想象一下去医院看病,人工智能(AI)系统根据患者的检查数据实时自动生成治疗方案,经医生审查后,如果患者和医生皆不反对就直接执行该方案—— 这不是科幻,而是中国医学科学院血液病医院(中国医学科学院血液学研究所)信息与资源中心首席技术专家陈俊仁和姜尔烈团队的最新技术突破。近日, 上述团队在《自然·通讯》杂志发表文章,首次报道条件式自主AI开立药物处方的临床实践。 陈俊仁表示,当前AI的临床医学应用多是"辅助型AI"。好比社交平台的智能引擎推送个性化的新闻信息,辅助型的医疗AI基于患者情况生成个性化的医学 专业信息,接着医生和患者决定是否采纳该信息并共同决定如何根据AI所提供的信息制定诊治方案。 然而,随着AI迅速深入到人类日常生活的多个方面,条件式自主AI模式也越来越普遍。例如汽车驾驶导航软件不仅提供空间地图信息和实时路况,而且可 直接计算出最优驾驶路线。 研究团队认为,未来AI临床应用也可能采取条件式自主模式,即AI制定医疗方案作为默认选项,若医生和患者不否决就执行该默认方案。研究团队假设, 在满足三个条件的情况下,医生和患者更可能愿意接受使用条件式自主AI生成医疗方案:一、除了AI手段之外没有其他方法能精准判 ...
