Created by Veterans for Veterans

A health record that spans years, not portals.

A longitudinal record organizes health events over time so a Veteran can follow the sequence of diagnoses, treatment, tests, medications, symptoms, and trends across different systems.

What makes a record longitudinal

A document archive stores files. A longitudinal record also organizes events by time and preserves relationships among them. It can show what happened before and after a diagnosis, how a medication changed, whether results moved over time, and which facility supplied each piece of information.

Why this matters for Veterans

Veterans may receive care during service, through multiple VA facilities, from community-care providers, and from civilian physicians over decades. Portals and institutions change, but the need to understand the complete history remains. A Veteran-controlled record is designed to follow the person rather than a single provider.

Important qualities of a trustworthy timeline

  • Source traceability: every important item remains tied to its facility, document, and date.
  • Uncertainty: incomplete and conflicting information remains visible.
  • Context: laboratory values and diagnoses are not separated from the encounter that produced them.
  • Continuity: earlier history can be compared with recent care.
  • Veteran control: the Veteran determines what information is added and what is shared.

From a timeline to useful questions

Once information is organized, a Veteran can ask more focused questions: When did this condition first appear in the available record? What changed after treatment? Which outside records are still missing? What should I ask at my next appointment?

Organization is not clinical interpretation

Patterns in a record may be useful for discussion, but they are not automatically diagnoses or proof of causation. Qualified healthcare professionals remain responsible for medical interpretation and decisions.

Keep the source. See the sequence.

PBRx.Vet is being designed to turn disconnected records into a durable, searchable health history.
