It starts where you do: with a patient presenting a symptom. From there, it guides systematic evaluation using the same structured input every time-OPPQRRST (Onset, Provocation, Position, Quality, Radiation, Relief, Severity, Time)-to extract patterns that matter.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eEvery symptom chapter follows the same risk-stratified structure: \u003c\/p\u003e\u003cp\u003e- IMMEDIATE RISK - life-threatening conditions requiring immediate action\u003c\/p\u003e\u003cp\u003e- TIME-SENSITIVE - conditions where delay worsens outcomes\u003c\/p\u003e\u003cp\u003e- HIGH-YIELD - commonly missed or high-impact presentations \u003c\/p\u003e\u003cp\u003e- QUICK WINS - reversible or benign causes often overlooked\u003c\/p\u003e\u003cp\u003e- TRAPS - cognitive errors and diagnostic pitfalls to avoid\u003c\/p\u003e\u003cp\u003e- PATTERN COMPRESSIONS - rapid-fire associations for memory consolidation\u003c\/p\u003e\u003cp\u003e- CORE RULE - the single most important principle for that symptom\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThis is not reading material.
