Subject: [Implementation] - New Book on EHR Usability - "Better
EHR: Usability, Workflow, and Cognitive Support in Electronic Health
Records"
Dear Colleagues,
We
are pleased to announce the availability of a free new book from the
ONC supported SHARPC project: "Better EHR: Usability, Workflow, and
Cognitive Support in Electronic Health Records".
The electronic versions (both pdf and iBook) are freely available to the public at the following link:
https://sbmi.uth.edu/nccd/better-ehr/
First, this book appears to be a very good resource at understanding
issues related to EHR usability. I particularly like the discussion of
cognitive issues.
However, this book also holds messages about the state of the industry
and the issue of regulation vs. no regulation, and impairment of
innovation:
I think it axiomatic that user-centered
design (UCD) is a key area for innovation, especially in life-critical
software like clinical IT. (I would opine that UCD is actually
critical to safety and efficacy of these sophisticated information systems in a sociotechnically complex setting.)
I think it indisputable that the health IT industry has been largely unregulated
for most of its existence, in the manner of other healthcare sectors
such as pharma and traditional medical devices.
Yet, even in the absence of regulation, the book authors found this, per
Section 5 - EHR Vendor Usability Practices:
a) A research team of human factors, clinician/human factors, and clinician/informatics experts visited eleven EHR vendors and conducted semi-structured interviews about their UCD processes. "Process" was defined as any series of actions that iteratively incorporated user feedback throughout the design and development of an EHR system. Some vendors developed their own UCD processes while others followed published processes, such as ISO or NIST guidelines.
Vendor recruitment. Eleven vendors based on market position and type of knowledge that might be gained were recruited for a representative sample (Table 1). Vendors received no compensation and were ensured anonymity.
and
b) RESULTS
Vendors generally fell into one of three UCD implementation categories:
Well-developed UCD: These vendors had a refined UCD process, including infrastructure and the expertise to study user requirements, an iterative design process, formative and summative testing. Importantly, these vendors developed efficient means of integrating design within the rigorous software development schedules common to the industry, such as maintaining a a network of test participants and remote testing capabilities. Vendors typically employed an extensive usability staff.
Basic UCD: These vendors understood the importance of UCD and were working toward developing and refining UCD processes to meet their needs. These vendors typically employed few usability experts and faced resource constraints making it difficult to develop a rigorous UCD process.
Misconceptions of UCD: These vendors did not have a UCD process in place and generally misunderstood the concept, in many cases believing that responding to user feature requests or complaints constituted UCD. These vendors generally did not have human factors/usability experts on staff. Leadership often held little appreciation for usability.
About a third of our vendor sample fell equally into each category.
In other words, a third of health IT sellers lacked the resources to do an adequate job of UCD and testing; and a third
did not even understand the concept.
Let me reiterate:
In an unregulated life-critical industry, a third of
these sampled sellers thought 'responding to user feature requests or
complaints constituted UCD'.
And another third neglected UCD due to a 'lack of resources'.
I find that nothing short of
remarkable.
I opine that this is
only possible in healthcare in an unregulated healthcare sector.
Regulation, for example, that enforced good design practices and good manufacturing practices (GMP's) could, it follows,
actually improve clinical IT innovation considering the
observations found by these authors, through ensuring those without the
resources either found them or removed themselves from the marketplace,
and by making sure those sellers that did not understand
such a
fundamental concept either became experts it UCD, or also left the marketplace.
I can only wonder in what other fundamental(s) other sellers are
lacking, hampering innovation, that could be improved through
regulation.
As a final point, arguments that regulation hampers
innovation seems to assume a fundamental level of competency and good
practices to start with among those to be freed from regulation. In this
case, that turns our to be an incorrect assumption.
As a radio amateur, I often use the term "health IT amateurs" to
describe persons and organizations who should not be in leadership roles
in health IT, just as I, as a radio amateur, should not be (and would
not want to be) in a leadership role in a mission-critical
telecommunications project.
I think that, inadvertently, the writers of this book section
gave real meaning to my term "health IT amateurs." User centered design
is not a post-accident or post-mortem activity.

12/4/2014 Addendum:
I should add that in the terminology of IT, "we don't have enough resources" - a line I've heard numerous times in my CMIO and other IT-related leadership roles - often meant: we don't want to do extra work, to reduce our profits (or miss our budget targets), or hire someone who actually knows what they're doing because we don't really think that the expertise/tasks in question are really that important.
In other cases, the expertise is present. but when those experts opine an EHR product will kill people if released, they find the expert 'redundant', e.g.,
http://cci.drexel.edu/faculty/ssilverstein/cases/?loc=cases&sloc=lawsuit.
Put in more colloquial terms, this is a slovenly industry that has always made me uncomfortable, perhaps in part due to my experience having been a medical safety manager in public transit (
SEPTA in Philadelphia), where lapses in basic safety processes could, and did, result in bloody train wrecks.
Perhaps some whose sole experience with indolence and incompetence-driven catastrophe has been in discussions over coffee in faculty lounges cannot appreciate that viewpoint.
Academic organizations like AMIA could do, and could have done, a whole lot more to help reform this industry, years ago.
