medication usage and the compliance. However, there was no significant difference in the awareness of medication information after repeated education. These results suggest that additional improvement in packaging and clear labeling could be more helpful than enhancing drug information education.
