The Cochrane Library - Full Guide The Cochrane Library - Full Guide What is the Cochrane Library? The Cochrane Library is the most authoritative and up to date source of evidence based information and can help clinicians make decisions about appropriate and effective health care. It brings together in one place research which looks at the effectiveness of different health care treatments and interventions. Why is Cochrane information good quality? The Cochrane Database of Systematic Reviews provides an excellent source of good quality systematic reviews which are considered the gold standard of evidence based information. All literature is critically appraised, and only studies that meet certain quality targets is included. Cochrane contacts universities directly for unpublished trials – this information could be missed out in other databases. The information is unbiased as it is not sponsored by drug companies. The Cochrane Databases The Cochrane Library is made up of seven databases which include: Cochrane Database of Systematic Reviews (Cochrane Reviews) This is the Cochrane database that is best known. This database contains systematic reviews, mainly made up of randomized controlled trials, that evaluate the effectiveness of different types of healthcare interventions. These systematic reviews are intended to help health professionals make evidence- based decisions about the interventions used in health care. Database of Abstracts of Reviews of Effects (Other Reviews) Contains abstracts of non Cochrane systematic reviews, and provides a critical appraisal of them. Cochrane Central Register of Controlled Trials (Clinical Trials) Contains details of published articles from bibliographic databases. This includes the article citation, and usually the abstract too. There is some overlap in the information contained here with Medline and Embase. Cochrane Database of Methodology Reviews (Methods Reviews) A full text database of systematic reviews of empirical methodological studies that have been put together by Cochrane. Cochrane Methodology Register (Methods Studies) Contains bibliographic details of literature that reports on methods used when doing clinical trials. Anita Phul, BSMHFT Library Service, 0121 301 2059, [email protected] Last Updated April 2011 Health Technology Assessment Database Contains literature that helps to improve the quality and cost effectiveness of health care interventions. These studies measure the medical, social, ethical and economic aspects of these interventions. NHS Economic Evaluation Database (Economic Evaluations) Contains economic evaluations of health care interventions from around the world, to help make cost effective health care decisions. Cochrane Search Example Search Question: Is psychotherapy effective for panic disorder? Example of how to do a comprehensive search on Cochrane. (For easy searches, please use the Cochrane “Quick Guide.”) 1. Getting into the Cochrane Library The Cochrane library can be accessed from anywhere with Internet access. No password is required to search the Cochrane Library databases. Type www.thecochranelibrary.com into the address bar of your Internet browser to get into The Cochrane Library. 2. Typing in keywords Type in your first keyword in the box on the top right hand side of the screen. In this example it is panic. Choose to search in the Title, Abstract or Keywords field by using the dropdown list to the right. (This selection may already be selected). Then click on the Go button. Anita Phul, BSMHFT Library Service, 0121 301 2059, [email protected] Last Updated April 2011 3. Doing a MeSH search Next click on the MeSH Search link to do a MeSH search for this keyword as well. (This is like a subject heading where indexers have indexed all documents about a particular topic with a relevant MeSH tag). Type panic in the Mesh Search box and click on Thesaurus Select the appropriate Mesh descriptor by clicking on it. In this case, it is panic disorder The Mesh term that you selected will become highlighted in red. Click on the View Results button to proceed. Anita Phul, BSMHFT Library Service, 0121 301 2059, [email protected] Last Updated April 2011 Next, click on the Search History link at the top of the page Handy Tip! If search steps don’t seem to be appearing in your search history, click on the Refresh button at the top of your screen to make them appear. Search History Type #1 or #2 into the search bar to combine your panic searches together. Then click on the Go button. You should now have three searches in your search history. Repeat the above search steps for the psychotherapy search term. (Do a title, abstract, keywords search, and then a Mesh search for this keyword, then combine the psychotherapy search steps together with an OR). Anita Phul, BSMHFT Library Service, 0121 301 2059, [email protected] Last Updated April 2011 4. Combining keywords When you have combined your two psychotherapy searches together by typing in #4 or #5, you are now ready to combine the panic disorder results with the psychotherapy results to make sure each document retrieved contains both these subjects in it. To do this, type #3 and #6 into your search bar. Then click on the Go button. Anita Phul, BSMHFT Library Service, 0121 301 2059, [email protected] Last Updated April 2011 5. Viewing search results Then click on the #3 and #6 link in your search history (it is a link in itself) to view your search results. The database you are currently in will be highlighted in black bold font at the top of the screen. For example, the screen below is displaying the results in the Cochrane Reviews database. Click on other databases (listed horizontally) to view documents in them. If you click on the record link, you will be able to read the document. The R symbol by a document means that it is a full Cochrane review, and the lighter blue P symbol by a document means that it is just a protocol. Anita Phul, BSMHFT Library Service, 0121 301 2059, [email protected] Last Updated April 2011 Once you have clicked on the record link, you can click on the links on the left hand side to jump straight to certain sections such as objectives, discussion, or authors’ conclusions. Click on the PDF link in the left hand margin to view the entire document on continuous pages. For further information and interactive training on the Cochrane databases, please contact your local BSMHfT library. A regular programme of training courses is available, and dates can be viewed on the Trust Training Database on the Intranet. These courses are ‘hands on’ and provide an opportunity to improve literature searching skills in a supportive, interactive environment.

  • The Effective Health Care Research Consortium (EHCRC) Publication
    Consortium Publication Policy, 20 February 2013 The Effective Health Care Research Consortium (EHCRC) Publication policy The Effective Health Care Research Consortium (the Consortium) has extensive experience in medical publishing, research ethics, and principles of research integrity. Using this experience, and helped by a specialist in the field, we have drawn up this policy document to help promote capacity development in research integrity. 1 This policy applies to all supported Consortium activities. In addition, we encourage partners to use this to prompt their own departments and institutions to develop similar explicit policies. 1. Scope This policy relates to academic publications in peer-reviewed journals including systematic reviews published on The Cochrane Library. This includes authors working with the Cochrane Infectious Diseases Group (CIDG), all Consortium supported Cochrane authors, and all Consortium supported research publications. The policy applies to all outputs from the programme and associated grants (for example, self-published material, reports, newsletters, and blogs). 2. General principles Work supported by the Consortium will be published in a timely and responsible manner. All reports and publications will endeavour to present findings in a responsible, objective and accurate manner and without undue delays. Those who have made a significant contribution to the research will be recognised appropriately by authorship or acknowledgement. 3. Registration of systematic reviews and clinical trials All systematic reviews initiated by the consortium that are not registered as Cochrane Reviews will be prospectively registered on a suitable register (such as PROSPERO). We expect anyone receiving Consortium funds as support to their work (as money, or in kind, such as payment of travel) will, should they be involved in a clinical trial, ensure this trial is registered prospectively (i.e.

  • Cochrane Collaboration Conversation with Givewell
    Meeting between Cochrane Collaboration representatives and GiveWell at the U.S. Cochrane Center, May 8, 2012. From the Cochrane Collaboration: Kay Dickersin Director of the U.S. Cochrane Center and the Eyes and Vision Review Group, U.S. Satellite Lorne Becker Director of the Cochrane Collaboration Trading Company and Cochrane Innovations Jeremy Grimshaw Co-Chair, Cochrane Steering Group, Director of the Canadian Cochrane Center, and Coordinating Editor of the Cochrane Effective Practice and Organization of Care Roger Soll Coordinating Editor of the Neonatal Review Group and Member of the Executive Board of the Review Group Coordinating Editors Lisa Bero Director, U.S. Cochrane Center (San Francisco Branch) and Cochrane World Health Organization delegate George Rutherford Coordinating Editor, HIV/AIDS Review Group From GiveWell: Holden Karnofsky and Stephanie Wykstra These notes reflect answers that Cochrane representatives gave during our conversation. Cochrane Collaboration’s aims: • Cochrane Collaboration’s primary aim is to produce high quality systematic reviews of existing health-related research. The organization also trains researchers to do systematic reviews, develops better methods for analyzing and comparing studies in its systematic reviews and educates researchers in the use of these methods, and advocates for evidence-based decision- making within the World Health Organization (WHO), governments, professional associations, consumers and other groups. Structure of the organization: • The Cochrane Collaboration uses a multilevel level organizational and governance structure, comprising a group of “entities” that are organized around functions related to conducting and disseminating systematic reviews of the evidence. Each Cochrane organization (or “entity”) provides its own governance structure and is responsible for raising its own funding.

Low-level laser therapy (LLLT) was discovered enhancing tissue repair via increasing the blood microcirculation and cell proliferation in 1960s. In the last two decades, LLLT delivered to the cochlea has frequently been used to reduce the severity of tinnitus. However, whether LLLT effectively attenuates the severity of tinnitus remains controversial. We aimed to evaluate the efficacy of low-level laser therapy on adult patients with complaints of tinnitus. Design: Systematic review and meta-analysis with trial sequential analysis. Interventions: Low-level laser therapy (LLLT). Measurements: Tinnitus Handicap Inventory (THI) score; improvement rates of the visual analog scale (VAS), verbal rating scale (VRS) and numeric rating scale (NRS) scores.

  • Evidence-Based Medicine (EBM): What Long-Term Care Providers Need to Know
    Evidence-Based Medicine (EBM): What Long-Term Care Providers Need to Know Huai Y. Cheng, MD, MPH KEYWORDS Evidence-based medicine Long-term care facility Nursing homes EBM Evidence-based medicine (EBM) has been exponentially disseminated to every field of medicine over past 2 decades.1–7 EBM is now a part of postgraduate competency through practice-based learning.8 However, its potential use in the long-term care setting was only recently appreciated in the literature.1,9,10 EBM may play an important role in reforming nursing homes and improving quality care.1–5,9,10 The simple search term “EBM,” limited to English and human in Medline, generated 49,304 citations, which narrowed to only 173 when “nursing homes” was added, indi- cating that EBP is not rare and is being implemented in long-term care. It has been a great effort that each article in this special issue presents evidence-based recommen- dations to long-term care providers to guide their daily practice. In contrast to the evidence-based approach to individual geriatric conditions addressed in the other arti- cles in this issue, this article briefly introduces the basic concept of EBM; addresses some potential benefits, harms, and challenges of its practice in a long-term care setting; and promotes its appropriate use among providers of long-term care. For those who already know the EBM basics and are interested in become experts, several textbooks on EBM are recommended.11–13 Attending an EBM workshop, such as one run by McMaster University,14 could also be helpful.

  • The Cochrane Collaboration: a Valuable Knowledge Translation Resource
    TECHNICAL BRIEF NO. 29 2010 A Publication of the National Center for the Dissemination of Disability Research (NCDDR) Focus The Cochrane Collaboration: A Valuable Knowledge Translation Resource The Cochrane Collaboration has become the premier source worldwide of high-quality systematic reviews in health care. Cochrane’s importance has even been compared to that of the Human Genome Project (Naylor, 1995). The Cochrane Collaboration’s focus on health care applies in many ways to disability and rehabilitation, particularly in the health and function domain. The purpose of this FOCUS Technical Brief is to provide a brief overview of The Cochrane Collaboration and to highlight entities and resources of the Collaboration that can assist disability and rehabilitation researchers and knowledge users in their knowledge translation (KT) efforts.
