A Zen Definition of Middleware
![Page 4: Increasing Lab Efficiency and Productivity with Middleware ......Increasing Lab Efficiency and Productivity with Middleware: A Case Study Approach Jay B. Jones, PhD ... Middleware](https://reader030.vdocuments.us/reader030/viewer/2022040215/5eccd44e4f2cc4339c475c4b/html5/thumbnails/4.jpg)
A Functional Definition of Middleware
A growing family of utilities which enable data to interoperate within diverse information systems.

3 Case Studies of Implemented Middleware with Outcomes
1) Global - Layers of MW integrated into the clinical enterprise for connectivity & decision support (e.g. comparative clinical effectiveness)
2) Integrative – Application of blood gas instrument enterprise server to connect LIS and CV-OR and to “lean” the testing process
3) Focused - Use of a web tool for displaying real time lab test “pending lists” via enterprise intranet
![Page 8: Increasing Lab Efficiency and Productivity with Middleware ......Increasing Lab Efficiency and Productivity with Middleware: A Case Study Approach Jay B. Jones, PhD ... Middleware](https://reader030.vdocuments.us/reader030/viewer/2022040215/5eccd44e4f2cc4339c475c4b/html5/thumbnails/8.jpg)
1. LIS foundation “info-structure”
• WAN routers connect to Data Center and “Rack & Stack” Client Server LIS (SunQuest)
• 28 (virtual)CS apps from Lab alone• $80M spent on EHR (EpicCare)
![Page 9: Increasing Lab Efficiency and Productivity with Middleware ......Increasing Lab Efficiency and Productivity with Middleware: A Case Study Approach Jay B. Jones, PhD ... Middleware](https://reader030.vdocuments.us/reader030/viewer/2022040215/5eccd44e4f2cc4339c475c4b/html5/thumbnails/9.jpg)
1. LIS foundation “info-structure”
• Single LIS on WAN • LIS – standardized
“lean informatics”• Connected to billing,
EHR “mainstream”• Middleware
embedded for connectivity & functionality
![Page 10: Increasing Lab Efficiency and Productivity with Middleware ......Increasing Lab Efficiency and Productivity with Middleware: A Case Study Approach Jay B. Jones, PhD ...

1. Integration into IDN “Mainstream” “Outcomes Institute”
• Lab parameters key to EHR Clinical Repository (CDS)
• Clinical Effectiveness Division• Outcome parameters for
reimbursement under P4P• “ProvenCare” Outcome warrenty• Incentivized best practice in EHR• System dashboards for best practice• AHRQ grant for “RHIO”• CDS collaboration with IBM• NIH grants for population studies• Translational “D&r”• “MyCode” Biorepository• Diagnostics & Pharma collaboration• Excellent Outcomes & Health Care

1. LIS foundation “info-structure”“Enterprise Analytics”
• Scaleable Chem/Immuno (23), Heme, Coag, ABG, POCT on WAN
• Shared LIS test codes, methods, calibrator lot #, reference ranges, critical limits (“lean informatics”)
• Common lot # QC (400+ Chem/Immuno channels); affiliate QC reports; CAP web PT
• POCT Interleaved in EHR• Group purchased savings & efficiency• Benefits go on and on and on…

2. Advantages of Client Server Middleware Connectivity
• Minimizes hardware “feetprints” in lab• Enables & Encourages Enterprise
Standardization• Simplifies IT maintenance (esp with SANS,
virtual servers)• Centralizes data storage (i.e. scientific record)• Single point of vendor connection (e.g. QC)• It works

3. Enhancements for Outreach“Real-time” TAT Monitor
• Developed in-house with “Cold Fusion” (Now Adobe Flex) web tool
• Each lab location manages via its own URL• URL includes user test, time windows, 24/7 large
screen location• can add sound (e.g. .wav file) and color for alerts• Embraced by all but sound quickly turned off

“Real-time” TAT Monitor, Outcome
• Saved labor by avoiding pulling hourly pending logs
• Especially outlier TAT misadventures decreased (Mean merged into Mode TAT)
• Changing TAT to encompass collect time result time (compliant with JC
requirement to monitor total TAT for “critical tests”)

“IVD Industrial Connectivity Consortium (IICC)”
• Organizing sponsored by AACC• Broad goal is to promote interoperability
between instruments and their host IT systems with defined standards
• Patterned after CIC-1• Organizational meeting Oct 2007 in
Tarrytown, NY• Governance now being formalized

NCCLS POCT1-A Connectivity• Connectivity Industrial
Consortium (CIC) now sunsetted
• Formal Governance structure in 2004
• Funded by voting CIC members
• Well documented specs in a year
• Handoff to NCCLS (now CLSI)

Final Thoughts
• As you layer in Middleware applications, think about how they fit into the entire enterprise
• Middleware is in a germinal state and will accelerate its growth with associated maintenance issues
• Plan and budget for licenses at Middleware “touch points”
• Try to keep it as simple as possible
