Newest firstBackgroundQuantitative bias analyses often rely on unrealistic assumptions and do not fully reflect the complexities of healthcare data. MethodsWe describe a plasmode simulation-based bias analysis for residual confounding from unmeasured variables by leveraging granular information from a subset of cohort members. We generated 500 simulated cohorts based on individual-level claims and linked electronic health rec…
Open article record in new tab ↗IntroductionHealth information exchanges (HIEs) provide the capability to electronically move health care information among different health care information systems and store these data for downstream use cases. However, use of data from HIEs for postmarketing surveillance of medical products is not previously explored. ObjectivesTo conduct a pilot descriptive study characterizing data from MyHealth Access Networ…
Open article record in new tab ↗BackgroundTo improve confounding control in healthcare database studies, data-driven algorithms may empirically identify and adjust for large numbers of pre-exposure variables that indirectly capture information on unmeasured confounding factors ( proxy confounders). Current approaches for high-dimensional proxy adjustment do not leverage free-text notes from EHRs. Unsupervised natural language processing (NLP) te…
