Could you provide a link to that study? I searched the JAMA website and was unable to find it.

Amazing, that JAMA has had numerous studies and articles examining the number, all much lower than this, and this one is the only one reported.
According to the IOM (again?) the number is currently around 48,000 (down from 90,000 in the '80s), while another study has it much less, around 5000 to 15,000.
Typical of the mainstream media.
