A new paper introduces "alert-list concordance" to evaluate imputation strategies in ICU sepsis prediction, focusing on whether different pipelines identify the same high-risk patients. The study found that while many imputation methods showed similar aggregate discrimination (AUROC), their patient selections varied significantly, with Jaccard similarities ranging from 0.518 to 0.750. Notably, ForwardFill performed as an outlier, exhibiting higher discrimination but the lowest alert list overlap. The research also indicated that deep imputation methods did not outperform mean imputation on discrimination and were significantly slower. AI
