## Overview

Medical-Objects Pty Ltd (MO) is an Australian company that specializes in electronic messaging and clinical applications. They are also active in healthcare standards development and have been key contributors to HL7 GELLO and GLIF. MO works closely with business, government, and health professionals to provide clinical tools which help with connectivity, integration, and workflow. MO has developed several [CDS tools](https://kb.medical-objects.com.au/display/PUB/Clinical+Decision+Support) including:

* A GELLO Release 2 (R2) editor, engine, and RESTful web service. (The GELLO editor is shown below in Figure 3.)
* A GLIF editor, engine, and web service. (The GLIF editor is shown below in Figure 4.)
* An ISO 13606 archetype template editor

## GELLO

[GELLO](/snomed-ct-practical-guides/snomed-ct-clinical-decision-support-guide/4-inference-engine.md#gello) R2 i s an ANSI and HL7 standard for clinical decision support. It makes use of a virtual medical record (VMR) to abstract and present clinical data. As a language, GELLO is both declarative and functional and can query SNOMED CT and other reference terminologies.

The screenshots below illustrate the use of an *implies* method which uses SNOMED CT subsumption with the [ISO 21090 CD datatype](https://kb.medical-objects.com.au/display/PUB/ISO+21090+Datatypes+Guide#ISO21090DatatypesGuide-ISOCD-ConceptDescriptorType) ( concept descriptor). Note that \_ allergies \_in line 2 of the screen shot below, comes from the vMR instance.

<figure><img src="/files/FGWJztitX7VDPMcYIGJJ" alt=""><figcaption><p>Figure 2: The same GELLO query running on Medical-Object's web service</p></figcaption></figure>

MO is in the process of migrating its GELLO R1 SNOMED CT object to the new GELLO R2 format. The screen shot below captures some of the added functionalities. Note the use of SNOMED CT attribute relationships in the language, specifically [<mark style="color:blue;">|</mark> Finding site<mark style="color:blue;">|</mark>](http://snomed.info/id/363698007) and [<mark style="color:blue;">|</mark> Associated morphology<mark style="color:blue;">|</mark>](http://snomed.info/id/116676008).

<figure><img src="/files/xvZEVimU6oN81qxiI8wR" alt=""><figcaption><p>Figure 3: GELLO R2 object which illustrates the use of SNOMED CT attribute relationships</p></figcaption></figure>

MO has found that being able to write GELLO queries to access both the information model (e.g. VMR, archetypes) and the terminology model (e.g. SNOMED CT) has been extremely useful.

## GLIF

[GLIF](/snomed-ct-practical-guides/snomed-ct-clinical-decision-support-guide/3-knowledge-base/3.2-guidelines.md#guideline-interchange-format) (GuideLine Interchange Format) is a clinical guideline representation protocol for exchanging clinical guidelines. It uses GELLO (and therefore can use SNOMED CT) in its automated decisions and state declarations. To the user it looks like a smart flowchart of guidelines and sub-guidelines with an interactive interface presenting such things as pop up [didactics](https://en.wikipedia.org/wiki/Didactic_method#Didactic_teaching). The diagram below depicts a user interface view of a SNOMED CT based query in GLIF:

## Deployments

GLIF and GELLO are incorporated into the Medical-Object's *Explorer* EHR software. The diagram below is a screenshot of a guideline, that is represented in GLIF, being used.

Terminology-enabled GELLO was made available as part of MO's contribution to the [Veterans Health Administration](https://www.va.gov/health/) (VHA) [CHIO Innovation](https://sites.google.com/site/enhancedcprscds/home) project. MO has started to see some adoption of SNOMED CT based querying of GELLO in pathology laboratory panel archetypes.

An example gastroenterology archetype is shown in the sequence of figures below. This archetype is currently in development for a gastroenterology clinic. If an endoscopy is being performed for a Barrett's esophagus type of lesion, then [visibility](https://kb.medical-objects.com.au/display/PUB/Node+Visibility) GELLO displays relevant extra nodes. (Note: Visibility GELLO can be used for developing smart forms to show or hide nodes depending on values entered elsewhere.)
