Introduction
Gentlemen, what I want are Facts.... Facts alone are what is wanted in
life.
Dickens, Hard Times
Like journeymen in a skilled trade, radiology residents learn through an
apprenticeship composed mainly of on-the-job training, with smaller additional
components of independent study and formal instruction. As in technical
school, radiology apprentices are usually not expected to conduct original
investigation or to advance the field, but merely to assimilate an existing
body of knowledge and skills and become adept at applying that repertoire to
practical situations [1].
Operating in a technical mode, many of our residency programs treat
residents as empty vessels, as if the essential function of the residency
program were to pour knowledge and skills from full vessels (faculty) into
empty ones (residents). Our 4-year mission, we seem to think, is to fill up
those vessels with thousands and thousands of facts. The implicit message we
send the residents is this: "What you need to know is defined by what we
know. If we don't know it, you don't need to know it."
In many medical disciplines, including radiology, the technical model has
dominated residency programs for decades. It exhibits a number of advantages.
For one thing, such a program makes it relatively easy to specify what
trainees need to learn; namely, they need to learn what the faculty tells
them, or what their specialty's certification examinations cover. When
disputes arise over the validity or relevance of a particular point, one need
only repair to a textbook. Moreover, the technical approach makes it
relatively easy to determine whether a particular traineeor for that
matter, a whole residency programis doing a good job. One need merely
administer a standardized test and measure how thoroughly the trainees have
memorized the facts. Finally, this approach makes life relatively easy for
both the faculty and the residents. By relying on the technical model, both
are spared the more intense struggle of creative collaboration and mentorship
that characterizes graduate study in higher level academic disciplines, where
students are expected to do original work.
Error and Uncertainty
In technical schools, mistakes are dealt with as defects, because they
represent failures to adhere to established patterns of thought and practice.
The implicit message of this system is simple: there are only two types of
answers, right answers and wrong answers. Uncertainty is to be avoided at all
costs.
Yet a deeply ingrained aversion to uncertainty is nearly antithetical to
the creativity on which scientific and educational progress depends. Without a
high tolerance for uncertainty, it is impossible to suspend judgment, to
question the received view, to look at a problem from multiple perspectives,
and to create new approaches. By implicitly promoting the mindset of a
technical apprenticeship, many radiology residency programs undercut the
impulse to become a self-critical and creative contributor to the field
[2]. In short order, fact-laden
radiology review manuals become the residents' bibles.
Science
How do residents view science? Many express little or no enthusiasm for it.
This disinterest arises in part from the fact that the curriculum discourages
thinking like a researcher, and in part from the fact that many residents
receive no meaningful exposure to research at any point in their training
[3]. With the growing demands
on radiology programs to increase clinical through-put, we rely more and more
on residents for image interpretation; time for training in research has
become a luxury that many programs believe they can't afford. Over time, many
residents come to regard science as a received body of facts, a collection of
information, the sum total of the contents of all the radiology textbooks.
In fact, nothing could be further from the truth. Science is not a received
body of facts, but a struggle to understand, a determination to expose the
false and inadequate, and a thirst to find out what we don't know. Scientists
regard the information in textbooks not as their final goal, but as their
springboard to discovery. Instead of trying to cram residents full of
information, we should be trying to foster their curiosity, skepticism,
creativity, and willingness to make mistakes. Residency should be conceived as
an invitation to discovery in which it is not enough merely to know the right
answers; it is no less important that one be capable of posing the questions
that produced them.
Testing
If we wish to nurture the intellectual integrity of residents during
training, we must be prepared to stop our ears to the sirens of testability.
The current system of testing and the incentives based on it exert a powerful
influence both on how residents approach learning and on what they wish to
know. When residents believe that their success or failure will be defined
largely in terms of their scores on standardized examinations, they naturally
modify their activities to conform to those expectations. When they discover
that such examinations pay little heed to abilities such as critical thinking
and creativity, they naturally redirect their attention to those parameters
that the examinations test best; namely, the memorization of facts. In their
quest to master facts, however, they become slaves to convention and
relinquish their capacity to play a meaningful role in the pursuit of
understanding.
Radiology residency programs should strive to create fertile minds. The
noninterpretive skills program of the Association of Program Directors in
Radiology and the American College of Radiology is an important step in this
regard, but more work remains to be done
[4,5,6,7,8].
We cannot afford to regard with complacency the fact that many of the most
important lessons radiology residents should be learning are underrepresented
in the curriculum precisely because it is difficult for the American Board of
Radiology to figure out how to test residents regarding the lessons
learned.
Facts are fine, but only to a point
[9]. Beyond memorizing facts,
residents need to be encouraged to question what constitutes a fact, where
facts come from, and why some facts are deemed important and others are not.
The tail of testability must never be allowed to wag the dog of what's really
worth knowing. Cultivation of the capacity to distinguish what's really worth
knowing from what isn't should be a primary mission of every radiology
residency program.
Homogenization
Radiology is fortunate to attract many bright people into its fold. But
what starts happening to them as soon as they arrive? Do they become more
interesting people as a result of their residency experience? Do they become
more inquisitive, more creative, or wiser? Or, by inviting them to bury their
noses for 4 years in radiology review manuals, are we inviting them to become
less interesting, increasingly short-sighted, and more one-dimensional?
Many of our residency programs seem to be modeled after the dairy industry,
where homogenization is king. If radiology is to flourish, however, it is
vital that we encourage a diversity of perspectives. We should seek out people
who can bring something different to the field, provide them ample
opportunities to explore and develop interdisciplinary interests, and design
our organizations to take advantage of their distinctive abilities to
contribute.
History
How can radiology residency programs foster the capacity to discern what's
really worth knowing and play a creative role in its pursuit? Oddly enough, a
significant part of the answer lies in an unexpected place. If radiology
residents are to achieve the larger perspective on the field necessary for
self-reflection and creativity, there is no better place to begin than
history, the study of how things came to be the way they are.
It is in the study of a discipline's history that some of the most crucial
lessons become apparent: the realization that things haven't always been this
way, that today's facts weren't ready at hand in yesterday's textbooks, that
such facts were born of questioning, that some of yesterday's lines of
questioning led nowhere, and that it was only because skeptical people asked
questions, rather than merely memorizing what they were told, that we are
where we are today. Far from being ignored, as is so commonly the case in
residency programs today, the history of radiology should become an essential
ingredient in residency training, and national organizations should make the
development of an intellectually rigorous curriculum of radiology history a
high priority.
Professionalism
Radiology programs should foster in both residents and faculty a sense of
intellectual excitement and encourage them to approach clinical practice with
equal doses of skepticism and creativity. Far from undermining individual
programs or the profession as a whole, a skeptical and creative radiologist is
their greatest ally. Only through the efforts of such people will we manage to
winnow the wheat from the chaff, sort out what about the "facts"
is true from what isn't, and propel ourselves beyond the modest boundaries of
what we think we know today.
Confronted with such arguments, some program directors may respond that
there is no time in the curriculum to address such noble objectives as
critical thinking and creativity. As the volume of radiology information
continues to expand exponentially, there isn't even sufficient time to teach
residents all the basic facts about radiology. Far from contesting this
statement, sober analysts of residency training should lend their hardiest
assent.
There isn't enough time in the curriculum for residency programs to teach
all the basic facts about radiology. In fact, there hasn't been for a long
time. The question is, what is the appropriate response to this situation?
Shall we simply lengthen the course of training from 4 years to 5? Shall we
simply peddle ever harder in the same old direction, only to fall further and
further behind? Or shall we rethink what the radiology residency should be all
about in the first place, spending a bit less time on what to know
(information), and a bit more on how to know, and why?
Practical Approaches
At a practical level, what can residency programs do to achieve these
objectives? Here are some suggestions for departments with the capability to
implement them:
- First, radiology departments should provide their residents with regular
conferences devoted to ongoing research, accompanied by an invitation to
participate. If there is no research in radiology, then researchers in other
disciplines, with whom radiologists might collaborate, should be invited to
present their research, and both faculty and residents should attend.
- Second, residents should be encouraged to engage in research during their
training, with time and resources set aside for that purpose
[10]. Appropriate mentorship
should be provided, and faculty should be evaluated in part in terms of the
quality of research mentorship they provide. Resident participation in
research should be acknowledged and rewarded.
- Third, residents should be given regular opportunities to present and
critique one another's projects. Residents who are not involved in research
should develop educational presentations that make them local experts in a
specific aspect of radiology.
- Fourth, a journal club, in which residents are expected to read and
critique the primary radiology literature, should become a regular part of
every radiology residency program
[11]. Occasional formal
debates over such topics as "The Best Test for Pulmonary
Embolism," "The Use of the Term `Infiltrate' in Chest
Imaging," and "Who Should Control Vascular Sonography?"
should become a part of the curriculum.
- Fifth, critical thinking should become a permanent feature of teaching at
the view station. For example, faculty and residents should operate in a
culture that encourages them, within limits, to challenge one another's
assertions. Residents should be praised less for the facts they recite and
more for the questions they raise.
- Sixth, research in nontraditional fields should be encouraged. These fields
would include, but not be limited to, education, history, management, and
health services research [12].
Such studies foster a wider perspective on the field and promote the
formulation of new questions about it. Departments should provide time and
resources to help committed residents find funding for graduate-level training
in such fields.
- Seventh, radiology programs should encourage faculty to play an active
service role in their departments, schools, and communities, and encourage
residents to emulate the faculty. Both should strive to flourish not only as
radiologists, but as human beings and citizens. Service achievements should be
formally recognized by the department.
- Finally, these and other innovations in residency training should replace,
not displace, some of the fact-based instruction in today's training programs.
Residents already spend more than enough time memorizing information, and we
cannot simply load more expectations on an already overstuffed curriculum. The
goal here is to devote time and energy to the creation and development of new
cognitive perspectives, and that requires time to think.
Conclusion
If radiology is to flourish, it is imperative that we reexamine our
residency programs in light of a larger vision of radiology excellence, one
that esteems originality alongside authority, imagination alongside
memorization, and vision alongside detection. We must focus less on the
capacity to collect information, and more on the intellectual habits of mind
we engender. We must place first in our deliberations the question,
"What do we really need to learn?" and accord the question,
"What can we test?" second place. We must be willing to make
mistakes, and dedicated to learning from them. We must develop residents who
address the question, "What have you amounted to?" not in terms of
what they have managed to accumulate, but in terms of what they have
contributed to their profession and their society. If we are to achieve these
goals, we must prepare our residency programs for graduation from technical
school.
