2WHAT IS THE COCHRANE LIBRARY
The Cochrane Library is the single most reliable
source for evidence on the effects of healthcare.
Health care in the 21st Century relies not only
on individual medical skills, but also on the
best information on the effectiveness of each
intervention being accessible to practitioners,
patients, and policy makers. This approach is
sometimes known as evidence-based medicine.
3The Cochrane Library is designed to provide
information and evidence to support decisions
taken in health care and to inform those
receiving care.
4THE COCHRANE COLLABORATION
Wiley publishes the Cochrane Library for the
Cochrane Collaboration
- Structure - established as an international
organisation in 1993, registered as a charity in
the U.K. - Aim - to help people make well-informed decisions
about health care. - How - by preparing and maintaining, and promoting
access to, systematic reviews of the effects of
healthcare interventions. - Publishing Output The Cochrane Library
5WHAT IS THE COCHRANE LIBRARY?
The Cochrane Library is a collection of 7 main
databases and 1 additional databases that
describe Cochrane as an organization. These are
- The Cochrane Database of Systematic Reviews
(CDSR) - The Cochrane Database of Reviews of Effects
(DARE) - The Cochrane Central Register of Controlled
Trials (CENTRAL) - The Cochrane Database of Methodology Reviews
(CDMR) - Health Technology Assessment Database (HTA)
- NHS Economic Evaluation Database (NHS EED)
- THE COCHRANE METHODOLOGY REGISTER (CMR)
- About The Cochrane Collaboration and the Cochrane
Collaborative Review Groups
6The Cochrane Database of Systematic Reviews (CDSR)
What is a Systematic Review?
The authors of a systematic review identify an
intervention for a specific disease or other
problem in health care, and then ask whether or
not this intervention works. In order to do this
they locate, appraise and synthesise evidence
from as many relevant scientific studies as
possible. They summarise conclusions about
effectiveness, and provide a unique collation of
the known evidence on a given topic, so that
others can easily review the primary studies for
intervention.
7The Cochrane Database of Systematic Reviews (CDSR)
Whats so important about it?
Reviews address clearly formulated questions such
as does fluoride help prevent tooth decay in
children or can antibiotics help in alleviating
the symptoms of sore throat. Comprehensive and
explicit methods are used to track down, select
and determine the quality of relevant research.
This includes searches for unpublished and
non-English records to provide as complete a
picture as possible to try to answer the question
considered. A diagrammatic analysis is also
provided in the form of an odds-ratio diagram.
These diagrams reveal, at a glance, whether a
treatment is beneficial or not.
8The Cochrane Database of Systematic Reviews (CDSR)
What sort of healthcare questions are addressed?
What magnitude of risk reduction when a patient
with Coronary Heart Disease stops smoking?
People who quit smoking after a heart attack or
cardiac surgery reduce their risk of death by at
least one third.
Does the use of hydrolysed formulas for infant
feeding prevents allergy and food intolerance?
When babies are not exclusively breastfed, using
hydrolysed infant formulas instead of ordinary
cow's and soy milk formulas can reduce allergies
in babies and children.
Does having a friend for support present during
labour and childbirth impact on a womans
experience?
Yes. Continuous labour support reduces a woman's
likelihood of having pain medication, increases
her satisfaction and chances for 'spontaneous'
birth, and has no known risks.
9The Cochrane Database of Systematic Reviews (CDSR)
How large is the database?
- More than 2435 Full Reviews
- More than 1606 Protocols (Reviews in
progress)
10- The Cochrane Database of Reviews of Effect
(DARE) - Contains critical assessments and and structured
abstracts of reviews. - Must meet a minimum quality criteria.
- Cover topics yet to be covered in CDSR.
- For Cochrane reviewers and researchers wanting
information on reviews of heath care effects from
sources outside the Cochrane Library
- The Cochrane Central Register of Controlled
Trials - (CENTRAL)
- Contains a register of studies which may be
relevant for inclusion in Cochrane reviews - Worlds largest database of randomly controlled
trials - For Cochrane reviewers needing to identify
studies for a Cochrane review and researchers
wishing to identifies studies in a different
medical disciplines.
11- The Cochrane Database of Methodology Reviews
(CDMR) - Contains Methodology reviews and protocols.
- Full-text Reviews examine the benefit of
methodological studies e.g. Does editorial
peer-review improve the quality of reports of
biomedical studies
- Health Technology Assessment Database
- (HTA)
-
- Contains information on healthcare technology
assessments, including details of ongoing
projects and completed publications from health
technology assessment organisations
- Plus information on the Collaboration and its
Review Groups.
12- THE COCHRANE METHODOLOGY REGISTER
(CMR) - Contains a bibliography of publications which
report on methods used in the conduct of
controlled trials. - It includes journal articles, books and
conference proceedings, these articles are taken
from the MEDLINE database and from hand searches.
