To explore the informatic requirements in the home care of chronically ill patients.

To compare three potential sources of controlled clinical terminology (READ codes version 3.1, SNOMED International, and Unified Medical Language System (UMLS) version 1.6) relative to attributes of completeness, clinical taxonomy, administrative mapping, term definitions and clarity (duplicate coding rate).

To determine the extent to which a combination of existing machine-readable health terminologies cover the concepts and terms needed for a comprehensive controlled vocabulary for health information systems by carrying out a distributed national experiment using the Internet and the UMLS Knowledge Sources, lexical programs, and server.

In mid-1996, the FDA called for discussions on regulation of clinical software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology has developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. Organizations assisting in development of recommendations, or endorsing the consortium position include the American Medical Informatics Association, the Computer-based Patient Record [...]

Telephone-Linked Care (TLC) technology has been developed and applied as an alternative to and a supplement for office visits as a means to deliver ambulatory care. TLC is used to monitor patients with chronic diseases, counsel patients on important health behaviors, and provide information and support to home caregivers of patients with disabling conditions. TLC speaks to patients over the telephone in their homes using computer-controlled digitized human speech. Patients [...]

To develop a knowledge representation model for clinical practice guidelines that is linguistically adequate, comprehensible, reusable, and maintainable.
