Premature closure
Jumping to conclusions.
Diagnostic momentum
Jumping to conclusions.
Anchoring bias
Ignoring observations that conflict w proposed diagnosis.
Confirmation bias
Ignoring observations that conflict w proposed diagnosis.
Availability bias
‘The last case you saw.’
Memorability bias
‘The last case you saw.’
Framing bias
‘Overly influenced by the context.’
Affective bias
Emotional influence.
Sensitivity
Remember snip
Proportion w the disease who test positive.
Specificity
Remember spin
Proportion w/out the disease who test negative.
What is a likelihood ratio?
Expresses how many times more or less likely a test result is to be found in diseased populations, compared to non-diseased populations.
Odds = ___/___ re probability
Probability/1-pr
Probability = ___/___ re odds
Odds/1+odds
What is the point of a nomogram?
Allows conversion btw pre-test & post-test probability w/out having to calculate the odds on the way through.
LR+
Probability +ve test in a person w disease/probability of a +ve test in person w/out disease (sensitivity/1-specificity)
