Abstract

A medication management system which includes three components to assist a patient control, monitor and manage administration of prescribed medications. The system comprises a patient component having a retrievable patient database of patient medical history, prior prescribed medications and current prescribed medications, and it includes a data transfer interface, e.g., a hardwired interface, such as an RS232 interface or infrared data transfer port. The system also includes a physician component having a retrievable physician'"'"'s database of medication information and an input/output device enabling a prescribing physician to enter prescription information into the physician component. The physician'"'"'s database is capable of receiving and storing patient data transferred from the patient component through said data transfer interface. The system finally also includes a pharmacist component resident on a pharmacist'"'"'s computer. The pharmacist'"'"'s computer is adapted to interface with said patient component to transfer prescription data to said pharmacist component. At least one of or each of the physician component and the pharmacist component has the capability of searching a medication database to determine potential medication interactions with currently prescribed medications and identify those to the physician or pharmacist for selective downloading to the patient component so that the patient can be alerted to the potential interactions. The patient component has a scheduler which tracks a plurality of medication dose schedules and includes alarm functions to prompt a patient to take particular medications, reschedule them, and alert the patient to potential interactions between medications and/or provide caution information to the patient for administration of the medication.
