Making the implicit, explicit – a core concept in clinical teaching

Learning in a work place such as general practice has its challenges. A student may give feedback that they feel the placement is a waste of time.  They sat in the corner of the consulting room observing the GP interact with many patients but did not feel they learnt anything.   A trainee may complain that their supervisor doesn’t seem to follow evidence-based guidelines in their management of patients.  It is a different learning context to the classroom and I have been thinking about this recently.

I have just attended the EURACT (European Academy of Teachers in General Practice/Family Medicine)  conference in Leuven, Belgium. It’s the first time I have been to this conference and, in fact, this is only the second of planned two yearly conferences. There were just over 200 attendees and this contrasted with the AMEE conference in Basel which had between three and four thousand participants. The other big difference is that AMEE caters for all those involved in medical (and other health) education and largely at the undergraduate level. That is a huge field.  EURACT was focussed specifically on teaching in general practice “in the real world” but it’s breadth lay in the diversity of countries represented, extending from Ireland to Turkey. I was the sole Australian and when queried about why I would attend a European conference I did liken it to Australia being in Eurovision!

I attended because I am currently involved in writing modules for a certificate in clinical teaching, geared specifically for GP supervisors of undergraduate students.

In at least three of the conference sessions I attended there was mention of making the implicit, explicit or the invisible, visible. This had already been an emerging theme as we developed the certificate modules.

It is described in the literature on learning theories (such as the cognitive apprenticeship model) where there is an emphasis on articulating what you are thinking.  We had discussed it at length when exploring how to teach clinical reasoning – a topic missing from many courses but one that is highlighted when supervisors later encounter trainees who appear to lack good clinical reasoning or fail exams because of this.  Clinical reasoning is a crucial skill for doctors (obviously) but there are nuances in the GP context.

At the conference the strategy of making the implicit, explicit was mentioned in several contexts – in relation to teaching both clinical examination and diagnostic skills and in the teaching of evidence-based medicine (EBM) in practice (rather than in a didactic series of lectures).  At the University it may be possible to didactically present content. The teachers may not necessarily be involved in the muddy waters of clinical practice (and may be dismissed as inhabiting the ivory towers of academia by those who perceive themselves to be at the coal face).  It is rarely so straightforward in practice.

We often claim that work-based learning is the most effective but it is also variable and unpredictable. The idea of making the implicit, explicit can be seen as a theoretical underpinning or as a strategy.  For instance, you have a clinician teacher who developed his or her skills during their training (in various ways) but these skills are applied (as experts do) almost automatically and unconsciously in the clinical situation. The underlying thinking or the way of putting the skills together does not seem obvious to the learner. Their consequent learning is laboured or hit and miss. The teacher’s application of their knowledge has also been modified by experience and context and it is a challenge for the learner to extract the principles from the wealth of detail in the clinical practice they are observing.  Thus it falls to the clinician teacher to articulate how they are thinking when puzzled by a diagnosis, to explain the complex influences that led them to prescribe a particular medication in this consultation or to justify their choice of examination or investigations at this point in the process.  It goes further than just listing the available evidence but puts it into context.  EBM is about applying evidence to the individual ‘s situation- but this is only realised in clinical practice, so students can make the most of this opportunity.  

How do we apply this in practice?  As an educator, remember to ask questions and expect the student to ask questions. Why do you think I did this?  Do you have any questions about what I just suggested?  What would you have done?  What is influencing my decision here?  Do others do it differently?  What is the latest on this according to what you are learning at University?

Get into the habit of asking yourself questions ie reflection.  Have I changed my management over time and why?  Am I up to date in this area?  In addition, it is the supervisor’s role to facilitate the learner to articulate their own thinking as they examine a patient or present a case. “I think I can guess why you did that but can you describe your thought processes that led you to it?”  Sometimes it is sufficient to be able to identify and describe the learning within the consultation so that it is recognised by the learner.

In the academic environment, clear principles and curricular content may be presented. In the real world of clinical practice we need to draw out the principles and curricular substance within  the complex human interactions – to make the implicit, explicit and to guide students on the path from novice to expert.

 

Teaching when you don’t know the answers

Fortunately it is often effective to use the perplexing case as a teaching tool and sometimes it is possible to have the patient as a partner in the teaching and learning process. It also gives the opportunity to treat the learner as a colleague.

This approach can be used for either medical students or registrars. Supervisors often call in registrars to see a “classic” rash and this is great in increasing clinical exposure.  Sometimes we are tempted to leap in with answers rather than leading the learner to work out the solution to a diagnostic or management dilemma.   However, if there isn’t yet an “answer”, there can be an even more valuable learning exercise.

In the past I have asked those finishing a gastro term for suggestions on abnormal LFTs or a student with a previous life as a physio for advice on musculoskeletal problems, but this is still seeking answers. The patient I have in mind is where we are still puzzled and are trying to work out how to proceed.  This brings in the opportunity to make clinical reasoning skills a bit more overt.  This calls to mind when I had  a patient with an itchy annular lesion that wasn’t quite “classic”(barely visible scale)  and was getting worse.  The registrar and I discussed the top-of-the-list differential diagnoses and the most useful investigation to do as the next step.  It raised the issue of tinea incognito (which skin scraping confirmed).

Sometimes you see a patient’s name on your session list with a medical student booked in also. You have gone a certain distance in the diagnostic process but all is not clear.  I might speak with the patient beforehand and ask them to be part of the learning process.  I guess this is more than just signing the consent form before they enter the room.  You might admit to the student that you still don’t have an answer so your “interrogation” of their history and examination is not an attempt to catch them out (or demonstrate your superior expertise).  When the patient has a skin problem, you might structure it by leaving the student to take a “dermatology history and examination” and return to ask them to present their findings (with the patient to comment as need be).  You can add anything they might have missed in the history (and discuss why it’s important) and also chat about how to describe things in “dermatological language”.   You might share your own diagnostic process so far (and this can be informative for the patient). You may lead the student to the next diagnostic step that you perhaps already have in mind.  With the patient gone you can put the learner on the spot a bit more with asking them to commit to (say) three differential diagnoses and  ask them to identify some questions that remain – for self-directed learning.  You can share online resources for instance if relevant (useful sites might be https://www.dermnetnz.org/    or  http://www.pcds.org.uk/ )or share brief stories of other cases if relevant.

I thought I would use this approach a couple of weeks ago but then the patient went off on holidays so I had to adapt. The patient had already given me permission to take a photo and use it to discuss with colleagues or for teaching. In fact she was happy for this to happen since we didn’t have a diagnosis as yet. It was on a nicely unidentifiable part of the body. The evening before the session I put the picture into a power point and structured the slides historically with the questions that arose as the case unfolded.  I put questions at appropriate points and printed out the half dozen slides. I  had also sent a question around my colleagues at the practice asking their opinion and one of them said it reminded her of an article she had just read in AFP on skin biopsies which I printed off and gave to the student to read later https://www.racgp.org.au/afp/2017/may/skin-biopsy-in-the-diagnosis-of-inflammatory-skin-disease/

The session had my usual collection of older complicated patients with multiple problems, some with diabetes, a couple of teenagers, a person with an unexpected result to explain etc. We took five minutes between patients and I suggested we pretend the patient was there and we worked through the printed case thus far.  We reasoned through it and I asked for suggestions.

This particular student was very knowledgeable and the diagnosis (revealed at biopsy later) was on their list of differentials. At the end of the session as they left they said “Oh, and thanks for the teaching session with the dermatology case. It was great.”  And I thought I was teaching the whole afternoon!  Amazing what a bit of structure does.
