| Summary: | 碩士 === 亞洲大學 === 資訊工程學系碩士班 === 94 === It is estimated that over three-quarters of a million people are injured or have died in hospitals each year caused by adverse drug events. The majority of medical errors result mainly from poorly designed health care systems rather than from negligence of health care providers.
While there are considerable evidences that information technology can be used significantly to reduce medication errors and adverse events, information technology, to be effective, must be implemented by using a system approach.
Medication errors and preventable adverse drug events are so common that about half of the medication errors occur during medication ordering. For physicians, prescribing of drugs is one of the most common daily practices. Doctors have considered alert messages very valuable during drugs prescribing for error-preventive health information.
The most common frustrations for prescribing are : (1) not having the instant and real time alert messages, (2) not having patient-oriented interface to maintain health information , and (3) not having the flexibility to customize the alert message.
High-quality Outpatient Prescribing System has to be emphasized to reduce the prescribing problems that are caused by omission of alert messages. The evidence for error reduction with Outpatient Prescribing System is based on the actual practices of patients applied to the "homegrown" systems, and is not from the commercial products available in the market.
