The phenomenal strides in every branch of scientific medicine have tended to overload it with detail. To winnow out the wheat from the chaff and to prepare it in an easily digested shape for the tender stomachs of the first and second year students taxes the resources of the most capable teachers.

4. Second year medical students at one institution were assigned required readings that totaled ___ hours per week.Taylor,N Engl J Med 1992
7. Excerpt from: Upon this ageEdna St Vincent Millay 1939 Upon this gifted age, in its dark hour,
Rains from the sky a meteoric shower
Of facts ... they lie unquestioned, uncombined
Wisdom enough to leech us of our ill
Is daily spun, but there exists no loom
To weave it into fabric
8. Critical Thinking
Reasonable reflective thinking focused on what to believe or do
10. Critically Thinking about Your own or Someone Elses Thinking Critical thinking is best understood as the ability of thinkers to take charge of their own thinking. This requires that they develop sound criteria for analyzing and assessing their own thinking and routinely use those criteria and standards to improve its quality.
Elder and Paul, J Dev Educ, 1994
..make sense of our world by carefully examining our thinking, and the thinking of others . . .
Chafee, Thinking Critically, 1988
11. What was the story behind Flight 1549? 22 March 2005 11
12. The Event: We had 208 seconds to plan and problem-solve
The co-pilot and I had to take on different roles than what typically would be done according to protocol. I decided early on that we were best served by me using my greater experience in the [A320] to fly the airplane.
Additionally, I felt like I had a clear view out the left-hand and forward windows of all the important landmarks that I needed to consider. They would be easier for me to see. And ultimately the choice of where we would go and what flight path we would take would be mine.
I also thought that since it had been almost a year since I had been through our annual pilot recurrent training, and Jeff had just completed it he was probably better suited to quickly knowing exactly which checklist would be most appropriate.
16. Intuition in Medicine Aware of knowing something without having to discover or perceive it
Accomplishing the routine
Addressing complex clinical situations that dont have an immediate visible evidence base (NICU sepsis example)
Using advanced pattern recognition skills of Radiologists = Search Superiority

18. Heuristics: Rulesof Thumb Occams Razor : The simplest solution to a clinical problem is most often correct
Availability: You are most likely to use recent clinical experience to guide new experience
Sutton's Law obvious diagnoses more often explain symptoms than non-obvious ones
19.
Didnt know enough about the disease
20. Errors Our propensity for certain types of error is the price we pay for the brains remarkable ability to think and act intuitively. Heuristics play the odds: sometimes, particularly under unusual circumstances, these rules of thumb lead to wrong decisions.
21. Biases Posterior probability -- decision about this patient is unduly influenced by what has gone on before in physicians and or patients past
Suttons slip -- dx possibilities other than the obvious are not given enough consideration
Anchoring -- tendency to lock on to salient features in the initial presentation and failing to adjust
22. Surgical Resident Example: Simulation Setting 50 year old man with multiple trauma (MVC) Level 1
Excellent resident Attendingswantto work with this resident
Patient begins to crash
24. Biases Posterior probability -- decision about this patient is unduly influenced by what has gone on before in physicians and or patients past
Suttons slip -- dx possibilities other than the obvious are not given enough consideration
Anchoring -- tendency to lock on to salient features in the initial presentation and failing to adjust
26. (Part II) Gave him an X-ray slip and told him not to drink until we worked it out
Did not admit to ED
Next day the patient died of an MI en route to the ED
Why didnt the doctor send the patient to the ED?
28. Role of the Teacher/Mentor Help learner gain self-insight (reflective writing tasks)
Focus feedback on thinking (not just behavior)
Explain strategies for learning (how you read the literature)
Model reflection and self-assessment (think out loud)
Serve as a resource (be available)
Use teaching styles and strategies to promote deliberate reflection
29. Deliberate Reflection Systematically think aloud through practice and/or prompting
Account (What did you see?)
Assess (What was good/could be improved?)
Analyze (Look for bias)
Define Alternative(s)
Act (Plan)
Companion to Deliberate Practice (Ericsson, 2007; McGaghie, 2011)

31. Study 1. Self-Generated Reflective Questions (Reading)If students develop and ask themselves questions they learn best
32. Study 2. Pause for Reflection (Lecture)If we talk 6 minutes less students learn more
33. Study 3: Self-explanation. (Computer Learning Modules)Prompting to explain thinking improves critical thinking In a controlled experimental laboratory setting, college students solved problems (similar and structurally different) more effectively and without spending more time using self-explanation prompts.
Authors conclude: This is a particularly important accomplishment in light of the fact that this prompting procedure one that proved to be both effective and efficientis a very simple and easy-to-implement feature for computer-based learning environments.

38. De-Brief Frame Walk me through it -- Tell me what you were thinking and feeling.
What did you see (account)? When did you decide to act order Atropine?
Were you missing something? Are there other explanations for the sudden change in the patients condition?
Resident clearly recognized the patient was crashing but only focused on one vital. Acted before completing the visual/mental checklist.
This is anchoring (name it).
39. De-Brief Frame What would you do differently next time?
What are the alternatives?
40. Simulation Training: Team PerspectiveTrauma Bay: MVA 70 yr old woman with multiple trauma
41. De-Brief Frame Walk me through it -- Tell me what you were thinking and feeling.
How did you view your role and responsibility in relation to the more senior attending?
How did you consider the alternative offered by the attending?
Resident felt anxious and checked her decision-making and clarified her role.
Avoided visceral bias (influence of affective sources of error on decision-making) by reflecting.
42. Summary Critical thinking is reasonable reflective thinking focused on what to believe or do
Metacognition is critically thinking about thinking
Teaching and practicing deliberate reflection improve metacognition
Positive outcomes include greater self-awareness, fewer diagnostic errors, more effective teamwork, greater self-directed learning and improved physician-patient relations
