Essential Value
of Medical Informatics Expertise in High-Risk Areas: an Invasive Cardiology
Example
This is a story about how a medical
informatics professional moved a failed project to success via reliance on fundamental
principles of medical informatics and clinical medicine itself.
The chief and clinical staff of a busy
invasive cardiology (cardiac catheterization) lab at a large American tertiary
care hospital, responsible for a significant percentage of the hospital's
revenues, desired a data collection system to improve performance and outcomes,
perform benchmarking, reduce dictation, increase efficiency of clinical
communications, and end expensive inventory spoilage or risky shortages.
The hospital's business-computing department (i.e., management information systems or MIS) was engaged to assist the cardiac catheterization lab in this
information technology need. This
department’s clinical expertise was nil.
From the very start, the project was poorly
managed by MIS and by senior hospital executives.
The MIS deparment spent almost two years
going through analysis, market investigation, K-T decision grids, and other
business "process" before deciding on a product to purchase. What
they were doing during this time is unclear, as there are very few vendors
offering products for this environment. In-house development was ruled out by
MIS as unnecessary and not consistent with an MIS policy of "turnkey
solutions only," despite several senior cardiologists feeling that
customization would be critical. Such one shoe fits all, business
computing-oriented thinking is symptomatic of a lack of understanding of
clinical medicine that's often found in healthcare MIS departments.
After purchase, the vendor product sat
unused for almost a year before operationalization was considered by MIS. When
it was finally decided to implement the package, gross underestimation of the
resources needed resulted in only 0.75 FTE's assigned. Even worse, the MIS
person chosen had no experience working in tough, high-volume, critical care
areas. The project was, in fact, doomed
to fail even before it even got off the ground.
A Steering Committee was initiated, led by a
new, competent cardiac administrator who was unfamiliar with information technology.
It soon became apparent that the MIS personnel did not understand the clinical
environment and culture of a cardiac catheterization laboratory. MIS was
adamant that the vendor product should not be modified, an "appliance
operator" mentality, even though the clinicians wanted the data and
workflow components of the package to be adjusted to their busy clinical
environment and customs (rather than the other way around).
Conflicts began. The MIS department began to
blame the physicians for being "non-cooperative" with them, stubborn,
unable to finalize decisions about the package, and responsible for lack of
project progress. The cardiac administrator was blamed by senior officials for
"not controlling the doctors", representative of this organization's
somewhat unreasonable attitudes towards its lifeblood, its clinicians.
(Unfortunately, to use a medical metaphor, while this genre of negative
behavior by a healthcare organization towards its clinicians may "feel
good" to executives in the short term, in the long term the consequences
are usually deleterious to organizational health.) MIS insisted that the
cardiac administrator take "ownership" for the project, and assume
the role of clinical champion. The cardiac administrator tried to understand the
issues, but without expertise in information technology was highly dependent on
the MIS personnel for guidance on any technical issue. MIS itself could not
provide significant guidance as they were in over their heads in such a
clinical setting.
The clinicians began to realize that MIS had
greatly understaffed the project, and that MIS resources, skills, and
understanding of the environment were inadequate for the job. Further, their
requests for MIS to perform customizations of the application to match their
culture and environment were met with jargon-heavy reasons why it
"couldn't be done".
The MIS department continued with its "template
delay, false-start, peek-a-boo, tag-you're-it" games (as the
administrator described it) with the doctors and cardiac administrator. As a
result, the attempted install in the cath lab went so poorly, and was so
misaligned with needs, expectations, work flow, and the tremendous patient
responsibilities, that the demoralized and frustrated cath lab staff demanded
in overtly hostile tones that the MIS people "get out of our cath
lab."
In a common hospital IT politics ploy, blame
for the project paralysis and failure was shifted by MIS to the cardiac
administrator and clinicians, using language about 'process', 'ownership',
'nurturing', 'mentoring', 'feelings', and other impressive-sounding but shallow
and almost mystical puffery and rhetoric. This made the invasive
cardiology clinicians, with a culture characterized by directness and action,
even angrier.
An outside consultant was brought in for
several days, but could not resolve the difficulties between MIS and the
clinical staff.
A medical informaticist was then hired,
albeit as an "internal consultant” to the MIS department and lacking
executive presence and direct control of resources, after a senior executive
found out about the existence of such specialized personnel. (This organizational structural choice
itself was perhaps symptomatic of the
problems that led to the project failure, that is, an inversion of essential
healthcare IT leadership roles whereby business IT personnel operate far
outside their competencies.)
The informaticist first asked to see what
had been installed in the cath lab by MIS. The informaticist found workstations
running the application under Windows 3.1, an unreliable platform especially
unsuited for critical care environments, because "Windows NT and other
OS's such as UNIX were not supported by MIS." When shown a short demo of
data entry by a nurse after a cardiac cath case, the workstation crashed,
displayed a "general protection fault" error and hexadecimal
debugging data. It had to be rebooted, with resultant time and data loss.
The informaticist asked the nurse about the
crash and was told it happened frequently, up to several times per day per
workstation. When the informaticist asked if MIS had requested a detailed log
be kept of the crashes and error messages to help resolve the problem, the
answer was no. MIS felt diagnosis and repair was the vendor's responsibility.
When the informaticist asked the nurse exactly what had been explained to
clinicians about the crashes, the nurse replied that cath lab staff had been
told by MIS "don't worry about it, you can't understand it, we'll make
it better."
The informaticist remembered, from medical
school and residency, being told never to say such a thing to patients as it
was considered inappropriate and too paternalistic in the modern age of
medicine, especially with the elderly. This was an ironic and somewhat perverse
scenario for a critical care area, the informaticist thought.
The informaticist set out to correct the
problems, although the path ahead proved challenging even with informatics
skills. Workstations were asked to be changed to NT to ensure reliability. The
informaticist was first told that the application would probably not run under
NT, and that it also needed "RAID disks" (an intimidating buzzword to
must physicians) to run. The informaticist replied that RAID, a hardware-based
continuity and disaster recovery measure, was an operating system issue, not an
application issue, and that testing the application under NT would be easy.
Testing would end the need for speculation and debate, he also said. The
informaticist requested that two ordinary business PC's be set up in a test
environment on a table, one PC to run the server, and the other to run the
client under NT to test compatibility.
Upon realizing that this doctor was
technically knowledgeable, MIS moved the production application to NT in a few
days and thereafter it ran quite reliably. Under the informaticist's
insistence, against political resistance from MIS and operations who seemed
more concerned with appearances and "process" then with supporting
the cardiologists ("results"), the staffing was increased. Four had
been requested, and a compromise of three was reached. The informaticist was
able to hire a new MIS manager based on the informaticist's beliefs about
proper abilities, skill set, insights, and personality fit (e.g., a
"can-do, when do you want it?" attitude) in the dynamic cath lab
environment. This new manager had leeway to act independently to a large degree
from the corporate MIS department. The new MIS staff in the cath lab were able
to function as a decentralized, more flexible, local "island" of MIS
support for the cardiologists.
The informaticist first created a
collaborative and participatory work environment between the new MIS
cath lab personnel, the cardiac administrator, and the cardiologists, a
non-traditional methodology in MIS but crucial for clinical computing
settings (see Participatory
Design of Information Systems in Healthcare, Sjoberg C, Timpka T: Journal
of the Amer. Medical Informatics Assoc. 1998;2:177-183). A highly user-centric, iterative and
incremental development process was also instituted, which was at significant
variance to the traditional designer-centric “systems lifecycle” methodologies
traditionally employed by MIS. This
created considerable opposition by the MIS leadership, who seemed to view such
an approach as some type of sacrilege.
Such a belief, even in the face of years of failure, appeared to the
informaticist to be dogmatic to the point of religious conviction, or perhaps
worse. (Einstein on insanity: doing the same thing over and over again and
expecting different results.) A table
from Kling’s work on social informatics outlining the profound differences
between user-centric (“social view”) and designer-centric ideologies is here.
Next, the informaticist jettisoned the
traditional MIS approach of viewing a person's skills in using a specific
database application (e.g., Oracle) as a critical factor. The informaticist
identified as crucial the data modeling process for the cardiologist's needs.
This process has very little to do with software or computer science and
much to do with medical informatics. The finest technical expert in the
world in database development systems such as Oracle, client-server tools, etc.
is not very useful in such a function, since it is a high-level cognitive
function requiring clinical experience combined with medical data modeling expertise,
not computer or MIS expertise. The lack of recognition of the need to
partition strategic, high-level, cognitive informatics functions such as
healthcare data modeling from more mundane, low-level programming and
implementation tasks in clinical projects inhibits progress in healthcare and
biomedical IT.
It is with amazement that informaticists
such as the one in this story observe a blindness to this issue in biomedicine, including healthcare and the pharmaceutical
industry. The highest levels of informatics expertise should be sought
for any clinical initiative in busy clinical settings. In such settings, the
data development and customization process (a largely cognitive process
requiring extensive cross-domain experience) is an essential competence.
Once the critical cardiology data set and
data definition issues were on the mend with the informaticist's expert
assistance, the group was then able in a flexible, iterative manner to
customize the application data set and work flow components, and evaluate and
modify prototypes to zero in relatively quickly on a usable system. As a result, within several months regular
and reliable data collection and reporting had begun. In fact, the cath lab
staff began to get more involved in the customization process and the designing
of reports, and started to find the process intellectually challenging,
educational, and sometimes even fun.
Perhaps even more importantly, the
informaticist re-framed this project from one that could be perceived solely as
a negative "report-card" system about the cardiologists, to one that
would enable them to meet their own data needs and interests (e.g., for
research, domain-specific and new-device specialty areas, education, and other
topics). In doing so, the standard vendor-supplied package was only used as a
'vehicle' or starting point for the project, while dataset customizations
almost completely replaced the supplied vendor "internals". In
modeling the data of such a complex field in an optimal manner, the value of
the medical informatics discipline was very apparent.
Further, in operationalizing the system, the
informaticist made sure that a large degree of effort went into creating tools
to allow replacement of dictation, often a time-consuming process in invasive
cardiology, with a computer-generated case report. A very creative,
intelligent, computer science-minded programmer was carefully selected by the
informaticist to code the tools to create this capability. (The informaticist
here did not believe all programmers were created equal. As author Bob Lewis
points out in his book IS Survival Guide, Sams Publishing, 1999, p. 247,
three decades ago Harold Sackman researched the performance gap between
programmers. He found that the best ones were able to write programs 16 times
faster and debug then 28 times faster than those created by "average"
programmers, and when they were done their programs were six times more compact
and ran five times faster.) In a field as critical and complex as medicine, the
need for star performers is especially acute. This is hard to detect from a
resume. Informaticists who know both medicine and computing are often
especially good at identifying such programmer qualities, for example through
interviews.
Medical Records and transcription were also
strongly involved to enhance the cardiology computer system so that addendums,
if needed, could be flexibly dictated and added to the computer-generated
report on a section-by-section basis. Another area requiring significant effort
was automation for FAXing computer-generated reports on a timely basis to
referring clinicians and to electronically send reports to a central clinical
data repository for viewing at workstations in the medical center. This
"value added" approach to the project, strongly supported by the
cardiac administrator, proved crucial. It helped win physician support, since
it had the potential to save them significant time and labor while increasing
their accuracy and timely communications with referring colleagues.
The cardiac administrator, an extremely
capable and forward-thinking individual, learned a lot about medical
informatics and its value as a specialty, and many fine points about the
innocuous-sounding but unprecedentedly difficult task of defining precise,
fine-grained data to model an area as complex as invasive cardiology.
Unfortunately, in the opinion of the informaticist, the cardiac administrator
had become somewhat of a "scapegoat" for deficiencies of MIS and
senior executives in understanding clinical computing issues, and had lost a
bonus (and much peace of mind) as part of the lesson.
Postscript:
This heart center information system in its first two years of operation has
allowed this organization to save well over a million dollars in cath lab
operating costs, through stronger contracting, efficient equipment stocking and
utilization, etc.
Despite this, in an unfortunate example of
the suboptimal management that can result from unqualified decisionmaking in a
discipline as complex as healthcare computing, the senior executive assigned to
oversee both clinical operations and IT (despite lack of a background in IT)
now refuses to allow the chief of cardiology at this hospital to sit on the
organization's strategic information technology committee because the cardiologist
was felt to be aggressive and uncooperative (i.e., he thinks critically and
does not simply follow orders from the non-medical executive in question).
This exclusionary decision was made despite
the cardiologist's now probably being the most informatics-savvy in the
organization after intensive collaboration with the informaticist, who has
since moved on. This has once again infuriated the cardiology staff, who are
one of the largest revenue-generators for the organization amidst a sea of
potential competitors and declining revenues due to recent government
regulation cutting Medicare reimbursement (Balanced Budget Act). This type of
executive behavior should not be tolerated in hospitals.
Further, after years of being non-helpful to
this project, the same senior executive told other executives he "does not
see the value of the data", that the informaticist was "way out
there", and that the physicians are wasting money. This executive clearly
has both feet firmly planted in the Stone Age. As was recently observed in a
book about business practices, only those interested in the future build tools.
Whatever they might say, those who build few tools are not interested in the
future ("Building Wealth", Lester C. Thurow, HarperCollins Publishers,
1999).
This senior executive's opinions flew in the
face of an evaluation by invasive cardiology experts of national prominence. These experts rated the data project
"extremely important" and "an exceptional initiative"
during an independent evaluation of the facilities, requested by the
cardiac administrator for performance improvement purposes.
Those truly interested in improving
healthcare and reducing medical errors must critically evaluate the
obsolete, defective organizational structures that allow medically and
technologically-unknowledgeable persons to domineer qualified, competent
professionals on such data initiatives.
This story illustrates one danger to
clinicians and to patient care of permitting non-clinician business personnel
to take charge of clinical matters. The business personnel, often more
politically-savvy, may then engage in behaviors to call attention away from
deficiencies and shift blame for problems onto the clinicians. Clinicians must
stand up for progressive and constructive behaviors from management on clinical
information technology in the service of patients.
It should be noted that invasive
cardiologists and other such subspecialists are necessarily quite tough. As one
of my mentors, Dr. Victor P. Satinsky (inventor of the Satinsky clamp used in
cardiac surgery, among many other things) used to say about his tough training
programs, "If you don't like it, don't come." MIS personnel
and executives who are unqualified or uncomfortable with the rigor required in
such demanding clinical environments should find positions elsewhere, in
simpler settings, rather than engage in politics that obstructs technology used
to improve patient care.
Finally, in an example of the “Peter
Principle” running amok, the bright cardiac services manager decided to leave
the organization after being passed up for promotion, while those who had
impaired this project and numerous other projects through illogical thinking,
clinging to the past, and various other flavors of mismanagement (at great
waste of money) received generous promotions.
It is clear this organization still has
much to learn from medical informatics.
