TIPS FOR TEACHING CLINICAL REASONING Clinician teachers often struggle with teaching clinical reasoning. Three different methods for teaching clinical reasoning will be explored with a focus on effective questioning. Preceptors frequently use questions as a method of teaching in the clinical setting. However, the nature of questioning can have a significant impact on what is taught in the clinical context. By developing skill in questioning, clinician educators can become more effective at teaching clinical reasoning and decision making. In this workshop, participants will use case examples, guided exercises and group discussion, to analyze and develop their questioning skills to enhance the teaching of clinical reasoning and clinical decision making. 1. At the conclusion of this workshop, participants will be able to list three different techniques in teaching clinical reasoning. 2.) At the conclusion of this workshop, participants will have better tools in useing questioning effectively to guide learners in the development of clinical reasoning skills.

• Dual Processing model of clinical reasoning:• Rapid intuitive component (Type 1)

• Based on illness scripts and heuristics• Slower, logical and analytical component (Type 2)

• When a heuristic is not easily applied

• Diagnostic errors• Failure of a heuristic is referred to as cognitive bias

• Recent literature review, suggests that both thinking processes contribute to errors

• The suggestion that errors occur because of cognitive biases in Type 1 thinking is simplistic

• The most consistent evidence around diagnostic error is deficient clinical knowledge

• Allow the learner to watch you problem solve and then unpack your thinking with the learner

• Critical thinking arrow (or Bayesian thinking)

• Socratic questioning to develop clinical reasoning

Unpacking your thinking

• Heuristics or illness scripts are unconscious pathways that clinicians use to travel a diagnostic path, based on real patient experience

• Learners have not developed these because o their lack of patient experience

• Unpacking these by working through the discriminators within a clinical problem helps the learner develop his own illness scripts

• Pretest odds for a disease x likelihood ratio = post test odds for a disease

• Pretest probability based on prevalence can often be found in the literature (often as various risk scores)

• Likelihood ratios can be found in other literature such as ACP PIER, Dynamed or JAMA’s Rational Clinical Exam Series

• Searching these out can be a student’s job and can help them understand the rationale

However, you can actually use evidenced based medicine and the math

The process can allow the transformation of a statement such as …

“The negative d‐dimer makes pulmonary embolism unlikely in this patient”

To …

“The negative d‐dimer in our patient with a pre‐test probability of 37.5% based on the Well’s score reduces her post‐test probability to about 5% essentially ruling out pulmonary embolism”

Using effective questions

• To assess knowledge

• To assess understanding

• To assess thought processes

• To engage learners

• To determine a starting point

• To teach all of the above

Why do we question?

• Before the question, think about the purpose of the question

• Is your question…• Learner centred?

• Knowledge centred?

• Assessment centred?

• Know what you are trying to accomplish with the question

How can questions promote clinical reasoning at different levels of training?

• Questions for clarification of thinking

• Why do you say that?  Could you explain further?

• Questions that challenge and probe assumptions

• Is this always the case?  What assumptions are you making?

• Questions that probe rationale, reason and evidence

• Is there reason to doubt this evidence?

What can we learn from Socrates?  Six types of questions for six different purposes:

• Questions about about alternative viewpoints and perspectives

• Can you see another way?  What is the counter‐argument?

• Questions that probe implications and consequences

• What if…. ?

• Questions about the question

• Why do you think I asked that question?

Six types of questions for six different purposes:

• Divergent versus convergent

• What if? 

• Compare and contrast

• For and against

How might we ask deeper questions?

What makes these different or distinct?

What are you trying to accomplish with each level of learner?

How to probe clinical reasoning with different learners?

• Minimize knowledge questions

• Questions to unpack the problem itself

• Focus on justification:• What speaks for…

• What speaks against …

• Suggest reading around a “presentation” rather than reading around a patient:  compare and contrast

• Provide feedback on interpretive summaries:• What are you ruling out?

• What are the pertinent negatives?

• Prompt to think aloud… explain

• Probe alternative scenarios, highlighting key features

• Justify decisions and expected response to management

Tips and Tricks; Mid‐Level Learners

• Identify a few Socratic questions that you like and keep them in your tool box

• Be explicit about why your are probing

• Be explicit about your own thinking process

• Push learners to consider

Tips and Tricks; Senior Learners

Break into three groups.  We have three students here (junior learners) who each have a case to present.  Within your groups discuss and plan your questions to the students as effective Socratic questions.
