# Medical Diagnosis Skill Use this skill when analyzing clinical cases, evaluating symptoms, or providing diagnostic recommendations. ## When to Use - User presents symptoms, clinical findings, or patient data - Need to develop differential diagnoses - Evaluating diagnostic test results - Providing clinical recommendations - Case-based clinical reasoning ## Diagnostic Process ### 1. Information Gathering - Collect relevant patient history - Identify presenting symptoms and duration - Review available diagnostic findings - Note risk factors and comorbidities ### 2. Clinical Analysis - Identify key clinical findings - Correlate symptoms with possible conditions - Consider anatomical and physiological relationships - Evaluate severity and urgency ### 3. Differential Diagnosis Generate ranked differential diagnoses considering: - **Likelihood**: Based on prevalence and presenting features - **Severity**: Urgent vs. chronic conditions - **Treatability**: Modifiable vs. static conditions - **Classic presentations**: Typical vs. atypical features ### 4. Diagnostic Recommendations Recommend appropriate next steps: - Additional tests or imaging - Specialist consultations - Treatment trials - Monitoring parameters ## Output Structure For each diagnosis, provide: ``` Primary Diagnosis: - Condition: [name] - Confidence: [High/Medium/Low] - Rationale: [key supporting evidence] Differential Diagnoses: 1. [Condition] - likelihood %, supporting findings 2. [Condition] - likelihood %, supporting findings Recommended Next Steps: - [Specific recommendation with rationale] ``` ## Best Practices - Always acknowledge uncertainty explicitly - Cite medical literature when available (PubMed, guidelines) - Flag urgent findings requiring immediate attention - Consider patient-specific factors (age, comorbidities, medications) - Prefer evidence-based recommendations - Include appropriate medical disclaimers ## Red Flags Always highlight: - Signs of sepsis or systemic infection - Cardiac emergencies (ACS, dissection, PE) - Neurological emergencies (stroke, meningitis) - Oncologic emergencies - Metabolic emergencies (DKA, thyroid storm) ## References - UpToDate (when available) - PubMed clinical guidelines - ACC/AHA, ESC cardiovascular guidelines - WHO diagnostic criteria
