Essential Value
of Medical Informatics Expertise in High-Risk Areas: an Invasive Cardiology Example
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 MIS department was engaged to assist the cardiac
catheterization lab in this information technology need.
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.
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 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
a hostile tone that the MIS people "get out of our cath
lab!"
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 clinicians, used to 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.
An informaticist
was then hired as an "internal consultant" (instead of as leader,
itself perhaps symptomatic of a "control mentality" existing in this
organization's executive team), after a senior executive found out about the
existence of such specialized personnel. The informaticist
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 bizarre scenario, 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 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.
