An image of a comic strip shows two birds on a branch above a person with mouth wide open to catch falling snowflakes. The text in the comic strip says, from one bird to the other, "Hey-are you thinking what I'm thinking?"

Slide 3

Best Manufacturing Practices for HIT

  • State of the (quality control) market.
  • Best practices (variation).
  • Opportunity lost.
  • Emerging landscape.

Slide 4

State of the Union (Quality Control)

  • Some (wide-scale) production examples:
    • Auto stop orders, juxtaposition errors, inappropriately flagged abnormals.
    • Not just commercial systems (VA, "home-grown").
  • Lack of consistent surveillance, labeling, client communications
    • Industry response to Koppel* findings is illustrative.
      • Would we have seen the same thing if report had been about 22 ways that Goodyear** tire design coupled with inflation pressure causes blowouts?
  • Industry is not immature, early lifecycle or teetering on the brink
    • Market cap of big 5 public (Cerner, McK, Siemens, GE, Eclipsys = $283B).
    • ~500 hospitals fully CPOE-adopted, many since mid-90s, some on 2nd.
    • 500M CPOE orders / yr (SWAG; Nobody knows).
    • 70M prescriptions / yr routed electronically; doubling year over year.

Slide 5

Best Practices (cGMPs*)

  • Design and testing (especially human factors).
  • Defect handling (where safety rubber really hits the road).
  • Surveillance (nothing even remotely systematic).
  • Org structure (lack of necessary checks and balances).
  • Structure → process → outcome
    • Unacceptable variation in HIT software quality can be directly attributed to manufacturing structural and process variations.

Slide 6

Window Closing on Self-Regulation?

  • 1986: The FDA states its HIT risk allocation rationale*
  • 1994: FDA moves blood bank IT systems to high risk.
  • 1996: FDA feigns retreat from yet-to-be-codified '86 position.
  • 1997: AMIA, CHIM, AHIMA and others push back**
    • '86 position should be written into doctrine.
    • Local oversight committees.
    • Voluntary product registration, adverse event reporting, labeling.
    • Vendor best manufacturing practices guide "in progress" by CHIM.
    • (2009: None of above happened, including codification by FDA, though unofficial doctrine still governs FDA risk-allocation policy for HIT***)

Slide 7

Learned Intermediary: Valid for HIT?

  • Basis for categorizing HIT as Class I device (lowest risk), but:
    • Legal doctrine developed to protect pharmaceutical manufacturers from liability related to malprescribing, not to protect HIT vendors from liability related to adverse events due to user errors.
    • Quite contrary to systems theory of human error*; implies that software can't systematically (and predictably) drive user error rates.
    • Importantly, this FDA pseudo-doctrine - as articulated by Young in '86 - was developed for a very narrow set of HIT functions (specifically, A.I.-based diagnostic and treatment recommendations), not for the typically full-featured** HIT of today (or of '97, for that matter).
    • What was AMIA thinking in '97 when it "commended" Young?
      • Did the end (no FDA reg of HIT!!) justify the means (learned intermediary), no matter how distasteful? Probably so, but a post hoc analysis is overdue.

*Ironically, systems theory was heavily invoked in the 1990s in order to justify why HIT was necessary in the first place - especially CPOE (see Berwick DM. A primer on leading the improvement of systems. BMJ. Mar 9 1996;312:619-622).

It's the User's Fault...

Intelligent Intervening Provider
(aka "learned intermediary")

Slide 9

Evolving Regulatory Landscape

  • Lack of regulation + indemnification = no accountability
    • By the way, CCHIT's mission has little to do with ensuring public safety.
  • Policy agenda tied up w/ MU, privacy/security, workforce.
    • Missed opportunity for resource allocation during ARRA "ask" period.
    • Fear of spooking the funders (shame on us for not bringing up safety).
  • Legal and non-HIT engineering communities speaking out
    • Hoffman & Podgurski. Harv Rev Law & Tech. Feb '09 and http://works.bepress.com/sharona_hoffman/7/
  • Sweden* and the EU.
  • FDA's MDDS proposal, otoh, newly endorses past approach**

Slide 10

What's Next?

  • AMIA Task Force (on vendor contracting; not on regulation).
  • If stick with HIT-as-low-risk approach, need a new framework to justify it! (learned intermediary is... well... embarrassing).
  • In parallel with addressing "reg vs. no reg", should be thinking about ideal components of a workable reg program
    • Most impact on best practices with least resource investment.
    • What can we learn from blood bank IT regulation?
    • Might forced compliance to cGMPs, with auditing, be enough?
  • Too late for voluntary adherence to best practices?
    • Perhaps not, but usability - which CCHIT and HIMSS have suddenly embraced (that's a good thing) - is only one piece.
    • Defect handling, surveillance, and org structure must also be addressed.
    • 1/09: CCHIT rejected a proposed vendor best practices program.
