PH10.{1-2,13} | PH10.{1-2,13} | Drug Information Appraisal and Promotional Literature Critique — SDL Guide — Summary & Reflection

KEY TAKEAWAYS

Drug information sources are classified as primary (original research), secondary (indexed databases and systematic reviews), and tertiary (textbooks and formularies). Each tier has different strengths, limitations, and appropriate use cases. Critical appraisal of any drug information — including promotional literature — requires: PICO framing, bias identification, statistical literacy (converting RRR to ARR and NNT), and conflict-of-interest evaluation. Promotional literature and pharmaceutical representative interactions require a structured professional approach; prescribers must cross-reference all promotional claims against independent sources before incorporating them into prescribing decisions. The NMC regulations and WHO Good Prescribing guidelines provide the professional and ethical framework for managing industry interactions. The core habit to develop is automatic conversion of relative to absolute risk measures before assessing the clinical value of any new drug claim.

REFLECT

Think about the last time you or someone you observed made a prescribing or recommendation decision based on information from a single source. What was that source? Was it promotional? Independent? Current? If you could re-run that decision with the appraisal framework you have now, would the outcome differ? Consider also: what institutional systems (hospital formulary, drug information centres, independent CME) protect prescribers from information bias — and where are the gaps in your current training environment?
