Risk factors associated with medication ordering errors.
Computerized provider order entry (CPOE) can prevent prescribing errors. In this study, researchers assessed voided medication orders to characterize medication ordering errors. Duplicate orders and improperly composed (wrong route, dose, strength, schedule) orders were most common and three-quarters were intercepted prior to administration. Risk factors for medication errors were multifactorial, arising from technological, cognitive, environmental, social, and organizational-level factors.
