Comprehensive History and Physical Examination for Sickle Cell Disease Patients
When taking a history from a patient with sickle cell disease, you must systematically assess their baseline disease status, current complications, medication adherence, and psychosocial factors—all of which directly impact morbidity and mortality.
Essential Historical Components
Disease-Specific History
Genotype and Baseline Values
- Document the specific SCD genotype (HbSS, HbSC, HbS/β-thalassemia) 1, 2
- Obtain baseline hemoglobin, reticulocyte count, and white blood cell count 1
- Review hemoglobinopathy testing results with the patient 1
Pain History
- Characterize typical pain patterns: location, frequency, triggers, and duration 1, 3
- Document what analgesic regimen works for the patient specifically 3
- Ask about pain triggers including dehydration, temperature extremes, physical exertion, stress, and infections 1
- Determine if current pain is typical or atypical for the patient 3
Acute Complications History
- Fever: Any temperature ≥38.5°C requires urgent evaluation 1
- Acute chest syndrome: Previous episodes, symptoms of chest pain, shortness of breath, fever 1, 4
- Stroke/TIA: Any focal neurologic symptoms, history of abnormal transcranial Doppler 1, 5
- Priapism: Episodes, duration, home management attempts, need for urgent intervention 1, 6
- Splenic sequestration: Particularly in young children, history of acute anemia with splenomegaly 1
Chronic Complications Assessment
Organ System Review
- Eyes: Visual changes suggesting proliferative retinopathy 1
- Hepatobiliary: Right upper quadrant pain, jaundice (cholelithiasis) 1
- Musculoskeletal: Hip or shoulder pain (avascular necrosis) 1
- Skin: Leg ulcers, particularly around ankles 1
- Genitourinary: Enuresis (common due to hyposthenuria), hematuria 1
- Cardiovascular: Exercise intolerance, dyspnea (pulmonary hypertension) 5
- Neurologic: Cognitive changes, school performance issues 2
Medication and Treatment History
Current Medications
- Disease-modifying therapy (hydroxyurea, voxelotor, crizanlizumab) and adherence 1, 2
- Penicillin prophylaxis status (if age-appropriate) 1
- Chronic opioid therapy details 2
- Folic acid supplementation 1
Transfusion History
- Dates and indications for previous transfusions 1
- History of transfusion reactions, particularly delayed hemolytic transfusion reactions 4
- Iron overload status if chronically transfused 1
Preventive Care Status
Immunizations
Screening Tests
- Transcranial Doppler results (children) 5, 2
- Recent echocardiogram if pulmonary hypertension suspected 5
- Retinal examination status 1
Physical Examination Priorities
Vital Signs and General Assessment
- Oxygen saturation: Baseline SpO2 should be documented; <94% warrants investigation for pulmonary hypertension 5
- Temperature: Fever is an emergency requiring immediate evaluation 1
- Growth parameters: Plot height, weight; delayed growth and puberty are common 1
Focused Physical Findings
Cardiopulmonary
- Auscultate for murmurs suggesting pulmonary hypertension or valvular disease 5
- Assess work of breathing, signs of acute chest syndrome 4
Abdominal
- Palpate for splenomegaly (splenic sequestration in children, functional asplenia in adults) 1
- Hepatomegaly (chronic hemolysis, iron overload) 1
- Right upper quadrant tenderness (cholelithiasis) 1
Musculoskeletal
- Assess joints, particularly hips and shoulders for limited range of motion (avascular necrosis) 1
- Examine lower extremities for leg ulcers 1
Neurologic
- Critical: Perform focal neurologic examination annually in adults and whenever symptoms suggest stroke 2
- Assess for signs of stroke or TIA: facial droop, weakness, speech changes 1
Skin
Psychosocial Assessment
Mental Health Screening
- Mandatory annual screening using validated tools (PHQ-A, GAD-7, SCARED) 2
- Assess for depression, anxiety, and quality of life 2
- Screen for substance use (alcohol, tobacco, illicit drugs) that may precipitate crises 1
Social Determinants
- Insurance status and access to care 1, 2
- Transportation barriers 1
- School or work accommodations 1
- Support systems and family dynamics 1
Age-Specific Considerations
Infants (0-1 year)
- Confirm diagnosis with hemoglobinopathy testing 2
- Teach parents to palpate spleen for sequestration 1
- Establish baseline laboratory values 2
Children (1-12 years)
- Developmental screening if delays suspected 2
- School performance tracking 2
- Penicillin prophylaxis adherence 1
Adolescents and Adults (12+ years)
- Genetic counseling: Partner testing, contraception options, pregnancy planning 1
- Transition planning to adult care 1
- Vocational and educational goals 1
- Sexual health and contraception (prefer progestin-only methods due to thrombosis risk) 1
Critical Red Flags Requiring Immediate Action
- Fever ≥38.5°C 1
- Chest pain with dyspnea (acute chest syndrome or acute coronary syndrome) 7, 4
- Focal neurologic deficits (stroke) 1
- Priapism >4 hours 6
- Acute severe anemia with splenomegaly (sequestration) 1
- Severe abdominal pain (consider multiple etiologies including vaso-occlusive crisis, cholecystitis) 1
Documentation Essentials
Every encounter should document:
- Current genotype and baseline laboratory values 1, 2
- Medication list with adherence assessment 1
- Pain management plan that works for this specific patient 3
- Medical home and specialist contacts 1
- Individualized care plan for acute complications 1
Common pitfall: Assuming all SCD patients present similarly. HbSS patients typically have more severe acute events, while HbSC and HbS/β-thalassemia patients may present with more chronic complications 8. Tailor your assessment to the specific genotype and individual disease trajectory 9.
