7. Why Now?

8. Citations in MEDLINE Over Time

9. As cited in Schoolman & Lindberg, 1988 John Shaw Billings Director, National Library of Medicine 1881 “ The geometric progression of publication in medicine of the last few decades, if continued, would lead to the absurd conclusion that the time would soon come when it would require the services of everyone in the world not engaged in writing to catalogue and index the annual output of medical literature.”

19. PubMed’s Clinical Queries There are different types of clinical questions –Therapy: does compression bandaging increase the healing of venous leg ulcers compared with no compression? –Prognosis: Does having a stroke increase risk of dementia in older people? There are different types of “best evidence” for answering these different types of questions

20. “Best Evidence” for Question Type Question TypeBest Evidence TherapyIndividual randomized controlled trials PrognosisIndividual cohort studies or follow-up studies that assess morbidity, mortality or survival

21. A lit search for best evidence must include: Terminology reflecting the clinical concepts –Venous leg ulcers, compression bandaging –Stroke, dementia, elderly Terminology capturing characteristics of “best evidence” –Randomized controlled trial –Follow-up or cohort study

22. PubMed Clinical Queries (Haynes, et al) Question TypeMEDLINE Query Therapy “Clinical trial” in Title/Abstract OR clinical trials in MeSH OR clinical trial in Publication Type OR random* in Title/Abstract OR “random allocation” in MeSH OR “therapeutic use” in MeSH Subheading Prognosis Incidence in MeSH OR mortality in MeSH OR follow up studies in MeSH OR prognos* in Title/Abstract OR predict* in Title/Abstract OR course* in Title/Abstract
