External validation of a predictive model for reintubation after cardiac surgery: A retrospective, observational study.

ABSTRACT:

Study objective

Explore validation of a model to predict patients' risk of failing extubation, to help providers make informed, data-driven decisions regarding the optimal timing of extubation.

Design

We performed temporal, geographic, and domain validations of a model for the risk of reintubation after cardiac surgery by assessing its performance on data sets from three academic medical centers, with temporal validation using data from the institution where the model was developed.

Setting

Three academic medical centers in the United States.

Patients

Adult patients arriving in the cardiac intensive care unit with an endotracheal tube in place after cardiac surgery.

Interventions

Receiver operating characteristic (ROC) curves and concordance statistics w
