How to Present a Case by Organ Systems
When presenting a case systematically by organ systems, organize your presentation using a structured head-to-toe approach that covers constitutional symptoms first, followed by each major organ system in a logical sequence, documenting both positive and pertinent negative findings for each system.
Recommended Systematic Presentation Format
1. Constitutional/General Assessment
Start with overall patient status 1, 2:
- Vital signs: Temperature, blood pressure, heart rate, respiratory rate, weight, height
- General appearance: Body habitus, evidence of distress, wasting, obesity
- Constitutional symptoms: Fever, night sweats, fatigue, weight changes (specify amount and timeframe), malaise
2. Head, Eyes, Ears, Nose, Throat (HEENT)
Document specific findings 1, 2, 3:
- Head: Facial features, dysmorphic characteristics
- Eyes: Vision changes, proptosis, conjunctival findings (erythema, pallor, icterus), lacrimation, periorbital edema, "allergic shiners"
- Ears: Tympanic membrane appearance, hearing changes
- Nose: Nasal patency, septal deviation, turbinate appearance (edema, pallor, erythema), discharge characteristics, polyps
- Throat/Mouth: Oral lesions, ulcers, thrush, gum disease, tonsillar size, tongue abnormalities
3. Neck
- Lymphadenopathy (cervical, supraclavicular)
- Thyroid examination (enlargement, tenderness, nodules)
- Jugular venous distension
4. Cardiovascular System
- Symptoms: Chest pain characteristics, palpitations, orthopnea, paroxysmal nocturnal dyspnea
- Examination: Heart sounds, murmurs, rhythm irregularities, peripheral pulses, edema, signs of heart failure
- Functional status: Exercise tolerance, dyspnea on exertion (specify activity level that triggers symptoms)
5. Respiratory/Pulmonary System
- Symptoms: Dyspnea at rest vs. exertion, cough (productive vs. dry), hemoptysis, wheezing
- Examination: Respiratory rate, breath sounds, rales, wheezing, stridor, chest wall abnormalities
- Functional impact: Ability to perform activities of daily living
6. Gastrointestinal System
- Symptoms: Abdominal pain (location, character), nausea, vomiting, diarrhea, constipation, hematochezia, changes in appetite
- Examination: Abdominal tenderness, distension, hepatomegaly, splenomegaly, masses, bowel sounds
- Nutritional status: Dietary assessment, weight trends
7. Genitourinary/Renal System
- Symptoms: Hematuria, dysuria, flank pain, urinary frequency, incontinence
- Examination: Flank masses, suprapubic tenderness, testicular/scrotal examination when relevant
- Renal function markers: Creatinine, estimated GFR, proteinuria, electrolytes
8. Musculoskeletal System
- Symptoms: Joint pain, bone pain, muscle weakness, limitations in mobility
- Examination: Joint swelling, deformities, range of motion, muscle strength, gait abnormalities
- Functional impact: Ability to perform activities, ambulatory status
9. Neurological System
- Symptoms: Headaches, seizures, weakness, sensory changes, paresthesias, memory problems, concentration difficulties, dizziness
- Examination: Mental status, cranial nerves, motor strength, sensory function, reflexes, coordination, gait
- Cognitive function: Attention, memory, word-finding ability
10. Psychiatric/Mental Health
- Mood changes, depression, anxiety, sleep disturbances
- Changes in libido, concentration, memory
- Screen for depression and domestic violence when appropriate
11. Dermatologic/Integumentary
- Rashes (distribution, character), lesions, nodules, ulcers
- Skin discoloration, purpura, petechiae
- Nail changes, hair changes
12. Endocrine System
2:
- Symptoms of hyperglycemia, thyroid dysfunction, hypogonadism
- Polydipsia, polyuria
- Temperature intolerance
13. Hematologic/Lymphatic
- Lymphadenopathy (generalized vs. localized, size, consistency)
- Easy bruising, bleeding tendencies
- History of anemia or cytopenias
Key Implementation Points
The order matters: This head-to-toe systematic approach ensures completeness and prevents omissions 2, 7. Each system should include both symptoms (patient-reported) and signs (examination findings).
Document pertinent negatives: Explicitly state absence of key symptoms in each system, as this information is diagnostically valuable 5, 2.
Quantify when possible: Use specific measurements, timeframes, and severity descriptors rather than vague terms 4, 5.
Tailor depth to clinical context: While all systems should be addressed, emphasize systems most relevant to the presenting complaint while maintaining systematic completeness 1, 7.
This structured approach, derived from multiple specialty guidelines 1, 4, 5, 2, 7, ensures comprehensive patient assessment and facilitates clear communication among healthcare providers.
