BAS2IC Score of Kaeuffer et al for Predicting Rapid Progression of COVID-19

Description

Kaeuffer et al reported the BAS2IC score for evaluating a patient with COVID-19. This can help to identify a patient who is at increased ris. The authors are from multiple institutions in France.

Patient selection: COVID-19

Parameters:

(1) body mass index (B) in kg per square meter

(2) age (A) in years

(3) sex (S)

(4) shortness of breath (S) on admission (dyspnea)

(5) inflammatory (I) markers on admission (absolute neutrophil count, absolute lymphocyte count)

(6) serum CRP (C) in mg/L

Parameter	Finding	Points
body mass index	>= 30 kg per sq m	3
	25 to 29.99	2
	< 25 kg per sq m	0
age	<= 65 years	0
	> 65 years	1.5
sex	male	3
	female	0
shortness of breath	no	0
	yes	3.5
absolute neutrophil count	< 8,000 per µL	0
	>= 8,000 per µL	3
absolute lymphocyte count	< 1,000 per µL	1.5
	>= 1,000 per µL	0
serum CRP	< 100 mg/L	0
	100 to 199 mg/L	2
	>= 200 mg/L	5.5

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 21

• The higher the score the greater the risk for the patient.

Score	Risk
<= 6	low
6.5 to 14	intermediate
> 14	high risk

Performance:

• The area under the ROC curve is 0.76.
