A Virtual Medical Record (vMR) for Clinical Decision Support (CDS) is a data model
for representing clinical information inputs and outputs that can be used by CDS
engines and local clinical information systems, through mechanisms such as CDS
services, or execution of standardized clinical decision support logic by a GELLO
execution engine. A vMR for CDS is needed to enable the design and development
of scalable CDS resources that can be used across multiple healthcare institutions
and health information systems. Existing clinical data, from any source, is
virtualized to present a façade compliant with the vMR class model. Clinical logic
can then be executed against the data represented in the vMR model. GELLO is one
standard language that can be used with the vMR model, but other languages can
use the vMR model. GELLO is intended to be a standard query and expression
language for decision support. The clinical usage of the GELLO language depends
on an object-oriented data model.
The objective of the HL7 CDS Work Group’s vMR GELLO Implementation Guide is to
define a BNF (Backus-Naur Form) for defining a vMR which allows tight integration
of a vMR model with a GELLO compiler or any other rule execution engine or
authoring environment, ensuring good interoperability of CDS logic between
institutions. This guide describes a grammar for defining the vMR classes and data
types. It does not attempt to define the final structure of the vMR, but defines a
standard mechanism for defining vMR classes and data types. The final VMR would
be encoded in this format allowing compilers access to a standard, rigorously
defined VMR model. This format will be identical to the semantics of a UML XMI
representation, but is compiler friendly and more human readable. While GELLO has
been defined by HL7 CDS Workgroup for encoding standards based decision
support logic, the vMR as defined by this format could be used in any execution or
authoring environment to tightly define data types, class structures and methods.
The classes and data types defined by this format are built on the base GELLO
types which are based on the OCL types used in UML. The format is designed to be
language neutral, and should be useable to any object based execution environment
that supports the base UML data types.
This is the first DSTU ballot for this material. Input is sought on the format rather
than the content, as a normative vMR model will be defined elsewhere using this
grammar. It is envisaged that all elements of the final vMR, when this is finalised,
will be represented in both UML (.xmi files), class diagrams, and this format. As this
format is both human and machine readable it is intended to make this format a
more readily understandable form of the vMR standard.
It would be possible, by the use of this format, to define a class model which
represents a concrete instance of a DCM (Detailed Clinical Model). A package
containing the required classes to represent data conformant to a DCM could then
be used to extend the available classes in a vMR execution environment.

2.1 Grammar for GELLO class definitions (Normative)
This is the GELLO class BNF which uses the Extended BNF syntax as used in the GELLO
standard. This BNF is the normative part of this standard.

definition as represented here is indicative of the use of the grammar and is
informative. The HL7 V3 Release 2 data type specification is abstract and cannot be
used directly. The ISO21090 xml schema files define content, but not operations. Data
types defined in this manner could be used by an execution engine or authoring
environment. The data types in the final vMR may be simplified further.

2.4 vMR Definition example (Informative)
A sample of a mock vMR is represented below to indicate how a vMR would be
defined using the grammar and imports the ISO21090 package. This example is
based on an import of a Green CDA schema and is not representative of the final
vMR but is an informative example of the use of the grammar. In this example the
Context classes (classes extending ContextClass), and Factory are specific to a GELLO
execution environment.

2.5 Detailed Clinical Model Example (Informative)
A mock urine laboratory report is used to illustrate how the grammar could be used
to define a detailed clinical model for use in clinical decision support. The content is
informative and is included to provide example usage of the grammar for defining a
class structure that is based on a detailed clinical model. A DCM could also be
incorporated by using the generic information structure included in the base vMR,
but this template constrains the structure to be semantically equivalent to the DCM
and makes writing logic against a DCM easier.
