Machine learning models show a pooled area under the receiver operating characteristic curve of 0.83, indicating strong predictive ability for ICU mortality.
The pooled sensitivity and specificity for predicting mortality in ICU patients were found to be 0.72 and 0.81, respectively.
This systematic review and meta-analysis synthesized data from 40 studies with 317028 patients to assess machine learning model performance.
While showing potential, many studies had limitations due to lack of external validation, calling for multicenter prospective studies.
