Importance of Standards HL7 (Health Level 7) –Simple protocol to exchange information Current version of HL7 is Version 2.x Version 3.x compliant with XML – Extensible Markup Language CCOW (Clinical Context Working Group) –Simplify and improve workflow and functionality between applications DICOM (Digital Image and Communication in Medicine) –A true standard dealing with objects – images > series > study>patient –Deals with images, waveforms and structured reports IHE (Integrating the Healthcare Enterprise) –Focuses on the interoperability within & between departments in the enterprise. 7©2007 Koller Associates, Inc.

Lessons & Landmines from Radiology Modality PACS - Standards “Grey” Areas –Limited inter-vendor compatibility in early years ROI –Can we really eliminate film? Installation of xIS prior to or with PACS –The installation of Image Management prior to Workflow Management introduces potential for errors and lost studies. The 2 nd PACS Challenge –Was it truly stored in a standard format? –How is all the data migrated when changing vendors? 12©2007 Koller Associates, Inc.

Technology Obsolesce & Data Migration Technology Obsolesce –12” & 14” Optical Disk –9 - Track Tape Data Migration –Usually Application Vendor Dependant –Long Migration Times (Can be Years) How long do you have to keep data? 13©2007 Koller Associates, Inc.

Backup Vs. Archiving Backup When to Use? –Variable Content Data –Transactional w/ Small to Medium Records –Commercial Database Examples –HIS / RIS / LIS Databases –Image Pointer Database Backup Management –Create Regular Backups –Manage & Rotate Multiple Generations –Database Snapshots & Replication Archiving When to Use? –Fixed Object Based Content –Long-term Retention Requirements –Large Volume of Objects Examples –PACS Image Database –Other Large / Fixed Content Objects Archive Management –Create Data Protection & Retention Policies –Automate Everything Possible 15©2007 Koller Associates, Inc.

Image Data Management How can your image data be managed? Let your Image Application (PACS) vendor decide. –Dependent on vendor for all storage & future migration. Use an all disk solution with multiple copies managed by vendor. –No real intelligence –Not responsive to conditions affecting individual data objects –Still potentially dependent on applications vendor for future migration. Use an HSM to archive your images. –Better control, but minimal metadata for policy-based automation. –No Linkages Back to Application System for Aging of Studies –Still potentially dependent on vendor for future migration. Use an Information Lifecycle Management (ILM) strategy. ILM – What is it? 16©2007 Koller Associates, Inc.

Definition of ILM Information Lifecycle Management is comprised of policies, processes, practices and tools used to align the business value of information with the most appropriate and cost effective IT Infrastructure from the time information is conceived through its final disposition… Source: SNIA Data Management Forum 17©2007 Koller Associates, Inc.

ILM – What is it? What ILM is not! –Hardware, –Software, –A product! Depends on the Vendor – DLM? ILM? xLM? All Solutions Should be Standards-based (if possible) ILM = DLM + Awareness of Business Value of the Data The Entire Life of a Information Object is Pre- destined at Time of Creation, But … 18©2007 Koller Associates, Inc.

DLM vs. ILM Data Lifecycle Management –Focus is to make efficient & cost effective use of storage resources –Based on basic characteristics of the data and data access –Basic Metadata Date/Time, Last Access, Owner Object Size, System Watermark Information Lifecycle Management –Requires information about business processes (application aware) –Holistic view of managing information –Robust Metadata DICOM, Derived from HL-7, Other –Uses functions of data lifecycle management Excerpted from Storage Industry Primer by Dennis Martin RMWTUG – Fall ‘05 ILM Application & Business Process DLM Processing Storage Tier 1 Storage Tier 2 Storage Tier 3 19©2007 Koller Associates, Inc.
