Quick reference

Patient History and Interviewing

  • Record the chief complaint in the patient's own words, including onset, duration, frequency, intensity, location, radiation, and aggravating or relieving factors.

  • Use OPQRST for pain: Onset, Provocation/Palliation, Quality, Region/Radiation, Severity, and Timing.

  • Screen for red flags: bowel or bladder dysfunction, saddle anesthesia, unexplained weight loss, fever, night pain, cancer history, trauma, and progressive neurologic deficit.

  • Past medical history includes chronic illnesses, prior surgeries, hospitalizations, injuries, allergies, immunizations, medications, family history, and social history.

  • Review of systems surveys constitutional, cardiovascular, respiratory, gastrointestinal, genitourinary, musculoskeletal, neurologic, endocrine, skin, and psychiatric symptoms.

  • Medication review should identify anticoagulants, corticosteroids, opioids, antihypertensives, glucose-lowering agents, and documented adverse reactions.

  • Social and occupational history includes job demands, repetitive loads, ergonomics, smoking, alcohol use, exercise, and home responsibilities.

  • For pediatric, geriatric, pregnant, or cognitively impaired patients, obtain collateral history and screen for abuse or neglect when indicated.

Quick reference

Physical Examination Procedures

  • Vital signs include blood pressure, heart rate, respiratory rate, temperature, height, weight, and BMI; orthostatic hypotension is a systolic drop of at least 20 mm Hg or diastolic drop of at least 10 mm Hg.

  • Examination sequence commonly proceeds with inspection, palpation, percussion, and auscultation, followed by region-specific orthopedic and neurologic testing.

  • Range of motion is assessed actively and passively, noting restriction, pain provocation, crepitus, and end-feel.

  • Neurologic screening includes dermatomal sensation, myotomal strength, deep tendon reflexes, proprioception, and pathologic reflexes such as Babinski.

  • Deep tendon reflexes are graded 0 absent, 1+ diminished, 2+ normal, 3+ exaggerated, and 4+ with clonus.

  • Manual muscle testing is graded 0 to 5: 0 no contraction, 1 trace, 2 movement without gravity, 3 against gravity, 4 against some resistance, and 5 normal.

  • Orthopedic tests include straight leg raise, Spurling, Kemp, Gaenslen, Patrick/FABER, Phalen, and Tinel, each interpreted with corresponding history and neurologic findings.

  • Vascular assessment includes pulses, capillary refill, edema, skin color and temperature, and comparison of bilateral extremities.

Quick reference

Diagnostic Imaging and Laboratory/Diagnostic Studies

  • Plain radiography is indicated for trauma, suspected fracture or dislocation, deformity, red flags, and failure to improve after conservative care.

  • MRI is preferred for suspected disc herniation with radiculopathy, spinal cord compression, infection, tumor, cauda equina syndrome, and unexplained neurologic deficit.

  • CT provides detailed bony anatomy and is useful for complex fractures or when MRI is contraindicated.

  • Ultrasound evaluates soft-tissue structures, gallbladder disease, vascular flow, and obstetric conditions without ionizing radiation.

  • Common laboratory studies include CBC, comprehensive metabolic panel, ESR, CRP, HbA1c, lipid panel, TSH, and urinalysis, selected according to the differential diagnosis.

  • Gadolinium contrast is avoided in severe renal impairment, especially eGFR below 30 mL/min/1.73 m², and requires caution in pregnancy or prior contrast reaction.

  • Radiation safety follows ALARA: As Low As Reasonably Achievable, with shielding, limited fields, and avoidance of unnecessary studies.

  • Bone scan can detect occult fracture, metastasis, or infection; EMG/NCS evaluates peripheral nerve and radicular dysfunction.

Quick reference

Diagnosis and Clinical Impression

  • Rule out serious pathology first: fracture, infection, tumor, cauda equina syndrome, spinal cord compression, vascular emergency, and progressive neurologic deficit.

  • Radiculopathy is supported by dermatomal sensory change, myotomal weakness, diminished reflex, and positive tension signs in a corresponding nerve root distribution.

  • Cauda equina syndrome is suggested by saddle anesthesia, bowel or bladder dysfunction, bilateral leg weakness, and abrupt onset; it requires urgent MRI and referral.

  • A differential diagnosis is generated, prioritized, and revised as history, examination, imaging, and laboratory data accumulate.

  • The clinical impression synthesizes the chief complaint, history, examination, and test results into a working diagnosis that guides care.

  • ICD-10 coding should be as specific as the documented diagnosis allows and must be supported by the record.

  • Comorbidities and psychosocial factors can alter prognosis and treatment response and should be included in diagnostic reasoning.

  • Distinguish a working diagnosis from a definitive diagnosis and document the basis for each diagnostic conclusion.

Quick reference

Chiropractic Adjustive Technique and Therapeutic Management

  • High-velocity, low-amplitude manipulation applies a rapid thrust to a specific joint; mobilization uses slower, graded movement.

  • Screen for contraindications including fracture, dislocation, unstable ligamentous injury, severe osteoporosis, spinal infection, tumor, bleeding disorder, and anticoagulation.

  • Obtain and document informed consent before manipulation, including expected benefits, material risks, alternatives, and the right to refuse.

  • Flexion-distraction uses table-assisted flexion and traction and is often selected for discogenic pain or radiculopathy when thrust manipulation is not tolerated.

  • Therapeutic modalities include cryotherapy, heat, electrical stimulation, ultrasound, traction, and soft-tissue techniques, selected by condition and stage of healing.

  • Exercise prescription specifies frequency, intensity, duration, and progression, with reassessment of tolerance and functional response.

  • Document the technique, region treated, patient response, and any adverse reaction after each treatment.

  • Reassess after a defined trial of care and modify or discontinue treatment if functional improvement is not occurring.

Quick reference

Case Management, Referral, and Co-management

  • Urgent referral is indicated for suspected fracture, infection, tumor, cauda equina syndrome, progressive neurologic deficit, vascular emergency, or unexplained systemic symptoms.

  • Consider referral or advanced imaging when a patient fails to improve after an appropriate trial of care, typically four to six weeks.

  • Co-management requires sharing examination findings, diagnosis, and treatment plans with another clinician while clarifying each provider's responsibilities.

  • Referral letters should state the reason for referral, relevant history, objective findings, working diagnosis, treatments provided, and requested consultation.

  • Case management includes informed consent, patient education, goal setting, outcome measurement, and coordination of ancillary services.

  • Discharge is appropriate when goals are met, symptoms are stable, the patient can self-manage, or maximal benefit has been reached.

  • Document referrals, communications, authorizations, and patient responses to maintain continuity and defensibility.

  • Insurance and payer requirements may include preauthorization, medical necessity documentation, and periodic treatment plan review.

Quick reference

Ethics, Jurisprudence, and Risk Management

  • Practice within the state-defined scope of chiropractic care and maintain active licensure and required continuing education.

  • Informed consent requires disclosure of diagnosis, proposed treatment, expected benefits, material risks, alternatives, and the right to refuse.

  • HIPAA protects individually identifiable health information by limiting use and disclosure and requiring appropriate safeguards.

  • Malpractice requires proof of duty, breach of the standard of care, causation, and damages.

  • Mandatory reporting may include suspected child or elder abuse, certain communicable diseases, and impaired colleagues as defined by state law.

  • Maintain professional boundaries, avoid dual relationships, and refrain from misrepresentation of credentials or treatment outcomes.

  • Fraud and abuse include billing for services not rendered, upcoding, and improper inducements; documentation must support every claim.

  • Risk reduction includes timely records, clear consent, appropriate referral, and avoidance of treatment beyond competence or scope.

Quick reference

Documentation and Record Keeping

  • Use the SOAP format: Subjective, Objective, Assessment, and Plan, to organize each encounter and support clinical reasoning.

  • Record the chief complaint, history, examination findings, diagnosis, treatment provided, patient response, and follow-up plan for every visit.

  • Objective documentation includes vital signs, range of motion, neurologic tests, orthopedic tests, and validated outcome scores.

  • Document informed consent, risks and benefits discussed, alternatives offered, and the patient's decision.

  • Late entries must be dated, timed, identified as late, signed, and must not alter the original record.

  • Amendments should preserve the original entry and include the date, time, and identity of the person making the change.

  • Maintain confidentiality and secure records in compliance with HIPAA and state privacy laws.

  • Follow state and payer record-retention requirements and document referrals, communications, and release authorizations.
