Longitudinal data abstraction on Patient 1's medical record (gold arrows) and interpretation of Patient 1's data to form information, the second level in the DIKW pyramid (Fig 2). Current EHRs typically display only snapshot views (thin gray arrows, Fig 1). With the ability to interpret longitudinal data, future EHRs could visualize a patient's cancer journey and provide basic support for correlating clinical features with genetic testing over time.
