BACES Score of Kim et al for Predicting Mortality in a Nontuberculous Mycobacterial Pulmonary Infection

Description

Kim et al reported the BACES score to predict mortality for a patient with a lung infection caused by a nontuberculous mycobacterium. The authors are from Armed Forces Capital Hospital, Seoul National University, and Sungkyunkwan University in Seoul.

BACES is an acronym based on the first letter of the 5 parameters.

Patient selection: nontuberculous mycobacterial lung infection

Parameters:

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

(2) age in year

(3) lung cavity on chest imaging

(4) elevated ESR

(5) sex

Parameter	Finding	Points
body mass index	< 18.5 kg per sq m	1
	>= 18.5 kg per sq m	0
age in years	< 65 years	0
	>= 65 years	1
lung cavity	no	0
	yes	1
elevated ESR	no	0
	yes	1
sex	female	0
	male	1

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 5

Total Score	Risk Category
0 or 1	low
2 or 3	intermediate
4 or 5	high

Total Score	5-Year Mortality
0	1.2%
1	3%
2	8%
3	21%
4	48%
5	83%

Performance:

• The c-index was 0.81 in the derivation and 0.85 in the validation cohorts.
