We have published more than 9,000 Cochrane reviews on a vast range of health topics. Our findings have changed health practice across the world, improving the survival rates of people with malaria, tuberculosis, breast cancer and traumatic blood loss, people in intensive care, premature babies, pregnant women, and many others.

Cochrane reviews go beyond emergency medicine. Our evidence has influenced how we are treated for back pain, depression, long Covid, eczema, Parkinson's and ADHD, to name a few. We have advanced routine care for many groups including women in labour, newborn babies, people who need blood transfusions, catheters or rehabilitation, those with mental health conditions, and elderly people who have had a fall or an infection.

We have improved treatments and quality of life for some of the most vulnerable in society: people with mental health conditions, histories of abuse or who are socially isolated. We work to make our findings accessible to different cultures and contexts, so that people from all backgrounds can benefit from them, especially those in low- and middle-income countries.

We have confirmed effective ways to prevent breast cancer, malaria, HIV/AIDS, tobacco-related diseases, obesity and other diseases, saving millions from suffering and loss. Prevention is better than cure.

We have examined existing procedures, such as pre-birth preparations, spinal cord stimulation and catheter changes, to check whether there is a strong basis for them. We have found some longstanding practices to be unhelpful – or even harmful – and many have been stopped. This has saved many people and health professionals from unnecessary procedures, and enabled better use of time and resources. For example, our review on ivermectin for preventing and treating COVID-19 showed there was no evidence to support its use. 

Our findings have influenced how people far and wide look after their health on a daily basis – such as what we eat, how we brush our teeth and the glasses we wear. We have provided guidance on how to exercise safely, give up smoking and alcohol effectively, and maintain and restore physical and mental fitness at all stages of life.

We have shown how to build health workers' resilence and reduce their stress in the face of COVID and other health crises. We have reviewed new tools and technologies, to see how they can be best harnessed to strengthen health care and systems. We have identified effective ways that patients can help improve the delivery and development of health services, and we have evaluated strategies to improve uptake of vaccines in low- and middle-income countries.
