FDA MAUDE Database: Patient Outcome - Death

I present another health IT problem case from the FDA's voluntary MAUDE (Manufacturer and User Facility Device Experience) database below.

From FDA's description of MAUDE:

  • MAUDE data represents reports of adverse events involving medical devices. The data consists of voluntary reports since June 1993, user facility reports since 1991, distributor reports since 1993, and manufacturer reports since August 1996. MAUDE may not include reports made according to exemptions, variances, or alternative reporting requirements granted under 21 CFR 803.19.
  • The on-line search allows you to search CDRH database information on medical devices which may have malfunctioned or caused a death or serious injury. MAUDE is scheduled to be updated monthly and the search page reflects the date of the most recent update. FDA seeks to include all reports received prior to the update. However, the inclusion of some reports may be delayed by technical or clerical difficulties.
  • MAUDE data is not intended to be used either to evaluate rates of adverse events or to compare adverse event occurrence rates across devices. Please be aware that reports regarding device trade names may have been submitted under different manufacturer names. Searches only retrieve records that contain the search term(s) provided by the requester.

I somehow missed the following case when I wrote the Oct. 2009 post 'Our Policy Is To Always Have Unabashed Faith In The Computer ... Except When It Screws Up, And Then It's The Doctor's Fault' but I have added it there as well:

CERNER MILLENIUM POWERCHART CPOE
Event Date 11/19/2006
Event Type: Death
Patient Outcome: Death

The medication review screen of the subject device does not specify the exact dose in milligrams of combination medications. For example, narcotics are combined with tylenol in at least two strengths. Liquid narcotic tylenol-oxycodone combination is reported in ml, not mg. The exact dose of tylenol is not specified and requires knowledge of the combination medication dose in the volume specified.

Certain fields of the grid do not specify the volume, but rather state "date/time" requiring another click or pop up screen. The immediate knowledge of tylenol dosage in mg is directly related to understanding and preventing excessive doses. In the subject, 10 ml of acetaminophen-oxycodone is indicated as having been given 3 times over 4 hours. That means that 1950 mg of tylenol was administered in 4 hours while the patient was in a state of starvation and receiving other medication that increase the effects of tylenol.

This dose would equate to 11,700 mg of tylenol over 24 hours, nearly 3 times the maximum daily dose in otherwise health people. In the ensuing days, the patient developed acute renal failure, presumably acute tubular necrosis, and died. In the absence of other etiology, the excess tylenol was the culprit. This was not considered as etiology ante-mortem. The counterintuitive screen impaired the professionals. The pharmacist did not recognize and stop the medication, the nurses administered it, and the excessive dose, clinically meaninglessly listed as a volume of 10 ml -given 3 times in 4 hours- of acetaminophen-oxycodone, was missed by the physicians. Adverse events have been ascribed to "user error" by vendors.

The device offers a potent propensity to life endangering oversights. There are other screens on this device which present information that interfere with clinically useful visualization of data.
[Who designed these screens, I ask? Clinicians, or business IT personnel used to designing inventory systems for widget control? - ed.] The data does not flow to the professionals. It is not represented in a meaningfully useful manner.

The professionals need to hunt for it. As such, the user unfriendly screens [see this link on mission hostile HIT - ed.] impair safe medical care consistent with the impediment to expedient professional understanding of what, exactly, is the dose of medication and how much was administered to the patient. This sentinel case of death is directly attributed to user unfriendly screens on this device.

How many cases like this, as well as "near misses" related to health IT go unreported, nationwide and worldwide?

As in my paper "Remediating an Unintended Consequence of Healthcare IT: A Dearth of Data on Unintended Consequences of Healthcare IT",
nobody really knows; these devices are unregulated with no requirements for reporting.

However, let's roll it out nationally anyway, because HIT will deterministically "revolutionize" medicine. Just ignore those spoil-the-party, man-behind-the-curtain prattle from writers like these.

We can safely ignore all contrarian research and literature, of course, as we all know HIT will revolutionize medicine from the definitive certainty of HHS in "The 'Meaningful Use' Regulation for Electronic Health Records", NEJM, Blumenthal and Tavenner (10.1056/NEJMp1006114, July 13, 2010):

The widespread use of electronic health records (EHRs) in the United States is inevitable. EHRs will improve caregivers’ decisions and patients’ outcomes. Once patients experience the benefits of this technology, they will demand nothing less from their providers. Hundreds of thousands of physicians have already seen these benefits in their clinical practice.

[Except for those who
haven't - ed.]


And our government's called BP Energy Company cavalier?

I offer no additional comments.

Did EPIC CEO Judy Faulkner of Epic declare that ‘healthcare IT usability would be part of certification over her dead body?'

At the HisTALK blog 5/31/10 update, a site with thousands of readers involved in all aspects of health IT, the following anonymous (at this point) report appeared:

From Tabula Rosa: “Re: EMR usability. At one of the ONC Policy Committee meetings, [founder and CEO] Judy Faulkner of Epic supposedly declared that ‘usability would be part of certification over her dead body.’ I wonder if she has similar sentiments about making software accessible to people with disabilities?” Unverified. This inspired my new poll question – keep reading below.

Epic Systems Corporation is one of the largest health IT vendors in the U.S.

If this report is true, it would have very, very serious implications towards the healthcare IT industry's attitudes about the usability - and ultimately the safety - of its products.

The essential nature of usability and the relationship to safety is not an issue for debate - period. It was settled long ago in relation not only to IT, but also to devices and machinery that use IT. For instance, see the mid 1980's wisdom written for the U.S. Air Force on user interfaces at my eight part series on mission hostile health IT user experiences at http://tinyurl.com/hostileuserexper. Microsoft and other responsible IT vendors spend billions on usability research.

I think it incumbent of the U.S. Office of the National Coordinator for Health IT, and its leader Dr. David Blumenthal, to confirm or deny that such a statement was made, on or off-record, at an ONC policy committee meeting, and if it was made, its exact context.

If it was made, it would raise the following questions:

  • Would its utterer be saying this out of concern that their products have usability deficiencies that competitors do not, and that are not correctable in a short time frame?
  • How much concern would such a statement indicate for the complex jobs of physicians, nurses and other clinicians whose safe conduct of their medical obligations depends on health IT?
  • How much concern would such a statement imply towards the injured and dead bodies of patients affected by health IT of deficient usability?
  • Since the CEO sets the tone for their company and has the ultimate responsibility for its conduct (and its Board of Directors as well), would such a statement reflect willful negligence and perhaps criminal conduct?

The last question is pertinent, for if, say, the CEO of Boeing were to relate that "usability of the control systems of its aircraft would be an FAA certification requirement over his or her dead body", or the CEO of oil drilling companies said same about their instrumentation that helps avoid underwater blowouts, I believe it would rise to the level of criminally negligent conduct.

This is all the more pertinent to me, as my mother was just seriously injured by a medication error that resulted from an apparent inability to move a few kilobytes of correct medication data (about which she was asked to confirm in the ED at presentation) from ED to floor. End result - a cascade of resultant complex medical problems resulting in a life-threatening 4.5 cm intracerebellar hemorrhage and emergency craniotomy. I do not know if she will survive.

I had warned this hospital's CEO and Chief of the Medical Staff - in writing - of deficiencies in its EHR systems regarding physician-physician communications a little more than one month ago, in fact, explaining that in my expert opinion, patients might get harmed.

Little did I know my own mother would be that patient a few weeks later.

I am seriously wondering, in fact, if the average hospital has the gravitas and political and technologic maturity to truly implement health IT so that the technology is uniformly beneficial, instead of spontaneously harmful, to meet the needs of the grandiose plans for national health IT.

The lack of seriousness, petty political fights, and technological dyscompetence and incompetence I have noted in my 20 years in this field do not seem surmountable in any time frame I consider "soon."

Here seems to be the health IT industry and hospital MIS department view of healthcare IT, as some sort of game to be played for profit, power and political advantage:




Here is the reality of health IT dysfunction, as my mother is now cruelly experiencing:

Addendum May 31, 2010:

The comment thread at the bottom of HISTalk's Monday Morning Update 5/31/10 (from where the above EPIC CEO quote came) demonstrates numerous attitudes that give life to my concern that many uni-disciplinary, technology-focused HIT industry personnel may in fact be culturally and educationally unprepared, unwilling and/or unable to be collaborative, humane, safety-conscious members of the medical teams they are ostensibly hired to facilitate.
