Medical Assistance in Dying for Mental Illness as a Sole Underlying Medical Condition and Its Relationship to Suicide: A Qualitative Lived Experience-Engaged Study: Aide Médicale à Mourir Pour Maladie Mentale Comme Seule Condition Médicale Sous-Jacente et Son Lien Avec le Suicide: Une Etude Qualitative Engagée Dans l'Expérience Vécue.

Objective: This lived experience-engaged study aims to understand patient and family perspectives on the relationship between suicidality and medical assistance in dying when the sole underlying medical condition is mental illness (MAiD MI-SUMC).

Method: Thirty individuals with mental illness (age M = 41.8 years, SD = 14.2) and 25 family members (age M = 47.5 years, SD = 16.0) participated in qualitative interviews examining perspectives on MAiD MI-SUMC and its relationship with suicide. Audio recordings were transcribed and analysed using reflexive thematic analysis. People with lived experience were engaged in the research process as team members.

Results: Four main themes were developed, which were consistent across individuals with mental illness and family members: (a) deciding to die is an individual choice to end the ongoing intolerable suffering of people with mental illness; (b) MAiD MI-SUMC is the same as suicide because the end result is death, although suicide can be more impulsive; (c) MAiD MI-SUMC is a humane, dignified, safe, nonstigmatized alternative to suicide; and (4) suicidality should be considered when MAiD MI-SUMC is requested, but suicidality's role is multifaceted given its diverse manifestations.

Conclusion: For patient-oriented mental health policy and treatment, it is critical that the voices of people with lived experience be heard on the issue of MAiD MI-SUMC. Given the important intersections between MAiD MI-SUMC and suicidality and the context of suicide prevention, the role that suicidality should play in MAiD MI-SUMC is multifaceted. Future research and policy development are required to ensure that patient and family perspectives guide the development and implementation of MAiD MI-SUMC policy and practice.
