Evidence-based medicine (EBM) is the conscientious and judicious use of the best evidence available collected from clinical trials, guidelines, and consensus statements. This article provides simple ways to practice EBM using five steps (assess the patient, ask a clearly focused clinical question, acquire the best evidence available from the medical literature, appraise the evidence, and apply the evidence to patient care) and how to execute each step properly, multiple examples of how to apply EBM to patient care, and examples of how to apply the PICO mnemonic (patient, intervention, comparison, and outcome) to the process of EBM.
循证医学（EBM）是指审慎、明智地运用从临床试验、指南及共识声明中收集到的最佳证据。本文提供了运用循证医学的简单方法，包括五个步骤（评估患者、提出明确聚焦的临床问题、从医学文献中获取最佳可用证据、评估证据以及将证据应用于患者护理）以及如何正确执行每个步骤，还列举了多个将循证医学应用于患者护理的实例，以及如何在循证医学过程中运用PICO记忆法（患者、干预措施、对照和结果）。
