Data Mining on Numeric Error in Computerized Physician Order Entry System Prescriptions

摘要

This study revealed the numeric error patterns related to dosage when doctors prescribed in computerized physician order entry system. Error categories showed that the'6', '7', and '9' key produced a higher incidence of errors in Numpad typing, while the '2', '3', and '0' key produced a higher incidence of errors in main keyboard digit line typing. Errors categorized as omission and substitution were higher in prevalence than transposition and intrusion. Computerized physician order entry (CPOE) system can significantly reduce certain types of prescription errors. However, prescription errors still occur. Various factors such as the numeric input methods in human computer interaction (HCI) produce different error rates and types. This study aimed to categorize the types of errors on different numeric keys when doctors prescribed using CPOE. Several error patterns in this study were compared with Salthouse's findings [1] and Lin & Wu's research [2].
