When the chart doesn't follow the patient.

Around late October, the traffic heading south on Interstate 75 starts to change. Michigan plates. Ontario plates. Anyone who works in a Florida clinic knows exactly what that means: the snowbirds are coming back.

Take one of them. Carol, 74, retired teacher. She is a composite, but if you practice in Fort Myers you have met her a hundred times. Summers outside Grand Rapids, winters on the Gulf coast. A cardiologist in Michigan, a primary care doctor in Florida, and both of them good at their jobs.

In November, the cardiologist adjusts her blood thinner. In January, Carol walks into her Florida clinic for refills, and the chart on the screen still shows the old dose. Nothing in it mentions November at all.

Nobody made a mistake. Her two health systems simply do not share a chart. Her record splits at the state line, and each half grows on its own.

Most people assume this got fixed years ago. The government's own numbers say otherwise. The federal office that tracks health information technology reported that as of 2023, 43 percent of American hospitals routinely do all four things that make a record actually move: send it, receive it, find it, and pull it into their own system. That figure was 28 percent in 2018, so it is genuinely improving. It is also still not half.

And “moved” is a low bar. Ask any clinician what shows up when an outside record does arrive. Faxes. Portal printouts. A 90 page PDF where the one medication change that matters is sitting on page 61. The doctor seeing Carol has a visit booked for fifteen minutes and that stack to dig through, assuming it came at all.

The cost of working from half a picture is not abstract. Researchers at Johns Hopkins estimated in BMJ Quality & Safety that diagnostic error kills or permanently disables around 795,000 Americans every year. An incomplete record does not cause every one of those. But of all the reasons a diagnosis goes wrong, not knowing what the last doctor knew is among the most fixable.

Two decades of federal standards work did accomplish something real. The pipes exist now, and they mostly carry water. That deserves more credit than it gets. What never got built is the layer that reads what comes through, reconciles it, and hands the clinician the three things worth knowing before Carol sits down.

That missing layer is why we started Valinor. I'll write more about what we're building in the coming weeks. For now, hold on to Carol. Everything a doctor needs to know about her exists, written down, somewhere. It has just never been in the same room at the same time.
