The Burch–Wartofsky Point Scale (BWPS) is the sum of points from each domain, using the single highest applicable category per domain.

Domain	Category	Criteria	Points
Thermoregulatory dysfunction (temperature)	None	<37.2 °C (<99.0 °F)	0
	Mild	37.2–37.7 °C (99.0–99.9 °F)	5
		37.8–38.3 °C (100.0–100.9 °F)	10
		38.4–38.8 °C (101.0–101.9 °F)	15
		38.9–39.4 °C (102.0–102.9 °F)	20
		39.5–39.9 °C (103.0–103.9 °F)	25
	Severe	≥40.0 °C (≥104.0 °F)	30
Central nervous system effects	Absent	No agitation, delirium, psychosis, extreme lethargy, seizure or coma	0
	Mild	Agitation	10
	Moderate	Delirium, psychosis or extreme lethargy	20
	Severe	Seizure or coma	30
Gastrointestinal–hepatic dysfunction	Absent	No GI or hepatic features attributable to thyrotoxicosis	0
	Moderate	Diarrhoea, nausea/vomiting or abdominal pain	10
	Severe	Unexplained jaundice	20
Cardiovascular tachycardia	None	<90 beats/min	0
	Mild	90–109 beats/min	5
		110–119 beats/min	10
		120–129 beats/min	15
		130–139 beats/min	20
	Severe	≥140 beats/min	25
Congestive heart failure	Absent	No clinical heart failure	0
	Mild	Pedal oedema	5
	Moderate	Bibasilar rales	10
	Severe	Pulmonary oedema	15
Atrial fibrillation	Present	Documented atrial fibrillation	10
	Absent	No atrial fibrillation	0
Precipitating event	Present	Recent trigger such as infection, surgery, trauma, radioiodine, parturition or drug reaction	10
	Absent	No clear precipitating event	0

BWPS score bands: <25 storm unlikely. 25–44 impending storm. ≥45 highly suggestive of thyroid storm.
