Score of Gannon et al for a Patient with Interstitial Lung Disease (ILD) and Acute Respiratory Failure

Description

Gannon et al developed a simple score for evaluating a patient with interstitial lung disease and acute respiratory failure. This can help to identify a patient who may benefit from more aggressive management. The authors are from Columbia University in New York City.

Patient selection: acute respiratory failure in setting of interstitial lung disease

Outcome: in-hospital mortality and cumulative 1-year mortality

Parameters:

(1) sex

(2) diagnosis of idiopathic pulmonary fibrosis

(3) body mass index (BMI), in kg per square meter

(4) mechanical ventilation or extracorporeal life support

(5) able to ambulate

(6) SAPS II score

Parameter	Finding	Points
sex	female	0
	male	2
diagnosis of idiopathic pulmonary fibrosis	no	0
	yes	1
BMI	<= 25	0
	26 to 30	1
	31 to 35	2
	> 35	3
mechanical ventilation or extracorporeal life support	no	0
	yes	2
ambulation	yes	0
	no	1
SAPS II	<= 20	0
	21 to 30	3
	> 30	4

total score =

= SUM(points for all 6 parameters)

Interpretation:

• minimum score: 0

• maximum score: 13

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

Score	Risk for Mortality	In-Hospital Mortality	Cumulative 1-Year Mortality
0 to 4	low	33%	57%
5 to 8	moderate	65%	81%
9 to 13	high	96%	96%

Performance:

• The area under the ROC curve was 0.73 (optimism corrected).
