Why non-medical amateurs need to be kept away from authority roles in health IT ... lest their ignorance kill people

This example of a disaster waiting to happen, in the form of an error-promoting CPOE, is a poster example of why the net of litigation needs to be cast far wider than just clinicians when EHR-related errors result in injury or death:


CPOE selection screen for crucial blood thinner, coumadin (Warfarin).  Click to enlarge.


This order entry screen, from a production system (of a vendor whose stock price has recently taken a dive) shows the following.  In all fairness, I do note it's unclear if the vendor or the customer's configuration "experts" were responsible for this:

COUMADIN (warfarin) tablet 2 mg Oral daily once.
CAUTION: Potential look-Alike or Sound-Alike medication - this product is COUMADIN

with similar entries for other doses.

Below and not indented as is the selection, where the clinician is liable not to look very carefully, is the helpful interpretation:  "warfarin (COUMADIN) Tablet 2 milligram Oral daily for 1 Times."

"Oral daily for 1 Times?"

This drug needs to be given daily, generally for a very long term.  Its effect on blood clotting varies for numerous reasons in an individual over time, and needs to be checked frequently via a blood test (International Normalized Ratio or INR) to ensure the level of effect is neither too little (which could result in clots) or too much (which could result in serious or fatal bleeding).

In this case, the clinician wanted Coumadin to be administered "daily", as in "each and every day", but this was the default - daily, but only once.  "Oral daily for 1 Times."

Brilliant!  

Daily Coumadin (i.e., daily EVERY DAY), the clinician related, could be ordered only with "painstaking difficulty."

"X mg Oral daily once" is an unimaginably absurd and bizarre dosing selection to have on a CPOE system for such a critical drug - or any drug.  "Daily - once?"  

It should not, and does not, take a rocket scientist to realize this selection could quite easily lull the busy clinician into believing they have selected a dose to be continued every day - i.e., "once daily" - as per the standard usage of this drug.

To order this drug for (true) daily administration, a user must find a "repeat" icon and click the number of days the drug is to be administered.  The "repeat" icon is not readily apparent amidst screen clutter.

For other drugs, the order choices are "## mg oral daily" or similar. 

This semantic and human-computer interaction ineptitude is truly a disaster waiting to happen, especially with the medical/nursing/trainee staff turnaround that goes on in hospitals, and with the reality that clinicians are working at various hospitals with different CPOE/EHR systems.

Is this some sort scheme to prevent endless-administration Coumadin errors when the drug is actually deliberately discontinued, I ask?  If so, it's ill-conceived and dangerous at best.

By way of further information, this drug is a common anticoagulant whose use is often protective of injurious or fatal blood clots that can cause strokes or death in people with common conditions such as atrial fibrillation or prosthetic heart valves:

Warfarin is used to decrease the tendency for thrombosis or as secondary prophylaxis (prevention of further episodes) in those individuals that have already formed a blood clot (thrombus). Warfarin treatment can help prevent formation of future blood clots and help reduce the risk of embolism (migration of a thrombus to a spot where it blocks blood supply to a vital organ).

The type of anticoagulation (clot formation inhibition) for which warfarin is best suited, is that in areas of slowly-running blood, such as in veins and the pooled blood behind artificial and natural valves, and pooled in dysfunctional cardiac atria. Thus, common clinical indications for warfarin use are atrial fibrillation, the presence of artificial heart valves, deep venous thrombosis, and pulmonary embolism (where the embolized clots first form in veins).

This is an example of the kinds of mission hostility (other equally bizarre examples presented here) that results when amateurs attempt to play doctor.

I add that this type of "errorgenicity" is inexcusable.  If patients suffer harm from this type of "feature", the net of liability needs to go further than just the clinician who was caught in a web of cybernetic clinical toxicity.

More EHR madness and another physician, a cardiologist and electrophysiologist, who also believes these should be considered medical devices.

From DrWes blog (excerpts, and emphases mine; see entire post at link below):

The Electronic Medical Record Should be Viewed as a Medical Device 
Apr. 30, 2012

This week I received a medical record from a large academic medical center somewhere in the United States (the details were are unimportant) that has one of these new pioneering EMR systems manufactured by $13 billion-dollar company, Cerner Corporation ... what I saw was one of the better examples of how EMRs are contributing to misinformation and confusion when health care is delivered.

I received a copy of an internal medicine consult that was performed on a patient at this outside hospital. I have extracted the "medications" portion of the internist's note exactly as it was displayed in the note below ... Needless to say, I was terrified at what the system had listed as the patient's medications:

In this example, we see multitudes of medications listed more than once. We see drugs of similar classes (antihistamines, beta blockers) on the same list. We see warfarin, one of our most dangerous drugs dispensed, without a dose included. We see what seems to be outpatient meds listed with inpatient meds, I'm not sure. Honestly, we really have no idea what medications are actually being taken from this list. And yet this list of medications is listed by the EMR as the patient's "Active Medications."


Med list (page 1).  Click to enlarge; see original post for part 2.


... What the heck have we created? 
Certainly, any capable physician who cares for patients would describe this medication list as worthless.

This "med list" is similar to the list I showed at part 4 of my multi-part series on the mission hostile user experience of most commercial EHR's, from yet another system, redrawn by me in redacting the vendor ID.  These lists reflect a mercantile computing person's view of a med list as an inventory of pills:

 Dr. Wes also asks:

... So how will we measure problems with EMRs? It seems industry representatives would rather not address these concerns. We should ask ourselves, is anyone thinking about this?

Yes, they are.  And we are spreading our thinking to one place where action might actually occur sooner rather than later:  to the Plaintiff's Bar.

Medical center has more than 6000 "issues" with Cerner CPOE system in four months - has patient harm resulted?

As I have written at Healthcare Renewal before, computerized physician order entry systems (CPOE's) are known to present risks to patients through induction of medical errors.

This technology is held out to be ready for national diffusion, right up to the POTUS. Per ONC director Blumenthal in the July 13, 2010 NEJM:

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.

Vendors deny major problems with their CPOE and other health IT products.

The true story is a bit more complex.

Fortunately, there are some medical centers who are open and honest about HIT problems. These medical centers seem a rarity. However, those that do share are actually conducting themselves in an honorable and mission-true manner, per Joint Commission Safety Standards, the ethics of the medical profession, and the expectations of the public. They should be commended.

One such example is Munson Medical Center in Michigan.

From the October 2010 "News for Physicians affiliated with Munson Medical Center" newsletter, a large medical center in Northern Michigan, about more than six thousand "issues" with their Cerner CPOE:

POE Program Continues to be Improved, Enhanced

The Provider Order Entry (POE) program continues to be improved. Since implementation in June [four months ago - ed.], more than 6,000 issues have been reported. Issues are defined as an aspect of the program not working as intended [does that include medication and treatment errors and 'near-misses'? - ed.], process issues [can these 'issues' kill? - ed.], education needs, or PowerPlan [Cerner - ed.] change requests.

About 600 of these remain open. Issues are prioritized by the POE Team and addressed according to existing standards.

One wonders how many of those 6,000, and how many of the 600 remaining "issues" fall into categories of "likely to cause patient harm in short term if uncorrected" or "may cause in patient harm in medium or long term."

I note that Cerner CPOE is not a new product, nor are similar products from other vendors also afflicted with long lists of "issues." That there could be more than 6,000 "issues" at a new site suggests deep rooted, severe problems with CPOE specifically and health IT design and implementation processes in general.

Did patient harm result here or at other CPOE sites (using products of any vendor, not just this one) that had hundreds or thousands of "issues"? We may never know.

That national rollout is mandated as if this technology were proven, safe, and plug and play is a scandal of UK NPfIT-like proportions.
