Hospital Mortality Score of Roch et al for a Patient with Acute Respiratory Distress Syndrome (ARDS) Treated with Extracorporeal Membrane Oxygenation (ECMO)

Description

Roch et al developed a score for predicting hospital mortality for a patient with the acute respiratory distress syndrome (ARDS) requiring therapy with extracorporeal membrane oxygenation (ECMO). This can help to identify a patient who may benefit from more aggressive management. The authors are from Aix Marseille Universite in France.


 

Patient selection: ARDS started on ECMO at an outside hospital and transferred to a referral hospital. Most used veno-venous circuits.

 

Parameters:

(1) age in years

(2) influenza pneumonia

(3) SOFA score

= SUM(points for all 3 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 4

• The higher the score the greater the in-hospital mortality.

Performance:

• The area under the ROC curve for the study was 0.80.

• Klinzing et al found that the score did not predict survival in their study population.
