Abstract

A method and system that assists medical practitioners who treat or prescribe treatment of patients having a medical condition which requires long-term profiling of medical data taken from the patient'"'"'s body. Medical practitioners, their assistants, and patients take medical readings of predetermined medically important variables. These readings are stored as raw data in a data receptacle such as a smart card or in a portable medical instrument, then input into a remote computer, or the raw data is manually entered into a remote computer. The remote computer then connects with a primary computer using a communications connection and transmits the raw data to the primary computer system which maintains a database of patients and their medical readings. The communications connection can be any means of connecting two computers for communication therebetween but is preferably an Internet connection wherein the remote computer is operated as a web client and the primary computer is operated as a web server. The readings can also be transmitted to the primary computer using an ordinary telephone to call a telephone peripheral which can receive the raw data using automated speech recognition or touch-tone recognition. Requests for data by medical practitioners is transmitted to the primary computer in a manner similar to the transmission of raw data. In response to a request for data, output, in the form of a chart or graph, or multiple charts and graphs, is transmitted to the remote computer for display on the computer screen and/or printed for hard copy, or faxed to the medical practitioner or assistant.
