"Hypnosis is now available to patients at some of the most respected medical institutions in the country"

An article in the New York Times talks about hospitals now starting to act on data from years of studies on using hypnosis to help make medical treatment faster, easier, less traumatic and less expensive. Quoting the article:
A study by radiologists at Harvard Medical School, published in 2000, found that patients who received hypnosis during surgery required less medication, had fewer complications and shorter procedures than patients who did not have hypnosis. In a follow-up study in 2002, the radiologists concluded that if every patient undergoing catheterization were to receive hypnosis, the cost savings would amount to $338 per patient.

And:
...hypnosis is now available to patients at some of the most respected medical institutions in the country, including Stanford Hospital, the Cleveland Clinic, Mount Sinai Medical Center and Beth Israel Medical Center in New York.

While the effects are impressive, they are hardly widely known yet.
“My neurosurgeon was stunned at how little medication I required before and after surgery, and how quickly I bounced back,” she [the patient, Ms. Ritchie] said.
