Relationship between incident types and impact on patients. The occupancy rates of preparation errors, incidents more than Level 0, 1, and 2 in the drug efficacy similarity (+) group were 81.3% (488/600), 68.2% (45/66), 57.1% (4/7), and 25.0% (1/4), respectively. On the other hand, the same rates in the drug efficacy similarity (−) group were 18.7% (112/600), 31.8% (21/66), 42.9% (3/7), and 75.0% (3/4), respectively. Consequently, the occupancy rate of preparation errors, incidents more than Level 0, 1, and 2 in the drug efficacy similarity (−) group increased gradually according to the rise of patient damage.
