In 2016, medical assistance in dying (MAiD) was decriminalized in Canada with the passage of Bill C-14. Under Bill C-14, competent adults (aged ≥ 18 yr) with a serious and incurable condition in an advanced state of irreversible decline who were experiencing intolerable physical or psychological suffering and whose death was reasonably foreseeable could be eligible for MAiD. 1 After its passage, legal challenges were brought before the Superior Court of Quebec, who ruled that the original legislation was too restrictive and in violation of the Canadian Charter of Rights and Freedoms. 2 This led to the passage of Bill C-7 in March 2021, which amended Canada's criminal code to remove "reasonably foreseeable death" as an eligibility criterion, thus creating 2 distinct pathways for MAiD, where death either is or is not reasonably forseeable. 3 One patient population likely to be affected by these changes is older adults considered to be frail. Clinicians should consider whether factors contributing to frailty are reversible when considering requests for MAiD.MAiD for those in whom death is not reasonably forseeable is subject to additional safeguards including a minimum 90-day period for assessing eligibility and mandatory assessment by a clinician with expertise in the patient's condition. 3 Bill C-7 also permits MAiD through an advanced directive if eligibility was determined when the patient was capable, which is relevant for patients with dementia or those at high risk of developing delirium (both of which often co-exist with frailty).Frailty is a syndrome characterized by reduced physiologic reserve that renders an individual more susceptible to adverse outcomes in response to stressors. 4 Frailty is an underrecognized clinical entity that is distinct from normal aging. In frailty, an accelerated decline results from an accumulation of health deficits, leading to dysregulation of multiple systems over time. Many interrelated biological (e.g., genetics), clinical (e.g., under lying comorbidities) and socioeconomic (e.g., social isolation) factors contribute to this accelerated decline, with frailty being a final common pathway. 4 A recent qualitative study from the Netherlands reported that, among 53 patients who underwent MAiD for "multiple geriatric syndromes," a combination of medical, social and existential issues was often associated with unbearable suffering leading to the MAiD request in the absence of a life-threatening condition. 5 When considering MAiD for frail individuals, it is essential that clinicians address this complex constellation of contributing factors, some of which may be modifiable. For example, frailty related to social isolation, depression and food insecurity may need to be addressed differently than frailty from poorly controlled diabetes, congestive heart failure and recurrent falls.Assessments for frail individuals who request MAiD are challenging given ambiguities in the interpretation of whether frailty is irreversible and incurable, and whether it causes intolerable suffering.
