VI. Description of framework, architecture or model

The following paragraphs derive directly from the scope and purpose statement of the draft standard.

Scope:

This standard specifies the recommended approach for modeling the health care environment in an object-oriented paradigm. It is intended for use by organizations developing standards for information interchange between health care information systems. This standard specifies the graphical and textual notations used in defining the information model, and procedures for defining conformance and compliance. This standard also specifies procedures for evolving the information model.

Purpose

This standard defines notations and recommends procedures for development of standardized components of an overall object-oriented information model to be used in health care data interchange. The use of consistent notation and procedures facilitates modular development of the overall model and facilitates the development of a family of standards to provide for health care data interchange

The intent of this framework specification is to provide a common way for healthcare information standards organization to develop their information models, in order to facilitate comparison and sharing of those models between SDO's. Implementation of this standard requires no particular tooling. Complete specification of information model can be derived from a literary expression created with a word processor.

It should be noted that the development of this framework was done as a Joint Working Group drawing members from ASC-X12N, ASTM, DICOM, HL7, and IEEE.

VII. Readiness of framework, architecture or model

Two drafts of this framework have been published - in 1994 and 1996. The 1996 draft has been freely circulated to interested parties in a variety of healthcare information interchange organizations.

Electronic reproductions of the April 1996 release can be obtained at http://www.mcis.duke.edu/standards/ieee/jwg-model/ in files stdmain.pdf and stdanex.pdf.

This framework has been implemented in the modeling activities of at lease HL7, ASC-X12N, and DICOM.

The full framework is available. Extensions to incorporate use-case modeling and related models are under consideration. The P1157.1 committee intends to seek a ballot on this document in 1997.

This framework is not dependent on the availability or selection of any particular tool. Indeed, several tools currently on the market will support modeling in this methodology. The use of the framework is not dependent on any RFI or RFP process.

VIII. Indicator of Market Acceptance

Over 150 paper copies have been produced and distributed. It is not known how many electronic copies have been acquired. The methodology has been implemented in at least three SDO's as part of their own information modeling activities. This framework is not known to be in use in other countries.

HL7 is committed to using this framework as part of its larger message development framework for Version 3.

IX. Level of Specificity

I am uncertain of the intent of this question and therefore cannot respond.

X. Identifiable Costs

Cost of acquisition will involve simply the purchase cost of a copy of the standard from the IEEE on the order of $100 to $400. Additional costs to adopt a compatible framework within any given SDO are entirely dependent upon the technological and political preparedness of that SDO to move to a formalized, model-based methodology.

Project #: P1157.1

Title: Standard for Healthcare Data Interchange - Information Model Methods

Scope: The scope of this document is to specify the approach used within the P1157 family of standards for modeling the health care environment in an object-oriented paradigm. This document specifies the graphical and textural notations used in defining the information model, procedures for registration of globally unique identifiers, and procedures for defining conformance and compliance. This document also specifies procedures for evolving the information model and for defining local specializations. The scope of the family of standards is to provide for healthcare data interchange in the open systems environment.

Purpose: This document defines notations and procedures for development of standardized components of an overall object-oriented information model for use in P1157 healthcare data interchange. The use of consistent notation and producers facilitates modular development of the overall model. The purpose of the P1157 family of standards is to provide for healthcare data interchange in the open systems environment.

Project #: P1157.1.1

Title: Standard for Healthcare Data Interchange - Common Healthcare Objects

Scope: The scope of this document is the specification of common healthcare objects which are the basis for specialization by other standards in the P1157.1 Information Model.

Purpose: The purpose of this document is to provide a common repository for base object classes which are used by multiple standards in the P1157.1 Information Model. The use of a common set of base objects is intended to promote consistency in the specializations defined by other standards in the P1157.1 Information Model.

Project #: P1157.1.2

Title: Standard for Healthcare Data Interchange -Registration Admission/Discharge/Transfer

Scope: The scope of this document is the specification of an object-oriented model of the subject domain of patient Registration, Admission, Transfer, and Discharge.

Purpose: The purpose of this document is to provide an object oriented model which supports the specification of healthcare data interchange transactions involving the subject domain of Registration, Admission, Discharge, Transfer.

Project #: P1157.1.3

Title: Standard for Healthcare Data Interchange - Laboratory

Scope: The scope of this document is the specification of an object-oriented model of the subject domain of Laboratory including, but not limited to, Chemistry, Hematology, Immunology, and Microbiology. There may also be application in Anatomical pathology, that is, Cytology, Histology, and Autopsy.

Purpose: The purpose of this document is to provide an object oriented model which supports the specification of healthcare data interchange transactions involving the subject domain of Laboratory.

Project #: P1157.1.4

Title: Standard for Healthcare Data Interchange - Radiology

Scope: The scope of this document is the specification of an object-oriented model of the subject domain of Radiology.

Purpose: The purpose of this document is to provide an object oriented model which supports the specification of healthcare data interchange transactions involving the subject domain or Radiology.

Project #: P1157.2

Title: Standard for Healthcare Data Interchange -Interchange Format Methods

Scope: The scope of this document is the definition of the methods used for specification of standardized transactions in theP1157 family of standards. This document defines the models for mapping from the information model defined by the P1157.1.n standards to standardized transactions for healthcare data interchange. Wherever possible, the interchange formats and representation profiles used by this family standards will consist of specialization's of F-type International Standardized Profiles (ISPs)as defined by ISO TR 10000.

Purpose: This document provides a model for message specification at the application level for the P1157 family of standards. The model forms the basis for specification of messages based upon particular interchange formats and representation profiles. The goal is to leverage F-type ISPs wherever possible, focusing on specialization for the needs of healthcare data interchange where necessary.
