How have Cochrane EPOC reviews impacted on your work?

30 July, 2019

Dear colleagues

We would like to hear about the ways in which health systems and services decisions have been informed by findings from Cochrane EPOC reviews.

The Cochrane Effective Practice and Organisation of Care (EPOC) Group produces systematic reviews on health systems questions. This includes questions on governance, financial and delivery arrangements for health systems and on implementation strategies. A list of our protocols and reviews is available here:

To maintain and grow EPOC, we need to demonstrate to our funders and other stakeholders that EPOC reviews are having important impacts across the world. The information you provide will also help us to develop better ways of disseminating our reviews and ensure that our reviews address questions that you see as priorities.

We’d be grateful if you could provide information on this question: Are you aware of any examples of EPOC reviews being used to inform health systems decision making? These decisions could be at any level of the health system (e.g. international / global, national) and for any health issue.

You can share the information you have with us by choosing one of the following routes:

- Reply to describing in a couple of sentences any examples that you are aware of. We would be grateful if you could respond by 9 August 2019.

- Complete a short survey on this topic by clicking here: . This survey should take no more than 15 to 20 minutes, and we would be grateful if you could respond by 9 August 2019. Your responses will be collected anonymously unless you opt to share your personal details with us.

- Describe your examples to us in a short telephone or skype call. If you would prefer to arrange a call, please email

Please also forward this email to other people you think would be relevant responders.

We look forward to hearing from you!
