BackgroundIn ICUs, many patients are unable to participate in decision-making regarding life-sustaining treatments. This study evaluated the opinions of family members about family and physician participation in life-sustaining treatment decisions and examined factors that influence those decisions.MethodsThis was a prospective exploratory observational study that used convenience sampling. Inquiry interviews were conducted over a 3-year period, with 126 family members (out of 303 potential participants) of patients with acute-on-chronic respiratory failure, who had been admitted to the respiratory ICU and were dependent on invasive or noninvasive mechanical ventilation. Patients of ≤ 18 years old, with a stay of < 3 days, and oncologic patients were excluded.ResultsNinety-eight percent (123/126) of the participant family members had an opinion about their involvement in decision-making about life-sustaining treatments. Physician choice was preferred by 54/123 (44%), 55/123 (45%) wished to share the decision with the physician, and 14/123 (11%) wished the family to decide. All the patients were incompetent at the time of inquiry. Autonomy prior to admission to the respiratory ICU influenced the decision.ConclusionsA majority of the families relied on physicians to help in the decision-making process about life-sustaining treatments in patients with acute-on-chronic respiratory diseases. From the family's point of view, the principle of autonomy can be exercised by delegating the decision-making process to the physician. To assume a uniform ethical conduct is to antagonize the definition of ethics.
