Comprehensive H&P Documentation for Neuropathy
A thorough H&P for neuropathy should include specific assessments of small and large fiber function, with particular attention to sensory, motor, and autonomic symptoms in a systematic pattern to identify the type, distribution, and potential causes of neuropathy. 1
History Components
Symptom Assessment
- Sensory symptoms:
- Pain characteristics (burning, shooting, electric-like, stabbing)
- Paresthesias (tingling, pins and needles sensation)
- Dysesthesias (unpleasant abnormal sensations)
- Numbness and distribution pattern (stocking-glove distribution vs. other patterns)
- Timing of symptoms (continuous vs. intermittent)
- Allodynia (pain from non-painful stimuli)
Functional Impact
- Effect on daily activities
- Presence of foot ulcers or injuries
- Falls or balance issues
- Sleep disturbances related to neuropathic symptoms
Risk Factors and Associated Conditions
- Diabetes history:
- Duration of diabetes
- Glycemic control (recent A1C values)
- Other diabetic complications (retinopathy, nephropathy)
- Other potential causes:
- Alcohol consumption
- Medication history (chemotherapy, antibiotics)
- Toxic exposures
- Family history of neuropathy
- Nutritional deficiencies
- Autoimmune disorders
Autonomic Symptoms
- Orthostatic dizziness or syncope
- Gastrointestinal symptoms (early satiety, nausea, constipation)
- Genitourinary symptoms (erectile dysfunction, urinary incontinence)
- Abnormal sweating patterns
- Cardiac symptoms (resting tachycardia)
Physical Examination
Sensory Examination
Small-fiber function assessment: 1
- Pinprick sensation
- Temperature sensation
- Pain perception
Large-fiber function assessment: 1
- Vibration sensation using 128-Hz tuning fork
- Proprioception
- Lower extremity reflexes (ankle, knee)
Protective sensation: 1
- 10-g monofilament testing (critical for identifying risk of foot ulceration)
Motor Examination
- Muscle strength assessment (distal > proximal)
- Muscle bulk/atrophy evaluation
- Assessment for fasciculations
Autonomic Assessment
- Orthostatic blood pressure measurements
- Heart rate variability
- Skin assessment (dry, cracked skin, especially in extremities)
Foot Examination (Critical for Diabetic Neuropathy)
Comprehensive foot inspection: 1
- Skin integrity
- Callus formation
- Ulcerations
- Deformities (hammer toes, Charcot foot)
- Nail abnormalities
Vascular assessment: 1
- Pedal pulses
- Capillary refill
- Skin temperature
- Signs of arterial insufficiency
Documentation of Findings
Pattern Recognition
- Distribution pattern (length-dependent, multifocal, asymmetric)
- Predominant fiber type involved (sensory, motor, autonomic, mixed)
- Temporal progression (acute, subacute, chronic)
Severity Assessment
- Use standardized scales when appropriate
- Document functional limitations
- Note risk classification for complications (especially for diabetic neuropathy)
Differential Diagnosis
- Document consideration of non-diabetic causes of neuropathy 1
- Note findings that suggest alternative diagnoses
Laboratory and Diagnostic Testing
Initial Testing
- Document pertinent laboratory results:
- Blood glucose/A1C
- Complete blood count
- Comprehensive metabolic panel
- Vitamin B12 levels
- Thyroid function tests
Advanced Testing (if performed)
- Electrophysiological studies
- Autonomic function tests
- Skin or nerve biopsy results
Treatment Plan Documentation
Glycemic Control (for Diabetic Neuropathy)
- Target A1C goals
- Medication adjustments
Pain Management
- First-line agents (gabapentin, pregabalin, duloxetine) 2
- Topical treatments
- Non-pharmacologic approaches
Preventive Care
- Foot care instructions
- Follow-up schedule based on risk classification 1
- Referrals to specialists as needed
Common Pitfalls to Avoid
Incomplete sensory testing: Always assess both small and large fiber function using multiple modalities (not just monofilament testing alone).
Missing non-diabetic causes: Remember that diabetic neuropathy is a diagnosis of exclusion; document consideration of other etiologies.
Overlooking autonomic symptoms: Specifically ask about and document orthostatic symptoms, gastrointestinal issues, and genitourinary problems.
Inadequate foot examination: For diabetic patients, a thorough foot exam is essential at every visit if neuropathy is present.
Failure to classify severity: Document risk classification to guide follow-up frequency and preventive measures.
