Title: Introduction To Databases


1
Accessing Sources Of Evidence For Practice
  • Introduction To Databases
  • Karen Smith
  • Department of Health Sciences
  • University of York

2
Introduction to Databases
  • Objectives
  • Have practical experience in using the main
    health care databases including the Cochrane
    Library, Medline, Evidence-Based Nursing
  •  
  • Have an overview of the range of databases
    available and the ability to select one which is
    relevant to your needs
  •  

3
What Is A Bibliographic Database?
  • They store details from publications which
    include journals, conferences, letters, reviews
    etc
  • The details are displayed in the form of a record
    for each item
  • Sometimes an abstract (summary) is provided
  • May also link to full text

4
What Are Databases Used For?
  • They are searchable using author name, subject,
    title and year
  • Enable you to find articles on a subject
  • They allow you to search through a much larger
    number of articles than you could by hand

5
Some Applications
  • Used to search for information to support essays
  • They are a fast way to search a large number of
    records and thus save you time

6
Some Applications Ctd
  • Used to search for information to inform research
    projects
  • Used by clinicians and patients to inform nursing
    practice and acquire up to date information on
    treatment

7
Choosing The Right Database

   
  • Selecting the right resource is crucial to
    literature searching
  • In health related topics there is a wide variety
    of different databases to choose from

8
Choosing The Right Database Ctd
  • They can offer very different information
  • Each has its strengths and weaknesses e.g. Cinahl
    is stronger than Medline in a number of areas
    e.g. nursing
  • Some focus on narrow areas of interest e.g.
    PsycINFO

9
Choosing The Right Database Ctd
  • Others focus on specific research methods e.g.
    Cochrane Library

10
Coverage
  • Each database varies in coverage
  • Some overlap with others
  • Some may be subject specific whilst others could
    be multidisciplinary

11
Examples
  • Here are some databases we recommend you use to
    research your questions and topics

12
Examples
  • Cochrane Library in particular the Cochrane
    Database of Systematic Reviews
  • Medline
  • Cinahl
  • Evidence Based Nursing Online

13
Access
  • Most databases can be accessed using Metalib
  • http//www.york.ac.uk/

Access

Cochrane Library
  • What is it?
  • The Cochrane Library is an electronic publication
    designed to supply high quality evidence to
    inform people providing and receiving care, and
    those responsible for research, teaching, funding
    and administration at all levels

16
Cochrane Library
  • Where is it?
  • http//www.library.nhs.uk/Default.aspx

17
National Library for Health
18
Cochrane Library Ctd
  • Major source, though not comprehensive
  • Complete text of reviews regularly updated
  • Reviews in progress therefore very up to date
    information.

19
Cochrane Library (Cochrane Database of Systematic
Reviews)
20
Cochrane Library Ctd
  • Key source of evidence - quality assessed reviews
    using quality criteria
  • It contains the most comprehensive and
    international collection of evidence on which
    types of health care have been shown to work and
    which need more research

21
Cochrane Library Ctd
  • It is used by researchers and clinicians
    worldwide, and increasingly by patients and their
    families
  • Provides the evidence base for many people
    involved in the preparation of health guidelines

22

23
Cochrane Library Ctd
  • The Cochrane Library consists of a regularly
    updated collection of evidence-based medicine
    databases
  • The Cochrane Database of Systematic Reviews
    (Cochrane Reviews) is one of these
  • This database contains reviews of previous
    research undertaken

24
The Cochrane Database of Systematic Reviews
  • Saves you time because the author has already
    carried out a detailed search
  • Evaluates the research using reliable methods
  • Comprehensive summary of the available evidence
    an overview

25
Cochrane Demonstration

Medline
  • Major index of 4,000 plus biomedical journals
  • Contains references and abstracts added from 1950
    onwards
  • MEDLINE's journal coverage is extensive but
    represents possibly just a third, of the number
    of biomedical journals published worldwide

27
Medline Ctd
  • Most MEDLINE records are from English language
    sources or have English abstracts, and may have
    an English
  • Take care as not all are available in
  • English
  • Available via Ovid Web Gateway.
