# Quo Vadis CASUS? From predicting to impacting outcomes in cardiac surgery

Published:January 13, 2022
Prognosis models in the intensive care unit (ICU) such as the Cardiac Surgery Risk Score (CASUS) are expected to facilitate risk-adjustment of outcome data, objective communication of a patient's condition, and provide guidance regarding clinical decision-making and resource allocation (Hekmat et al. 2005). We welcome the contributions made by Sudarsanan et al., in their recent publication, assessing the external validity of CASUS in a relatively understudied population (Sudarsanan et al. 2021).
