White CB, Thomas AM. Students
Assigned to Community Practices for Their Pediatric Clerkship Perform as Well
or Better on Written Examinations As Students Assigned to Academic
Medical Centers. Teaching and Learning in Medicine. 2004; 16(3):250 - 254 Reviewed
by Bruce Morgenstern, Mayo School of Medicine In another paper
by a COMSEP member addressing the impact of the clinical experience of students
on their performance on written examinations, Chris White of MCG, along with Andria
Thomas from the Department of Family Medicine, evaluated the cumulative experience
of students over 5 years. They report that of the 830 students, the 173 students
who were at Community Practice Sites (CPS) did at least as well, if not better
than those who were at Academic Medical Centers (AMC). The NBME subject examination
scores did not differ. CPS students did better on an in-house MCQ type exam. They
also had a statistically better clinical grade (but I wonder if there is a meaningful
difference between 90.3 and 88.9?). Students at CPS saw many more patients (167
vs. 71). Comment: In an era in which the LCME has created a new emphasis
on "numbers and kinds" of patients, this paper adds meaningfully to
our data set. The student results at MCG are not dissimilar to results seen in
Nebraska. The results do differ from data reported in surgical clerkships, and
at least one other Pediatrics site. Before we place too much emphasis
on the parts of this study, which imply that students at CPS did better, we need
to look at those outcomes. White and Thomas argue well that the clinical grade
is not a meaningful tool, given how subjective clinical grades often are. They
do not spend much time letting the reader know much about their in house exam.
Is it reliable? Is it valid? Is there a pro-ambulatory bias to the exam? Perhaps
they have sufficient data to analyze their exam to see if the differences are
real. Despite these weaknesses, it is clear that students in different sites do
no worse. This adds to the questions that underlie the move of the LCME to "numbers
and kinds." Is there a dose-response effect to clinical education? Is there
some useful and valid measure of "equivalence" between clinical sites
in clerkship? Certainly, the MCG students seem to have disparate experiences (as
did those in Nebraska), but they seem to be able to test out the same. Perhaps
it's true, our students are chosen to be able to succeed despite us. We have an
important need to continue investigations along the lines of this paper. (Bruce
raises good questions about the evaluation data we use. I know that many of us
have a less than accepting response to the LCME requirements. Why is diversity
sometimes a good thing, but not acceptable at other times? Since the LCME standard
isn't likely to go away, and we have several studies that suggest that diverse
exposures do not have major impact on our measured outcomes, I'd like to pose
a different question. What was similar in the various experiences that resulted
in similar outcomes? Isn't that what we should quantify and use as our "numbers
and types?" Maybe it is because we know that pediatrics can be taught during
interactions with a variety of patients and diagnoses, that we have created systems
that allow students to learn the basics of pediatrics regardless of the type and
number of patients they see. Can you think of other groupings that will meet the
needs of the LCME and the experiences of your students? I think that the studies
may help us look at things from a different perspective and create a solution
that helps us train great doctors. Karen Marcdante) |
