In 2020, Cochrane’s editorial response to COVID-19 pandemic brought together collaborations across our global organization to publish reviews addressing stakeholder needs as they emerged. Large, highly organized review teams worked together to produce evidence addressing priorities in treatment, prevention, and diagnostics. In 2021, Cochrane continues to produce new and updated reviews in response to the pandemic.
In this interview with Deputy Editor in Chief Toby Lasserson and Executive Editor of Cochrane's Central Editorial Service Helen Wakeford, we ask them about Cochrane’s editorial approach to COVID-19 in 2021. The interview supports their paper, which sets out how Cochrane will respond to COVID-19 going forward and the priorities which inform this response.
What have you set out to explain in this paper?
Helen: "The scope of reviews that Cochrane could potentially publish on COVID-19 is enormous. In addition, most review questions have a rapidly evolving evidence base that demands frequent updating of the review in order for it to remain useful to readers. So we needed to prioritise key topics on which to focus our resources. This paper sets out those priorities, and the rationale for why we have identified them as such. In 2021 and beyond, we will consider future submissions against these priorities. We will also be able to identify evidence synthesis gaps within our priority areas and actively commission reviews.
We are aware that the COVID-19 pandemic is a rapidly evolving situation and we want to retain flexibility to respond to emerging priorities. In the report, we have explained that will stay tuned into organisations such as COVID-END who ‘horizon scan’ for emerging areas of need. We will also track the production of other high quality evidence syntheses to make sure that we are avoiding research waste."
What was 2020 like in terms of pace and coverage?
Helen: "2020 – at least, from March onwards - was extremely fast-paced! Authors from Cochrane Centres, CRGs and those who were new to Cochrane, worked around the clock to address urgent evidence synthesis questions. We considered producing preprints of these reviews, but instead developed an ultra-rapid editorial process of between 7-21 days in order to retain both speed and editorial rigour, and stay true to Cochrane’s reputation for ‘trusted evidence’. This meant close collaboration between the Central Editorial Service team and many colleagues across Cochrane, involving long days and late nights at work.
Cochrane’s coverage of COVID-19 reviews in 2020 was broad and responded to the needs of guideline developers. Our reviews examined the effectiveness of public health measures such as quarantine, PPE, ash for hand washing, universal screening, travel control measures and digital contact tracing in controlling COVID-19. We also published a qualitative review of barriers and facilitators of healthcare workers’ adherence to infection and prevention control, and scoping reviews looking at school measures to control COVID-19 and ICU care bundles for improving patient outcomes.
Reviews of diagnostic test accuracy were another major feature of our COVID-19 response, examining the diagnostic accuracy of antibody tests, signs and symptoms, thoracic imaging, routine laboratory tests and rapid, point of care tests.
As high-quality data from trials of COVID-19-specific therapeutics were slower to emerge, so were reviews of these interventions. We published reviews of convalescent plasma and hyperimmune immunoglobulin, and anticoagulants. The mental health of particularly impacted populations was also addressed by our reviews Interventions to support the resilience and mental health of frontline health and social care professionals during a disease outbreak, epidemic or pandemic and following de-escalation and Video calls for reducing social isolation and loneliness in older people.
Several of these reviews were updated multiple times during the course of the year (e.g. quarantine, convalescent plasma, thoracic imaging).
The above reviews were managed centrally, but others were published via Cochrane Review Groups, including a suite of reviews on mouth washes and sprays for preventing COVID infection, oxygen targets during ventilation and an update of a review of physical interventions to reduce the spread of respiratory viruses.
We were very much, and quite rightly in my view, in ‘response mode’ in 2020, attempting to address the urgent needs of our stakeholders. But now we can take stock, look at our emerging priorities and plan for the future."
What key priorities are set out in the paper?
Toby: "We identified important public health intervention and diagnostic accuracy reviews last year, so keeping those up to date is important. We are also looking to expand coverage in three areas relating to vaccination and immunity, generic medicines, and mental health consequences of the pandemic.
We would also do well to look back as well as forward. In the years after the influenza pandemic of 1918, there was an increase in neurological conditions thought to be related to the influenza virus. In a similar vein we can expect long term health consequences of COVID 19 to emerge years from now. Priorities will continue to shift but the need for evidence is fixed. To ensure that the evidence we can provide is relevant, we need to be flexible and move with what we know is happening.
Varied as these topic areas are, they each serve to highlight how misinformation and inequity have exacerbated and lengthened the course of the global pandemic. Addressing them will require no shortage of effort or evidence. To be relevant to the challenges ahead, our response to COVID 19 is not just about what we cover, but how we cover it. Where possible we want to see our reviews adopt an equity perspective to ensure that we can inform health and policy decisions."
How will these priority areas shape what Cochrane publishes?
Toby: "They will keep us on track to ensure our output is focused and relevant to what we know are the most important considerations for health systems globally. Since the start of 2020 I think we’ve got a better sense of what we need to stay on top of, but we’ve also seen how quickly gaps in coverage can emerge as new interventions and diagnostic tests are promoted and used. The need for effective treatments and tests has stressed efforts to evaluate these things properly, so balancing speed and rigour has become ever more important for us.
The collaborative work between all parts of Cochrane in response to COVID 19 needs to continue for us to continue to meet the information needs of our users. Working closely with CRGs as we have done in responding to COVID 19 so far shows how effective we are as a team in Cochrane. For the collaboration to truly pay off, we also need to reduce unnecessary duplication of effort, and so we recommended surveillance of what other review producers are doing."
If you look back in five-years-time, what will you most proud and pleased to have achieved in response to the pandemic?
Toby: "I think seeing the reviews coming through to publication having worked with Helen to put together an editorial team and process so quickly. Something profound was happening as so many people from across the community found a connection with us and with each other through this process. To know that all of this was happening against a backdrop of great turmoil and isolation from colleagues, friends and family was humbling."
Helen: "I feel proud of the number of reviews published and the speed at which this was achieved, despite such stressful circumstances. The Central Editorial Team have managed the editorial process for 29 COVID-19 reviews and updates to date, and this shows no sign of slowing down. Seeing the number of times these reviews have been shared and cited makes me feel that we may have made a real contribution to evidence-based decision making during the pandemic.
What makes me most pleased is that when we could have felt at our most isolated, we came together as a global team and supported one another. I feel much closer to my colleagues after the past year and consider them friends."
Over a 12-week period from March to August 2020, we drew together reflections about what external stakeholders thought about Cochrane’s initial response to COVID-19 - you can read the External Stakeholder Evaluation of Cochrane's COVID-19 response here.

Cochrane launches Cochrane Kenya to promote evidence-informed decision making in healthcare in the country
Cochrane is pleased to announce that on June 8, Cochrane Kenya launched at the 11th KASH (Kenya Medical Research Institute Annual Scientific and Health) Conference.
Cochrane Kenya is a geographical affiliate of the global Cochrane collaboration. It is also part of Cochrane Africa, a regional, independent Cochrane network of researchers, professionals, patients, carers, and people interested in health in Africa. Cochrane Kenya will promote evidence-informed decision making in health care in Kenya by supporting and training new authors of Cochrane Reviews, as well as working with clinicians, professional associations, policy makers, patients, and the media to encourage the dissemination and use of synthesized or summarized evidence.
Judith Brodie, Cochrane’s Interim Chief Executive Officer, said of the launch: “I am delighted we are announcing the launch of Cochrane Kenya, which I’m confident will deepen and expand the reach and impact of Cochrane activities, extending access to the best evidence for health and healthcare decision-making in East Africa, and therefore improving lives for citizens in Kenya and this region.”
The launch was well-received at the Conference, with Charles Wiysonge, Director of Cochrane South Africa, saying, "Cochrane Kenya will make an impact in Kenya, in Africa and globally. It could not have been born at a better time."
"COVID-19 highlights the hunger for rapid evidence to inform decision making. Cochrane Kenya will actively advocate for evidence-informed healthcare in Kenya & the East African region," said Eleanor Ochodo, from the Kenya Medical Research Institute and Centre for Evidence Based Health Care at the launch.
Cochrane Kenya is part of Cochrane, a global independent network of researchers, professionals, patients, carers and people interested in health. Cochrane produces reviews which study all of the best available evidence generated through research and make it easier to inform decisions about health. Cochrane is a not-for profit organization working to produce credible, accessible health information that is free from commercial sponsorship and other conflicts of interest. Cochrane’s work is recognized as representing an international gold standard for high quality, trusted information.
Can you tell us a bit about yourself and background?
My name is Jennifer Ma (I go by Jen). I am a researcher by training and did my PhD in the Stem Cell Bioengineering lab at the University of Toronto. I originally planned to stay in research and contribute to innovations in healthcare, but gradually discovered the crucial role of science communication to bring the existing body of knowledge to the public. Examples were all around me: friends were choosing alternative medicine over evidence-based treatments; unproven and dangerous “stem cell therapies” were masquerading as Regenerative Medicine and thriving; the anti-vax movement was gaining more followers by the day. I wanted to use my education, combined with my passion in visual arts, to fight misinformation and promote engagement with science. I also hope to reach an audience that might have been missed by traditional science media and connect with them at a human level. After finishing grad school, I am now focusing mostly on my science communication project Gentle Facts and loving every minute of it!
And how did Gentle Facts get started? Can you explain the focus?
I was finishing up my PhD thesis during the pandemic. It was a very stressful time so, to stay sane, I shielded myself from all other stressors from the outside world, including the constant bombardment of information about COVID-19 and the polarization of opinions online. However, being uninformed prevented me from doing my part as a citizen and a researcher/science advocate to fight the pandemic and other social issues, leaving me with feelings of guilt and powerlessness.
I saw that many others had similar sentiments: struggling to find a balance between staying in these important conversations and protecting our mental health. Gentle Facts is my attempt to be the solution, where we curate concise, actionable, evidence-based information and present them in an accessible way without drama. We hope that our mindful approach will lessen the mental toll and empower people to take informed actions more confidently.
What’s your goal for Gentle Facts?
Our main goal is to create social change through compassionate science communication. The current infodemic and increasingly hostile environment online means people are often talking over each other and nobody is actually listening. We believe an empathy-driven approach is necessary to facilitate constructive conversations and inspire positive actions. Gentle Facts creates a space where our audience’s emotions, especially those who feel drained and overwhelmed, are validated and cared for. We address their concerns through concise, evidence-based, and actionable information and empower them to create change together as a community.
You use art to communicate health evidence and science. What do you think about this intersection?
Appealing visuals really help catch people’s attention. But art can be so much more than just a “pretty face” for science content. Art is an amazing medium for expressing and evoking emotions. There is plenty of evidence that scientific facts and emotions both play an important part in our decision making process. Art and Science, therefore, work well together to connect, inform, and motivate towards common goals—what we aim to achieve at Gentle Facts. By relating evidence and emotions through art and compassion-driven communication, we hope to reach and connect with audiences who do support science but are usually disengaged.
What do you see as a challenge for evidence-based information on social media?
Social media is an interesting place where both good and bad are exponentially amplified. It can bring some people together while dividing others, provide high quality resources and spread misinformation on the same platform. Therefore, one critical piece of the puzzle is to boost the positive signals. Create evidence-based content that is engaging and sharable. Promote scientific and media literacy through education. Help people connect with each other by facilitating conversations and building communities. I believe with the right training, everyone can practice compassionate science communication, and we need all hands on deck to beat the infodemic.
Recently you illustrated the Cochrane review on walking for hypertension. Why did you pick this review and what did you want to get across?
I picked this review because it aligns very well with Gentle Facts’ principles: compassionate, factual, and actionable. It acknowledges and addresses the issue that exercising can be difficult for some people physically or mentally. The evidence collected is high in quality and includes participants with diverse backgrounds. It provides an easy-to-implement solution that most people can do. It is a great example of how evidence can empower people to take better care of themselves and contribute to public health.

Cochrane US talks about overabundance of information and how Cochrane is responding to the "infodemic"
The World Health Organization defines an infodemic as “overabundance of information – some accurate and some not – that occurs during an epidemic. It can lead to confusion and ultimately mistrust in governments and public health response”. This has been a particular challenge during the COVID-19 pandemic.
Cochrane US Senior Officer, Tiffany Duque, explains the current 'Infodemic', how to manage it, and how Cochrane is responding in this short video. This is an adaption of presentation given at the monthly CU Anschutz Medical Campus Rocky Mountain Cochrane Series (view the longer live webinar).
Cochrane is committed to supporting evidence-informed decision making through the production of high-quality, relevant, and up-to-date research syntheses.
Cochrane’s Governing Board is pleased to announce, with effect from 1 June 2021, the appointment of Judith Brodie as our new interim Chief Executive Officer. Judith will lead Cochrane as the organisation undergoes its search for a permanent CEO and ensure a smooth transition.

Governing Board Co-Chairs
Cochrane has submitted a statement to the 74th World Health Assembly, which is taking place virtually this week (24 May to 1 June).
The World Health Assembly (WHA) is the decision-making body of the World Health Organization (WHO) and is attended by representatives of all Member States.
Our statement emphasises the importance of clinical trial transparency within the context of global health crises, since it is not possible to make truly evidence-informed decisions without access to data from all clinical trials.
Read the full statement below:
Cochrane supports the Independent Panel’s report which identifies, alongside other strategies, evidence-informed decision-making as a clear route to ending the COVID-19 pandemic.
However, one barrier to evidence-informed decision making is a lack of access to clinical trial data. Despite this being an ethical, and often legal, requirement, an unacceptable number of trials still go unpublished within the required timeframe, making it impossible to get a full picture of the evidence. Such delays are even more crucial in a global health emergency.
Cochrane backs the joint statement made by WHO and the International Coalition of Medicines Regulatory Authorities (ICMRA) earlier this month highlighting this issue. We call on Member States to actively enforce these standards, and for clinical trial sponsors to take their obligations seriously. Requirements for transparent registration and reporting of clinical trials during health emergencies should also be considered within the pandemic treaty.
Cochrane is a strong advocate for clinical trial transparency. See below for recent updates in this area:
- Cochrane shows support for WHO-ICMRA statement on transparency and data integrity
- Cochrane signs letter asking medicines regulators in Europe to address unpublished clinical trials
- US FDA begins enforcement of clinical trial transparency regulation
- Cochrane Belgium partners on clinical trial transparency report
- Cochrane Austria launches joint trial transparency report
- Cochrane Sweden highlights under-reporting of Swedish clinical trials

- Free Webinar co-hosted by Cochrane Sweden: 'Clinical trial reporting and registration' on 16 June
Tuesday, June 1, 2021
Cochrane Belgium, together with TranspariMED, Test Aankoop and Kom op tegen Kanker, recently released a report detailing the status of clinical trial transparency in Belgium.
The report used data collected on the EU Trials Tracker, which monitors the status of clinical trials recorded in the EU Clinical Trials Register. According to EU legislation, clinical trial sponsors must post summary results to the register within one year of a study ending (or six months for paediatric trials).
Several clinical trial sponsors in Belgium with overdue results were reminded last year to update the registry. While some then took significant steps to upload missing data, others have made little progress.
22% of verifiably due trials were found to have not yet posted results on the registry. However, it is likely that far more trials are still missing results, since only 292 of 1,098 registered trials are marked as complete – including several which started over 10 years ago and are likely not still ongoing. Results from trials sponsored by universities and hospitals were also found to be missing more often than trials with commercial sponsors.
The paper also calls upon the Belgian medicines regulator, AFMPS, to ensure that information on trials is kept up to date and recommends that research funders in Belgium monitor trial reporting.
A follow-up report is planned in six months to track further progress on this issue.
Cochrane supports clinical trial transparency. We rely on the availability of results from clinical trials to produce high quality and relevant systematic reviews. When trial results are not published, it is not possible to make truly evidence-informed decisions about healthcare, and people can be put at risk of harm.
Interested in learning more on this issue? Free webinar on 16 June
Cochrane Sweden and Lund University are hosting a webinar on clinical trial registration and reporting on 16 June at 13:30-15:30 (CEST).
The session will be an opportunity to learn more about the ethical and legal requirements around trial transparency.
This Evidently Cochrane blog (originally posted here) is for all those involved in clinical trials. Katie Gillies and Derek Stewart, from the Trials Methodology Research Partnership and the Health Research Board Trials Methodology Research Network, highlight the need for focussed research on trial retention to help fill the evidence gaps identified in a national research agenda on retention to clinical trials developed and prioritised by all relevant stakeholders.
What do we know about the best ways to keep people involved in clinical trials? Frankly, not a lot.
Clinical trials can provide evidence about which treatments work. Clinical trials are research studies that involve people and compare different groups of people receiving different treatments and look at which treatments improve outcomes (like pain) the most. During the design of a trial, calculations are made about how many people need to join the trial and complete all of the data collection requirements (which might be, for example, a questionnaire or a clinic appointment). These calculations allow the researchers to be confident in the results at the end of the trial.
If there are problems with keeping people involved in a clinical trial this can often result in a delay in completing the trial or problems in using the results to make informed decisions about clinical care. Identifying ways to keep people involved in trials, i.e. they provide all of the data or measurements that the trial needs, has been identified as one of the top priorities for research into the design and delivery of clinical trials.What is already known about retention to clinical trials?
So, we don’t know a lot about how to keep people in trials but we do know a little. What we do know focuses on how to get trial participants to return postal questionnaires. Evidence from a recent Cochrane Review Strategies to improve retention in randomised trials (March 2021) suggests that some approaches may improve return rates of postal questionnaires. However, we we are not able to say with confidence that any of the results we found is a true effect and not caused by other factors, such as flaws with the design of the studies. As such, the effect of ways to encourage people to stay involved in trials is still not clear and more research is needed to see if these retention methods really do work. Of the 70 relevant articles we identified only two of those investigated how best to encourage people to attend clinical visits as part of the trial follow up. Of the studies included in the Cochrane Review on strategies to improve retention to RCTs only a handful included patients as partners in their design – this needs to change. We should be involving trial participants in decision-making about how best to improve retention.Where should research teams focus efforts?
The Cochrane review did, however, identify key strategies that research teams should focus on. The first set of priorities requires replication of evaluations of existing interventions using high quality evaluations of to provide evidence as to whether such strategies are effective or not. These four strategies all focus on are:
- Monetary incentives: specifically, does giving a £5 gift voucher at same time as sending the questionnaire improve response to postal questionnaires.
- Return postage: several return postage strategies have been evaluated to improve response of postal questionnaire e.g. reply paid compared to second class stamps, business post etc. Ensuring participants are not out of pocket is key, but which strategy to evaluate could be decided by the patient partners involved in the trial.
- Pens: A number of studies have evaluated the inclusion of a pen with a postal questionnaire to improve response. It looks promising but further studies, specifically in trials that include younger populations with participants who are men are required.
- Electronic reminders: emails or text messages reminding people (so sent in advance of the questionnaire) may also have an effect on postal questionnaire return. High quality replications are required.
These evaluations will help to provide evidence for trial teams as to what works to improve responses to postal questionnaires. They will begin to answer some of the questions identified as the top priorities for trials methodology retention research from a priority setting partnership (PSP) designed and delivered in association with the James Lind Alliance (JLA), the PRioRiTY II project. These prioritisation exercises help researchers and funders to focus on what matters most to all of those involved and ultimately contributes to global efforts to minimise waste in research by focussing activities. Future efforts to improve retention in trials should aim to target at least one of these stakeholder agreed priorities.
The past year has shone a bright light on the importance of clinical trials to provide evidence to inform health care decision making, But trials are only valuable if they recruit and retain enough people so that meaningful conclusions can be drawn from the results. Focussing efforts on keeping people in trials is effort well spent and will result in more valid and reliable result son which to base decisions for all.

Lifeology’s tagline is ‘The place where science and art converge’. They offer a platform that brings together scientists, artists, and storytellers to help people better understand and engage with science and health information and research. One of the main ways they meet their objectives is through beautifully illustrated, science-backed, bite-sized ‘flashcard’ courses about science and health-related topics aimed at the general public and students. We spoke to Paige Jarreau, VP of Science Communication at LifeOmic and co-founder of Lifeology more about their work.
Can you tell us a bit more about yourself?
My name is Paige Jarreau and I am VP of Science Communication at LifeOmic, a health software company. I am the co-founder of Lifeology (a LifeOmic product) along with Doryan Algarra, the VP of Design at LifeOmic.
I am a scientist turned storyteller and science communication scholar. When I was a child, the first thing I ever wanted to be when I grew up was a poet (or a science fiction writer!). As I got older I settled on a more “practical” career path as a doctor or a biomedical engineer - I imagined creating artificial organs and implants. But many years later I was enrolled in a PhD program in biomedical engineering when I realized that writing and creative expression needed to become my priority again, for my own mental health and fulfillment. From there, I never looked back. I started science blogging and ultimately got my PhD in Mass Communication studying science communication in new media environments.
Over the past decade, my interest in creative science communication has slowly morphed from primarily written to visual methods and formats. For example, I became interested in how scientists’ “selfies” on Instagram could help people see them as more human and trustworthy! I became interested in how art could make science more relatable to people. Meeting and collaborating with Doryan at LifeOmic was a turning point in my change in perspective of what good science communication looks like. We founded Lifeology on the idea that art is a critical, foundational aspect of engaging and accessible science communication - but that scientists struggle to create this art on their own.
How did Lifeology get started?
Lifeology, a platform that combines science and art, was the brainchild of my friend and coworker Doryan Algarra, VP of Design at LifeOmic. Over the course of his time at LifeOmic, Doryan has worked on the design of all kinds of products that facilitate precision medicine and wellness. In this work, he has realized that science and health information is often presented in overly complex and technical ways, or in outdated ways such as doctors’ office brochures that are not accessible and inclusive, much less interesting and beautiful to look at. Before developing the idea of Lifeology, Doryan had also been inspired by a book he was reading on epigenetics, of all things. Doryan generally felt that the book was complex and hard to follow. But he remembers one particular chapter to this day that helped the concept of epigenetics finally “click” for him. The chapter started with a question and then told a story about how some bees become queens and the rest become workers - based on different diets that affect the expression of their DNA! This got Doryan thinking about how even small storytelling devices and metaphors could help him understand and remember science that he thought was too difficult and niche for him to understand, let alone enjoy! As a designer, he quickly began imagining how these metaphors, and the “invisible” factors of epigenetics, could be made visual for even more impact.
Fast forward a few months, and Doryan had designed a prototype of what we know as Lifeology “flashcard” courses today. By giving art and science the same “real estate” on each “flashard” and making these courses easy to access and fun to interactively navigate on a phone, he hoped to make science and health information less intimidating and more inviting. He hoped to make science and health information more accessible to all people, including people who might be distrustful of or put off by science.
When Doryan showed me his Lifeology prototype, I was in awe. Like Doryan, I saw in these flashcard courses an innovative and fun way of delivering science information to broad audiences. But in talking through how courses would be created, we also began to see an opportunity to bring scientists and artists together to create the content as a team. Working together (a designer with a science communicator!) we became convinced that sci-art collaboration had to be a core feature of Lifeology courses. Today, we and the rest of the Lifeology team are baking collaboration tools and community into our platform to allow scientists, storytellers and artists to easily work together in the creation of Lifeology courses for broader audiences. We do this through cloud-based software collaboration tools but also processes and educational materials that help scientists and artists successfully collaborate to create better science communication.
What does Lifeology do?
Lifeology is a platform and communication tool that engages broader audiences in science, health and research in a fun, accessible way. We do this by bringing together science and art in our bite-sized digital “flashcard” courses. We designed these courses and their creation process to engage populations underserved by many science communication efforts - people with low literacy for example, and populations who tend to mistrust healthcare, science and government. Self-paced learning, empathetic storytelling and inclusive visuals are some of our key elements.
But we also believe that science communication in any format, including our flashcard courses, is far better when it is the product of collaboration between scientists and professional creatives like storytellers and artists. That is why we embedded within the Lifeology platform a growing community of storytellers, translators and artists from all over the world who want to collaborate with scientists. We have over 800 members in this community today! Our Lifeology platform guides scientists and other experts through successful collaborations with storytellers and artists as they create Lifeology courses together.
Teaching people the skillset to communicate science seems important to Lifeology. Can you tell us more?
Absolutely. While there are many tools out there that try to make it easier for scientists to create visual content to communicate their work, no tool can replace the need for collaboration and empathetic storytelling. To help scientists be successful in creating engaging, accessible and inclusive Lifeology courses (or other other science communication products!), we try to teach them key science communication skills, from knowing their audience, to how to tell a story, to how to be inclusive, to how to work with artists. One way we are doing this is through our Lifeology University SciComm Program, a free series of Lifeology courses and activities that help scientists become better communicators!
What advice do you have for researchers who want to communicate their review findings out?
Our most important piece of advice is to collaborate! Collaborate with members of the communities you are trying to reach with communication of your findings. Get to know your audience and involve them in the creation of culturally relevant content. Collaborate with community leaders. Collaborate with storytellers and artists who excel at creating content that connects with people on an emotional as well as a cognitive level.
The World Health Organization has said that in addition to dealing with a global COVID-19 Pandemic we are also dealing with a Pandemic with all the misinformation being spread. What do you think about this?
Misinformation around COVID-19 has certainly become its own pandemic or “infodemic.” The uncertainty, anxiety and fear that have surrounded the spread of COVID-19 have only accelerated this spread of misinformation. Uncertainty, anxiety and fear drove people to seek their own answers to questions that science didn’t have clear answers to yet.
In my mind, the only way to deal with this, from a science communication perspective, is through transparency, empathy and storytelling that is driven by data but also by local knowledge systems. It takes two-way communication and not making people feel bad for falling for misinformation, while also clearly and accessible presenting what we know now and solutions that people can actually put into practice locally.
There is also plenty that each of us can do to double-check what we read online and to prevent spreading misinformation.
Plans are in the works for some future collaborations between Cochrane and Lifeology. What are your thoughts on this?
We are so excited to collaborate! We hope to produce beautifully illustrated and accessible educational content around the topic of infodemics and what we can all do to prevent the appearance and spread of misinformation.

Pressure ulcers, also known as pressure sores or bed sores, are wounds to the skin and underlying tissue caused by prolonged pressure or rubbing. People who have mobility problems or who lie in bed for long periods are at risk of developing pressure ulcers.
Cochrane Wounds has recently published a suite of reviews on this topic, lead author Chunhu Shi tells us about these reviews.
How did this suite of reviews come about?
The relative effectiveness of different types of beds and mattresses (support surfaces) for preventing pressure ulcers prevention came out as a “top uncertainty” in a priory setting exercise involving patients, carers and health care professionals. We were awarded funding from the National Institute for Health Research to review the research on this topic.
In the beginning, we thought we would update an existing, large Cochrane review, Support surfaces for pressure ulcer prevention. This review was one of our most downloaded, with 11,835 downloads in 2019. However, we were concerned that the existing review was too large and difficult for readers to navigate. Furthermore, its size and complexity made it difficult to update. We therefore decided to split the review into four new review titles plus an overview that would include a network meta-analysis, to pull all comparisons together.
Before embarking on the splitting and restructure of the review, we consulted users of our reviews via an online survey. In the survey we explained the rationale for splitting the review and outlined our suggested new review titles and comparisons. Our stakeholders were positive about the plan so we proceeded to split the original review into four new reviews plus an overview.
Whilst addressing the evidence for pressure ulcer prevention we decided to also update our review of the effects of support surfaces for the treatment of pressure ulcers and include these data in the overview. In doing this we hoped to create a “one-stop-shop” on the evidence for support surfaces.
What led to these topics being picked?
Support surfaces such as beds and mattresses are widely-used and the focus of recommendations in pressure injury guidelines globally. However, decision-makers are faced with a confusing array of devices to choose from and consequent uncertainty. In splitting the review, we aimed to ensure each new review was as clinically comprehensive and relevant as possible. We used the support surface classification of the (US) National Pressure Injury Advisory Panel to structure our reviews, ensuring international, as well as national relevance.
Tell us about the prioritisation exercise
Full details about the priority setting exercise can be found here. Briefly, The James Lind Alliance approach is open and participatory. Patients, carers and health care professionals worked together to identify and rank the key ‘uncertainties’ that would benefit from research (including systematic reviews). More than 450 uncertainties were submitted to the Pressure Ulcer Partnership and these were crystallised into a top 12. Support surfaces for pressure ulcer prevention was ranked at number four.
Who are the reviews particularly useful for? Does any of the evidence stand out as useful for those caring for people with pressure ulcers, or those who have ulcers themselves?
We think these Cochrane reviews plus the overview are relevant to anyone making choices about using support surfaces to prevent and treat pressure ulcers, including carers and people at risk of (or who already have) pressure ulcers.

Featured review: Internet-based cognitive and behavioural therapies for post-traumatic stress disorder (PTSD)
Why was this review important?
Post-traumatic stress disorder, or PTSD, is a common mental illness that can occur after a serious traumatic event. Symptoms include re-experiencing the trauma as nightmares, flashbacks, and distressing thoughts; avoiding reminders of the traumatic event; experiencing negative changes to thoughts and mood; and hyperarousal, which includes feeling on edge, being easily startled, feeling angry, having difficulties sleeping, and problems concentrating. PTSD can be treated effectively with talking therapies that focus on the trauma. Some of the most effective therapies are those based on cognitive behavioural therapy (CBT). Unfortunately, there are a limited number of qualified therapists who can deliver these therapies. There are also other factors that limit access to treatment, such as the need to take time off work to attend appointments, and transportation issues.
An alternative is to deliver psychological therapy on the Internet, with or without guidance from a therapist. Internet-based cognitive and behavioural therapies (I-C/BT) have received a great deal of attention and are now used routinely to treat depression and anxiety. There have been fewer studies of I-C/BT for PTSD, yet research is expanding and there is a growing evidence base for their efficacy.
We spoke to lead author; Natalie Simpson who said "We’re living through unprecedented times, and whilst we cannot yet be sure of the full impact of the COVID-19 pandemic, an increase in PTSD lived experience is expected. Literature highlights the COVID-19 pandemic as a turning point for increased e-Health, though a drive towards improving access to psychological therapies was of course evident pre-pandemic, with an increasing number of internet-based interventions in use to treat mental health conditions, including PTSD.
The findings of this review are therefore important to understand the growing evidence base of internet-based therapies for PTSD, and particularly timely given the necessities to provide ‘COVID-proof’ treatment options, and alternatives to face-to-face therapies. The efficacy of internet-based cognitive and behavioural therapies for PTSD is evident, with guided, rather than non-guided interventions, and trauma-focused, rather than non-trauma-focused interventions, found to be more effective in reducing PTSD symptoms.
Further studies are however needed and it was encouraging to find many planned and ongoing studies."
Who will be interested in this review?
- People with PTSD and their families and friends
- Professionals working in mental health services
- General practitioners
What questions did this review try to answer?
In adults with PTSD, we tried to find out if I-C/BT:
- was more effective than no therapy (wait list);
- was as effective as psychological therapies delivered by a therapist;
- was more effective than other psychological therapies delivered online; or
- was more effective than education about the condition delivered online, at reducing symptoms of PTSD, and improving quality of life; or
- was cost effective, compared to face-to-face therapy?
Which studies did the review include?
We searched for randomised controlled trials (clinical studies where people are randomly put into one of two or more treatment groups) that examined I-C/BT for adults with PTSD, published between 1970 and 5 June 2020.
We included 13 studies with 808 participants.
What did the evidence from the review tell us?
- Analyses including 10 studies found that I-C/BT was more effective than no therapy (waiting list), at reducing PTSD. However, the quality of the evidence was very low, which means we have very little confidence in this finding.
- Analyses including two studies found there was no difference between I-C/BT and another type of psychological therapy delivered online. However, the quality of the evidence was very low, which means we have very little confidence in this finding.
- One study found that face-to-face non-CBT was more effective than I-C/BT. However, baseline levels of PTSD symptoms were not controlled for and the quality of this evidence was very low, which limits our confidence in this finding.
- We found no studies using standardised or validated measures of acceptability to tell us whether people who received I-C/BT felt it was an acceptable treatment.
- We found no studies that reported the cost-effectiveness of I-C/BT.
What should happen next?
The current evidence base is growing but still small. More studies are needed to decide if I-C/BT should be used routinely for the treatment of PTSD.
In this author interview we find out more about this recently published Network Meta-analysis, New generation antidepressants for depression in children and adolescents. Authors Dr. Sarah Hetrick and Nick Meader tell us about this work.
What were you trying to find out with this Network Meta-Analysis?
We were trying to find out how well newer generation antidepressants work compared with placebo and if some are more effective than others. We wanted to know how these antidepressants affect:
- symptoms of depression;
- recovery: no longer meeting diagnostic criteria for major depressive disorder;
- response or remission: scores on a scale indicating an important reduction in depression or no longer experiencing depression;
- ability to function in daily life;
- suicide-related outcomes; and
- whether they cause any unwanted effects in children and adolescents.
What is included in this review?
The review includes randomised controlled trials that test the efficacy of newer generation antidepressants compared with placebo in children and adolescents with depression. New generation antidepressants are those that have been developed recently. They are sometimes referred to as ‘second-‘ and ‘third-generation’ antidepressants; they do not include older formulations (tricyclic antidepressants or monoamine oxidase inhibitors).
Who will be most interested in this research?
People who support young people with depression, including both family and informal supports as well as clinicians who provide therapy and those who are able to prescribe medication.
In summary, what does the evidence in this review tell us?
Most newer antidepressants probably reduce depression symptoms better than a placebo (a 'dummy' treatment that does not contain any medicine but looks identical to the medicine being tested). However, the reduction is small and may not be experienced as important by children and adolescents, their parents and caregivers, or clinicians. When different medications are compared against each other, there may be only small and unimportant differences between most of them for the reduction of symptoms.
Our findings reflect what happens on average to individuals, but some individuals may experience a greater response. It is also the case that some people may experience a small change as important. This might lead to recommendations being made for the use of antidepressants for some individuals in some circumstances. Our findings suggest that sertraline, escitalopram, duloxetine, and fluoxetine can be used if medication is being considered.
We found small and probably negligible improvements in depression symptoms for newer antidepressants compared with placebo. We found differences between newer antidepressants were also probably negligible.
The evidence, as a whole, was limited. But for the effects of newer antidepressants on suicidal behaviour, there was even greater uncertainty. Firstly, children and young people at risk of suicide were often not included in these studies. So we can't be confident how newer antidepressants effect this group. Secondly, because suicidal behaviour is quite rare, future studies need to include more people before we can make firmer conclusions.
We found that selective serotonin reuptake inhibitor (SSRI) and serotonin-norepinephrine reuptake inhibitor (SNRI) classes of newer antidepressants may increase the risk of suicidal behaviour. But the impact on suicidal behaviour of most other newer antidepressant classes and most individual newer antidepressants was unclear.
How will this impact guidance and existing guidelines?
Our findings suggest sertraline, escitalopram, duloxetine, as well as fluoxetine (which is currently the only treatment recommended for first-line prescribing) could be considered as a first option. This larger range of first line options is a new finding and has implications for existing guidelines. This is in the context of the above findings of the reduction in depression being small and our uncertainty about how this reduction will be experience (as important or not) by young people taking the medication.
Guideline recommendations vary. For example, in the UK, NICE has recommended since 2005 that if an antidepressant is prescribed for children or young people, it should be fluoxetine.
However, our systematic review suggests there may now be negligible differences between fluoxetine and a number of newer antidepressants such as sertraline, escitalopram, and duloxetine. So these new findings may have implications for guidance in the future.
But these are complex judgements. Guideline groups will ultimately have to weigh up whether this new evidence sufficiently changes the balance of benefits and risks to warrant a change in practice. Similarly, we don't yet know whether differences we have judged to be small and unimportant are perceived that way by young people prescribed these medications.
For a clinician or parent making a decision about treatment, it’s a complicated area, especially if risk of suicide is being considered. How can this help people making these decisions?
It is important that those considering medication (including young people, their parents/families, and clinicians) understand that they may only experience a small change in their depression as a result of medication. It is also important that they know that there are several medications that they could try. What is very important is that if they do decide to take one of these medications, the impact of medication on depression symptoms should be closely monitored by those prescribing the medication, especially as suicide-related thinking and behaviour may be increased in those taking these medications. Close monitoring of suicide-related behaviours is vital in those treated with new generation antidepressants.
In this recently published Cochrane review, authors explored the effects of treating acute ischaemic stroke with endovascular thrombectomy and intra-arterial interventions.
First author Melinda Roaldsen said: "This review of endovascular thrombectomy for acute ischaemic stroke strongly reinforces the efficacy and safety of endovascular interventions. Endovascular thrombectomy is a treatment modality in rapid development and continues to gain significance in acute stroke care. This review finds high evidence that endovascular thrombectomy improves functional and neurological outcomes without increasing intracerebral haemorrhage or death. The benefit was seen with and without intravenous thrombolysis and was unrelated to age, sex, and time to treatment (though most trials are within 6 hours). Benefits were greater with more severe stroke. It is important to continue working towards making endovascular thrombectomy readily available for larger parts of the population."
This review addressed whether endovascular thrombectomy (removal of a blood clot in a blood vessel using a mechanical device) or intra-arterial thrombolysis (injecting clot-dissolving drugs directly into the clot), or both, provide better outcomes than standard treatment alone in stroke caused by a blocked blood vessel.
The majority of disabling strokes are due to a blockage of a large blood vessel by a blood clot in the brain. Such strokes lead to brain tissue damage because of oxygen deprivation. An ischaemic stroke is a stroke where the restriction of blood flow causes damage and death to the surrounding tissue due to oxygen shortage. For these patients, the most intuitive means of treatment is removal of the blockage by either injecting clot-dissolving drugs directly into the clot or removal of the blood clot using a mechanical device, or both. Prompt treatment can restore blood flow before major brain damage has occurred, leading to a good recovery. However, these treatments can also cause bleeding in the brain, which can result in poorer outcomes. The authors searched for randomised controlled trials (studies in which participants are assigned to one of two or more treatment groups using a random method) of both endovascular mechanical thrombectomy and intra-arterial thrombolysis to establish whether they are safe and effective treatments for stroke caused by a blocked blood vessel.

Review authors found 19 trials involving a total of 3793 participants. Treatment with endovascular thrombectomy can improve patients’ chance of survival with the ability to function well without increasing the risk of bleeding in the brain or death. It is still unclear what the optimal time window is within which treatment is beneficial and whether treatment is effective in the posterior (supplying the rear part of the brain) circulation. There is also a need to study whether a strategy of primary endovascular thrombectomy or intra-arterial thrombolysis, or both, is superior to a strategy where intravenous (injected into the vein) clot-dissolving treatment is provided first in a local centre followed by transfer of selected patients to hospitals able to perform mechanical thrombectomy or intra-arterial thrombolysis, or both.
Certainty of the evidence
The authors judged the available trials to be at low or unclear risk of bias, and so overall the evidence is reported to be of high certainty.
Cochrane, together with a range of other civil society organisations, has written to a group of medicines agencies in Europe asking that they take action to ensure trial transparency.
Despite an EU legislation requiring that results from clinical trials be published on the EU Clinical Trials Register within 12 months of a study ending, this information has not been shared for almost 30% of applicable trials.
The letter calls on the Heads of Medicines Agencies (HMA), a body of national regulators in Europe, to take action to address this serious issue and gives recommendations on how to improve the situation. This includes relatively simple steps like writing to the clinical trial sponsors whose results are overdue to remind them of their obligation to share a summary of their findings.
Dr Karla Soares-Weiser, Editor in Chief of The Cochrane Library and Acting CEO of Cochrane, said:
“Cochrane strongly supports efforts to ensure that data from all clinical trials are available and encourages HMA to take action on these recommendations. Without access to reliable information from all clinical trials, the evidence base on which to make judgements is incomplete – this limits the scientific community’s ability to learn from research findings and can lead to patients being harmed.”
