Name of the Procedure:

CHA2DS2-VASc Risk Score Documentation (G9931)

Summary

The CHA2DS2-VASc risk score assessment is a routine calculation used to evaluate the risk of stroke in patients with atrial fibrillation (AF). The score ranges from 0 to 9, with higher scores indicating a greater risk of stroke. A CHA2DS2-VASc score of 0 or 1 signifies a low risk of stroke, often guiding decisions around anticoagulation therapy.

Purpose

The CHA2DS2-VASc score helps determine a patient's risk of stroke and informs the need for anticoagulation to prevent stroke in those with AF. A score of 0 or 1 typically suggests that anticoagulation may not be necessary, thus reducing unnecessary medication and its associated risks.

Indications

• Patients diagnosed with atrial fibrillation (AF)
• Patients needing risk stratification for stroke
• Consideration for anticoagulant treatment initiation or continuation

Preparation

• No specific pre-procedure instructions required.
• Ensure recent medical history, especially regarding previous stroke, heart failure, hypertension, diabetes, and vascular diseases.
• Review patient’s age and sex, as both are components of the scoring system.

Procedure Description

1. Medical History Review: Collect relevant clinical data concerning the patient's age, sex, history of congestive heart failure, hypertension, stroke or transient ischemic attack (TIA), vascular disease, and diabetes.
2. Score Calculation:
   • Congestive heart failure/LV dysfunction: 1 point
   • Hypertension: 1 point
   • Age ≥ 75 years: 2 points
   • Diabetes Mellitus: 1 point
   • Stroke/TIA/thromboembolism: 2 points
   • Vascular disease (PAD, MI, aortic plaque): 1 point
   • Age 65-74 years: 1 point
   • Sex category (female): 1 point
3. Interpretation: Sum the points to determine the risk score.
4. Documentation: Record the risk score and discuss the findings with the patient.

Duration

Approximately 10-15 minutes.

Setting

Can be performed in various clinical settings, including primary care offices, cardiology clinics, and outpatient clinics.

Personnel

Typically conducted by a healthcare provider such as a primary care physician, cardiologist, physician assistant, or nurse practitioner.

Risks and Complications

• No physical risks or complications as it is a non-invasive assessment.
• Potential for misinterpretation if not all patient history data is accurate.

Benefits

• Guides clinical decision-making regarding anticoagulation therapy.
• Prevents unnecessary use of anticoagulation in low-risk patients.
• Minimizes stroke risk through appropriate treatment.

Recovery

No recovery is necessary as it is a non-invasive risk assessment procedure.

Alternatives

• Other stroke risk calculators or models (e.g., HAS-BLED for bleeding risk).
• Regular medical consultations to periodically assess AF management and stroke risk.

Patient Experience

• Non-invasive and straightforward with no discomfort involved.
• Results discussed immediately with actionable clinical advice provided based on the score.

Pain management and comfort measures are not relevant due to the non-invasive nature of the procedure.
