[The modified Brussels scale as a predictor of mortality in the Intensive Care Unit].
OBJECTIVE
To compare discrimination and calibration of the modified Brussels score with the Simplified Acute Physiology Score version 3 (SAPS-3) in predicting mortality.


METHODS
A prospective cohort study was carried out.


METHODS
The Respiratory Intensive Care Unit (RICU) of Mexico General Hospital.


METHODS
A total of 251 patients out of 285 admissions to the RICU in 2012 were included. The mean age was 48.4±17.1 years, and 132 of the patients were men (52.8%).


METHODS
None.


METHODS
Demographic data, SAPS-3 score upon admission and the modified Brussels score on the day 1 of stay in the RICU.


RESULTS
On day 1, the modified Brussels and SAPS-3 scores were 4.7 ± 3.8 and 54.7 ± 17.8, respectively. Areas under the ROC curve for the modified Brussels score on day 1 and the SAPS-3 were 0.837 ± 0.025 (95% CI 0.787-0.887) and 0.813 ± 0.027 (95% CI 0.761-0.865), respectively. Hosmer-Lemeshow goodness-of-fit values were 5,885 (P=.660) and 4,026 (P=.855), respectively.


CONCLUSIONS
The modified Brussels score on day 1 offers excellent discrimination and calibration in predicting mortality in the RICU, comparable to that of the SAPS-3.
