5 main types of foreground clinical qs

Therapy: Determining the effect of interventions on patient important outcomes

Harm: Ascertaining the effects of potentially harmful agents on patient important outcomes

Differential Diagnosis: In patients with a particular clinical presentation, establishing the frequency of the particular disorder

Diagnosis: Establishing the power of a test to differentiate those with and without a target condition or disease

Prognosis: Estimating a patient’s future course if we do nothing

2

Disease oriented evidence (DOE)

Studies that address factors such as organ function or biochemical levels in the blood. (i.e., surrogate outcomes)

3

Patient Oriented Evidence (POE)

Information, based on good science, that tells clinicians that what they do
helps patients live longer and/or better lives (i.e., patient important outcomes)

4

How to tell the difference?

– Ask yourself: “Can a patient feel the outcome?”
– If the answer is “No” then it is a surrogate marker

eg. lower bp infers lower mortality
