  10. 1st step: framing the question

  11. 1st step: framing the question • Population:who are the relevant patients? • Intervention or exposure:what are the management strategies we want to appraise or the relevant harmful exposure we want to study? • Outcome:what are the patient-relevant consequences of the exposure in which we are interested?

  12. 2nd step: determining question type

  13. 2nd step: determining question type • Therapy:determining the effect of different treatments on improving patient function and avoiding adverse events • Harm:ascertaining the effects of potentially harmful agents on patient function, morbidity, and mortality • Diagnosis:establishing the power of an intervention to differentiate between those with and those without a target condition or disease • Prognosis:estimating the future course of a patient’s disease

  14. 1st step: example • All-purposequestion:are 1st generation DES safe? • Improved (searchable) question: • Population: patientswith acute or chroniccoronarydiseaseundergoing PCI • Intervention/Comparison:implantationof 1st generation DES (Intervention) vs BMS (Comparison) – randomizedallocation • Outcome(s):death, myocardialinfarction, stroke, repeatrevascularization, stent thrombosis, rehospitalizations, costs

  15. 2nd step: example • Therapy:which embolic protection device is more effective and safe? • Harm:what is the risk of stent fracture with DES? • Diagnosis:can I recognize which angiographically-intermediate coronary lesions are functionally significant? • Prognosis:can I predict which patients are more likely to develop stent thrombosis if treated with DES?

  19. BioMedCentral

  20. BioMedCentral • BioMedCentral is provided by a private UK company (the same that provides mRCT) • It mostly contains open access journals or conference proceedings • It may be a useful and cheap (it’s free!) starting point, but to date its content is limited • In the future however it should vastly expand

  21. Clinical Trial Results

  22. Clinical Trial Results • CTR is provided for free by C.M. Gibson (the author of the TIMI frame count and TIMI myocardial perfusion grade) • It contains pre-publication data from recent clinical trials • However, it is not comprehensive and its scope largely reflects the interests of its developer (ie coronary disease)

  23. clinicaltrials.gov

  24. clinicaltrials.gov • clinicaltrials.gov is the FDA-supported and recommended registry of prospective studies • It contains protocols of ongoing or recently completed trials • Registration in clinicaltrials.gov or similar registries is now mandatory to be eligible for publication of prospective studies in major journals

  25. DARE

  26. DARE • The Database of Abstracts of Reviews of Effectiveness is provided for free by the University of York • It contains titles and abstracts of systematic reviews of effectiveness • Each item contained (ie systematic reviews) is a very good starting point to get info on a topic • However, some hits are obsolete and no papers on prognosis, diagnosis, or pathophysiology are included to date

  27. EMBASE

  28. EMBASE • EMBASE is a comprehensive archiving site, provided for a fee by Elsevier • Its scope is similar but greater and largely non-overlapping with MEDLINE/PubMed • It may be useful for sophisticated researchers and systematic reviewers • However, it’s expensive and rarely needed, as most important papers will be already in MEDLINE/ PubMed

  29. Google Scholar

  30. Google Scholar • Scholar Google is provided for free by Google • It contains citations and direct links to abstracts or full text articles • In addition, it enables citation analysis, thus forward and backward snowballing • It’s not yet very structered, and highly relevant citations might not be included or missed because buried among thousands of non-relevant ones

  31. MEDSCAPE

  32. MEDSCAPE • A freely surfable website providing disparate content, now owned by the WebMD company • The Cardiology section is often updated and may provide recent data on trials or other news • It is not developed or maintained systematically, and thus lacks comprehensiveness

  33. mRCT

  34. mRCT • The meta Register of Controlled Trials is a freely searchable website containing data on registered trials • It is provided by the owner of BioMedCentral • It’s a good source on recent or ongoing (thus unpublished) trials • While interesting for the clinical researcher or meta-analyst, it’s scope is limited to RCT

  35. PubMed

  36. PubMed • PubMed is the web (and free) version of MEDLINE (provided by the US National Library of Medicine) • It contains data on articles printed every day in several thousands medical journals around the world, even if there is some bias toward US and English-language publications • It is reasonably comprehensive and sophisticated, especially for the expert user • Nonetheless, many papers can still be missed by the MEDLINE indexers, and using PubMed requires some expertise

  37. PubMed: tips and tricks • There are 4 basic ways to search PubMed: • Free text searches • Searches with descriptors (Medical Subject Headings, MeSH) • Clinical queries (specific filters for studies or topics) • Limits (enable the searcher to select several characteristics, such as language, article type, study type, and so forth) • History • The ideal search combines one or more of such instruments to obtain precise and concise answers to the clinical question

  44. The Cochrane Collaboration

  45. The Cochrane Collaboration • The Cochrane Collaboration provides abstracts of systematic reviews for free and full texts and additional services for a fee • It contains the most rigorous systematic reviews available to date on treatment • No comprehensive systematic reviews are yet available for other topics • Many reviews, while highly valid and pertinent, might be outdated because of infrequent updates

  46. UpToDate

  47. UpToDate • UpToDate is provided for a fee by an American company • It provides qualitative reviews of most topics, with the specific features that reviews are updated very frequently • No strict methodology for review production or update is enforced • In addition, it might seem superficial and not detailed enough for experts of a topic

  48. WebMD

  49. WebMD • WebMD is a comprehensive website for healthcare professional, that can be accessed upon fee subscription • It is relatively comprehensive but unstructured • Resembles (albeit with less cardiovascular focus) www.crtonline.org, www.medscape.com, www.theheart.org, and www.tctmd.com

  50. Web of Science
