Score of Gomes et al for Predicting Carbapenem-Resistant Gram-Negative Bacteremia in a Hospitalized Patient

Description

Gomes et al reported a score for identifying a patient at high-risk for carbapenem-resistant Gram-negative bacteremia. This can help to identify a patient who requires careful selection of antibiotics. The authors are from multiple institutions in Brazil.

Parameters:

(1) previous infection (unclear if any infection or due to a Gram-negative bacteria)

(2) mechanical ventilation

(3) use of carbapenem

(4) length of hospital stay prior to episode of sepsis, in days

Parameter	Finding	Points
previous infection	no	0
	yes	1
mechanical ventilation	no	0
	yes	1
use of carbapenem	no	0
	yes	1
length of hospital stay	< 19 days	0
	>= 19 days	1

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 4

• A score <= 1 "excludes" (it would be better to say low risk for) carbapenem-resistant Gram-negative sepsis.

• A score >= 3 was used to identify high risk for carbapenem-resistant Gram-negative sepsis.

Performance:

• The area under the ROC curve is 0.80.
