This study aimed to characterize whether and how the option of a treatment trial is discussed with surrogates in intensive care units.
We audio-recorded 72 family conferences for 72 patients at high risk for death or severe functional impairment in 5 intensive care units in San Francisco, California. We analyzed transcripts to develop a coding framework for whether and how trials were discussed.
Trials were offered in 15% of conferences. We identified 2 types: (1) time-limited trials, defined as continuing all intensive, life-sustaining treatments, with a plan to reassess after a defined time period based on prespecified clinical milestones, and (2) symptom-limited trials, defined as using basic medical care aimed at survival (rather than purely comfort-focused treatment) once ventilatory support is withdrawn, with a plan to reassess based on patient symptoms. Clinicians frequently did not inform surrogates about key elements of the trial such as criteria by which the effectiveness of the trial would be evaluated and possible next steps based on trial results.
In this cohort of critically ill patients, trials were infrequently and incompletely discussed. Additional work is needed to improve communication about treatment trials and evaluate their impact on patient and family outcomes.
本研究旨在描述在重症监护病房中,治疗试验的选择是否以及如何与代理人进行讨论。
我们在加利福尼亚州旧金山的 5 家重症监护病房对 72 名处于死亡或严重功能障碍高风险的患者进行了 72 次家庭会议的音频记录。我们分析了转录本,以制定一个用于讨论试验的编码框架,包括是否以及如何讨论试验。
在 15%的会议中提出了试验。我们确定了两种类型:(1)限时试验,定义为继续所有强化、维持生命的治疗,根据预先规定的临床里程碑,在规定的时间后重新评估;(2)症状限制试验,定义为一旦停止通气支持,使用旨在生存的基本医疗护理(而不是纯粹以舒适为中心的治疗),并根据患者症状重新评估。临床医生经常没有告知代理人有关试验的关键要素,例如评估试验效果的标准以及基于试验结果的可能下一步措施。
在本队列的危重患者中,试验很少且不完整地进行讨论。需要进一步努力改善关于治疗试验的沟通,并评估其对患者和家属结局的影响。
