Cochrane Crowd, Cochrane’s citizen science platform, is a global community of volunteers who are helping to classify the research needed to support informed decision-making about health care.
The job of the Cochrane Crowd community is to review descriptions of research studies to identify and classify randomized controlled trials (RCTs), a type of study that is considered the gold standard for clinical trials. Reports of RCTs are then fed into Cochrane’s Central Register of Controlled Trials, helping Cochrane authors and other systematic reviewers around the world quickly find the evidence they need to determine whether a treatment works, or whether a diagnostic test is accurate.
A challenge held in partnership with the Cochrane Associated Centre at Sinaloa’s Pediatric Hospital (Mexico) and the Autonomous University of Sinaloa (Mexico) recently broke all previously held challenge records.
Giordano Perez-Gaxiola, director of Cochrane Mexico and key challenge organiser said; "I had run a couple of small challenges through Cochrane Classmate with my students in the past year. I thought it was a simple way to motivate them to learn what Cochrane is, what a clinical trial is, and how an easy-to-use platform like Cochrane Crowd could help them learn. A couple of months ago I had a meeting with the dean of the medical faculty of the Autonomous University of Sinaloa (Universidad Autónoma de Sinaloa, UAS), Dr. Gerardo Alapizco, to discuss how the university and our Cochrane Associated Centre at Sinaloa’s Pediatric Hospital (Hospital Pediátrico de Sinaloa, HPS) could collaborate. I proposed setting up a university-wide challenge in order to engage a large number of students. This would introduce them to Cochrane and hopefully pique their interest, potentially leading to further engagement with Cochrane. This proposal was then discussed and approved by the medical faculty’s governing committee. We agreed that all students at UAS would be invited to take part."
Over three days from Dec 5-8, 738 people signed up, 455 participated and 319,643 individual assessments were made equating to 89,692 records being screened. 90 people screened at least 1000 records during the challenge and as a result were invited to become Cochrane members. And finally, almost 10,000 RCTs were identified for Cochrane’s CENTRAL register of controlled trials, where they can be accessed by systematic reviewers around the world.
Perez-Gaxiola added; "In my opinion, a Cochrane Crowd challenge is a simple way to engage students, to help them learn about Cochrane and about clinical trials. It is very easy to set up (takes about 10 minutes) and easy for the students to participate. It can be a useful teaching tool, too. And if you make it a competition, it can be fun."
Featured Review: Adverse events in people taking macrolide antibiotics versus placebo for any indication
The review 'Adverse events in people taking macrolide antibiotics' asked, “Will people taking a macrolide antibiotic experience more adverse events than those treated with placebo?”
Macrolide antibiotics are one of many types of antibiotic. They are commonly used to treat both acute and chronic infections. The four most commonly used macrolides are azithromycin, clarithromycin, erythromycin, and roxithromycin. People taking macrolide antibiotics are at risk of experiencing adverse events such as nausea, diarrhoea or rashes.
Lead author of the review Malene Plejdrup Hansen explains, “This review was undertaken to quantify adverse events in patients using macrolide antibiotics, independently of the indication or effects of the treatments. The intent is to support clinicians and patients in evaluating harms as well as benefits in the choice of management when antibiotics are considered.”
The review includes 183 studies with 252,886 participants. Most studies were conducted in hospitals. Azithromycin and erythromycin were more commonly studied than clarithromycin and roxithromycin. Most studies (89%) reported some adverse events or at least stated that no adverse events were observed.
- People treated with a macrolide antibiotic experienced gastrointestinal adverse events, such as nausea, vomiting, abdominal pain, and diarrhoea more often than those treated with placebo.
- Taste disturbances were more often reported by people taking macrolides than those taking a placebo. However, very few studies reported on these adverse events, and results should be interpreted with caution.
- Hearing loss was more often reported by people taking macrolide antibiotics; however, only four studies reported this outcome.
- Macrolides caused less cough and less respiratory tract infections than placebo.
- We did not find any evidence that macrolides caused more cardiac disorders, liver disorders, blood infections, skin and soft tissue infections, changes in liver enzymes, appetite loss, dizziness, headache, respiratory symptoms, itching, or rashes than placebo.
- We did not find more deaths in people treated with macrolides than in those treated with placebo.
- Very limited information was available to assess if people taking a macrolide antibiotic were at greater risk of developing resistant bacteria than those treated with placebo. However, bacteria that did not respond to macrolide antibiotics were more commonly identified immediately after treatment in people taking a macrolide than in those treated with placebo, but differences in resistance thereafter were inconsistent.
The quality of evidence ranged from very low (cardiac disorders, change in liver enzymes, liver disorders), to low (abdominal pain, death, diarrhoea, dizziness, hearing loss, skin and soft tissue infections, taste disturbance, wheeze), to moderate (appetite loss, blood infection, cough, fever, headache, itching, nausea, rash, respiratory symptoms, respiratory tract infections, vomiting) according to GRADE assessment.

On Friday, 7th December, Cochrane enthusiasts gathered at the University of Split School of Medicine to celebrate the 10th anniversary of Cochrane Croatia.
Cochrane Croatia was founded as a Branch of the Italian Cochrane Centre on 8th December, 2008, ten years following initial discussions between Prof. Ana Marušić, Sir Iain Chalmers and Prof. Alessandro Liberati. Prof. Peter Tugwell, and his team, were instrumental in building capacity within Cochrane Croatia, along with the Mamić family who warmly welcomed several members of Cochrane Croatia into their family home, in Ottawa. Together, with the support of the Italian Cochrane Centre, later lead by Roberto D’Amico, Cochrane Croatia grew to become an independent Cochrane Centre in 2017.
Today, Cochrane Croatia has 20 members, 19 partner organisations, 1 Affiliate - with another two in the pipeline. The Anniversary celebration was opened by the Vice-Dean for Research at the University of Split School of Medicine, Prof. Mirna Saraga-Babić, and by Cochrane Croatia’s Co-Director, Dr. Tina Poklepović Peričić. This was followed by an address given by the Chancellor of the University of Split, Prof. Dragan Ljutić and by Prof. Stipan Janković, Dean of the medical school in Split at the time Cochrane Croatia was founded. Prof. Ozren Polašek, Director of Croatian Centre for Global Health, underlined the importance of systematic reviews and Cochrane’s crucial role in their production and dissemination. Prof. Žarko Alfirević, from Cochrane Pregnancy and Childbirth, shared how Cochrane reviews influenced his clinical practice.
The videos ‘Three patients and their stories contributing to Cochrane’s success’ and ‘Recognising success in Cochrane in 2017’ were screened. This was followed by Prof. Matko Marušić’s reminder of the early days of Cochrane Croatia, after which Cochrane Croatia’s Co-Director, Irena Zakarija-Grković, provided an overview of the first ten years, summarized in a published report ‘Cochrane Croatia: 2008-2018’. Finally, Dr Ljubo Znaor, Research Office Coordinator at the University Hospital Split, spoke of future projects with Cochrane Croatia.
All present celebrated Cochrane Croatia’s achievements with an appropriately decorated birthday cake and plenty of good cheer!

A common consequence for people who have a stroke is a reduction in their arm function. Various approaches are available to try to help and, in September 2018, the Cochrane Review for one of these, electromechanical and robot‐assisted arm training, was updated by a team of researchers from Germany. We asked lead author, Jan Mehrholz from Dresden Medical School, to tell us about the latest findings in this podcast.
"More than two‐thirds of people who have had a stroke have difficulties with reduced arm function. This can limit their ability to perform everyday activities and electromechanical and robot‐assisted arm training might help by using specialised machines to support shoulder, elbow and hand movements. Our review looks at the effects on arm function and muscle strength, and whether patients find it acceptable.
We identified 45 trials, involving a total of approximately 1600 participants; ranging from a trial with just eight participants to a US study with nearly 130. The trials assessed 24 different electromechanical devices, which were tested for between two and 12 weeks, and compared to a variety of other interventions.
Although the trials also used a variety of outcome measures, we can say that, on average, electromechanical and robot‐assisted arm training improves daily living for people after stroke, and improves the function and muscle strength of the affected arm. However, the effects were relatively small and might not be big enough to be seen as clinically important. Adverse events, such as injuries and pain, were seldom described, and so it does seem reasonable to include these devices in the rehabilitation of patients after a stroke but with some uncertainty about when and how often they should be used.
In summary, people who receive electromechanical and robot‐assisted arm training after a stroke might improve their activities of daily living, arm function, and arm muscle strength. However, although the quality of the evidence was high, we still need to be cautious because the benefits are small and there were substantial differences between the trials in the intensity, duration, and amount of training; and the types of treatment, participants and outcomes measurements used."
Omega-3 fats are the subject of more than two dozen Cochrane Reviews for conditions including cardiovascular health, dementia and gastrointestinal problems. In November 2018, the review on the effects on preterm birth when these are taken by pregnant women was updated. The review was led by Associate Professor Philippa Middleton and Professor Maria Makrides, from the Healthy Mothers Babies and Children theme at the South Australian Health and Medical Research Institute. Professor Makrides tells us about the latest evidence.
"In Australia, about 1 in 12 babies are born prematurely, this means that they are born more than three weeks before the usual 40 weeks of pregnancy. This is a problem because premature birth is responsible for around 85% of all health complications in early life and is the leading cause of death in children under 5.
There are very few strategies to prevent women from going into early labour and delivering a premature baby. However, one of the things that our research team has been studying is whether the omega-3 long-chain fatty acids, such as DHA and EPA that are found in fish and fish oils, can extend the length of pregnancy.
We have now completed our Cochrane systematic review that brings together all the published randomised trials that test the effects of these long chain omega-3 fats during pregnancy on the health of mothers and their babies. We included 70 studies, which contained more than 19,000 women in the trials. The review shows that there is high-quality evidence that supplementation with long-chain omega-3 fats during pregnancy, particularly with DHA, reduced the risk of having a premature baby by 11% and it also reduced the risk of having a very premature baby, born before 34 weeks, by 42%.
Based on these findings, we suggest that pregnant women with one baby take between 500 and 1000mg of long-chain omega-3s every day from the 12th week of pregnancy. It’s best if these supplements contain at least 500mg of DHA per day. As a result of the review, we are revising clinical practice guidelines for health professionals who are working in pregnancy care to try and encourage pregnant women to supplement their diets with omega-3s, to increase their chances of having a healthy full-length pregnancy."
The call for ‘Expressions of Interest’ to join the Cochrane US Network is now open. This call invites US-based organizations and institutions of different kinds to indicate their interest to support and/or join and become part of a new Cochrane US Network. The deadline for submitting an Expression of Interest is January 31, 2019.
This recently published Cochrane Review assessed which long-acting inhalers are the most effective and safest for people with advanced chronic obstructive pulmonary disease (COPD.)
Chronic obstructive lung disease (COPD) is usually caused by smoking or other airway irritants. COPD damages the lungs and causes airways to narrow which makes it difficult to breathe. The disease accounts for more than three million deaths annually and is the third leading cause of death world-wide, it is also a major cause of disability and hospitalisation. Quality of life can be poor as people find it hard to carry out everyday tasks
There are two types of inhalers for COPD: rescue and maintenance. A rescue inhaler is short- and fast-acting, and used as needed for quick relief of symptoms, whereas a maintenance inhaler is long-acting and used on a daily basis to relieve daily symptoms and reduce flare-ups. The long-acting inhalers are usually reserved for more advanced COPD.
Does it matter which long-acting inhaler is used in people with advanced COPD?
Commonly used maintenance inhalers are grouped into four different groups: long-acting beta2-agonists (LABAs); long-acting muscarinic antagonists (LAMAs); LABA/inhaled corticosteroid (ICS) combinations; and LABA/LAMA combinations. Combination inhalers are usually reserved for individuals whose single-maintenance inhaler, such as LAMA or LABA fails.
There are not many head-to-head comparisons to determine which treatment group or individual inhaler is better compared to the others. Preventing severe flare-ups and hospital admissions is especially important to people with COPD, healthcare providers, policy makers and society.
How did the review group answer the question?
We collected and analysed data from 99 studies, including a total of 101,311 participants with advanced COPD, using a special method called network meta-analysis, which enabled us to simultaneously compare the four inhaler groups and 28 individual inhalers.
What did it find?
- The LABA/LAMA combination was the best treatment, followed by LAMA, in preventing flare-ups although there was some uncertainty in the results.
- Combination inhalers (LABA/LAMA and LABA/ICS), are more effective for controlling symptoms than single-agent therapies (LAMA and LABA), in general.
- The LABA/LAMA combination was better than LABA/ICS combination, especially in people with a prior episode of flare-ups.
- The LABA/ICS combination had a higher incidence of severe pneumonia compared to the others.
- oWe did not find a difference in benefits and harms, including side effects, among individual inhalers within the same treatment groups.
The LABA/LAMA combination is likely the best treatment in preventing COPD flare-ups. LAMA-containing inhalers appear to have an advantage over those without LAMA for preventing flare-ups.
Combination inhalers (LABA/LAMA and LABA/ICS), appear more effective for controlling symptoms than single-agent therapies (LAMA and LABA). Inhaled steroids carry an increased risk of pneumonia.
Yuji Oba, lead author of this Cochrane review said, “ There are a range of different treatments for COPD, and this review provides a comprehensive assessment of how effective they are at preventing flare ups of COPD, managing symptoms and improving quality of life, but it also looks at important harms including the risk of pneumonia. The findings of the network meta-analysis feed in to guidelines published by NICE and are testament to a strong collaboration between Cochrane Airways group and the guideline group who have developed guidance on managing COPD.”
Cochrane Airways have published its biggest ever Cochrane Review. The meta-analysis review assesses which long-acting inhalers are the most effective and safest for people with advanced chronic obstructive pulmonary disease (COPD) and supports a recently published NICE guideline.
The logistics of getting such a large review done with time tight timescales have been an enormous challenge for the review team. We asked Rebecca Normansell, Joint Co-ordinating Editor and Emma Dennett, Managing Editor, Cochrane Airways, how this review came about and its potential impact.
How did the review come about?
We received a review proposal towards the end of 2015 from a chest physician in the USA, Yuji Oba, who had identified from his own practice an important clinical question about inhalers for COPD. He had already reviewed the literature and published on the subject, but was aware of new data and was interested in producing a Cochrane Review. He had assembled a team including a UK-based expert in network meta-analysis (NMA), Sofia Dias, with whom we had worked before. We agreed it was an important question, but needed to refine the comparisons in the NMA to minimise overlap with an existing Airways NMA and other reviews. After a bit of back and forth between the editorial base and the authors, we registered the title and the protocol was published in March 2017.
This is the biggest the airways group has done - how many people were involved, did it 'draw' on the team in a unique way?
The review was the biggest review we have ever done. Not only did it have 99 studies, but there were six pairwise comparisons, each with multiple outcomes, and network meta-analyses of multiple outcomes in both high and low risk COPD populations – a vast amount of data!
One of the challenges for the editorial team was the sheer volume of material to edit. We felt overwhelmed at times and making sure the review met the standards and all the data matched up throughout the review and the summary versions was time-consuming. Denise Mitchell, UK-based copy-editor, spent two weeks on it - copy editors are some of the unsung heroes in Cochrane!
While the payoff from working to get the review finished for the NICE guideline has been great, it was quite nerve-wracking. We are essentially trusting an author team to do what they said they will do, but without the control you would have of someone you are employing or paying to deliver a service. Yuji and Sofia were brilliant at keeping in touch with us and doing what they said they would in the timeframe.
What does the review mean? How will it inform policy or practice?
There is an overwhelming number of inhaled drugs licenced for use in COPD, and now multiple ‘fixed dose’ combined inhalers. Health care professionals and health services have to make difficult choices every day, balancing efficacy, safety, patient preference and cost. This huge review compared two single drug options – LABA or LAMA – to combined options – LAMA/LABA or LABA/ICS. The review found that one particular combination – LABA/LAMA – is probably the best treatment for reducing harmful flare-ups of COPD. LAMA containing inhalers (combined with LABA and on its own) are likely to have an advantage over those without a LAMA for preventing COPD flare-ups. Combined drugs appeared more effective than single drugs for improving symptom and quality-of-life scores. Importantly, ICS-containing inhalers were found to be associated with an increased risk of pneumonia – a potentially serious lung infection.
These are important findings that they give extra weight to the direction that most current guidelines are going – to favour LAMA-containing inhalers, especially for those having frequent flare-ups, and reserve ICS-containing inhalers for those who keep having flare-ups despite treatment, or have features suggestive of asthma. The next question is what are the risk and benefits of triple therapy, i.e. adding ICS to LAMA/LABA combinations? Cochrane Airways has just started a review update on this topic.
The other finding that may interest health care professionals and policy makers is that, in general, when the review authors looked at individual drugs within a class and at the class of drugs as a whole in the NMA, they found little difference. This suggests that drugs within a class are probably broadly equivalent, so perhaps other factors such as cost and patient preference can be considered when prescribing.
In terms of it appearing in guidelines, can you say a little about the history of this relationship? How does it build on what has happened before?
Back in 2016, we started the process of applying for a Cochrane Programme Grant, focussed on COPD. We were aware that NICE were working on a COPD guidelines update at the same time. We made contact with NICE to find out if there were sensible ways for us to work together and share resources. We had already had some contact with NICE in previous Programme Grants, and are registered stakeholders for their respiratory-related consultations.
We had a discussion and agreed that we would deliver one of our Programme Grant reviews, about long-term antibiotics for COPD, in time for the guideline and to share our data early – which we have done – the published review can be read here. But during the discussion, we also found out that NICE would be very interested in the findings of this NMA, which was about to be published as a protocol. We approached the author team to find out if they could deliver data and the finished review to the NICE deadline and we were delighted when they agreed to do their best. We kept in close contact with NICE and the author team over the following 18 months. We shared data from the NMA with NICE in January 2018 and were thrilled to be able to publish the finished review just a couple days before the guideline itself – phew!

This Special Collection of Cochrane Systematic Reviews brings together a large body of research on the accuracy of tests used to diagnose skin cancer.
The suite of eleven reviews was led by Dr Jac Dinnes at the University of Birmingham and supported by the Cochrane Skin Group and a team of over 30 researchers and expert advisors, funded by the National Institute for Health Research (NIHR).
The reviews summarise research evidence assessing the accuracy of different diagnostic tests to support clinical and policy related decision making in the diagnosis of all types of skin cancer.
Dr Jac Dinnes, of the University of Birmingham’s Institute of Applied Health Research, said: “Early and accurate detection of all skin cancer types is essential to manage the disease and to improve survival rates in melanoma, especially given the rate of skin cancer world-wide is rising.
The visual nature of skin cancer means that it can be detected and treated in many different ways and by a number of different types of specialists, therefore the aim of these reviews is to provide the world’s best evidence for how this endemic type of cancer should be identified and treated."
“We have found that careful consideration should be given of the technologies that could be used to make sure that skin cancers are not missed, at the same time ensuring that inappropriate referrals for specialist assessment and inappropriate excision of benign skin lesions are kept to a minimum.”
Key findings of the Special Collection were:
- Visual inspection using the naked eye alone is not good enough and melanomas may be missed.
- Smartphone applications used by people with concerns about new or changing moles or other skin lesions have a high chance of missing melanomas.
- When used by specialists, dermoscopy - a technique using a handheld device to zoom in on a mole and the underlying skin - is better at diagnosing melanoma than visual inspection alone, and may also help in the diagnosis of BCCs.
- Dermoscopy might also help GPs to correctly identify people with suspicious lesions who need to be seen by a specialist.
- Dermoscopy is already widely used by dermatologists to diagnose melanoma but its use in primary care has not been widely evaluated therefore more specific research is needed.
- Checklists to help interpret dermoscopy might improve the accuracy of diagnosis for practitioners with less expertise and training.
- Teledermatology - remote specialist assessment of skin lesions using dermoscopic images and photographs - is likely to be a good way of helping GPs to decide which skin lesions need to be seen by a skin specialist but future research needs to be better designed.
- Artificial intelligence techniques, such as computer-assisted diagnosis (CAD), can identify more melanomas than doctors using dermoscopy images. However, CAD systems also produce far more false positive diagnoses than dermoscopy and could lead to considerable increases in unnecessary surgery.
- Further research is needed on the use of specialist tests such as reflectance confocal microscopy (RCM) – a non-invasive imaging technique, which allows a clinician to do a ‘virtual biopsy’ of the skin and obtain diagnostic clues while minimising unnecessary skin biopsies. RCM is not currently widely used in the UK but the evidence suggests that RCM may be better than dermoscopy for the diagnosis of melanoma in lesions that are difficult to diagnose.
- Other tests such as using high frequency ultrasound have some promise, particularly for the diagnosis of BCCs, but the evidence base is small and more work is needed.
Cochrane Skin founder Professor Hywel Williams, of the Centre of Evidence-Based Dermatology at the University of Nottingham, said: “Completing this broad suite of detailed reviews was a real marathon.
“Apart from a few exceptions, I was surprised by how poor the overall study designs were, especially in terms of accurately documenting where on the clinical pathway patients were tested.
“Although some useful conclusions have emerged, for example, on the role of dermoscopy, the greatest value of the research is to serve as a yardstick for designing future studies evaluating skin cancer diagnosis techniques on patients who are typically seen in GP and specialist settings.”
The research team said that future studies evaluating diagnostic skin cancer tests should recruit patients with suspicious skin lesions at the point on the clinical pathway where the test under evaluation will be used in practice. Further research is also needed to evaluate whether checklists to assist diagnosis by visual inspection alone can improve accuracy and to identify how much accuracy varies according to the level of expertise of the clinician carrying out the assessment. Well-designed studies of dermoscopy in primary care are needed, and the best ways of delivering dermoscopy training need to be identified.
The reviews have been shared with The National Institute for Health and Care Excellence (NICE) to inform a potential update of the NICE Melanoma guideline, which was last updated in 2015.

World AIDS Day takes place on the 1st December each year. It’s an opportunity for people worldwide to unite in the fight against HIV, to show support for people living with HIV, and to commemorate those who have died from an AIDS-related illness. Founded in 1988, World AIDS Day was the first ever global health day.
Cryptococcal meningitis causes an estimated 15% of all AIDS‐related deaths globally. The disease largely affects people with advanced HIV disease, mostly in low‐ and middle‐income countries. The high death rate in part relates to limited access to diagnostic tests for the disease and the high cost and limited availability of treatments. A new Cochrane Library editorial has been published on this important topic; 'Updating guidance for preventing and treating cryptococcal disease: how evidence and decisions interface'.

Cochrane Colloquium, Santiago, Chile 22-25 October 2019
Cochrane Chile is delighted to be hosting the Colloquium next year. It will be a great opportunity to meet and network with the Cochrane community from Chile and Latin America, and to be surprised by the wide usage of Cochrane evidence in decision-making at all levels.
The theme of the next Colloquium is ‘Embracing Diversity’, and there is no better place to experience it. In 2018, Chile was recognized as the best country to visit by the prestigious Lonely planet travel guide. This long and narrow strip of land, isolated from the rest of the world by the soaring Andes to the east, and the vast Pacific Ocean to the west, acts as a catalogue of natural wonders, ranging from the unearthly scenery of the world’s driest desert in the north, to the world’s largest continental ice fields in the south. In between, countless unforgettable locations, including top-of-the-list wine growing regions, the clearest skies in the world, the impenetrable wilderness of Patagonia and the enigmatic Easter island, just to name a few. Chile is nature on a colossal scale, and travel is surprisingly safe and easy.
Accompanying Chile’s diverse geography is it’s multi-ethnic and diverse society. High-tech, early technology adopters, conforming what the media refers to as Chilecon Valley, coexist with writers that make Chile known as a country of poets, and nine indigenous peoples that have preserved their culture as a living heritage.
Registration is scheduled to open in February 2019 and abstract and workshop submission will launch in early January. Visit the website to get the latest information and key dates, with more details to be announced in the coming months.
