Depiction of current EHRs in a LHS. Although current EHRs provide longitudinal patient data storage, they typically visualize only snapshots of the state of individual patients. In addition, they provide little support for research uses of the data or stakeholder decision making to improve care quality at lower cost. This figure depicts a snapshot view of four patients' medical records, accessed by their providers (red arrows), with no patient population view. EHR, electronic health record; LHS, learning health system.
