2.1 Case History

Key Takeaways

  • A complete case history follows a structured sequence—chief complaint, HPI, ROS, PMH/PSH, medications, allergies, family and social history—before any hands-on examination begins.
  • The history of present illness must capture onset, location, quality, severity, timing, aggravating and relieving factors, and associated symptoms to narrow the differential diagnosis.
  • Red-flag answers in the history (fever with spine pain, unexplained weight loss, bowel/bladder dysfunction, progressive neurological deficit) mandate urgent medical referral regardless of musculoskeletal findings.
  • Review of systems screens for comorbid disease that changes examination priorities, contraindications to manipulation, and conditions that mimic mechanical spine pain.
  • Documentation pitfalls—leading questions, incomplete medication lists, and failure to record prior imaging or specialist care—are common NBCE traps that compromise clinical reasoning scores.

2.1 Case History

Clinical Priority: On NBCE Part II and in practice, the case history is not paperwork—it is the first diagnostic test. Roughly 12% of General Diagnosis items assume you can extract clinically decisive information from the patient's story, recognize when the story is incompatible with a benign musculoskeletal problem, and know what additional history closes or opens a dangerous differential.

Opening the Interview

Begin by establishing rapport, confirming identity, and stating your purpose. Use open-ended prompts first: "What brings you in today?" Record the chief complaint (CC) in the patient's own words, briefly. Follow immediately with the history of present illness (HPI), the narrative thread NBCE vignettes almost always test.

A reliable HPI framework is OPQRST (Onset, Provocation/Palliation, Quality, Region/Radiation, Severity, Timing) or OLD CARTS (Onset, Location, Duration, Character, Aggravating/Alleviating factors, Radiation, Timing, Severity). Either works if you are systematic. For spine cases, always ask about mechanism of injury (macrotrauma vs. insidious onset), prior episodes, prior chiropractic or medical care, imaging already performed, and functional limitations (sleep, work, ADLs).

HPI ElementHigh-Yield Clinical QuestionWhy It Matters on Part II
OnsetSudden after lift vs. gradual over weeks?Acute disc herniation vs. degenerative stenosis vs. systemic disease
Location & radiationBand-like chest pain or leg pain below the knee?Visceral or radicular patterns vs. local strain
QualitySharp, tearing, crushing, burning?Aortic pathology, angina, neuropathy red flags
TimingConstant vs. intermittent? Nocturnal?Inflammatory arthritis, tumor, infection
Severity & progressionGetting worse despite rest?Progressive neurologic or systemic disease
Associated symptomsFever, weight loss, GI/GU changes?Infection, malignancy, cauda equina

Review of Systems (ROS)

The ROS is a structured symptom inventory by body system. You do not need every symptom on every patient, but NBCE expects you to know which systems must be screened when the CC involves spine, headache, or chest pain. A pertinent ROS documents positives and relevant negatives; an extended ROS may be required for new patients or complex cases.

For musculoskeletal presentations, always screen at minimum: constitutional (fever, chills, night sweats, weight change), neurologic (weakness, numbness, gait change, bowel/bladder dysfunction), cardiovascular (chest pain, dyspnea, palpitations), GI (abdominal pain, blood in stool), and GU (urinary retention, incontinence, saddle anesthesia companion symptoms). A negative ROS must be documented when it rules out red-flag differentials—"Denies fever, unexplained weight loss, or bowel/bladder changes" is clinically meaningful.

Past, Family, and Social History

Past medical history (PMH) captures chronic illnesses (diabetes, osteoporosis, cancer, cardiovascular disease), hospitalizations, and prior surgeries (PSH)—especially cervical fusion, lumbar laminectomy, or joint replacement, which alter examination and manipulation decisions. Medications must include prescription drugs, OTC analgesics, anticoagulants, corticosteroids, and supplements; anticoagulation and long-term steroid use increase bleeding and infection risk after invasive procedures. Allergies should distinguish true drug allergy (anaphylaxis, rash) from intolerance.

Family history identifies inherited risk: ankylosing spondylitis, rheumatoid arthritis, cardiovascular disease, stroke, diabetes, and malignancy. Social history includes occupation (repetitive loading, vibration), tobacco use, alcohol, recreational drugs, exercise habits, and psychosocial stressors. These factors shape prognosis, compliance, and biopsychosocial differentials tested on Part II.

Red Flags in the History

NBCE frequently pairs a plausible musculoskeletal complaint with a single history detail that should halt routine chiropractic management. Memorize clusters, not isolated buzzwords.

Red-Flag History FindingConsider UrgentlyChiropractic Implication
Fever + spine painEpidural abscess, osteomyelitis, discitisNo manipulation; immediate medical referral
Age >50 + new headache + jaw claudicationGiant cell arteritisSame-day steroid pathway; avoid vigorous cervical treatment
Thunderclap headache (maximal at onset)Subarachnoid hemorrhageEmergency referral
Unexplained weight loss + night painMalignancy, infectionImaging and medical workup first
Bowel/bladder dysfunction + saddle symptomsCauda equina syndromeSurgical emergency
Progressive bilateral leg weaknessCord compressionUrgent MRI; no delay for conservative trial
History of cancer + new focal bone painMetastasisImaging before high-velocity manipulation
Anticoagulation + recent traumaIntracranial or spinal hematomaModified exam; imaging if concern
Chest pain radiating to arm/jaw with exertionAngina/MICardiac evaluation before thoracic manipulation

Connecting History to Differential Diagnosis

Strong candidates articulate how history narrows the differential. Example: insidious unilateral neck pain with morning stiffness improving with activity suggests inflammatory spondyloarthropathy; same-region pain after rear-end collision with delayed onset fits whiplash-associated disorder; sudden worst headache of life does not belong in a cervicogenic headache pathway.

Use clinical reasoning statements NBCE rewards: "The absence of fever and IV drug use makes epidural abscess less likely but does not eliminate it if examination finds fever later—vitals and neuro exam must confirm." Always note what history would change your plan if positive.

Documentation and Exam Pitfalls

Common PitfallConsequenceCorrect Approach
Leading questions ("The pain goes down your leg, right?")False radicular historyAsk open-ended, then clarify
Recording diagnosis before examPremature closureDocument CC and HPI before conclusions
Ignoring prior records/imagingMissed fracture or tumorRequest and review outside studies
Incomplete medication listMiss anticoagulation or immunosuppressionVerify name, dose, frequency
No mechanism of injury in traumaCannot grade stabilityDocument MOI, seatbelt, loss of consciousness
Skipping ROS negativesCannot defend red-flag clearanceDocument pertinent negatives explicitly

Chiropractic-Specific History Pearls

Ask about previous manipulation (response, adverse events), contraindications (rheumatoid atlantoaxial instability, acute fracture, active infection), and patient goals. For headache patients, screen HAART-style triggers: Hypertension history, Age >50 for new headache, Atrial fibrillation or cardiac history, Rapid onset, Trauma. For chest pain, always clarify pleuritic vs. exertional quality before attributing symptoms to thoracic spine dysfunction.

On Part II, case-history items often ask which additional history question is most appropriate next, which finding most increases concern for referral, or which element is missing from a sample note. Read the vignette twice: first for the obvious musculoskeletal story, second for the one sentence that contradicts a benign course. That second read is where General Diagnosis points are won or lost.
