However, most standard methods that seek to adjust for the potential selection bias induced by restricting to individuals with complete data fail to address the heterogeneous structure of EHR. To address this,\u00a0a framework\u00a0was previously proposed that modularizes the data provenance that gives rise to the observed data as a sequence of decisions made by patients, healthcare providers, and the health system. In this work, we formalize analyses with this framework, specifically by proposing a pragmatic, flexible, and scalable framework for estimation and inference that blends inverse probability weighting and multiple imputation. The proposed framework allows better alignment between consideration of missingness assumptions to the complexity of EHR data. In addition to formal theoretical justification and simulation studies, we illustrate the proposed framework with a motivating data application in which EHR data are used to investigate weight loss outcomes following bariatric surgery, and whether differences between two surgery types exhibit effect modification by presence\/absence of chronic kidney disease.<\/jats:p>","DOI":"10.1002\/sim.70151","type":"journal-article","created":{"date-parts":[[2025,7,15]],"date-time":"2025-07-15T10:59:27Z","timestamp":1752577167000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Adjusting for Selection Bias Due to Missing Data in Electronic Health Records\u2010Based Research by Blending Multiple Imputation and Inverse Probability Weighting"],"prefix":"10.1002","volume":"44","author":[{"given":"Tanayott","family":"Thaweethai","sequence":"first","affiliation":[{"name":"Massachusetts General Hospital Biostatistics  Boston Massachusetts USA"},{"name":"Department of Medicine Harvard Medical School  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajarshi","family":"Mukherjee","sequence":"additional","affiliation":[{"name":"Department of Biostatistics Harvard T.
