What Should Be Included in Salient Features of a Clinical Case
Salient features should highlight only the pertinent positive and negative clinical findings that directly relate to the diagnosis, along with key demographic details, presenting complaints, relevant physical examination findings, and critical diagnostic results—essentially the discriminating features that distinguish this case from alternative diagnoses. 1
Core Components to Include
Patient Demographics and Presentation
- De-identified demographic details: age, sex, ethnicity, occupation
- Additional relevant information: BMI, hand dominance (when applicable)
- Mode of presentation: ambulance arrival, emergency room walk-in, or physician referral
- Chief complaint: the patient's main symptoms in their own words 1
Clinical Findings That Matter
- Relevant physical examination findings only—avoid excessive detail that obscures the case
- Pertinent positive findings: abnormalities that support your diagnosis
- Pertinent negative findings: absent findings that help exclude alternative diagnoses 2
Essential Historical Elements
- Past medical and surgical history with outcomes from prior interventions
- Medication history including allergies
- Psychosocial factors: smoking, substance use, living situation (when relevant)
- Family history: particularly genetic information when applicable 1
Diagnostic Information
- Key investigation results: laboratory values, imaging findings, histopathology
- Prognostic characteristics: staging information for tumors or genetic conditions
- Differential diagnoses considered and why they were ruled out 1
Critical Pitfall to Avoid
The most common mistake is including irrelevant material or excessive detail that obscures the essence of the case. 2 Research demonstrates that salient but distracting clinical features can misdirect diagnostic reasoning and cause errors—these should be acknowledged but not overemphasized 3.
Practical Example
For a 35-year-old male post-Fontan procedure presenting with headaches:
Salient Features:
- 35-year-old male with tricuspid atresia, status post-Fontan (total cavopulmonary modification) in childhood
- Presenting complaint: headaches and visual disturbances
- Cardiovascular examination: no acute findings
- Standard coagulation tests: normal
- Thrombodynamics test: severe hypercoagulation with spontaneous clot formation
- Pertinent negative: no clear cardiovascular cause on initial workup 4
This example demonstrates conciseness—it includes only discriminating features that led to the diagnosis of hypercoagulability requiring anticoagulation, while excluding extraneous details about the patient's childhood surgery or unrelated systems.
Key Principle
The discussion of salient features should emphasize how these findings relate to the diagnosis, their significance in distinguishing between alternatives, and their prognostic implications—not simply list every finding documented in the chart 2.
