Cochrane Ear, Nose & Throat Disorders Group Newsletter May 2013


The 20th anniversary of the founding of The Cochrane Collaboration marked in 2013 The occasion of our 20th Anniversary is being celebrated throughout the year with a series of events, publications and videos. Many of you have been members of the Cochrane ENT Group and the wider Cochrane Collaboration for many years and we thank you for your contribution and support. We hope that you share our pride in our achievements. For those of you who are new to Cochrane, we would like to take this opportunity to tell you a little about our organisation:

Who we are and what we do The Cochrane Collaboration is a not-for-profit, global network of approximately The Cochrane Collaboration is named 28,000 dedicated people in 120 countries. We are all bound by a shared passion in honour of Archie Cochrane a British medical for helping patients, policy-makers and practitioners make informed healthcare (1909-1988), researcher who made a great decisions based on all the best research evidence available. The Collaboration contribution to the science of also has a small central team of 500 full- and part-time staff. Many of our epidemiology. Picture credit: Cardiff University contributors are world leaders in their field of medicine, health policy, research Library, Cochrane Archive, University Hospital Llandough methodology and consumer advocacy. These experts work together from all over the world and are situated in some of the world’s finest academic and medical institutions. The best scientific evidence on whether different drugs and procedures are safe and effective is scattered across different sources and journals, often in different languages. Practitioners and patients need a fast way to access the best evidence and use it to influence their decisions. They also need to know that the source of this evidence is trustworthy and kept up-to-date. The Cochrane Collaboration is a trusted organisation that gathers the best available scientific evidence, analyses what this collective evidence says about a particular drug or procedure, and shares the findings with practitioners, governments and the public. We use a powerful, systematic process to create Cochrane reviews. Our reviews are widely considered to be the gold standard of health evidence. The work of The Cochrane Collaboration touches on multiple aspects of health and health care. We produce Cochrane reviews across the widest possible range of healthcare topics. The Cochrane Library now includes more than 5400 individual reviews on a wide range of healthcare topics, with more than 2300 underway. These reviews are produced by 53 different Review Groups, of which the ENT Group is one, each focused on specific aspects of health.

What makes us unique and important The Cochrane Collaboration is a recognised leader in furthering the science of systematic reviews. Before Cochrane embarked on its work, systematic reviews were virtually unknown in health care. From its inception, The Cochrane Collaboration has involved innovative methodologists who developed many of the methods that have set the standard for systematic reviews today. These standards and methods are continuously being developed and improved. We are generating impact around the world. Fifty per cent of the world’s population has free one-click

access to full-text reviews (many low-income countries are granted free access to The Cochrane Library). From February 2013 all Cochrane reviews will be freely available via ‘open access’ 12 months after publication in The Cochrane Library. Abstracts and Plain Language Summaries of all Cochrane reviews are also available for free worldwide. Cochrane reviews are frequently used to set national and international healthcare policies and regularly appear in guidelines. Some of the guidelines citing ENT reviews in the last 12 months are listed here. The Cochrane Collaboration’s reputation for excellence has allowed us to forge close working ties with several of the world’s leading independent healthcare bodies, including the World Health Organization. We have been awarded a seat on the World Health Assembly, allowing the Collaboration to provide input on WHO health resolutions as a Non‐Governmental Organization in Official Relations with the WHO.

The principles & ethos of The Cochrane Collaboration We are dedicated, first and foremost, to advancing health care. We foster a culture of sharing, not competition. We encourage open and transparent communication and collaboration between all our contributors around the world. One of the main principles of The Cochrane Collaboration is minimising bias. We have a strict policy that prevents commercial sponsorship, in any form, from supporting the creation of any Cochrane review. We are not influenced by commercial or financial interests. Our independent status helps us maintain the quality of our output at all times. The Cochrane Collaboration is led by a Board of Trustees, known as the Steering Group, which is made up of elected members from around the world, drawn from the leadership of Cochrane groups. Expert scientists, researchers, health policy-makers, consumer advocates and patients give their time freely, and align themselves with our ethos, to produce Cochrane reviews. Our volunteer-driven model means those individuals who contribute to the Collaboration do so for the public good. This is far more sustainable than a remunerative model. In fact, the number of people working within Cochrane in 120 countries has increased by about 25 per cent every year for the last five years. People want to be a part of this effort. We aim to empower patients and healthcare consumers by providing the evidence they need to make informed decisions about their own health care and ensuring patient viewpoints are included in the Cochrane review production process. We publish our Plain Language Summaries and abstracts online, making them easy to search and available free of charge to the public in The Cochrane Library and through Cochrane Summaries.

How our stakeholders can contribute to the success of our mission We encourage people with different skills and backgrounds to contribute to The Cochrane Collaboration in a variety of ways. These might include: preparing new or updated systematic reviews, training people to conduct and use Cochrane reviews, developing methodology and acting as peer reviewers. We continually strive to reduce barriers to contributing and are committed to encouraging diversity. Health care is, ultimately, about patients and their families. That’s why we encourage patients throughout the world to share their perspectives and influence the direction and output of healthcare research through their involvement in the Cochrane Consumer Network. The Cochrane Collaboration has a broad collegial framework, not framed by traditional structures. As a part of the Collaboration, you have access to a large and varied medical, academic and scientific network. There is a generation of social and intellectual capital in The Cochrane Collaboration. It is a remarkable and generous organisation, whose spirit and ethos allows its international contributors to improve health and the place of evidence while building relationships with colleagues around the world.

21st Cochrane Colloquium Better Knowledge for Better Health (Un meilleur savoir pour une meilleure santé) The focus of this year’s Colloquium is on how evidence informs healthcare decisions at every level - from patient to practitioner, to institutional or government policy-maker. Plenary sessions will feature international experts addressing topics within this theme, from the perspectives of decision-makers, global health and equity and looking both back over the last 20 years of better knowledge for better health and forward to the next 20 years. In addition, there will be special sessions on specific topics, including: Wikipedia and transferring health information; Patients, evidence production and its use; Evidence for policy-makers; Systematic reviews and guideline development. The Colloquium will commence on Friday 20 September 2013 with the opening ceremony and first plenary session and end on Monday 23 September. In addition to an excellent scientific programme, there will also be a superb social programme with opportunities to network and meet new and existing colleagues from around the world. The Welcome Reception will take place on the evening of Thursday 19 September. Registration is now open. An early registration discount is available until 15 July 2013 and registration closes on 6 September 2013. Full details are at

Cochrane signs up to AllTrials initiative to campaign for registration and reporting of all clinical trials “Patients around the world are being harmed because clinical decisions on their health care are skewed by the absence of clinical trials data. For 20 years The Cochrane Collaboration has been working to give clinicians, researchers and patients the best possible evidence-based information to help them make informed decisions, and it is a scandal that we still do not have access to all trials data so that we can be confident in our conclusions. By taking this step, we hope to emphasize to Cochrane contributors worldwide that, through working together to maximize the impact of our collective voices, we can achieve as much in this area as in our work to produce Cochrane reviews.” Mark Wilson, CEO of The Cochrane Collaboration, announcing the new partnership

The AllTrials initiative (All Trials Registered | All Results Reported) was launched in January 2013 to campaign on the issue of unreported trial data. Full release of data is critical to allow clinicians and regulators to make informed decisions about treatments, yet hundreds of thousands of clinical trials have been conducted from which no or insufficient data have been made available. This is a major problem for clinicians, patients, policy-makers and healthcare researchers such as The Cochrane Collaboration. We depend on complete release of evidence about a treatment to fully assess its benefits and harms. Since its inception, the AllTrials initiative has gathered more than 50,000 signatures and has gained the support of hundreds of organisations and institutions working in research, patient advocacy and health care. The Cochrane Collaboration was one of the first organisations to offer support and in April 2013 formalised its involvement as a principal supporter and organiser of the AllTrials campaign. All Cochrane contributors are encouraged to read about the AllTrials campaign and to consider ways of bringing this campaign to the attention of their own local networks and institutions.

Publication & The Cochrane Library news New publishing contract for The Cochrane Library The Cochrane Collaboration has renewed and re-defined its partnership with John Wiley & Sons, Ltd., to publish The Cochrane Library from February 2013 for a further six years, to the end of 2018. Key features of the new agreement include:  Open access to Cochrane reviews after 12 months.  Enriched user experience of The Cochrane Library, including:  linking content in new and dynamic ways;  upgrading the ‘look and feel’ of the Library;  customising the website for different user groups or preferences and creating the technological flexibility to incorporate those platforms into other health systems;  moving from monthly publication of Cochrane reviews and protocols to a ‘publish when ready’;  upgrading the search functionality for advanced users; "This new agreement provides a huge  implementing a new classification framework for boost to The Cochrane Collaboration's Cochrane reviews to highlight whether a Cochrane work.

For full details of the new publishing arrangements see here.

Cochrane reviews to be ‘open access’ after 12 months Under the new publishing agreement with Wiley, new Cochrane reviews and Cochrane reviews with new citations, and protocols published from 1 February 2013 will become available on an open access basis 12 months after publication in the Cochrane Database of Systematic Reviews (green open access). Additionally, authors and funders have the option to fund individual articles, or groups of articles, to be open access immediately upon publication (gold open access). Authors from many low- and middleincome countries will be eligible to have their publication fees waived. More information about all aspects of the new access options is also available on this page. The Licence for Publication Form which authors sign when we publish their reviews and protocols has been amended to reflect the introduction of green open access. Authors now have the right to post a PDF of the final version of their protocol or review in an institutional repository or any repository mandated by the author’s funder, such as PubMed Central, 12 months after publication. It also clarifies the right to post the protocol or review as an electronic file on the author’s own website and/or the author’s institution’s intranet, using the PDF version available in the Cochrane Database of Systematic Reviews. These new terms are backdated to 1 February 2013.

Publication & The Cochrane Library news Faster publication of Cochrane reviews from June 2013 From Monday 3 June 2013 we will be moving from our current monthly publication schedule to ‘publish when ready’. This change means that we at the ENT Group editorial base will be able to publish new reviews, protocols and updates immediately. We will also have the flexibility to choose a publication date and time to fit in with other requirements or events (such as a press release). Without fixed deadlines, we will have more freedom to take the time needed to make sure all published work is as we and the authors want it to be. At the same time, once approved for publication authors will be able to enjoy seeing their work released with minimal delay. The ‘publish when ready’ model will bring real benefits to those who read and use Cochrane reviews, our authors and to the editorial team. Forms Release for publication will still depend upon all co-authors completing the necessary ‘License for publication’ and ‘Conflicts of interest’ forms online in Archie. To speed this process, make sure you activate your Archie account and respond promptly to the form request e-mails.

Update your review! All Cochrane review updates now receive a new MEDLINE citation Until 2012, updated Cochrane reviews republished in the Cochrane Database of Systematic Reviews (CDSR) only received a new citation in MEDLINE if the changes made were substantive (generally speaking, changes which resulted in a change to the review conclusions). This policy has now changed and all updated Cochrane reviews, whether the change is substantive or minor, receive a new citation. This change in policy has been implemented following discussions between the Cochrane Editorial Unit and the National Library of Medicine (NLM). It ensures that abstracts displayed in CDSR and in PubMed are consistent. Updated reviews will also now be correctly placed when search results are sorted in PubMed by date and it will be much clearer to users that a Cochrane review has been updated. It will also help to make the last updated date much more visible in CDSR. This is good news for authors, as it means that all the hard work that goes into an update will be always be recognised with a new citation, whether the review has changed significantly or not.

Impact factors for 2011 In June 2012, the impact factors of all journals indexed in the ISI Journal Citation Report were published. The 2011 impact factor for the Cochrane Database of Systematic Reviews (The Cochrane Library) is 5.912. The individualised 2011 impact factor for the Cochrane ENT Group is 3.667 (24 publications cited 88 times). In other words, a review published by the Ear, Nose and Throat Disorders Group in 2009 or 2010 was cited, on average, 3.667 times in 2011. This made us the top-ranking ENT journal. Impact factors for 2012 will be released in June 2013 and we will inform ENT Group members via our e-newsletter.

Funded ENT projects Cochrane/National Institute for Health Research (NIHR) (UK) Incentive Award funding for a systematic review of ‘Antibiotics for otitis media with effusion in children’ (van Zon et al) enabled completion of this important review which was published in Issue 9, 2012 of The Cochrane Library. Our NHS-Cochrane Engagement Award project ‘Helping commissioners, managers and GPs make more use of Cochrane reviews: an investigation focused on ENT disorders’, undertaken in conjunction with the Department of Primary Care at the University of Oxford, was successfully completed. Recommended changes to our reviews that were an outcome of this project have already been implemented, with the development of linked video Picture: meeting of the adenoidectomy IPD metacontent demonstrating the Epley manoeuvre and Dill-Hallpike analysis project team and triallists, Balliol College, test.

Could you help us with occasional translation? When our authors are working on their systematic reviews they frequently identify trials published in languages other than English. As the range of international databases we search on behalf of authors has expanded over the years, the number of non-English language papers encountered has steadily increased. These papers need to be assessed for eligibility for potential inclusion in our reviews and, if they meet the necessary criteria, have data and other information extracted. For this we need a pool of volunteers with a wide range of languages that we can call on from time to time. We are enormously grateful to the Cochrane authors who already regularly help us out with occasional translation; from a basic quick check for eligibility to full data extraction. We always need more translators, however. If you have a language and would be able to offer occasional help please get in touch with Jenny Bellorini, Managing Editor (

James Lind Alliance: work in ENT Top 10 tinnitus research questions In September 2012, the James Lind Alliance (JLA) Tinnitus Priority Setting Partnership (PSP) published the top 10 research uncertainties for tinnitus agreed by patients and clinicians:

 What management strategies are more effective than a usual model of audiological care in improving outcomes for people with tinnitus?

 Is cognitive behaviour therapy (CBT), delivered by audiology professionals, effective        

for people with tinnitus? Here comparisons might be with usual audiological care or CBT delivered by a psychologist. What management strategies are more effective for improving tinnitus-related insomnia than a usual model of care? Do any of the various available complementary therapies provide improved outcome for people with tinnitus compared with a usual model of care? What type of digital hearing aid or amplification strategy provides the most effective tinnitus relief? What is the optimal set of guidelines for assessing children with tinnitus? How can tinnitus be effectively managed in people who are deaf or who have a profound hearing loss? Are there different types of tinnitus and can they be explained by different mechanisms in the ear or brain? What is the link between tinnitus and hyperacusis (over-sensitivity to sounds)? Which medications have proven to be effective in tinnitus management compared with placebo?

One of these topics is already being taken forward as a Cochrane review: ‘Amplification with hearing aids for patients with tinnitus and co-existing hearing loss’ (Protocol).

New Rhinology Editor In January 2013 we welcomed a new editor to the ENT Group: Dr Richard Harvey agreed to join our editorial panel to assist with rhinological topics. Dr Harvey is Program Head and Conjoint Associate Professor in Rhinology & Skull Base Surgery at the University of New South Wales & St Vincent's Hospitals, and Clinical Associate Professor and Macquarie University, Australia. He has authored or co-authored four Cochrane rhinology reviews and has been a peer referee for our group. We are delighted that Dr Harvey has become further involved with the Group in an editorial capacity.

Presentations - video and slidecast presentations on:  core topics in the preparation of intervention reviews;  specialised and advanced topics for intervention reviews;  reviews of diagnostic test accuracy. Other resources - essential documents and useful links.

Evidently Cochrane Sharing the latest Cochrane reviews The UK Cochrane Centre has launched a new ‘Evidently Cochrane’ blog to disseminate the results of Cochrane reviews that are of interest to the UK National Health Service (NHS). In January 2013 the review on 'Topical steroids for nasal polyps' was featured. Read the blog here.

Globally, a growing number of students are interested in becoming involved with evidence-based health care. If you are a medical or nursing student, or still at school and thinking about working in health care, you may be interested in a new website which is being put together with the support of the UK Cochrane Centre. ‘Students 4 Best Evidence’ aims to pull together evidence-based health care resources for newcomers in one interactive space, providing all the information you need plus the opportunity to meet other likeminded students. The website will be officially launched shortly; bookmark it now!

Managing expectations: What does The Cochrane Collaboration expect of authors, and what can authors expect of The Cochrane Collaboration? Producing a Cochrane review and keeping it up to date requires significant commitment and author teams also need to have diverse competencies and skills. At the same time, authors should be able to expect a certain level of support from the staff at their editorial base (i.e. the ENT Group) and their local Cochrane Centre. The Cochrane Collaboration is committed to inclusivity and encourages wide participation in its activities, however the level of support editorial teams and centres are able to provide to authors is inevitably limited, particularly as the number of Cochrane reviews being produced continues to increase rapidly. Cochrane reviews also need to meet very high standards of quality. With this in mind, The Cochrane Collaboration Steering Group has issued a new policy document, which sets out in general terms the minimum expertise and skills that any group of authors will need to bring to their review project, as well as the support that authors should be able to expect from their editorial team. The document sets out these broad expectations for all parties and forms the basis of a ‘contract’ between authors and editorial teams and centres. New authors for the Cochrane ENT Group are sent a link to the document at the point that their new title is registered. Existing authors may also be interested to read it: managing expectations document.
