Decision aids for people facing health treatment or screening decisions

2 months ago

A new Cochrane Library Editorial has been published about the history of a recently updated Cochrane review on healthcare decision aids and its implications for practice. There is also an accompanying podcast where you can hear the current lead author explain the need for the review and its latest findings in under four minutes.

Decision aids are one type of tool that can be used to support the process of shared decision making between patients and their health professionals, a key element of person-centred care and health system improvements. A major update to the landmark Cochrane review on decision aids has just been published with an analysis of 209 studies involving 107,698 participants. It provides clear evidence of the benefits of the use of decision aids over usual care across a huge array of health options, ranging from choices about cancer screening to decisions about major elective surgery.

An accompanying editorial describes the influence of this review on practice for over 20 years, with successive updates responding to the changing understanding of decision aids and shared decision-making over this time. The review has been referred to in more than 90 clinical practice guidelines and has been one of the most cited reviews published in the Cochrane Library for over a decade. 

With more convincing evidence of the benefits of using decision aids now available, the editorial discusses implications for practice and highlights some remaining challenges of implementing decision aids. This Cochrane review will continue to be updated and the authors hope to see the findings not only reflected in many guidelines but implemented across many health systems.

Celebrating Archie Cochrane

1 year 2 months ago

Cochrane is named in honour of Archie Cochrane, a British medical researcher who contributed greatly to the development of epidemiology as a science. 

Archie Cochrane is best known for his influential book, Effectiveness and Efficiency: Random Reflections on Health Services, published in 1972. The principles he set out in it so clearly were straightforward: he suggested that, because resources would always be limited, they should be used to provide equitably those forms of health care which had been shown in properly designed evaluations to be effective. In particular, he stressed the importance of using evidence from randomized controlled trials (RCTs) because these were likely to provide much more reliable information than other sources of evidence. Cochrane's simple propositions were soon widely recognised as seminally important - by lay people as well as by health professionals.

How can we have a rational health service if we don’t know which of the things being done in it are useful and which are useless or possibly even harmful? — Archie Cochrane

In 1979 he wrote, "It is surely a great criticism of our profession that we have not organised a critical summary, by specialty or subspecialty, adapted periodically, of all relevant randomised controlled trials." His challenge led to the establishment during the 1980s of an international collaboration to develop the Oxford Database of Perinatal Trials.

In 1987, the year before Cochrane died, he referred to a systematic review of RCTs of care during pregnancy and childbirth as "a real milestone in the history of randomized trials and in the evaluation of care", and suggested that other specialties should copy the methods used. His encouragement, and the endorsement of his views by others, led to the opening of the first Cochrane Centre (in Oxford, UK) in 1992 and the founding of  Cochrane in 1993.

Today Cochrane members and supporters come from 190 countries . We are researchers, health professionals, patients, carers, and people passionate about improving health outcomes for everyone, everywhere. Our global independent network gathers and summarizes the best evidence from research to help you make informed choices about treatment and we have been doing this for 30 years.

The 12th of January marks Archie Cochrane's birthday and it's a great opportunity to reflect on his contributions.

Making health decisions: Sarah’s story

1 year 4 months ago

Healthcare decision making can be complex – learn from Sarah’s personal story and make use of Cochrane resources.

Evidence-based healthcare is the integration of the best research evidence with clinical expertise and patient values. It is often represented with these three elements in a Venn diagram with these three equally important elements. However, decision making in healthcare isn’t always so neat and uncomplicated.  Cochrane systematic reviews contribute to the best available, current, valid, and relevant evidence in this process. Cochrane is also committed to helping others understand evidence-based healthcare and the role of evidence.

Sarah Chapman, a former nurse with a long career in health research, had progressive hearing loss since early adulthood. Recently she was faced with a life changing decision if she would like to go ahead with an optional cochlear implant. In this video with illustrations by Karen Morley, Sarah talks us through her personal story of healthcare decision making and how evidence and other factors fit into her thinking.

 

Sarah explains, “We are messy creature full of messy emotions, living complex lives, and it's in that space that we make our healthcare decisions. Understanding evidence and learning to spot which health information is trustworthy is important to all patients and caregivers – and Cochrane has the resources that can help with this.” You can learn more about Sarah’s in her personal blog, ‘From Ear to Eternity.’

Cochrane has a long and rich history of collaborating with healthcare consumers (patients, carers, and the public). Presenting our evidence in a way that is useful for people making decisions about healthcare and advocating for evidence in health and care is an important part of our work.

Cochrane’s Evidence Essentials is a free introduction to Evidence Based Medicine, clinical trials, systematic reviews, and how to use evidence when making decisions about your health. It was co-produced with patients and caregivers and it is presented a interactive and accessible manner.

Catherine Spencer, Cochrane CEO, says “For Cochrane to achieve its vision, producing high quality reviews of health evidence isn’t enough. Cochrane aspires to a world where all health decisions are informed by high-quality evidence – which means people need to first understand evidence and how to use it. As Sarah’s story shows, making health decisions can be complex. Cochrane’s Evidence Essentials helps people understand health evidence and how to use it. We hope that anyone new to the world of evidence-based healthcare will find this resource indispensable.”

What are diagnostic test accuracy reviews?

3 years 9 months ago

Cochrane systematic reviews can help us to make healthcare decisions based on up-to-date research evidence. They are systematic because they search for and analyse evidence in a systematic way, according to predetermined and published methods. Each systematic review answers a specific healthcare question by gathering all the relevant studies, assessing the reliability of these studies, then summarising their results to produce a summary of all of the available evidence.

One type of systematic review is a diagnostic test accuracy (DTA) review. In addition to investigating test accuracy, they ideally also investigate why the results may vary among studies, compare the performance of alternative tests, and help the reader to put the evidence in a clinical context. Watch the video below and read on to learn more about DTA reviews.

Cochrane DTA reviews are a type of systematic review that aim to evaluate the accuracy of diagnostic tests. They want to find out whether a new test is more accurate than an existing test, or whether it is quicker, cheaper or easier to perform. Answers to these questions help patients and healthcare workers make informed decisions about which test to use, based on up-to-date evidence. 

DTA reviews evaluate how well diagnostic tests (index tests) identify or exclude a particular disease or condition (the target condition). We know that diagnostic tests make errors, even when they are correctly performed. There are two types of test errors: false positive test errors (the index test suggests the target condition is present when it is not) and false negative test errors (the test suggests the target condition is absent when it is not). Cochrane DTA reviews can cover all types of diagnostic tests, from antibody tests to X-rays, for any disease or condition. It is really important that diagnostic tests provide accurate results so that people can receive prompt treatment or take preventive measures if necessary, and to avoid unnecessary testing, treatment and anxiety. 

DTA reviews search for all relevant test accuracy studies, appraise the studies for reliability, and combine their results. This gives the best possible estimate of the accuracy of an index test based on all the available evidence. DTA reviews are systematic because they search for and analyze evidence in a systematic way, according to predetermined and published methods.

Test accuracy studies most often report accuracy using sensitivity and specificity. 

  • Sensitivity means the proportion of people with the target condition who are correctly detected by the index test. 
  • Specificity means the proportion of people without the target condition who are correctly identified by the index test. 

Therefore, the nearer the sensitivity and specificity are to 100%, the better the test.

An alternative way to report test accuracy is using positive and negative predictive values, which tell us about the usefulness of a positive index test result and a negative index test respectively – this helps patients understand how reliable their test results are. Predictive values measure the number of positive index test results that will be true positives and the number of negative index test results that will be true negatives. The nearer the positive and negative predictive values are to 100%, the better the test.

Cochrane evidence in different languages

6 years ago

Only about 6% of the world’s population are native English speakers, and 75% of people don’t speak English at all.

Many people do not have access to high-quality health information, because it is not available in a language that they understand. We translate Cochrane evidence to make it more accessible, and to reduce the linguistic barrier to global evidence-informed health decisions.

Cochrane groups in different parts of the world lead our knowledge translation activities in different languages. They translate Cochrane Reviews and related content, such as podcasts or blogshots. They also produce and share information in their language, do social media, work with professional societies, policy makers, patient groups or the media in their country, and offer training.

We have published more than 49,000 translations of Cochrane health evidence summaries across 20 languages as of January 2024.

Read Cochrane evidence on cochrane.org in different languages. You can see all available languages on the top of each page on cochrane.org, and click on it to switch the language. Or click here:
