We have opened the initial issue – April 2012 - of Systematic Reviews, an open access journal published by BioMed Central. This and subsequent issues can be access from the above url.
We have opened the BestBETS site which contains numerous Best Evidence Topics. Originally having a emergency medicine focus, BETs for cardiology, nursing and pediatrics now are included.
This slide discusses Best Evidence Topic (BET) Format. Each BET is analyzed with a 3 part question and answered with a standardized Report Format.
We have opened the SEARCH BETs option and completed a search for cardiac arrest. Note the color coded Status list for all the BETs.
This is an example of how each BETs record is displayed including the Three Part Question, Clinical Scenario, Search Strategy Search Outcome Relevant Paper(s) plus Comments.
A second option for accessing the material is to Browse BET Categories by Topic or Specialty.
A third option is to Search Critical Appraisals whichare one page summaries of the evidence related to a particular clinical question.
PubMed Health specializes in reviews of clinical effective research – which finds answers to ‘What Works’ in medicine and health care. It is based on systematic reviews of clinical trials. PubMed Health is a service provided by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).
From the Contents drop down menu, you can access PubMed Health’s information in the following categories: For consumers, Executive summaries, Clinical guides and Full text reviews. We will open the Executive summaries option. Note also that PubMed Health contains a Medical encyclopedia.

Question for next two resources • Both Trip Database and Evidence Updates are aggregators that search various EBM tools for results to keyword searches. • The problem is that the results are often resources that are fee-based and users are asked for their username and password or requested to pay a fee. • Do you think these should be included or excluded? Or should they just be mentioned in the bibliography at the end?
Trip Database is a clinical search tool for health professionals to identify quality clinical evidence for clinical practice. It allows simultaneous searching of multiple sites which speeds up the question answering process. Registration is required but free and gives the users additional resources.
