循证医学:过去、现在和未来(一)

正确使用医学献解决病人问题的方法。循证医学为临床医生和病人提供了正确使用医学献解决病人问题的方法。循证医学的最佳证据来自认识到传统临床决策的错误和不足，并用循证医学方法弥补这些不足的成功范例。对循证医学内涵的认识在不断进步目前主要集中在两方面。第一，证据分级；第二，强调临床决策仅依靠证据远远不够，还需考虑病人的的价值观和意愿。当前，循证医学面临的最具吸引力的挑战是医生在对每个病人的临床决策中，充分考虑到病人的需求和意愿。

Evidence-based Medicine:Past, Present and Future (Ⅰ)

Evidence-based medicine (EBM) offers clinicians and patients approaches to optimal use of the medical literature in solving patients, problems. The best evidence for EBM comes from examples of how traditional decision-making approaches have gone wrong, and how evidence-based approaches can remedy the problems.Thinking about the nature of EBM has evolved, and now focuses on two elements. First, EBM posits a hierarchy of evidence. Second, EBM emphasizes that evidence is never sufficient for making decisions, which always requires consideration of values and preferences. Efficiently integrating patients, values and preferences into individual decision-making represents the most interesting challenge facing EBM.
