    Description

    The performance of multiple imputation (MI) models may be enhanced using auxiliary covariates (AC). Data-adaptive approaches to identify ACs for MI models are not well understood.

    This presentation develops and compares high-dimensional MI (HDMI) approaches that leverage structured and natural language processing-derived ACs. It investigates whether HDMI can increase efficiency and decrease bias in real-world evidence studies with partially observed confounders. It was presented at the 2024 ISPE Annual Meeting.
