The value of good end-of-life (EOL) care could be underestimated if its effects are assessed using the standard metric of quality-adjusted survival, especially if the time horizon is limited to the duration of the EOL care. This issue is particularly problematic in the intensive-care unit (ICU) where death is frequent, care is difficult, and costs are high.
The objectives of this study were to test whether people would trade healthy life expectancy for better EOL care, to understand how much life expectancy they would trade relative to domains of good care, and to determine the association of respondent characteristics to time traded.
We used a computerized survey instrument describing hypothetical patient experiences in the ICU used to assess attitudes of a general population sample (n = 104) recruited in Pittsburgh, Pennsylvania.
We used life expectancy traded (from a baseline of 80 healthy years followed by a 1-month fatal ICU stay) for improving ICU care in 4 domains: pain and discomfort, daily surroundings, treatment decisions, and family support.
Three fourths of respondents (n = 78) were prepared to shorten healthy life for better EOL care. Median time traded in individual domains ranged from 7.2 to 7.7 months overall and 9.6 to 11.4 months when restricted to those willing to trade. Median time traded for improvement in all domains was 8.3 months overall and 24.0 months by those willing to trade. In multivariable analyses, respondents who were older, nonwhite, or had children traded significantly less time, whereas those who did not perceive the ICU to be a caring environment traded more time.
Good EOL care is highly valued, both in terms of medical and nonmedical domains, as suggested by previous work and confirmed by our data showing respondents trading quantities of healthy life several times longer than the duration of the EOL period itself. The considerable interperson variation highlights the importance of soliciting individual preferences about EOL care.
如果使用质量调整生存的标准指标来评估临终(EOL)护理的效果,尤其是如果时间范围仅限于临终护理的持续时间,那么良好的临终护理的价值可能会被低估。在重症监护病房(ICU),这个问题尤为突出,因为在那里死亡频繁、护理困难且成本高昂。
本研究的目的是测试人们是否会用健康预期寿命来换取更好的临终护理,了解相对于优质护理的各个领域,他们愿意交换多少预期寿命,并确定受访者特征与交换时间之间的关联。
我们使用了一种计算机化调查工具,描述了重症监护病房中假设的患者经历,以评估在宾夕法尼亚州匹兹堡招募的普通人群样本(n = 104)的态度。
我们使用为改善重症监护病房护理在四个领域所交换的预期寿命(从80年健康基线开始,随后是为期1个月的致命重症监护病房住院期):疼痛与不适、日常环境、治疗决策和家庭支持。
四分之三的受访者(n = 78)准备为了更好的临终护理而缩短健康寿命。在各个领域中,总体交换时间的中位数在7.2至7.7个月之间,而仅限于愿意交换的人时为9.6至11.4个月。所有领域改善所交换时间的总体中位数为8.3个月,愿意交换的人则为24.0个月。在多变量分析中,年龄较大、非白人或有孩子的受访者交换的时间明显较少,而那些认为重症监护病房不是一个充满关怀环境的人交换的时间更多。
正如先前的研究工作所表明的,并且我们的数据也证实了这一点,即受访者愿意用数倍于临终护理期本身时长的健康寿命来交换,这表明良好的临终护理在医疗和非医疗领域都具有很高的价值。人与人之间存在的显著差异凸显了征求个人对临终护理偏好的重要性。
