Why do two names exist?

Because precision and comprehension pull in different directions. Clinical vocabulary must distinguish conditions unambiguously for records and billing; patient-facing vocabulary must be understood. Health record systems increasingly carry both.

Is this a diagnostic tool?

No. It is a terminology reference showing how conditions are named. It contains no clinical guidance and should not be used to interpret symptoms.

Yes. It comes from The National Library of Medicine's Clinical Table Search Service, key-free. Nothing is invented or simulated, and if the source cannot be reached the saver reports that instead of drawing something plausible.

Does it cost anything or need an account?

No. Every screensaver here is free, runs in the browser and needs no sign-up. This one uses a public API that requires no key.

What They Call It Screensaver

The What They Call It screensaver pairs the clinical name of a condition with the consumer name for the same thing — the vocabulary clinicians pick from in electronic health records, alongside the words patients actually use. It runs in the browser with nothing to install; press ESC to exit.

How the What They Call It screensaver works

The saver reads The National Library of Medicine's Clinical Table Search Service, key-free.

No account and no key: the request goes straight from your browser, or from this site's own refreshed copy of the feed where the source does not permit browser access.

Values are drawn on a canvas that resizes with the window, so it works on a laptop or a wall display.

If the source is unreachable the saver says so on screen rather than showing stale numbers as though they were current.

A worked example

Two columns: the clinical term on the left, the consumer term on the right where one differs. “Myocardial infarction” and “heart attack” are the same row. Where the two are identical the right column says so. The search rotates through the alphabet so the list keeps moving rather than sitting on one letter.
