It’s Harder Than It Looks
MAKING THE CASE FOR CASE-BASED LEARNING
For sake of full disclosure, I was one of those guys. You know, the ones who wax poetic about how hard it is to teach our students how to do procedures. Let me tell you, teaching folks how to do epidurals on women in labor certainly takes its toll on the coronary arteries. It’ s true, I am amazing . . . I am great . . . I have nerves of steel. Yes, I could go on like this for hours . . . but you have heard it all before. But, it’ s again that time of year when our new students sit eagerly before us, full of hopes and dreams . . . and that harsh reality comes slamming home . . . it is a lot harder to teach beginning medical students “doctoring” than it looks.
A few years ago, I was asked to teach first-year medical and physician assistant students how to take a history and perform a basic physical exam. In my mind, I thought, “This should be easy . . . no big deal.” I won ’t have to do much more than show up. After all, I was the guy who wrote that amazing book on physical diagnosis. After all, I had been teaching medical students, residents, and fellows how to do highly technical (and dangerous, I might add) interventional pain management procedures since right after the Civil War. Seriously, it was no big deal I could do it in my sleep with one arm tied behind my back blah blah blah.
For those of you who have had the privilege of teaching “doctoring,” you already know what I am going to say next. It’s harder than it looks! Let me repeat this to disabuse any of you who, like me, didn’t get it the first time. It is harder than it looks! I only had to meet with my first-year medical and physician assistant students a couple of times to get it through my thick skull: It really is harder than it looks. In case you are wondering, the reason that our students look back at us with those blank, confused, bored, and ultimately dismissive looks is simple: They lack context. That’ s right, they lack the context to understand what we are talking about.
It’ s really that simple . . . or hard . . . depending on your point of view or stubbornness, as the case may be. To understand why context is king, you have to look only as far as something as basic as the Review of Systems. The Review of Systems is about as basic as it gets, yet why is it so perplexing to our students? Context. I guess it should come as no surprise to anyone that the student is completely lost when you talk about let’ s say the “constitutional” portion of the Review of Systems, without the context of what a specific constitutional finding, say a fever or chills, might mean to a patient who is suffering from the acute onset of headaches. If you tell the student that you need to ask about fever, chills, and the other “constitutional” stuff and you take it no further, you might as well be talking about the
