I now have comprehensive material to compose a complete, well-structured answer. Let me compile everything.
History Taking (OLDCAARTS) and Complete Physical Examination
Part 1 — The Complete Medical History
A complete history-and-physical (H&P) follows a standardized format. The sections below are drawn from Neuroanatomy through Clinical Cases (3rd ed.), Goldman-Cecil Medicine, and Kaplan & Sadock's Synopsis of Psychiatry.
1. Chief Complaint (CC)
A succinct, 1–2 sentence statement — ideally in the patient's own words — that captures:
- Patient's age and sex
- Primary presenting problem
- Relevant brief context
Example: "A 53-year-old man with known hypertension presenting with crushing substernal chest pain of 1 hour's duration."
2. History of Present Illness (HPI) — Use OLDCAARTS
The HPI is the chronological, detailed narrative of the current problem. Use the OLDCAARTS mnemonic to ensure nothing is missed:
| Letter | Element | Key Questions |
|---|
| O | Onset | When did it start? Was it sudden or gradual? What were you doing when it began? |
| L | Location | Where exactly is the symptom? Can you point to it? Does it radiate or spread? |
| D | Duration | How long does it last? Is it constant or intermittent? |
| C | Character | What does it feel like? (sharp, dull, burning, throbbing, pressure-like, cramping) |
| A | Aggravating factors | What makes it worse? (movement, eating, exertion, position, stress) |
| A | Alleviating/Relieving factors | What makes it better? (rest, medications, heat/cold, eating) |
| R | Radiation | Does the symptom travel anywhere? (e.g., arm, jaw, back, groin) |
| T | Timing | When does it occur? Any pattern? (morning, postprandial, nocturnal, with exertion) |
| S | Severity | On a scale of 0–10, how bad is it? How does it affect daily activities? |
Important: Always include pertinent negatives — symptoms that are absent are as diagnostically valuable as those present. Prior episodes, prior treatment, and the effect on function should also be documented.
3. Past Medical History (PMH)
- Prior medical illnesses (chronic conditions: DM, HTN, asthma, CAD, CKD, etc.)
- Prior surgical and procedural history (with dates)
- Prior hospitalizations
- Childhood illnesses
- Obstetric/gynecologic history (in women): gravida, para, last menstrual period
4. Medications and Allergies
- All current medications: prescription, over-the-counter, vitamins, herbal supplements — include dose, route, and frequency
- Allergies: document the specific reaction (e.g., hives, anaphylaxis, rash), distinguish true allergies from intolerances (e.g., GI upset from NSAIDs)
- Document NKDA (no known drug allergies) if applicable
5. Family History (FHx)
- Health status and cause of death of first-degree relatives (parents, siblings, children)
- Familial diseases relevant to the HPI: premature cardiovascular disease, DM, cancer, genetic disorders, psychiatric illness, autoimmune conditions
- A family tree (genogram) format is concise and clear
Example: "Mother died at 64 of MI, had HTN. Father had MI at 52 and DM, died at 73 of stroke. One sibling, healthy."
6. Social and Environmental History (SocHx)
- Occupation and occupational exposures
- Living situation: who lives with the patient, housing conditions
- Marital/relationship status, dependents
- Travel history (domestic and international)
- Sexual history: orientation, partners, contraception, STI risk
- Habits:
- Tobacco: type, pack-years, current/former/never
- Alcohol: type, quantity, CAGE/AUDIT screen
- Illicit drugs or substance use
- Physical activity and diet
- Military service history (screen for PTSD if applicable)
- Educational background and health literacy
7. Review of Systems (ROS)
A systematic, head-to-toe inquiry to identify problems not covered in the HPI. If something relevant surfaces, move it to the HPI. Key systems to cover:
| System | Symptoms to Screen |

| GU | Dysuria, frequency, hematuria, urgency, incontinence; for men: erectile dysfunction |
| OB/GYN | LMP, menstrual irregularity, vaginal discharge, menopausal symptoms |
| Musculoskeletal | Joint pain/swelling, stiffness, back pain, muscle weakness |
| Neurological | Headache, dizziness, seizures, weakness, numbness/tingling, memory changes |
| Psychiatric | Depression, anxiety, sleep disturbance, suicidal ideation |
| Dermatologic | Rashes, lesions, pruritis, hair/nail changes |
