In retrospective studies, estimates of hastened dying among seriously ill patients range from <2% in one national survey to as much as 20% in end-stage disease cohorts.
To examine, in prospective studies, dying patients in the months before death, in order to understand the wish to die.
Patients with advanced ALS with a high likelihood of death or need for tracheostomy within 6 months were identified. Patients were assessed monthly with an extensive psychosocial interview, including a diagnostic interview for depression. Family caregivers were interviewed on the same schedule and also after patient deaths.
Eighty patients with ALS were enrolled, 63% of eligible patients; 53 died over follow-up. Ten (18.9%) of the 53 expressed the wish to die, and 3 (5.7%) hastened dying. Patients expressing the wish to die did not differ in sociodemographic features, ALS severity, or perceived burden of family caregivers. They were more likely to meet criteria for depression, but differences were smaller when suicidality was excluded from the depression interview. Patients who expressed the wish to die reported less optimism, less comfort in religion, and greater hopelessness. Compared with patients unable to act on the wish to die, patients who hastened dying reported reduction in suffering and increased perception of control over the disease in the final weeks of life.
These findings suggest caution in concluding that the desire to hasten dying in end-stage disease is simply a feature of depression.
在回顾性研究中,对重症患者加速死亡的估计范围从一项全国性调查中的不到2%到终末期疾病队列中的高达20%。
在前瞻性研究中,对临终前数月的临终患者进行研究,以了解其求死愿望。
确定6个月内死亡可能性高或需要气管切开术的晚期肌萎缩侧索硬化症(ALS)患者。每月对患者进行一次全面的社会心理访谈评估,包括抑郁症诊断访谈。对家庭护理人员按相同时间表进行访谈,并在患者死亡后也进行访谈。
招募了80例ALS患者,占符合条件患者的63%;53例在随访期间死亡。53例中有10例(18.9%)表达了求死愿望,3例(5.7%)加速死亡。表达求死愿望的患者在社会人口学特征、ALS严重程度或家庭护理人员感知负担方面无差异。他们更有可能符合抑郁症标准,但在抑郁症访谈中排除自杀倾向后差异较小。表达求死愿望的患者报告的乐观情绪较少、宗教信仰带来的慰藉较少且绝望感更强。与无法按照求死愿望采取行动的患者相比,加速死亡的患者报告在生命的最后几周痛苦减轻且对疾病的控制感增强。
这些发现表明,在得出终末期疾病中加速死亡的愿望仅仅是抑郁症特征这一结论时应谨慎。
