Burch-Wartofsky Score (Thyroid Storm)

Quantifies likelihood of thyroid storm (thyrotoxic crisis). Score >= 45 = thyroid storm; 25-44 = impending storm.

Used in: Thyroid Disorders

Score interpretation

Thyroid storm unlikely (< 25)

→ Not thyroid storm; investigate other causes of tachycardia/fever; optimise thyroid function

Impending thyroid storm (25-44)

→ High suspicion; treat as thyroid storm: propylthiouracil (PTU), iodine (1 hour after PTU), beta-blocker, hydrocortisone; ICU monitoring

Thyroid storm likely (>= 45)

→ Thyroid storm: ICU; PTU 200-400mg TID (or carbimazole); saturated potassium iodide (SSKI) after PTU; propranolol; IV hydrocortisone 300mg then 100mg TID; cooling; treat precipitant
