"Life-ending acts without explicit patient request," as identified in robust international studies, are central in current debates on physician-assisted dying. Despite their contentiousness, little attention has been paid to their actual characteristics and to what extent they truly represent nonvoluntary termination of life.
We analyzed the 66 cases of life-ending acts without explicit patient request identified in a large-scale survey of physicians certifying a representative sample of deaths (n = 6927) in Flanders, Belgium, in 2007. The characteristics we studied included physicians' labelling of the act, treatment course and doses used, and patient involvement in the decision.
In most cases (87.9%), physicians labelled their acts in terms of symptom treatment rather than in terms of ending life. By comparing drug combinations and doses of opioids used, we found that the life-ending acts were similar to intensified pain and symptom treatment and were distinct from euthanasia. In 45 cases, there was at least 1 characteristic inconsistent with the common understanding of the practice: either patients had previously expressed a wish for ending life (16/66, 24.4%), physicians reported that the administered doses had not been higher than necessary to relieve suffering (22/66, 33.3%), or both (7/66, 10.6%).
Most of the cases we studied did not fit the label of "nonvoluntary life-ending" for at least 1 of the following reasons: the drugs were administered with a focus on symptom control; a hastened death was highly unlikely; or the act was taken in accordance with the patient's previously expressed wishes. Thus, we recommend a more nuanced view of life-ending acts without explicit patient request in the debate on physician-assisted dying.
在有力的国际研究中所确定的“未经患者明确请求的结束生命行为”,是当前关于医生协助死亡辩论的核心内容。尽管这些行为存在争议,但对于其实际特征以及它们在多大程度上真正代表非自愿的生命终结,却很少有人关注。
我们分析了2007年在比利时弗拉芒地区对开具具有代表性死亡样本证明(n = 6927)的医生进行大规模调查中所确定的66例未经患者明确请求的结束生命行为。我们研究的特征包括医生对该行为的界定、治疗过程和所用剂量,以及患者在决策中的参与情况。
在大多数情况下(87.9%),医生将他们的行为界定为症状治疗而非结束生命。通过比较所用阿片类药物的组合和剂量,我们发现这些结束生命行为类似于强化的疼痛和症状治疗,与安乐死截然不同。在45例中,至少有1个特征与对该行为的通常理解不一致:要么患者此前曾表达过结束生命的愿望(16/66,24.4%),要么医生报告所给予的剂量未高于缓解痛苦所需的剂量(22/66,33.3%),或者两者皆有(7/66,10.6%)。
我们研究的大多数案例不符合“非自愿结束生命”的标签,原因至少如下之一:给药的重点是症状控制;加速死亡极不可能;或者该行为是根据患者此前表达的愿望实施的。因此,在关于医生协助死亡的辩论中,我们建议对未经患者明确请求的结束生命行为持更细致入微的观点。
