Patient Portals Show Data Points, Not Patient Stories: One Clinician's Case for Change-Over-Time Views

PA-C Lisa Zahakos argues that current patient portals present health data as isolated snapshots rather than as a coherent longitudinal narrative, making it difficult for patients to understand how their health is actually changing over time. Her piece calls for health records to surface trends, context, and meaningful change rather than just the most recent measurement.

Why it matters

The argument Zahakos is making is not new, but it keeps getting made because the problem keeps not getting solved. Portals surface results. They do not surface meaning. A cholesterol value from last Tuesday sits next to a discharge summary from 2009 with no thread connecting them, no sense of direction, no clinical story. For a patient trying to understand whether they are getting better or worse, that is close to useless.

The fix sounds straightforward: show what changed, show the trend, show the context. But the reason this has not happened at scale is not purely a design failure. It is a data quality and documentation problem. Trends are only interpretable when the underlying data is consistently structured, coded, and contextually annotated. Many EHRs are not there yet. That does not make Zahakos wrong. It means that anyone serious about building this kind of longitudinal view needs to work on the data layer just as hard as the display layer.

What to watch

Whether EHR vendors respond to this framing with genuine longitudinal design changes or simply repackage existing trend graphs as a new feature.
