Decision-making preferences of advanced cancer Hispanic patients from the United States and Latin America.

9063 Background: To determine whether preferences in frequency of passive decision making differ between Hispanic patients from Latin America (HLA) and Hispanic-American (HA) patients. Methods: We conducted a survey of advanced cancer Hispanic patients referred to outpatient palliative care clinics in the U.S, Chile, Argentina, and Guatemala. Information on demographic variables, PS,andMarin Acculturation Assessment Tool (only U.S. patients) was collected. Decision-making preference was evaluated by the decision-making assessment tool. Results: A total of 387 patients with advanced cancer were surveyed: 91 (24%) in the US, 100 (26%) in Chile, 94 (25%) in Guatemala, and 99 (26%) in Argentina. Median age was 59 years, and 61% were female. HLA preferred passive decision-making strategies significantly more frequently with regard to involvement of the family (24% versus 10%, p=0.009) or the physician (35% versus 26%, p<0.001), even after controlling for age and education (OR 3.8, p<0.001 for physician and 2.4...
