Market-level prescription and sales data can tell you what is happening; share shifts, volume inflections, and the impact of events like launches or access changes. But it often can’t tell you why it’s happening, who is driving it, or what friction is preventing demand from converting into durable utilization. The missing layer is the patient.

Patient-level insight is only as strong as the integrity of the patient identifier. If patient IDs are inaccurately assigned, longitudinal analytics degrade quickly: persistence rates distort, switching behavior misreads, and the “patient story” fractures.

“Patient truth” is becoming the investing edge. In categories where access is dynamic, affordability is a gating factor, and persistence is fragile, the patient journey is the market. Longitudinal claims data doesn’t just refine forecasts; it changes what you choose to forecast including conversion rates, friction points, and the real drivers of durable utilization.
