以色列耶路撒冷希伯来大学Alexander Avidan研究小组的一项最新研究,分析了从1999年到2016年,欧洲重症监护病房的临终行为的变化。这一研究成果发表在2019年11月5日出版的国际学术期刊《美国医学会杂志》上。

据悉,世界各地的重症监护病房(ICU)每天都会做出临终决定,但这些决定可能会随着时间的推移而改变。

1999-2000年,研究组曾在欧洲的22个ICU进行了一项前瞻性的观察研究。2015年9月至2016年10月,研究组再次对这22个ICU连续6个月期间的死亡或限制生命维持治疗的患者进行分析。每位患者均随访至死亡或限制治疗后2个月。

2015-2016年间,ICU中1785名死亡或限制延长生命治疗的患者被纳入研究,中位年龄为70岁,显著大于1999-2000年组中的2807名患者(67岁),但两组患者的性别比例相差不大。

2015-2016年组限制治疗的患者占89.7%,显著高于1999-2000年组(68.3%),两组中拒绝延长生命治疗的患者占比分别为50%和40.7%,撤销延长生命治疗占比分别为38.8%和24.8%,差异均具有统计学意义。

2015-2016年组心肺复苏(CPR)失败率、脑死亡率、主动缩短死亡过程率分别为6.2%、4.1%和1.0%,均显著低于1999-2000年组(22.4%、9.3%和2.9%)。2015-2016年组延长生命治疗患者的死亡率为10.3%,显著低于1999-2000年组(31.7%)。

总之,对于欧洲22个ICU中限制治疗或死亡的患者,2015-2016年与1999-2000年相比,限制延长生命治疗的患者显著增多,而选择延长生命治疗患者的死亡率显著降低。这表明欧洲ICU的临终方案发生了变化。这项研究仍有一定的局限性,它并未统计那些延长生命治疗后存活下来的ICU患者。

Abstract: 

Importance  End-of-life decisions occur daily in intensive care units (ICUs) around the world, and these practices could change over time.

Objective  To determine the changes in end-of-life practices in European ICUs after 16 years.

Design, Setting, and Participants  Ethicus-2 was a prospective observational study of 22 European ICUs previously included in the Ethicus-1 study (1999-2000). During a self-selected continuous 6-month period at each ICU, consecutive patients who died or had any limitation of life-sustaining therapy from September 2015 until October 2016 were included. Patients were followed up until death or until 2 months after the first treatment limitation decision.

Exposures  Comparison between the 1999-2000 cohort vs 2015-2016 cohort.

Main Outcomes and Measures  End-of-life outcomes were classified into 5 mutually exclusive categories (withholding of life-prolonging therapy, withdrawing of life-prolonging therapy, active shortening of the dying process, failed cardiopulmonary resuscitation [CPR], brain death). The primary outcome was whether patients received any treatment limitations (withholding or withdrawing of life-prolonging therapy or shortening of the dying process). Outcomes were determined by senior intensivists.

Results  Of 13?625 patients admitted to participating ICUs during the 2015-2016 study period, 1785 (13.1%) died or had limitations of life-prolonging therapies and were included in the study. Compared with the patients included in the 1999-2000 cohort (n = 2807), the patients in 2015-2016 cohort were significantly older (median age, 70 years [interquartile range {IQR}, 59-79] vs 67 years [IQR, 54-75]; P < .001) and the proportion of female patients was similar (39.6% vs 38.7%; P = .58). Significantly more treatment limitations occurred in the 2015-2016 cohort compared with the 1999-2000 cohort (1601 [89.7%] vs 1918 [68.3%]; difference, 21.4% [95% CI, 19.2% to 23.6%]; P < .001), with more withholding of life-prolonging therapy (892 [50.0%] vs 1143 [40.7%]; difference, 9.3% [95% CI, 6.4% to 12.3%]; P < .001), more withdrawing of life-prolonging therapy (692 [38.8%] vs 695 [24.8%]; difference, 14.0% [95% CI, 11.2% to 16.8%]; P < .001), less failed CPR (110 [6.2%] vs 628 [22.4%]; difference, −16.2% [95% CI, −18.1% to −14.3%]; P < .001), less brain death (74 [4.1%] vs 261 [9.3%]; difference, −5.2% [95% CI, −6.6% to −3.8%]; P < .001) and less active shortening of the dying process (17 [1.0%] vs 80 [2.9%]; difference, −1.9% [95% CI, −2.7% to −1.1%]; P < .001).

Conclusions and Relevance  Among patients who had treatment limitations or died in 22 European ICUs in 2015-2016, compared with data reported from the same ICUs in 1999-2000, limitations in life-prolonging therapies occurred significantly more frequently and death without limitations in life-prolonging therapies occurred significantly less frequently. These findings suggest a shift in end-of-life practices in European ICUs, but the study is limited in that it excluded patients who survived ICU hospitalization without treatment limitations.
