Diane Meier, MD, Director of the Center to Advance Palliative Care, et al., wrote in a 2003 article, "A National Survey of Physician-Assisted Suicide and Euthanasia in the United States," that appeared in The New England Journal of Medicine:
“Eleven percent of the physicians [1,902 total] said that under current legal constraints, there were circumstances in which they would be willing to hasten a patient’s death by prescribing medication, and 7 percent said that they would provide a lethal injection… Since entering practice, 18.3 percent of the physicians…reported having received a request from a patient for assistance with suicide and 11.1 percent…had received a request for a lethal injection. Sixteen percent of the physicians receiving such requests…or 3.3 percent of the entire sample, reported that they had written at least one prescription to be used to hasten death, and 4.7 percent…said that they had administered at least one lethal injection.”
