Diabetes can steal your vision. Slowly, painlessly, and, here’s the tragedy, preventably. A photo of the back of your eye catches it years before you notice anything wrong. The cameras exist. The people trained to read the photos exist. And still, people go blind.
Why? Because the photo never gets taken.
Follow the chain. You’re at your primary-care doctor for diabetes. Someone needs to remember you need an eye photo, find time in a chaotic day, take the photo, send it somewhere, get it read, get the result back, tell you the result, and book the follow-up if something’s wrong. That’s seven handoffs. Every handoff leaks patients. By the end, a fraction of the people who needed screening got it.
Notice what the bottleneck isn’t. It isn’t the camera, that problem was solved years ago. It isn’t the reading, trained eyes and good software both exist. The bottleneck is the boring stuff: who does what, when, and who checks that it happened.
I keep running into this pattern. Most of healthcare’s unsolved problems aren’t medicine problems. They’re logistics problems wearing a medicine costume. We keep inventing better cameras while patients fall through the gaps between the camera and the follow-up.
The next breakthrough in preventive care won’t be a better algorithm. It’ll be someone who makes the seven handoffs happen without heroics, every patient, every Tuesday, no exceptions.
