Study: Depression and assisted suicide in Oregon.

By Alex Schadenberg
Executive Director - Euthanasia Prevention Coalition

People in Washington State need to be aware that if the assisted suicide initiative is passed, people who experience depression will not be protected by "Oregon Style" assisted suicide guidelines.

A recently published study by Ganzini et al found that 15 of 58 (26%) of people who requested assisted suicide in Oregon were experiencing depressive disorders. Even though many of those people were incompetent or unable to "freely choose" assisted suicide, they were given a prescription for lethal drugs and died by assisted suicide.

The study by Linda Ganzini, Elizabeth R. Goy, and Steven K Dobscha - BMJ2008;337;a1682 states in its conclusion:

Our study suggests that most patients who request aid in dying do not have a depressive disorder. However, the current practice of the Death with Dignity Act in Oregon may not adequately protect all mentally ill patients, and increased vigilance and systematic examination for depression among patients who may access legalised aid in dying are needed. Tools for screening for depression such as those used in our study are easy to administer and may help to determine which patients need further evaluation by a mental health professional. Further study is needed to determine the effect of treatment of depression on the choice to hasten death.
Ganzini et al, studied 58 patients in Oregon who requested assisted suicide. Most of these people were dying of cancer or ALS - Lou Gehrig's disease.

Ganzini et al specifically studied patients who had requested assisted suicide:

our surveyed participants had taken active steps to pursue a physician's aid in dying in one of the few jurisdictions where it is legal - all either explicitly requested aid in dying from a physician or contacted Compassion and Choices for information on the Oregon Death with Dignity Act. Before death, almost half had obtained a prescription for a lethal drug under the law.
Of the 58 people who participated in the study, 26% (15) were independently diagnosed with depression. The study stated:
Among patients who requested a physician's aid in dying, one in four had clinical depression. However, more than three quarters of people who actually received prescription for lethal drugs did not have a depressive disorder. Our findings also indicate that the current practice of legalised aid in dying may allow some potentially ineligible patients to receive a prescription for a lethal drug; two of those who ultimately died by lethal ingestion had depression at the time that they received a prescription for a lethal drug and died by ingestion the drug. A third patient was depressed at the time that she requested a physician's aid in dying and probably received her prescription; she was successfully treated for her depression before she died by lethal ingestion.
Further to the concern in Oregon that people with depressive disorders are dying by assisted suicide Ganzini et al acknowledge that:
In a study of 321 psychiatrists in Oregon only 6% were very confident that in a single evaluation they could adequately determine whether a psychiatric disorder was impairing the judgement of a patient requesting assisted suicide. In a study of 290 US forensic psychiatrists, 58% indicated that the presence of major depressive disorder should result in an automatic finding of incompetence for the purpose of obtaining assisted suicide.
Proponents of assisted suicide will say that since their are safeguards in Oregon that mandate that someone who has a depressive disorder or mental illness must receive a psychiatric or psychological assessment before receiving a prescription for a lethal drug, that these few cases simply represent an oversight by the physician.

The reality is that of the 49 cases of assisted suicide in Oregon, last year, not one of the people who died by assisted suicide were referred for a psychiatric or psychological assessment.

Ganzini supports assisted suicide and is researching the implications of the assisted suicide law.

This study proves that safeguards in Oregon are either ignored or ineffective.

The Euthanasia Prevention Coalition recognizes that assisted suicide threatens the lives of people at the most vulnerable time of their life.
