This list is for discussion of teaching, practice and implementation EBH. Evidence based health (EBH) is the integration of individual knowledge with the best available external evidence from systematic research in making decisions about health care. This list is for teachers and practitioners in EBHC to communicate with colleagues, announce meetings and courses, stimulate discussion, air controversies and aid the implementation of EBH. If you have a query about evidence concerning a specific clinical topic, please be aware that this is not the focus of this list, and you should look elsewhere first. If you do post a request to EBH, please include with your post a statement showing where you have already looked and what you have found. It is considered good manners to offer to repost a summary of what you find afterwards as well. Other general principles of netiquette apply to the list, particularly: i) Please be polite and respectful in your use of language ii) Please don't post attachments to the list.
