What is evidence?
Refers to findings from clinical research
What are some advantages of evidence-based medicine?
- attempts to find interventions that work, not that it should or seem to work
- helps you find new info as it is published
- faster communication
- helps one to see flaws in others
What are some limitations of evidence-based medicine?
- focuses only if intervention works not how it works
- requires knowledge to practice effectively
- perceive it as a threat to their clinical autonomy
- many questions dont have sufficient evidence to inform clinical decision making
What are the levels of evidence starting from the bottom?
Background info / expert opinion
Case-controlled studies / case series + reports*
Cohort studies*
RCTs*
Critically-appraised individual articles**
Critically-appraised topics**
Systematic reviews**
- = unfiltered
** = filtered
All but background info/expert opinion are searched via TRIP databases
What is the orange book for?
Therapeutic equivalence
What is the red book for?

What is a key characteristic of case reports, case studies, and case series?
**lack a control or comparison group
What is a case study?
Record of a SINGLE patient
*Case report is just a singular report of one individual
**Case series = subjects share common characteristics
What is a negative from case reports, studies, and series?
Series of AE can lead to false-positive reporting and prone to reporting bias
Adverse Drug Event
Adverse Drug Reaction
Medication Error
Medication Misadventure
Which one is broad? Specific?
Broad = ADE + Misadventure
Specific = ADR + Error
What is pharmacovigilance?
Process of detecting and preventing AE of Rx
What is passive surveillance?
Spontaneous reports of ADEs, Case series, and annual reports
What is active surveillance?
Registries and pharmacoepidemiologic studies
What is dechallenge and rechallenge?
Dechallenge = suspected Rx is d/c then you monitor pt symptoms to determine whether the ADR is reduced
Rechallenge = suspected Rx is d/c then you wait for symptoms to reduce then administer the same Rx to elicit same effect
Dechallenge is essential in clinical practice unlike rechallenge. Rechallenge might be necessary in certain situations like for ABx or chemos
