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


Disease oriented evidence (DOE)

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


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)


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
