Q: Differential Diagnosis (DDx)
Answer:
A DDx is the ability to distinguish a disease or condition from others that present with similar
sing, symptoms or diagnostic test results
Q: How to build a DDx
Answer:
1. list your top dx first followed by other potential dx for a specific problem, but keep it problem
oriented until you have the actual dx.
2. Aggressively prioritize workup of the most likely and most harmful dx under consideration.
3. prioritize the workup of acute and reversible diseases followed by chronic and irreversible.
4. As info or data the effectively rules out a particular dx, remove that dx from the list and focus
your attention towards the remaining possibilities.
5. once the dx has been confirmed, the problem list should be diagnosis oriented rather than
problem oriented.
â—if the pt were to not respond to the tx, the pt should be re-evaluate the pt, review diagnostic data
and finally provide a summary of key data to ensure that the diagnosis is indeed correct.
Q: Likelihood Ratios
Answer:
Likelihood ratios are more helpful to make clinical decisions than sensitivty and specificity. For
a given dx test, positive likelihood ratio apply to positive results; negative likelihood ratios apply
to negative results
Q: Positive likelihood ratio
Answer:
is the likelihood that a pt with the disease test positive compared to the likelihood that a patient
without the disease test positive.
â—if a test result is positive and the positive likelihood is >1, then it is more likely than chance that
the pt has the disease. However, if the likelihood ratio for that test is <1>
the pt has the disease.
Q: Negative Likelihood Ratio
