Systems
3
Benefits of CDS
Improved quality of care
Better health outcomes
Avoidance of errors and adverse of events
Improved efficiency
Reduced costs
Increased provider/patient satisfaction
4
CDS is Not Widely Available
CDS is complex
CDS capabilities have been tightly coupled with specific institutions
and health IT systems
Re-using CDS implemented elsewhere is difficult
5
The Need
Application-independent CDS resources that can be
efficiently leveraged by diverse healthcare systems and
health IT settings to improve patient health
OpenCDS
6
Collaborative project, led by Dr.
Kensaku Kawamoto at the
University of Utah
A software platform and toolkit
for developers implementing
CDS services
Open source
www.opencds.org
7
ICE Project
Collaboration of public health agencies, academic researchers, and a private firm
Leveraged OpenCDS to implement CDS for immunizations (aka “immunization forecasting”)
Needed by providers and public health agencies
The ICE Project
ICE Software System
ICE Web Service Provides immunization forecasting to clinical
systems through a web service interface Supports routinely administered vaccine
groups, from infant to adult
CDS Administration Tool (CAT) Web-based tool enables non-technical subject
matter experts (SMEs) to manage ICE Human readable rules
10
ICE Web Service
Inputs: DOB, gender, immunization history, disease
immunity Immunization schedule identifier, date of
evaluation
Outputs: Validity of immunization history + reasons Immunization recommendations + reasons
Sample ICE Deployment

12
Software Architecture
ICE/OpenCDS Tomcat or JBoss AS (aka “WildFly”) JBoss Drools (rule engine/database) JBoss jBPM (process/workflow) HL7 vMR (data model)
CAT JavaServer Faces (GUI) Enterprise JavaBeans (business logic) Apache Derby JVM (database)
13
Ease of Adoption and Integration with Clinical
Information Systems
14
Open-Source
ICE built with only open-source software No dependencies on any commercial
software Released under a standard open-source
license GNU Lesser General Public License
version 3 (LGPL v3) Any system (even proprietary systems) may
use/modify/integrate with ICE at no cost Any modifications to ICE software must be
shared No warranty
15
Flexible Deployment Options
Java-based system runs on variety of hardware/operating system platforms
Deploys on same or different server as the client system
16
Standards-Based Interface
Attribute of ICE
Conforms to Relevant Technical Standard
Messaging framework
Simple Object Access Protocol (SOAP)
Web Service interface
Decision Support Service (DSS) – an HL7 & OMG standard– http://hssp-dss.wikispaces.com
Data model Virtual Medical Record (vMR) – an HL7 standard– http://wiki.hl7.org/index.php?title=Virtual_Medical_Record_(vMR)

Technical Documentation ofICE’s Standards-Based Interface
19
Production Use of ICEby an EHR System
eClinicalWorks (eCW) v10 uses ICE to deliver evaluations and recommendations
Integrated by eCW developers, with minimal support from ICE team
No modifications to the default configuration
ICE is hosted by eCW at central location
20
Summary of the ICE Software System
Freely available
Standards-based
Easily integrates with other systems
Maintainable by non-developers
Collaboratively developed
Transparent
Can be leveraged for other types of CDS
21
Leverage Our Work
for Other Types of CDS
Drug interaction/allergy (warning)
Abnormal lab result (alert)
Ordering of appropriate lab test (critique)
Disease management (reminder)
Treatment/care plans (recommendation)
Automated redaction of sensitive data from clinical documents
