Featured Review: Combination fixed-dose beta agonist and steroid inhaler as required for adults or children with mild asthma
Cochrane Airways works with authors (typically clinicians and researchers) to produce systematic reviews on chronic obstructive pulmonary disease (COPD), bronchiectasis and other lung diseases, and asthma.
We asked Dr Timothy Hinks, one of the Cochrane Review authors, about the findings of this recent review.
For those with mild asthma, there are different types of inhaler. What’s the difference?
There are two main types of inhaled medications for asthma. ‘Relievers’ treat just the symptoms by relaxing the constricted airways, these medicines are ‘beta-agonists’, some of which are fast-acting (FABA) and provide symptom relief within 5-10 minutes. ‘Preventers’ are inhaled corticosteroids, which treat the underlying inflammation causing asthma. Inhaled steroids are very effective in reducing severe attacks of asthma and asthma deaths, but they need to be taken for several days at a time before people begin to feel the effects. Both medications are important and helpful. These different types of medicines were originally given in two separate inhaler devices and someone with asthma needed to use two different inhalers. This caused a problem that many people depended too much on the reliever inhalers because they provide rapidly relief of symptoms, but this can lead some people not to take as much of the preventer inhalers as needed to effectively treat the underlying problem, increasing the risk of severe asthma attacks, and hospitalisation or death.
In recent years inhalers have become available which contain both the beta-agonist and the inhaled corticosteroids in a single device. Combination inhalers have proved very effective in moderate and severe asthma, but till now it was not known whether they might be the best way to treat people with mild asthma – who make up the majority of people who suffer from asthma.
Tell us more about this review; why did you think it was important to do it?
We looked at the use of combination inhalers in mild asthma using a strategy where the inhaler is only used when people experience symptoms. We compared this with two current approaches to treatment: just using a reliever when needed, or using a reliever when needed on top of regular daily use of a preventer. We chose to do this study now because several recent large clinical trials have reported in the last 3 years which directly addressed this question. Consequently several national and international guidelines are being revised to reflect the findings of the study. We aimed to provide an objective, global review of the available evidence to inform decision makers, clinicians and people with asthma.
What did the review find?
We found that combination inhalers used as-needed reduced severe exacerbations requiring tablet steroids and rates of emergency admission to hospital with asthma symptoms when compared with reliever-only treatment.
Combination inhalers used as-needed were as effective as daily preventative steroid inhalers. People using combination inhalers as-required had lower rates of hospital admission and overall used a lower total inhaled steroid dose.
What’s the core message for clinicians and patients?
These findings suggest that as-required use of combination inhalers is an effective and safe approach to the treatment of mild asthma, and could reduce the number of severe asthma attacks. This is important as asthma is a major cause of time off work, economic costs, and chronic ill health and it remains a largely preventable cause of death for 400,000 people per year globally. This approach also simplifies treatment regimes and could reduce contradictory or ambiguous messages to people with asthma. It would support adoption of this strategy in current guidelines. However cost frequently limits the availability of these inhalers in many low and middle income countries, who rely heavily on reliever therapies or tablet steroids instead. We need further pragmatic studies and healthcare cost assessments in such countries to support equitable access to affordable quality-assured asthma medicines.
Featured Review: Paying for performance to improve the delivery of healthcare services in low- and middle-income countries
A recently published review from Cochrane Effective Practice and Organisation of Care (EPOC) Group looks at the effects of ‘pay for performance’ strategies on the delivery of healthcare services in low- and middle-income countries.
Karin Diaconu, first author of this review, notes, "There is growing interest in paying for performance as a strategy for aligning the work of health providers and healthcare organizations with public health goals. The volume of schemes implementing paying for performance has increased over the last decade and so has the number of studies on the effectiveness of these strategies in low- and middle-income countries.
This review brings this evidence together and asks how successful schemes are in improving health care and health. The review notes that paying for performance may have some positive effects: it may lead to increased uptake of some health services, better quality of care, and improve the availability of resources as well as improving autonomy of involved healthcare organisations."
Pay for performance strategies may have both positive and negative effects on the health services they target. These strategies may also have positive effects on other health services that are not directly targeted and may have no unintended negative effects on these services. However, most of this evidence is of low certainty and we need more, well-conducted studies on this topic.
What is ‘pay for performance’?
In a 'pay for performance' approach, people are given money or other rewards if they carry out a particular task or meet a particular target. This strategy is usually directed at health workers or healthcare organizations. The health workers or healthcare organizations are rewarded if they offer particular services or deliver care that is of a certain quality, or if their patients use particular services and achieve better health as a result.
Planners use these strategies to target specific health problems and services that need improvement. But it is also possible that pay for performance strategies have positive or negative effects, including on other services that are not specifically targeted. For instance, these strategies could lead health workers to improve the quality of the other services they deliver. But it could also lead them to avoid services that do not give extra payment. To find out more, the review authors assessed the effects of paying for performance on both targeted and untargeted services. This included looking for any unintended effects of the strategies.
What are the main results of the review?
The review included 59 relevant studies. Most were from sub-Saharan Africa and Asia. Most of the pay for performance schemes in the studies were funded by national Ministries of Health, also with support of the World Bank.
Forty-nine studies compared health facilities that used pay for performance strategies to health facilities who were doing business as usual. Seventeen studies compared health facilities that used pay for performance strategies to facilities that used other strategies. In most of these studies, health facilities using pay for performance strategies were compared to facilities who were given the same amount of funds but without a pay for performance element.
The effects of paying for performance compared to business as usual
For health services that are specifically targeted, pay for performance strategies:
- may improve health outcomes, may improve service quality and probably increase the availability of health workers, medicines and well-functioning infrastructure and equipment
- but may have both positive and negative effects on the delivery and use of health services
For health services that are untargeted, pay for performance strategies:
- probably improve some health outcomes
- may improve the delivery, use and quality of some health services but may make little or no difference to others
- may have few or no unintended effects
- we don’t know what the effects of pay for performance are on the availability of medicines and other resources because the evidence was of very low certainty
The effects of paying for performance compared to other strategies
For health outcomes and services that are specifically targeted, pay for performance strategies:
- may improve service quality
- may make little or no difference to health outcomes
- may have mixed effects on the delivery and use of health services and on the availability of equipment and medicines, including both positive and negative effects
For health outcomes and services that are untargeted, pay for performance strategies:
- may make little or no difference to health outcomes and to the delivery and use of health services
- we don’t know what the effects of pay for performance are on service quality, on the availability of resources, and on unintended effects because the evidence was missing or of very low certainty

Antidepressants are widely used for depression and anxiety. Guidelines recommend that an antidepressant should be continued for at least six months after people start to feel better, and for at least two years if they have had two or more periods of depression. Many people take antidepressants for much longer. Ellen Van Leeuwen and Mark Horowitz, authors of a recently published Cochrane review on approaches for discontinuing antidepressant use, answer some questions about the findings of the review.
Tell us about this Cochrane Review, why did you think it was important to do it?
Ellen: The rise in long-term antidepressant use is a major concern. For example, in the UK, nearly half of people using antidepressant (8% of the total population, approximately 3.7 million people) have been taking them for more than two years. Antidepressants that, despite initially being appropriate, are not discontinued after the recommended duration can lead to unnecessary harm and costs.
Mark: Antidepressants can put people at risk of adverse events such as sleep disturbance, weight gain, sexual dysfunction and gastrointestinal bleeding, as well as feeling emotionally numb and what they described as feeling “addicted,” because they cannot easily stop the medication. This is because people’s brains physically adapt to antidepressants after long-term use (called physical dependence). They may also impair patients’ autonomy to deal with problems in their life without medication. Guidelines recommend that antidepressants should be taken up to 6 to 12 months after improvement and 2 years after improvement in people at risk for relapse.
Ellen: As a GP I see many patients struggling with coming off antidepressants that they have been taking long-term. However, I was surprised that there wasn’t a Cochrane review on discontinuing long-term antidepressants, so I started this review. We included all studies comparing approaches for discontinuation with continuation of antidepressants (or usual care) for people who are prescribed antidepressants for depression or anxiety for at least six months.
What can people learn about discontinuation from antidepressants from this evidence?
Ellen: Honestly, the evidence in this area is very problematic. It is not possible to make any firm conclusions about the effects and safety of the approaches for discontinuation studied to date. There were only a few studies with a focus on successful antidepressant discontinuation rate.
The main problem is that studies did not distinguish between symptoms of relapse of depression and symptoms of withdrawal after discontinuation.
Mark: Yes, withdrawal symptoms can include insomnia, low mood, anxiety, changes to appetite, and these symptoms will be recorded on the depression scales used to detect relapse, so they might inflate the rate of relapse recorded in groups that stop antidepressants.
Additionally, most tapering regimes were limited to four weeks or less, in contrast to NICE guidelines recommending tapering over four weeks or more. In fact, there is now increasing recognition that antidepressants might need to be tapered over months or longer than a year to very low doses for long-term users.
Ellen: For me, it was disappointing that the large group of people taking antidepressants in the community (i.e. those with only one or no prior episode of depression) have been under-researched. Most published studies focus on people with recurrent depression. Another finding was that we found very low certainty evidence that high intensity psychotherapy such as mindfulness based cognitive therapy (MB-CT) and cognitive behavioural therapy (CBT) may support people to come off antidepressants. But none of the studies included more scalable and accessible psychological approaches such as online support.
And what can people learn about continuation of long-term antidepressant use?
Ellen: Based on the limitations we have mentioned, we cannot make any conclusion about this, as we were not confident in the evidence we found. We certainly need more de-prescribing studies investigating the harms and the benefits of discontinuation before we can make any conclusion.
Mark: Yes, it is very difficult to interpret existing studies that suggest continuation of antidepressants because they are based on discontinuation studies in which half of the patients are stopped – often abruptly or in a few days – compared to a group that continues their antidepressants. This means we can’t be sure whether the group who stopped got worse because of withdrawal symptoms or genuine relapse. To provide clearer evidence on this, future studies should distinguish carefully between relapse and withdrawal symptoms and follow emerging guidance to use taper schemes of many weeks or months (or longer for long-term users) down to very low doses before stopping. Such studies would give us a clearer idea of the ability of antidepressants to prevent relapse.
Ellen: Additionally, there is an urgent need to include wider representation of patient populations. For example, those people with one or no prior episodes of depression, those with anxiety disorders, and older people including those who take multiple medications (polypharmacy) and those who are frail. Most antidepressants are prescribed by GPs. This review reinforces the call for more research in the primary care setting, particularly for people with low risk of relapse and those for whom there is uncertainty about the benefit of antidepressant treatment.
What is the core message for clinician’s and patients?
Ellen: Overall there remain many uncertainties. However, this review aids clinicians in openly discussing with their patient and with family/carers (as appropriate) the potential benefits and harms of continuing or discontinuing antidepressants including withdrawal.
Mark: Doctors and patients should be aware that withdrawal symptoms from antidepressants are common and can be mistaken for relapse of the underlying condition. Although evidence found in this review is sparse, experiencing withdrawal symptoms is not a sign that the patient needs the antidepressant, but rather a sign that they might need to taper more gradually and down to lower doses before stopping.
What will happen next? Are you planning an update or any subsequent reviews on a linked topic?
Ellen: Celebrating with my team that we made it! No, I am currently working on a PhD of which the review is part of it which I want to defend in 2021. However, I’m continuing further research in the field of long-term antidepressants. One of the recommendations of our review is a further review comparing different discontinuation strategies.
Mark: At the moment there are a few studies happening around the world looking at discontinuing antidepressants, such as the REDUCE trial in the UK, some including somewhat slower tapers than the studies found in this review, going down to lower doses, and so an update to this review may be necessary in the future.

Wednesday 7 April marks World Health Day, a day organised by the World Health Organization (WHO) to highlight a particular global health issue. This year, it aims to spotlight health equity.
Health equity is the absence of avoidable and unfair differences in health. The COVID-19 pandemic and its uneven impacts worldwide has brought attention to long-standing inequities in living and working conditions which affect people’s health outcomes.
This World Health Day, WHO is calling on leaders to address these inequities, to monitor them, and to ensure people have access to quality health care.
Cochrane is committed to promoting the consideration of health equity in evidence synthesis and has been working on this in several ways.
Health equity in the Cochrane Handbook
The Cochrane Handbook for Systematic Reviews of Interventions has a full chapter dedicated to incorporating health equity in evidence synthesis.
Health equity in methods
Equity has its own standard in the Methodological Expectations of Cochrane Intervention Reviews (MECIR), the overarching standards which guide the conduct and reporting of Cochrane Intervention Reviews. The Campbell and Cochrane Equity Methods Group is also developing an equity checklist.
Cochrane Interactive Learning health equity module
There is a module of the Cochrane Interactive Learning course on health equity in systematic reviews. In it, users can learn about health equity and how and when health equity can be incorporated in all steps of the systematic review process. The module also addresses how health equity should be considered in planning aspects of knowledge translation.
Cochrane Review Group Networks’ health equity priority setting
Cochrane Review Group Networks are currently piloting an approach to incorporating health equity considerations in priority setting for the update of reviews. Eve Tomlinson, Network Support Fellow for the Cochrane Cancer Network, presented an update on this project at last week’s monthly Join the Conversation webinar. Watch the recording below.
Vaccine equity declaration
In March 2021, Cochrane also signed WHO’s Vaccine Equity Declaration, which calls for a more equitable distribution of vaccines for COVID-19.
Cochrane community contributes to update to the PRISMA statement. PRISMA is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses. PRISMA primarily focuses on the reporting of reviews evaluating the effects of interventions, but can also be used as a basis for reporting systematic reviews with objectives other than evaluating interventions (e.g. evaluating aetiology, prevalence, diagnosis or prognosis).
A dedicated global team of methodologists, search specialists, biostatisticians and systematic reviewers have spent the last few years diligently updating PRISMA - the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. First published in 2009, PRISMA was designed to help systematic reviewers transparently report why the review was done, what the authors did, and what they found.
While this may sound simple, it is anything but. Systematic reviews are complex, using an array of methods from the identification of studies through to the synthesis of results, and careful reporting is required so that users of the review (such as guideline developers, policy makers, healthcare providers and patients) are able to understand what was done and how the findings might apply to them.
The updated open-access PRISMA statement is available online and published in no less than five leading journals - including BMJ, PLOS Medicine, Journal of Clinical Epidemiology, Systematic Reviews and International Journal of Surgery. It represents a major global collaborative effort which was sustained throughout the many challenging months dominated by COVID-19 throughout 2020. The project had strong representation from Monash University's School of Public Health and Preventive Medicine, with co-leads Matthew Page and Joanne McKenzie (and David Moher, Ottawa Hospital Research Institute) and contributors Sue Brennan and Steve McDonald. This representation reflects the calibre of systematic review expertise within the School - with specialisation in methods for bias, statistics, certainty of the evidence (GRADE) and searching.
PRISMA workshop participants, Cochrane Colloquium, Edinburgh 2018
‘This was such a rewarding experience thanks to the enthusiastic input, detailed deliberations and expert contributions from both our local team and fellow researchers around the world,’ lead author Matthew Page explains. ‘The updating process involved lengthy consultation and a comprehensive survey of systematic reviewers, journal editors and methodologists with experience with and interest in the use of the previous iterations of PRISMA.’
‘We obtained a lot of valuable feedback via our initial survey. In addition to answers to more straightforward multiple choice questions, we also collated over 100 pages worth of collective free text comments from respondents who felt really passionately about particular reporting elements, and specified what they thought should or shouldn’t be included in the updated guideline. We had this wealth of feedback to draw on and discuss at our two day workshop at the Cochrane Colloquium in Edinburgh back in 2018, which was fantastic. A healthy degree of consensus emerged from that, followed by much drafting, redrafting and careful considerations around the clarity of language used to update existing and outline new recommendations. This was followed up by piloting with authors to get their feedback and incorporate a final round of changes.’
Joanne McKenzie played a critical role throughout this process, co-facilitating the development meeting and processing the meeting notes, developing the updated guideline structure and overseeing the inclusion of guidance on new statistical developments that have been introduced in the decade since the original PRISMA statement was released.
‘We know systematic reviews are essential for healthcare providers, policy makers, and other decision makers, who would otherwise be confronted by an overwhelming amount of research to guide their decisions,’ Joanne says. ‘We really wanted to make this a practical, accessible and contemporary checklist both for systematic reviewers and for the many different users who depend on them. As such, we included detailed information about why reporting of each item is recommended along with plenty of examples from published reviews.’
‘We’re hopeful that these kinds of changes and additions to PRISMA 2020 will encourage greater uptake of the guideline and lead to more transparent, complete and accurate reporting of systematic reviews around the globe. There are plenty of positives in that for everyone.’
In a study Matthew Page and colleagues conducted on Reporting Characteristics of Systematic Reviews in PLOS Medicine back in 2016, around 29% of authors explicitly reported that they used the PRISMA Statement to guide either the conduct or reporting of their review, and all those who worked on this update are hopeful this number will continue to rise.
‘Looking ahead, we’ll continue to work together to plan and design interventions and software to help with future implementation,’ Joanne concludes. ‘We’re keen to evaluate both the use and usability of PRISMA 2020 in the months and years to come, so while we’re excited about the launch today it’s definitely part of a bigger picture plan to support and encourage more accurate and complete reporting of systematic reviews now and into the future.’
In March 2020, Cochrane Australia convened the National COVID-19 Clinical Evidence Taskforce - bringing together leading health researchers, experts and organisations from across the country.
Since then, over 240 members have worked around the clock to deliver living clinical guidelines and flowcharts for frontline health workers. The guidelines are updated and published online every week, they feature 124 guideline recommendations and have reached more than 180,000 users worldwide.
To learn more about the work of Cochrane Australia and how the Taskforce is continuing to evolve, click here to read a short case story.
Cochrane Austria, together with TranspariMED and Transparency International Austria, has recently published a report on clinical trial transparency in Austria, which provides an update on figures released one year ago.
The report uses data from the EU Trials Tracker to summarise the clinical drug trial reporting rates of the 14 largest sponsors in Austria. Under EU rules, clinical trial sponsors must post summary results to the EU Clinical Trials Register within one year of a study ending, or six months for paediatric trials.
According to the new report, results have now been published for 37% of due clinical trials, compared to just 18%, as cited in 2020.
While this is impressive progress – with some institutions making significant efforts to publish their backlog of results – there is still more work to be done. 233 completed and overdue trials are still awaiting results on the EU registry, and half of the sponsors have made no progress at all.
Barbara Nussbaumer-Streit, co-director of Cochrane Austria, said: “The trend towards better reporting is welcome. However, we should not forget that two thirds of trial results are still missing. This can lead to delays in the development of new and effective therapies, and thereby harms patients.”
Gerald Gartlehner, co-director of Cochrane Austria, said: "Missing clinical trial results can lead to patients receiving ineffective therapies because doctors lack important information."
Cochrane supports clinical trial transparency. We rely on the availability of trial results to produce high quality and relevant systematic reviews. When trial results are left unpublished, it is impossible to make truly evidence-informed decisions about healthcare and people can be put at risk.

The global Cochrane community are participating in a virtual walk and raising money for the annual Anne Anderson Award, which is given to a Cochrane member who has contributed meaningfully to the promotion of women as leaders and contributors to the organization. To mark this occasion, we have added limited editions designs to the Cochrane store, with sales going to the Anne Anderson Award. We caught up with the artist, Heather Tubwon, to learn more about her and new designs.
Hi Heather! Our Cochrane Community always finds it interesting to learn the backstory to things and learn more about people. Could you tell us a bit more about yourself?
Sure! I'm from the Midwest in the United States. I have a Bachelor of Fine Arts degree in Illustration from the Minneapolis College of Art and Design. I have a background in Graphic Design, Illustration, and Textile/Surface Design. Some of my favorite jobs have included creating artwork for toys, children’s clothes, and stationery products - and now for Cochrane!
Was art something you always were interested in?
Yes - When I was around 10, my classmates noticed some of my drawings and told me I was really good at it. That’s when I first considered art as a career. However, life had a lot of twists and turns for me, and I ended up working in the airline industry. One of my tasks in that role was writing, creating diagrams, and laying out an FAA approved manual to teach Flight Operations personnel new software. I really enjoyed this work, and thought I might enjoy being a Graphic Designer professionally. After taking some design classes in art school, I realized my real passion was illustration.
These designs were a bit different for us. They are centered around our Cochrane Community event, the Anne Anderson Walk. While we knew we wanted to incorporate our brand colours, we were looking for something playful. How would you describe your style?
I would describe my style as colorful, whimsical, and fun. I feel like I create my best work when I’m having fun, and I hope this joy comes across in my work. If I can make someone smile through my work, then I feel like I have accomplished my goal.
We launched the Anne Anderson Walk on International Woman's Day and are highlighting all the virtual walk pictures on a global map. Diversity is a core value to the Cochrane Community and one of our strengths too - so we really wanted celebrate that. Why do you think showing diversity is important in visual arts?
I think that showing diversity is important in visual arts. I am multiracial myself - my primarily ethnically is Ashkenazi Jewish and Black. There have been many times where I was not able to see other people that looked like me in media, especially as a child. Growing up, my local library only had two books showing biracial or multiracial families. This made me feel othered, or like I was different from everyone else. That’s why I always strive to show diversity in my own work. Cochrane shows diversity not only in it's member make-up but also in it's methods and the contributions people make - I created the design to represent that.
Anne Anderson is a beloved person in the Cochrane Community. Can you tell us a bit about working on that artwork?
After reading about Anne Anderson, I was impressed with all that she was able to accomplish in her short life. She seemed like a very ambitious and driven woman, someone who was a role model for many. I was honored to be asked to create a portrait of her. In creating her portrait, I wanted to be respectful and honor her legacy, while at the same time creating a work that was playful and engaging.

Latest episode of the Dementia Researcher podcast chats about the work of Cochrane, how we support evidence-informed decision making in healthcare, our work on undertaking systematic reviews, and how you could become involved.
The Cochrane Dementia and Cognitive Improvement Group create reviews and methods guidance on all aspects of dementia, delirium and other cognitive disorders. Recent outputs have included a focus on diagnosis of dementia, which have been curated in to a Cochrane Library Special Collection, and reviews on prognosis and complex interventions.
The group Coordinating Editors are Dr Jenny McCleery and Dr Terry Quinn and they recently spoke with Dr Anna Volkmer and Adam Smith on the Dementia Researcher podcast. This biweekly podcast bring together panels of early career researchers and other dementia experts to discuss their research and career topics to support other early career researchers. The podcast covers research investigating Alzheimer's and other dementias, exploring prevention, diagnosis, treatments, care and how they're working to better understand the disease and the brain. For this session of the podcast they chatted about the work of Cochrane, how we support evidence-informed decision making in healthcare, our work on undertaking systematic reviews, and how you could become involved.
Terry (@DrTerryQuinn) is Senior Lecturer and Honorary Consultant in University of Glasgow. In addition to his Cochrane role, he works with the NIHR Complex Reviews Support Unit assisting author teams with evidence synthesis methods. Terry is passionate about increasing research capacity and supporting early career researchers and he hopes that the podcast will inspire enthusiastic researchers to get involved with Cochrane.
Jenny is a Consultant Psychiatrist in Oxford Health NHS Foundation Trust. Her work has involved older adults with dementia and their families for 25 years and her enthusiasm for Cochrane is driven by a wish to help provide accurate and accessible answers to the clinical questions important to her patients and colleagues.

Lund University working paper illustrates how to integrate Cochrane Interactive Learning to deliver relevant evidence-based medicine learning objectives
In the Medical Degree Program at Lund University, Sweden, a new Scientific Scholarship theme has been implemented, including evidence-based medicine (EBM), as the application of scientific scholarship in EBM is a core aspect of medical education. Throughout the program, scientific scholarship and EBM are supported by multifaceted learning activities and structured assessment, ensuring that students work continuously and iteratively with these concepts. The theme also makes use of e-learning for written assignments and of Cochrane Interactive Learning modules together with locally developed e-lectures.
Lead author, Maria Björklund, Librarian at the Faculty of Medicine, reported “the Cochrane Interactive Learning modules cover the process of how to conduct a systematic review, from formulating a question to finding, assessing and summarising evidence from studies. Each module contains videos, quizzes and exercises and an assessment that generates a certificate. Students upload their certificates to the university’s learning management system as part of the formal course assessment. The modules’ contents are of high quality, the level is challenging and requires students to be engaged. The assessment tasks and modules can be revisited, which gives opportunity for repetition. The methodology of conducting a systematic review contains many elements that are necessary to master also for other evidence-based work relevant to students in their role as future physicians, such as clinical guideline development. Therefore, the Cochrane Interactive Learning modules were considered highly relevant to integrate in the Scientific Scholarship theme.”
She concluded, “our implementation of the Cochrane Interactive Learning modules where they match the learning objectives is successful, in line with previous findings. Together with locally developed e-lectures and specialized library support students get additional context and examples. Collaboration with an evidence expert organization, such as Cochrane, give students authentic and international context together with an understanding of the importance of systematic reviews in EBM. This has led to a significant increase in the number of students performing a systematic review as their master thesis.”
Tips from Lund University
- To help embedding the Cochrane interactive Learning modules in courses it’s good if the learning outcomes of the course match the Cochrane module.
- It will also help if you plan to use the Cochrane modules as part of the overall course assessment.
- If needed, the modules can be studied and used over several semesters.
- If students are new to systematic reviews, it’s good to give them context, perhaps with other locally developed learning activities explaining the methodology of systematic reviews.
- Invite people to collaborate in using Cochrane Interactive Learning - librarians, teachers, clinicians - to help students get many examples and situations where the Cochrane modules can be used.
Chris Watts, Cochrane’s Learning Manager added “It’s fantastic to see our Cochrane Interactive Learning modules used in this way. We have designed the suite of modules so that, as well as being used by individuals as standalone, self-directed learning, they can also be adopted by trainers to use as part of blended learning approaches. The modular design and clear learning outcomes for the modules helps trainers to select and integrate Cochrane Interactive Learning into their learning programmes. The work at Lund is an excellent example of that, and we’re keen to encourage others to do the same or share their experiences of doing so with us.”
