MedBiquitous Virtual Patient Standard: A Technical Overview

®

What are virtual patients?

“interactive computer programs that simulate

real life clinical scenarios and provide an

effective way for healthcare professionals to

not only learn about a wide range of clinical

topics, but to practice in a virtual and

therefore safe environment.”

®

MedBiquitous Virtual Patient Standard (MVP)• A technical specification for the exchange of

Virtual Patient activities across Virtual Patient systems

Institution A Institution B<XML>

Does my VP System fit?

• Digital – XML• Delivery

• Web-based• Mobile• Virtual worlds

• Navigation• Linear• Branching• Global

• A representation of data

• Must be interpreted by a runtime system

• Output: zip file of XML documents and media

®

Current Limitations

• Does NOT encode artificial intelligence algorithims

• Does NOT encode physiology engine rules and models

®

The MVP Architecture

Virtual Patient Data

Data Availability Model

Media Resource

ActivityModel

Player Functional Specification

®

• Personal and clinical data

• Similar to a clinical chart

• May include references to healthcare terminologies

Virtual Patient Data

®

• Images, animations, videos, etc.

Media Resource

®

• Aggregates virtual patient data and media resources for reference in an activity

• Enables progressive disclosure of virtual patient data and media resources

Data Availability Model

Part 1: Patient History

Part 2:Diagnostics
