Abstract: A system for a community-wide health information infrastructure incorporates applications of information technology in conjunction with an incremental approach that creates incentives for voluntary participation for health care providers, payers, and patients from the onset. It identifies the hierarchical importance of categories of medical and health information and sets forth a systematic approach to utilize that hierarchy to establish a composite personal medical or health record for each individual.

Abstract: An information search system incorporating computer algorithms that provide for (1) enforcement of compliance with a standardized vocabulary by a user or users, in a manner that is much more acceptable to users than known existing methods; 2) instant or essentially instant provision of information that is context sensitive, that is, sensitive to the sequence of characters that are entered by a user, in a manner that is highly acceptable to users.

Abstract: A electronic medical record keeping system includes a central data collection and data storage server linked via a network to different health data input sources each of which provides controlled unidirectional input data via a first encryption key code for individual patients thereby enabling assimilation of data in the central server uniquely for each patient segregated from all other patient data, and which further includes a second encryption key code for the patient correlated with the first key code to enable (1) initiation of a set of tool bar screens at a terminal accessed by the patient (or doctor if authorized) and (2) bidirectional network connection to the unique patient data stored in the remote server.
