This is from Wikipedia:
In quantum mechanics, the uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental lower bound on the precision with which certain pairs of physical properties of a particle, such as position x and momentum p, can be simultaneously known. The more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa.
Dr. Werner Heisenberg came up with this in 1927. I will now change this to relate it to healthcare and quality indicators.
In healthcare, the uncertainty principle is the conflict that occurs when you believe measuring a few quality indicators of a patient will predict the rest of the care given to patient. Unfortunately, the more precisely you care for some aspects of a patient’s health the less precisely you care for other parts, and vice versa.
This is still a work in progress. Please feel free to rework in the comment section so that I can get this right.
