  • Publication number: 20020040305
    Abstract: After getting access to a hospital terminal from a patient terminal via a host computer of a medical care information managing apparatus, and browsing an appointment-status database of the hospital terminal to find an available appointment, a patient may make an appointment. A doctor accesses the host computer during or after a medical examination, and records the medical examination result and the prescription in a directory area for the patient, which is formed in a patient information database. The prescription information is transmitted to a terminal in a pharmacy in the patient's neighborhood or to a specified pharmacy. Accordingly, after completion of the medical examination, the patient can go home without having to wait to receive the prescription, and can receive medicine from the pharmacy. This reduces the patient's waiting time before and after the medical examination at the hospital.
