Dr William Toffler (left) acknowledges no slippery slope cause-and-effect evidence, with Drs Bentz and Stevens
A new scholarly journal focused on end-of-life ethics, decision-making and practice has just been launched: the Journal of Assisted Dying. In the first article, claims by Oregon lobby group Physicians for Compassionate Care (PCC), including Doctors Bill (William) Toffler and Ken Stevens (and others) are assessed against empirical evidence and found to be completely wrong, or highly misleading as a result of selective use of data.
The new scholarly journal, the Journal of Assisted Dying, is dedicated to careful and holistic analysis of evidence in regard to the various forms of assisted dying that are lawful in a number of jurisdictions around the world... and to practices in jurisdictions where assisted dying remains illegal.
In the first article of a series on Oregon, I examine claims and speculations made by various doctors (and others who quote them), that Oregon has the second-highest suicide rate in the USA (or is always in the top 10), that Oregon's Death With Dignity Act has resulted a massive increase in the state's general suicide rate, and other astonishing statements.
Of course, the empirical evidence from the Oregon Health Authority and from the USA Centers for Disease Control and Prevention does not support these statements and interpretations, and I analyse and critique the evidence.
Some of the claims are just plain factually and hugely wrong. Others are the result of failing to read their sources more carefully, misunderstanding what the data actually represents. Still further claims are made on the basis of selectively-chosen statements from government reports, while omitting statements that are contrary to, or provide alternative and well-researched explanations for Oregon's recently rising general suicide rate.
Drs Toffler and Stevens have even published some of their claims and speculations in the British Medical Journal.1 It goes to show that even good journals sometimes publish bunkum: their article was a letter to the editor rather than peer-reviewed research. Great care is required to sort real evidence from hype and opinion.
Ultimately, Dr Bill Toffler of PCC has acknowledged on video that there is no cause-and-effect evidence between Oregon's Death With Dignity Act and Oregon's suicide rate, an acknowledgement that went unchallenged by his two PCC colleagues present at the time, Dr Ken Stevens and Dr Chuck (Charles) Bentz. You can see Dr Toffler's statement here (at 10'50").
The Journal of Assisted Dying is an open-access journal, and you can read the full article here.

Abstract
Background: Several physicians have speculated that Oregon’s general suicide rate is evidence of suicide contagion as a result of Oregon’s Death With Dignity Act (‘the Act’). Methods: Search and analysis of physician and related online sources of Oregon suicide contagion speculation; retrieval and analysis of cited Centers for Disease Control and Prevention (CDC) and other publications relied upon; analysis of authoritative, public Government mortality data for Oregon and other USA states. Results: Several physicians have speculated about Oregon suicide statistics in a manner that is not supported by the cited publications, or by public CDC mortality database data. The claims variously (a) misrepresent key data in the publications, (b) omit information in the publications that is at variance with suicide contagion speculation, and (c) overlook other significant information at variance with speculation. The physicians have previously acknowledged inability to prove perceived “slippery slope” effects of the Act. Other opponents of the Act have republished the physicians’ erroneous information. Conclusions: Evidence advanced by several physicians to speculate that Oregon’s Death With Dignity Act causes suicide contagion in Oregon is variously false, misleading or highly selective—omitting key facts—and has arisen even though the physicians acknowledge they have no proof of ‘slippery slope’ effects.
