Abstract
PURPOSE: Intensive care unit patients rarely have decisional capacity and often surrogates make clinical decisions on their behalf. Little is known about how surrogate characteristics may influence end-of-life decision making for these patients. This study sought to determine how surrogate characteristics impact physicians' approach to end-of-life decision making. METHODS: From March 2011 to August 2011, a survey was fielded to 1000 randomly sampled critical care physicians using a modified Dillman approach. The survey included a hypothetical vignette to examine how physicians' approach varied based on patient age, patient-surrogate relationship, surrogate-staff relationship, basis for surrogate's stated preferences, and surrogate's understanding of patient's condition. Outcomes included physicians' beliefs regarding (1) appropriateness of cardiopulmonary resuscitation (CPR); (2) appropriate locus of decision making for the patient; (3) degree to which a physician would try to influence a surrogate if disagreement was present; and (4) physician strategies to discussing end-of-life with surrogates. RESULTS: Of 922 eligible physicians, 608 (66%) participated. Across all vignettes, CPR was felt to be less appropriate and surrogates less likely to be given priority with an older rather than younger patient (15% vs 63% and 50% vs 65%, both P values <.001). Cardiopulmonary resuscitation was considered less appropriate when the surrogate-patient relationship was not close (34% vs 44%, P = .03) and the surrogate's understanding was poor (34% vs 43%, P = .05). No other surrogate characteristics examined yielded statistically significant associations. CONCLUSION: Some surrogate characteristics may modify clinicians' beliefs and practices regarding end-of-life care, suggesting the nuances of the surrogate-physician relationship and clinical decision making for critically ill patients.
