Introduction Flashcards
Clinical reasoning types
- probabilistic
- causal
- case-based
- narrative
Probabilistic reasoning
assessing likelihood of a clinical hypothesis
Causal Reasoning
cause and effect relationships of variables.
Case-based Reasoning
based on experience + research literature (script)
Narrative
what does the pt tell you?
Experts rely on what type of problem solving method?
Intuitive
Novice clinicians rely on what type of problem solving method?
Analytical
Reducing uncertainty methods
- Bayes theorem + Fagan’s Nomogram
- QUADAS tool
- Elimination strategy
- Confirmation strategy
- Discrimination strategy
- Ockham’s razor
- Hickam’s Dictum
Elimination Strategy
Seeking data to reduce suspicion of unlikely hypotheses
Confirmation Strategy
Seeking data to support a highly likely hypotheses
Discrimination strategy
seeking information to discriminate between likely hypotheses
A diagnosis requires…
- Coherency
- Adequacy
- Parsimonous nature
No-fault error
errors in which no clinician could have made the diagnosis
System Errors
occur due to technical failures or organizational failures
Cognitive errors
subconscious errors in our thinking processes
Aggregate Bias
belief that aggregated data (CPGs) don’t apply to your pt population
Anchoring
lock into salient features in pt’s initial presentation too early in diagnostic process.
Commission Bias
belief that pt requires intervention to heal
Omission Bias
Belief that no intervention is more beneficial
Confirmation bias
tendency to look for confirming evidence to support a diagnosis
Outcome bias
opt for diagnosis with better prognosis
Overconfidence Bias
a universal tendency to believe we know more than we do.
Premature closure
tendency to apply premature closure to decision making process once diagnosis is verified
Search satisfying
universal tendency to stop search once diagnosis is found.
