Exam 1 Flashcards
Describe non analytical clinical reasoning
Involves pattern recognition; fast & implicit
Describe analytical clinical reasoning
Evidence based; slow, deliberate and rational
Equation for sensitivity
sens = a/(a+c)
a = true + (finding present in disease pts) c = false - (finding absent in disease pts)
a+c = n1 (total disease pts)
A ______ sensitivity rules _____ disease
NEGATIVE sensitivity rules OUT disease
“SnOUT”
Equation for specificity
Spec =d/(b+d)
b = false + (patient without dz WITH finding) d = true - (patient without dz WITHOUT finding)
n2 = b + d (total patients without dz)h
Equation for positive likelihood ratio
+LR = sens/(1-spec)
A high +LR means a high likelihood of dz
A positive LR value of 2 means ___%of having dz
+15% of dz
A positive LR value of 5 means ___%of having dz
+30% of dz
A positive LR value of 10 means ___%of having dz
+45% of dz
Equation for negative likelihood ratio
- LR = (1-sens)/spec
A smaller negative LR means less like hood of having dz
A negative LR value of 0.5 means ___%of having dz
-15% chance of having dz
A negative LR value of 0.2 means ___%of having dz
-30% chance of having dz
A negative LR value of 0.1 means ___%of having dz
-45% chance of having dz
A ____ specificity rules _____ dz
POSITIVE specificity rules IN disease
“SpIN”
