Learning about learning health systems: Strengthening theory through continuous evaluation and improvement

This article contributes to the field by offering a practical methodology for bridging the gap between LHS theory and practice. By promoting ongoing theorizing and evaluation, our framework aims to both enhance the effectiveness and adaptability of LHSs, as well as inform theory development. Challenges remain, including resource intensity for data infrastructure and potential limitations in data quality or accessibility, which must be addressed to realize the full potential of LHSs as adaptive, theory-driven systems.
