Rationale: Although there is a growing belief that physicians should routinely provide a recommendation to surrogates during deliberations about withdrawing life support, there is a paucity of empirical data on surrogates' perspectives on this topic. Objective: To understand the attitudes of surrogate decision-makers toward receiving a physician's recommendation during deliberations about whether to limit life support for an incapacitated patient. Methods: We conducted a prospective, mixed methods study among 169 surrogate decision-makers for critically ill patients. Surrogates sequentially viewed 2 videos of simulated physician-surrogate discussions about whether to limit life support, which varied only by whether the physician gave a recommendation. Measurements: The main quantitative outcome was whether surrogates preferred to receive a physicians’ recommendation. Surrogates also participated in an in-depth, semi-structured interview to explore the reasons for their preference. Main Results: 56% (95/169) of surrogates preferred to receive a recommendation; 42% (70/169) preferred not to receive a recommendation, and 2% (4/169) felt both approaches were equally acceptable. We identified four main themes that explained surrogates' preferences, including surrogates' perceptions of physicians' appropriate role in life or death decisions and their perceptions of the positive or negative consequences of a recommendation on the physician-surrogate relationship, on the decision making process, and on long-term regret for the family. Conclusions: There is no consensus among surrogates about whether physicians should routinely provide a recommendation regarding life support decisions for incapacitated patients. These findings suggest that physicians should ask surrogates whether they wish to receive a recommendation regarding life support decisions and should be flexible in their approach to decision making.
