"I've been very obsessive about writing science fiction for far too many years. Anyone with an ounce of sense would have given up years ago."
- Charles Stross

The term autodoc is probably most associated with Ringworld, which won both the Hugo and the Nebula awards for best novel for Niven.

But they got him into the autodoc anyway. It was a puppeteer-shaped coffin, form-fitted to Nessus himself, and bulky Puppeteer surgeons and mechanics must have intended that it should handle any conceivable circumstance. But had they thought of decapitation?

They had. There were two heads in there, and two more with necks attached, and enough organs and body parts to make several complete puppeteers. Grown from Nessus himself, probably; the faces on the heads looked familiar.

Here's how Niven uses it in The Warriors (1966):

"Nowadays surgery was normally done by autodocs..."

For awhile, Jim Davis was very busy. Everyone, including himself, had a throbbing blinding headache. To each patient, Dr. Davis handed a tiny pink pill from the dispenser slot of the huge autodoc which covered the back wall of the infirmary...

The autodoc also appears in Madness Has Its Place, a 1990 story by Niven. This intriguing story explores the uses of different personalities in society. Are there occasions when you need people who are, well, unbalanced and not very social? Can an automated medical device provide what is needed to keep you balanced - and then unbalance you if needed?

"Something is happening in Aristarchus, something that requires a medic."

"Run it in an autodoc. Ten personality choices. The chemical differences aren't big, but...infantry, which means killing on foot..."

For the most part, expert systems running on computers may make use of data from EEG or other monitors to provide a better visualization of the data for medical staff (see Penn Researchers Develop Smart Intensive Care Unit System Using Advanced Computer Intelligence. Only a few systems actually allow the hardware itself to make an intervention in the patient's care; for example, if a patient's vital signs merit it, additional drugs may be injected intravenously.
