Fairness for Whom? Learning Health Systems' Approach to Equity in Healthcare.

Many healthcare systems use "equity" as a catch-all term to underscore their commitment to delivering care matching users' needs. Despite its ubiquity, it is often haphazardly used and applied to care and improvement efforts. As the learning health systems (LHSs) approach gains prominence, LHS researchers have sought to embed equity into their work while navigating systems with differing views of equity. We examine several components of equity, its definitions within LHSs and knowledge from LHSs' equity approach that could be implemented across systems. We conclude by suggesting various ways in which readers can embed equity into their respective LHSs.
