This past Friday Dr. Ruggiero, Assistant Professor in the Division of Pulmonary and Critical Care at UT Southwestern, gave grand rounds and talked about chronic critical illness. She referred to the “ProVent” score which is a prognostic model for 1-year mortality in patients ventilated for 21 days or more. This was a prospective cohort study and identified 4 independent predictors of 1-year mortality with 1 point assigned to each variable:
1. Vasopressor requirement
3. Age greater than or equal to 50 years
4. Platelets < 150,000
A score of 0 is associated with 15% mortality compared to a score of 3 and 97% mortality. Click on the link below to review this 2008 study!
