     How Does the Healthcare
     Research Context Differ?
• Mostly service model-based
• Analytical methods trail by a decade or more.
• Management engineers were phased out in the
  1990s.
• Healthcare is a complex system of delivery and
  stakeholders.
• Can you spell I-R-B (Institutional Review Board)?
• IE approach can represent ―disruptive innovation.‖
Healthcare is a Complex System of
   Delivery and Stakeholders.
  Fragmented information
  from various sources
  is used to make decisions
  on treatment for a patient
  who cannot judge clinical quality.

  Furthermore, the treating physician
  is an independent contractor
  paid by third parties (Medicare, BCBS, etc.).
       Can You Spell I-R-B?
• Not just at PSU, but the hospital IRB, clinic
  IRB, etc. Most won’t accept central IRB.
• Also, before you can conduct research
  – Get your shots (Hep B series, MMR, TB)
  – Attend mandatory orientation
• Get clinicians on board
• Next words: HIPAA, JCAHO
 IE Approach Can Represent
    ―Disruptive Innovation.‖
• Hospitals are used to ―sustaining‖ innovations
  (clinical, usually)
  – Specialized cancer treatments
  – Clinical trials
• But, systems to improve processes are
  typically ―disruptive‖
  – Noninvasive techniques, cure for common cold
  – Portable x-ray in MD offices
  – Low-tech, affect many patients with more ordinary
    health problems
  – Impact business processes, culture, MD status
Disruptive Innovations Come
        From Below.

    What Makes IEs Suited to
    Healthcare Improvement?
• Proficient in Proven Tools Used in Other
  Contexts
• Focus on Systems Tools and Applications
• Consideration of the Human in Complex
  Systems
• Conversant with IT
     IEs are Proficient in Proven
    Tools Used in Other Contexts.
•   Lean, TPS, Six Sigma
•   Work methods
•   Quality
•   Performance measurement and
    improvement
    – What do they measure in the ED?
    – Impact on pt flow, pt care
 IEs Have a Focus on Systems
    Tools and Applications.
• Failure Analysis (FMEA)
• Modeling and Simulation (MedModel)
• Enterprise Management Tools (supply
  chain) (incineration)
• System Dynamics
• Knowledge Discovery (data mining, neural
  networks)
   IEs Consider the Human in
       Complex Systems.
• Team structures and processes (Mayo
  model)
• Decision making
• Fatigue and error
• Work scheduling (resident shifts)
   IEs are Conversant with IT.
• Can coordinate projects with CS, IT
• Trained to identify system requirements for
  each stakeholder (PDA Rx order)
• Drive IT toward objectives of vastly
  improving access to necessary clinical,
  system, and patient information (med
  recon)
            Some Recent
          IE-Related Efforts
• Patterson (Ohio State/VA National Center for
  Patient Safety)—HF and adverse events
• Stanford—Culture of Safety
• VA National Center for Patient Safety—HFMEA
• Cook & Rasmussen—System Dynamics,
  lessons from nuclear energy
• Miller et al.—Six Sigma applications
• Banner Health (AZ)—Lean applications
• Pebble Partnership—Evidence-based design
    What are Some Research
         Opportunities?
• Medical Error
  – 100K Lives Campaign (IOM)
  – Medication error
  – Medication labeling
  – Order entry and Rx (delays & wasted $$ in
    dupe tests)
  1,000,000
―serious medication errors per
year‖ … ―illegible handwriting,
misplaced decimal points, and
 missed drug interactions and
          allergies.‖
  Source: tompeters.com from Wall Street Journal
            /Institute of Medicine
―In a disturbing 1991 study, 110 nurses
   of varying experience levels took a
 written test of their ability to calculate
medication doses. Eight out of 10 made
calculation mistakes at least 10% of the
                   time,
   while four out of 10 made
mistakes 30% of the time.”

    and Accountability in the Information Age, Michael Millenson
    What are Some Research
         Opportunities?
• Patient Flow
  – ED (50% of pts), inter-unit, to/from ancillary
    services
  – Waiting times, queuing
  – Essentially, Hammer’s ―reengineering‖ (pt
    admission in-room)
    What are Some Research
         Opportunities?
• Healthcare Information Technology (HIT)
  – Electronic medical record
  – Service and provider integration
  – Rx, treatment order entry and fulfillment
  – Bed availability (HMED)

"When I climb Mount Rainier, I face less risk of death than I'll face on the
operating table."—Don Berwick, M.D. Newsweek/12.12.2005
Study and Implement Now…
No Time to Wait for Optimal
     Tools or Solutions
                  Summary
•   IE tools have a place in medicine.
•   Now is the time to use these tools.
•   Lots of ―red tape‖.
•   Two cultures.
