Medical data abstractionism: fitting an EMR to radically evolving medical information systems.

Growing and maintaining a simple and flexible EMR (Electronic Medical Record) becomes a complicated task in light of diverse and distributed legacy data representation, advancing technologies, changes in medical practice and procedure, and changes in data regulation. Utilizing several abstraction mechanisms can simplify application development and maintenance, and provide flexibility for data evolution and migration. Newer applications built on these abstractions can be the beneficiary of slower obsolescence and lower maintenance costs.

Integrating detailed clinical models into application development tools.

Several groups are currently working on defining detailed clinical models (also called templates or archetypes) that are refinements of abstract medical models like the HL7 (Health Level Seven) Reference Information Model. At IHC, we have created over 3,000 detailed clinical models in the last five years. These models have become an essential part of the architecture of our electronic medical record (EMR) system. As a result, we have created an increasingly sophisticated set of tools that allow the models to be searched, viewed, and ultimately incorporated into medical applications. These browsers have some commonality with terminology browsers, but are distinct in that the explicit structure of the information models must be accommodated. In this paper we report our experience in making browsers for detailed clinical models that are integrated with application authoring tools.

Standards for detailed clinical models as the basis for medical data exchange and decision support.

INTRODUCTION: Detailed clinical models are necessary to exchange medical data between heterogeneous computer systems and to maintain consistency in a longitudinal electronic medical record system. At Intermountain Health Care (IHC), we have a history of designing detailed clinical models. The purpose of this paper is to share our experience and the lessons we have learned over the last 5 years. DESIGN: IHC's newest model is implemented using eXtensible Markup Language (XML) Schema as the formalism, and conforms to the Health Level Seven (HL7) version 3 data types. The centerpiece of the new strategy is the Clinical Event Model, which is a flexible name-value pair data structure that is tightly linked to a coded terminology. DISCUSSION: We describe IHC's third-generation strategy for representing and implementing detailed clinical models, and discuss the reasons for this design.
