FPGEE Drug Information 5 — Questions and Answers
Question 1: Which component of the PICO framework represents the standard treatment or comparator group?
- P – Patient/Population
- I – Intervention
- C – Comparison (Correct answer)
- O – Outcome
Correct answer: C – Comparison
In the PICO framework, 'C' stands for Comparison, representing the alternative treatment or placebo against which the intervention is evaluated.
Question 2: A pharmacist is asked whether a drug causes QT prolongation. Which specialized resource is BEST suited to answer this?
- CredibleMeds (AzCERT QTDrugs List) (Correct answer)
- Epocrates
- Micromedex NeoFax
- Red Book
Correct answer: CredibleMeds (AzCERT QTDrugs List)
CredibleMeds (maintained by AzCERT) maintains the most comprehensive, evidence-based risk categorization for drug-induced QT prolongation.
Question 3: What is publication bias in the context of drug information evaluation?
- Authors publishing in biased journals
- Preferential publication of studies with positive or statistically significant results (Correct answer)
- Bias introduced by industry-funded research
- Selective reporting of adverse effects
Correct answer: Preferential publication of studies with positive or statistically significant results
Publication bias is the tendency for studies with positive or statistically significant results to be published more frequently than those with null or negative results.
Question 4: Which measure of central tendency is MOST affected by outliers in a dataset?
- Mode
- Median
- Mean (Correct answer)
- Range
Correct answer: Mean
The mean is most sensitive to outliers because it incorporates the actual value of every data point in its calculation.
Question 5: A drug information response recommends a lower dose for a patient with renal impairment. Which primary resource BEST supports this recommendation?
- Lexicomp Renal Disease Dosing or the FDA package insert renal dosing section (Correct answer)
- AHFS index
- Micromedex drug identification
- Briggs' Pregnancy and Lactation
Correct answer: Lexicomp Renal Disease Dosing or the FDA package insert renal dosing section
The FDA package insert's renal dosing section and Lexicomp's renal disease dosing guidance provide the most directly applicable evidence-based recommendations for dose adjustment.
Question 6: What is the difference between a systematic review and a narrative review in drug information?
- Systematic reviews include only RCTs; narrative reviews include all study types
- Systematic reviews use explicit, reproducible search methods; narrative reviews reflect expert opinion without predefined methodology (Correct answer)
- Narrative reviews are more reliable for clinical decision-making
- Systematic reviews are shorter and less detailed than narrative reviews
Correct answer: Systematic reviews use explicit, reproducible search methods; narrative reviews reflect expert opinion without predefined methodology
Systematic reviews use transparent, predefined search strategies and inclusion/exclusion criteria, minimizing bias, while narrative reviews are less structured and more subject to author bias.
Question 7: Which type of pharmacovigilance study is MOST useful for detecting rare adverse drug reactions that were not identified in pre-marketing clinical trials?
- Phase II clinical trials
- Phase III randomized controlled trials
- Post-marketing surveillance (Phase IV) studies (Correct answer)
- Phase I dose-escalation studies
Correct answer: Post-marketing surveillance (Phase IV) studies
Phase IV (post-marketing surveillance) studies monitor drugs in large real-world populations after approval, making them most capable of detecting rare adverse events not seen in smaller pre-marketing trials.
