  17. Databases

  18. Needle in a haystack • Huge growth in the number of medical/nursing/allied health journals • Large number of databases indexing different collections of journals • 15 million records in Medline with 400,000 added per year • Massive variance in quality between publications/articles • Where to start?

  19. Databases • Two types of database: filtered & unfiltered • Filtered resources: databases of secondary literature – systematic reviews, guidelines, critically appraised individual articles • Unfiltered resources: contain the above plus research articles, case reports, letters, editorial material

  20. Filtered resources • Cochrane Database of Systematic Reviews • Cochrane Central Register of Controlled Trials • Database of Abstracts of Reviews of Effect (DARE) • National Guidelines Clearinghouse (www.guidelines.gov) • ACP Journal Club

  21. Unfiltered resources • Medline • Embase • Cinahl • PsycInfo • British Nursing Index • AMED

  22. Searching the databases: 10 top tips • Plan your search before you start • What do you need to know? • What do you not want – limits • What sort of material do you want to find? • Do you want everything or just a few general articles?

  23. Searching the databases: 10 top tips • Write things down • Break your search down into topics • Brainstorm the different words/phrases/acronyms/abbreviations that might be used to describe these topics • Think about what databases you might search – write that down too

  24. Searching the databases: 10 top tips • Use Subject Headings • “Labels” applied to all articles about a particular topic • Makes your search more specific… • …if you find the right ones • Sets of Subject Headings differ between databases

  25. Searching the databases: 10 top tips • Use Key Words • “free text” searching • If there are no relevant Subject Headings • If you need to make sure you don’t miss anything • Less specific search – more sensitive

  26. Searching the databases: 10 top tips • Use shortcuts when keyword searching • Truncation (*) – for words with the same root but different endings • Wildcard (?) – for words with different spellings • Adjacency (ADJ, ADJ3) – to specify that words should be next to/near each other

  27. E.g. searching for articles about children Some possible words: child, children, childhood, infant, infants, infantile, paediatric, paediatrics, paediatrician, pediatric, pediatrics, pediatrician Search for: child* or infant* or p?ediatr*

  28. Searching the databases: 10 top tips • Combine searches using OR • For searches about the same topic • To broaden your search • To get a bigger set of results • Usually near the beginning of a search

  29. Searching the databases: 10 top tips • Combine searches using AND • For searches about different topics • To narrow your search • To get a smaller set of results • Usually near the end of a search

  30. AND You want both terms to be present in the results: cheese AND pickle OR You want either terms to be present in the results: apples OR pears Using AND and OR AND OR

  31. Searching the databases: 10 top tips • Use Limits to narrow your search to… • A particular publication date(s) • A specific age group • A particular publication type • A particular language (eg English)

  32. Searching the databases: 10 top tips • Use Filters to… • Narrow your search to a particular level of evidence (RCTs, Systematic Reviews) • Clinical Queries filters – from Limits • Other filters saved as Expert Searches

  33. Searching the databases: 10 top tips • If at first you don’t succeed… • Read back through your search strategy • Check for spelling errors, AND instead of OR • Think about ways of describing your topic you may have missed • Did you narrow your search too much? Not enough? • Ask a librarian – we’re happy to help!

  34. Clinical Query filters • Filters by a specific clinical study category, eg therapy, diagnosis • Filters for high level of evidence • Options of sensitive or specific filter • Based on filters developed by Haynes et al (BMJ 2005)

  35. Expert Search Filters • Accessed via OVID personal account (see filters handout) • Pre-saved searches which can be added to your own search strategy • Available for a range of databases, sensitive/specific, systematic reviews, clinical queries

  36. Still confused? • Training available from the NHSGGC Library Network (one to one or small group) • Use the Ask a Librarian button on OVID to send your search strategy to the library team • NHSGGC Literature Search service

  37. Finding the full text

  38. Finding the full text • Knowledge Network article search via the eLibrary widget • From within the databases • Direct full text links • SFX button to search the Knowledge Network • No full text? No problem www.gglss.scot.nhs.uk

  39. Critical Appraisal A brief overview

  40. Overview • Definitions • Some types of study design • Tools and checklists

  41. What is critical appraisal? The process of systematically examining research evidence to assess its: • validity • importance • relevance before using it to inform a decision

  42. Critical appraisal: • helps us to make sense of research by using a systematic approach • helps us to interpret the methodology and results of research • allows us decide on the quality and usefulness of a published paper • allows us to make decisions about our own practice, based on evidence

  43. Why do we need to appraise articles? • not every study is of good quality • results can be misleading • publication bias • published research is not always relevant to local population and circumstances • “information overload”

  44. “Information overload” • Clinicians would have to read 17 articles per day, 365 days per year to keep up with research being published * • research is of variable quality * Source: A Booth, School of Health and Related Research, University of Sheffield, 2000

  45. Hierarchy of evidence

  46. Primary evidence Primary research studies New information, original research

  47. Case control study • epidemiological study design • used to identify causes of a condition by comparing subjects who have the condition with a “control” group, who don’t have the condition but are otherwise similar • retrospective, non-randomised

  48. Cohort study • longtitudinal or observational study • tracks population over a period of time. Provides information on eg. causation and risk of disease • cohort = a group of people who share a characteristic, eg. born on the same day or exposure to a drug • comparison group = a group of people similar to the cohort group apart from the characteristic (eg. the general population)

  49. Randomized controlled trials • a type of clinical experiment, designed to measure efficacy or effectiveness. • involves the random allocation of different interventions (treatments or conditions) to subjects. • patients are divided into two or more groups • patients are allocated randomly to different arms of the trial. If enough patients are included, groups should be comparable • the most important advantage of proper randomization is that it should eliminate selection bias
