Withholding and withdrawal of life-sustaining treatments in intensive care Units in Asia

Abstract

IMPORTANCE: Little data exist on end-of-life care practices in intensive care units (ICUs) in Asia. OBJECTIVE: To describe physicians' attitudes toward withholding and withdrawal of life-sustaining treatments in end-of-life care and to evaluate factors associated with observed attitudes. DESIGN, SETTING, AND PARTICIPANTS: Self-administered structured and scenario-based survey conducted among 1465 physicians (response rate, 59.6%) who manage patients in ICUs (May-December 2012) at 466 ICUs (response rate, 59.4%) in 16 Asian countries and regions. RESULTS: For patients with no real chance of recovering a meaningful life, 1029 respondents (70.2%) reported almost always or often withholding whereas 303 (20.7%) reported almost always or often withdrawing life-sustaining treatments; 1092 respondents (74.5%) deemed withholding and withdrawal ethically different. The majority of respondents reported that vasopressors, hemodialysis, and antibiotics could usually be withheld or withdrawn in end-of-life care, but not enteral feeding, intravenous fluids, and oral suctioning. For severe hypoxic-ischemic encephalopathy after cardiac arrest, 1201 respondents (82.0% [range between countries, 48.4%-100%]) would implement do-not-resuscitate orders, but 788 (53.8% [range, 6.1%-87.2%]) would maintain mechanical ventilation and start antibiotics and vasopressors if indicated. On multivariable analysis, refusal to implement do-not-resuscitate orders was more likely with physicians who did not value families' or surrogates' requests (adjusted odds ratio [AOR], 1.67 [95% CI, 1.16-2.40]; P =.006), who were uncomfortable discussing end-of-life care (AOR, 2.38 [95% CI, 1.62-3.51]; P
