ProVent 14 Score for prolonged mechanical ventilation

Determine risk of 1-year mortality after prolonged mechanical ventilation


Prolonged mechanical ventilation (PMV) patients have survived the immediate phase of critical illness but often have poor long-term survival. The Provent 14 score was developed to predict 1-year mortality in patients requiring PMV.

Using 5 simple clinical variables measured on day 14 of mechanical ventilation, the Provent 14 score can accurately predict the 1-year mortality for this population. These data may help inform discussions with the patient or their surrogates about the patient’s values and preferences for care.
