The Canadian province of Quebec has recently legalized medical aid in dying (MAID) for competent patients who satisfy strictly defined criteria. The province is considering extending the practice to incompetent patients. We compared the attitudes of four groups of stakeholders toward extending MAID to incompetent patients with dementia.
We conducted a province-wide postal survey in random samples of older adults, informal caregivers of persons with dementia, nurses, and physicians caring for patients with dementia. Clinical vignettes featuring a patient with Alzheimer's disease were used to measure the acceptability of extending MAID to incompetent patients with dementia. Vignettes varied according to the stage of the disease (advanced or terminal) and type of request (written or oral only). We used the generalized estimating equation (GEE) approach to compare attitudes across groups and vignettes.
Response rates ranged from 25% for physicians to 69% for informal caregivers. In all four groups, the proportion of respondents who felt it was acceptable to extend MAID to an incompetent patient with dementia was highest when the patient was at the terminal stage, showed signs of distress, and had written a MAID request prior to losing capacity. In those circumstances, this proportion ranged from 71% among physicians to 91% among informal caregivers.
We found high support in Quebec for extending the current MAID legislation to incompetent patients with dementia who have reached the terminal stage, appear to be suffering, and had requested MAID in writing while still competent.
加拿大魁北克省最近将医疗辅助自杀(MAID)合法化,适用于满足严格定义标准的有能力的患者。该省正在考虑将该做法扩展至无行为能力的患者。我们比较了四组利益相关者对将 MAID 扩展至患有痴呆症的无行为能力患者的态度。
我们在随机抽取的老年人、痴呆症患者的非正式护理者、护士和照顾痴呆症患者的医生中进行了全省范围的邮寄调查。使用阿尔茨海默病患者的临床案例来衡量将 MAID 扩展至患有痴呆症的无行为能力患者的可接受性。案例根据疾病阶段(晚期或终末期)和请求类型(仅书面或口头)而有所不同。我们使用广义估计方程(GEE)方法来比较不同群体和案例的态度。
从医生的 25%到非正式护理者的 69%,回应率各不相同。在所有四个群体中,当患者处于终末期、表现出痛苦迹象并且在丧失能力之前已经书面提出 MAID 请求时,认为可以将 MAID 扩展至患有痴呆症的无行为能力患者的受访者比例最高。在这些情况下,这一比例从医生的 71%到非正式护理者的 91%不等。
我们在魁北克发现,大多数人支持将当前的 MAID 立法扩展至已达到终末期、表现出痛苦迹象且在有能力时已书面提出 MAID 请求的患有痴呆症的无行为能力患者。
