A health information
architecture is a blueprint that describes the general structure of
information in the health domain. It may be applied to a
particular component of an information system, such as a REG-ADT module,
to the entire system, such as an electronic health records system, or it
may describe the information within an entire enterprise or organization,
such as a medical center or payor. It may structure the
information needed to manage the health and well being of a patient
population. An information architecture is essential to provide
an overall view of information from which information systems and
particularly databases can be
efficiently and accurately constructed.
A health information architecture is usually expressed as a collection of related models. Collectively, these models describe the reality of the healthcare organization and its environment. These models may describe the organization's past, present, or one or more possible futures. These models may exist in many forms in both structured and object-oriented paradigms. These models also exist in countless iterations and with almost infinite variety. Basic types of models in the information architecture are the business or functional model and the data model. Both types of models can exist in the conventional structured paradigm or in the object-oriented paradigm. Typical applications of an information architecture with its models include transactional systems, data repositories, data warehouses and variants like data stores and data marts. The single greatest opportunity in health information architecture is the benefit in patient safety and quality of care enabled through clinical intelligence, the health care equivalent to business intelligence in the corporate world. These pages are under construction. These pages present an overview of enterprise architecture, modeling, and applications to introduce these concepts and applications to senior management, project managers, and technical associates. Some topics will be historical, other will provide a more theoretical review, while others will deal with the basics of information architecture and modeling in health and healthcare. These pages provide the introduction to the more detailed information provided in the Research and White Papers pages. |
