The Eighteen Foundational Postulates
Postulate 6 Knowledge Principle
Statement
Medical decisions SHALL be interpreted in the context of the medical knowledge available at the time of the decision.
Definition
Medical Knowledge is the body of medically relevant knowledge, understanding, methods, evidence, and established practice available to a medical professional at a given point in time.
The Knowledge Principle requires that medical decisions and diagnostic assessments be considered in relation to the knowledge that was actually available at the relevant time.
Principle
A medical decision SHALL be assessed against the state of medical knowledge available at the time it was made, rather than solely against knowledge acquired later.
Later developments in medical knowledge may change the interpretation of a medical condition, but they SHALL NOT automatically be used to judge an earlier decision as though that later knowledge had already been available.
