The aim of this study was to determine an appropriate risk model to identify patients at high risk of prolonged ICU stay and to aid patient consent prior to cardiac surgery.
Data were prospectively collected on 5,440 consecutive cardiac surgery cases between April 2009 and March 2012. The primary outcome measure was the combined outcome of prolonged ICU stay (length of stay greater than 20 days) and/or in-hospital mortality. Logistic regression was performed to assess the predictability of logistic EuroSCORE against the primary outcome. Low-risk, medium- risk and high-risk groups were identified and subsequent risk of 1-year mortality assessed. Survival status was determined at 1 year.
Using an existing risk prediction model, a patient's risk of prolonged ICU stay can be calculated using contemporaneous data. This information could be relevant for aiding in providing informed consent for cardiac surgery patients.
