Quick Summary
Isolated lab reports and scans miss slow trends and repeated signals. Longitudinal records provide continuity that improves clinical decisions.
The limits of snapshots
A single test result rarely explains what is happening. Patterns emerge only when history is visible.
Why continuity matters
Longitudinal records reveal progression, recovery, and response to treatment. They reduce guesswork.
The patient burden today
Patients carry their own continuity across hospitals, doctors, and cities. Technology should carry that burden instead.
This is also why patient understanding lags behind AI outputs. See the patient understanding gap.
The new expectation
Over time, longitudinal records will become a baseline requirement for care.
As standards and interoperability mature, continuity becomes easier to deliver. See the quiet shift in interoperability.
