D/D Drill 5: Thought Process Tracing
🧠 Mission 5: Thought Process Tracing
── Let's put the flow of thought itself into words
🩺 Background of this mission
Within the D/D Drill mode, this "Mission 5" holds a somewhat unique position. Through a "play-by-play commentary" that reads and interprets a patient's condition and progress, we will consciously trace the
thought process itself of "how I thought about it."
Here, the AI partner "Kuroda" will present how it "thinks out loud" regarding a case.
It is an experience like peering directly into the mind of a veteran doctor. I will show you an actual example in the second half.
🎯 Mission Structure
It unfolds in the following flow:
Case presentation (practical emergency case)
Your mission
- List differential diagnoses
- Consider initial response
- Instruct Kuroda to "speak" if necessaryKuroda's play-by-play
- Introduction, development, judgment, action, documentation—verbalizing the "why?" for each
🧪 What this mission trains
Focus points for differential diagnosis
Assigning meaning to vitals and physical findings
Prioritizing initial response decisions
Ability to convey thoughts to others (conference skills)
🧭 Target user profile
Junior residents who feel challenged in organizing their thoughts
Medical students who want to polish their "way of generating" differentials
Senior residents who want to acquire the habit of verbalizing presentations
People on night shift who don't feel like studying seriously but feel guilty about being too lazy (me)
🧠 Mission 5: Tracing Thought Circuits
How do you put actual thinking into words? Kuroda will appear as an example of this.
Come on, let's think about it together.
🚨 Case Presentation:
A 70-year-old male. Found collapsed at home by family and transported by ambulance.
Consciousness level: JCS 200 (opens eyes to pain, but poor response)
Blood pressure: 82/50 mmHg
Pulse: 112 bpm, irregular
Pupils: No asymmetry
Findings: Paralysis in the right upper and lower limbs
No head trauma, no obvious fever or nuchal rigidity
🎯 Your Mission:
Differential diagnoses to consider (especially life-threatening ones)
Tests and procedures to perform in initial management
You can also hear Kuroda's play-by-play by typing "tell me" if needed
💬 When you say "tell me"—
🧠 Kuroda's Thought Circuit Play-by-Play:
The structure of "70-year-old male," "sudden disturbance of consciousness," and "right-sided paralysis" catches my eye.
I immediately assume a cerebrovascular accident (CVA), specifically a massive infarction or hemorrhage in the left cerebral hemisphere.
A JCS 200 consciousness level means "opens eyes to pain but poor response." Since there is right-sided paralysis, the lesion is in the left hemisphere.
Normal pupils, no head trauma → low probability of brain herniation or traumatic hemorrhage.
Looking at the vitals: BP 82/50, pulse 112 and irregular.
This "irregularity" is the key.Cerebral embolism associated with atrial fibrillationis what I suspect most strongly.
🔎 Differential diagnoses to establish at this point:
【Lethal diseases to check first】
Brainstem hemorrhage (however, hemiplegia + normal pupils → probability is somewhat low)
Extensive cerebral infarction (especially cardioembolic)
Cerebral venous sinus thrombosis (rare, but not zero)
【Things to consider with priority】
Cardioembolic stroke due to Af
Hypertensive intracerebral hemorrhage (subcortical, etc.)
【Others to keep in mind】
Hypoglycemia or metabolic consciousness disorder (cannot explain paralysis)
Infectious diseases such as meningitis (findings are scarce at this moment)
🧪 Tests to perform and initial actions:
Head CT (differentiation between hemorrhage vs. infarction)
ECG (confirmation of arrhythmia, presence of Af)
Blood glucose, electrolytes, lactate (metabolic exclusion)
ABG (hypoxia, pH abnormality)
Oxygen administration, fluid replacement, and consider vasopressors if necessary
📜 If you are to record it, summarize it like this:
“70-year-old male, transported with sudden consciousness disorder and right hemiplegia. Vital signs are low and arrhythmia is present. Cardioembolic stroke associated with Af is most suspected. CT and ECG are scheduled to be performed immediately.”
🧭 What's next?
You can stop here, or continue to tackle other cases.
If you try 'thinking out loud' yourself, you will surely gain new perspectives.
🗂 Mission 5──The goal is to "verbalize the thinking process itself."
This is the first step toward strengthening your own clinical reasoning.
