Chinese and U.S. internists adhere to different ethical standards.

<bold>Objective: </bold>To determine whether internists in the United States and China have different ideas and behaviors regarding informing patients of terminal diagnoses and HIV/AIDS, the role of the family in end-of-life decision making, and assisted suicide.<bold>Design: </bold>Structured questionnaire of clinical vignettes followed by multiple choice questions.<bold>Setting: </bold>University and community hospitals in San Francisco and Beijing, China.<bold>Subjects: </bold>Forty practicing internists were interviewed, 20 in China and 20 in the United States.<bold>Measurements and Main Results: </bold>Of the internists surveyed, 95% of the U.S. internists and none of the Chinese internists would inform a patient with cancer of her diagnosis. However, 100% of U.S. and 90% of Chinese internists would tell a terminally ill patient who had AIDS, rather than advanced cancer, about his diagnosis. When family members' wishes conflicted with a patient's preferences regarding chemotherapy of advanced cancer, Chinese internists were more likely to follow the family's preferences rather than the patient's preferences (65%) than were the U.S. internists (5%). Thirty percent of U.S. internists and 15% of Chinese internists agreed with a terminally ill patient's request for sufficient narcotics to end her life.<bold>Conclusions: </bold>We found significant differences in clinical ethical beliefs between internists in the United States and China, most evident in informing patients of a cancer diagnosis. In general, the Chinese physicians appeared to give far greater weight to family preferences in medical decision making than did the U.S. physicians. [ABSTRACT FROM AUTHOR]
