摘要临终医疗决策是终末期患者治疗照护过程中所面临的一个重要问题，其决策情况复杂，影响因素众多。前景理论是重要决策理论之一，其认为个人基于参考点位置不同，会有不同的风险态度，从而做出不同的临终治疗选择；而参考点选择因人而异，受个体的特征、认知、经验、心理特质、所处社会环境等多方面影响。故本文基于前景理论，从个人、心理、社会环境3个方面对终末期患者的临终决策偏好及影响因素进行综述，以期为提高终末期患者的照护质量提供参考。

abstractsDecision-making for end-of-life care is an important problem faced by end-stage patients in the process of treatment and care. The decision-making is complex and there are many influencing factors. Prospect theory is one of the important decision-making theories, which believes that individuals will have different risk attitudes based on different reference point locations, so as to make different end-of-life treatment choices. The selection of reference points varies from person to person, and is affected by individual characteristics, cognition, experience, psychological characteristics, social environment and so on. Based on the prospect theory, this paper summarizes the end-of-life decision-making preferences and its influencing factors in end-stage patients from three aspects of personal, psychology and social environment, in order to provide reference for improving the quality of care of end-stage patients.
