Guideline execution engine

A Guideline Execution Engine is a computer program which can interpret a clinical guideline represented in a computerized format and perform actions towards the user of an electronic medical record.

A Guideline Execution Engine needs to communicate with a host Clinical information system. vMR is one possible interface which can be used.

The engine's main function is to manage instances of executed guidelines of individual patients.

Delivering the inferred engine recommendations or impacts to the host Clinical information system has to carefully respect current workflow of the clinicians (physicians, nurses, clerks, etc.)

Architecture of Guideline Execution Engine
The following modules are generally needed for any engine


 * interface to Clinical Information System
 * new guidelines loading module
 * guideline interpreter module
 * clinical events parser
 * alert/recommendations dispatch

Guideline Interchange Format
The Guideline Interchange Format (GLIF) is computer representation format for clinical guidelines. Represented guidelines can be executed using a guideline execution engine.

The format has several versions as it has been improved. In 2003 GLIF3 has been introduced.
