什么是循证医学?
证据合成 医疗决策 病人的护理
Sackett, British Medical Journal, 1996: “…[t]he conscientious,
judicious and explicit use of current best evidence in making
decisions about the care of the individual patient”
![Page 4: Bridging Evidence Based Medicine and Patient Centered Care: The Case of Localized Prostate Cancerr](https://reader034.fdocument.pub/reader034/viewer/2022042614/5597122e1a28ab47108b4674/html5/thumbnails/4.jpg)
Logic of decision-making
决策逻辑
T. Greenhalgh’s phrase: “Logic of decision-making versus the
logic of care” (J Primary Health Care, 2013)
Logic of care 护理的逻辑

Perhaps primary care providers
