Resources for Systematic Reviews & Evidence-based Public Health Practice

What is Evidence-Based Public Health?

  • The process of integrating science-based interventions with community preferences to improve the health of populations. (Kohatsu ND, Robinson JG, Torner JC. Evidence-based public health: An evolving concept. Am J Prev Med. 2004 Dec;27(5):417-21.)
    • Evidence-based public health is defined as the development, implementation, and evaluation of effective programs and policies in public health through application of principles of scientific reasoning, including systematic uses of data and information systems, and appropriate use of behavioral science theory and program planning models. (Brownson, Ross C., Elizabeth A. Baker, Terry L. Leet, and Kathleen N. Gillespie, Editors. Evidence-Based Public Health. New York: Oxford University Press, 2003.)

Evidence-Based Practice Meta Search Site

TRIP (Turning Research Into Practice) Database
TRIP searches multiple EBM databases in one fell swoop. Databases listed in the following section that are included in TRIP are designated as such. Do you need to search the others if you search TRIP? The primary database will always have the most current information and some people feel more comfortable searching in the native interface. Having said that, try searching TRIP to see where the majority of the items come from, then go to the site and do one more search just to be sure. TRIP includes:

Suggested databases include:

Free Resources to search for systematic reviews

Cochrane Reviews (Cochrane Collaboration; abstracts free to public; included in TRIP)

Effective Health Care Program (US Agency for Healthcare Research and Quality [AHRQ]; included in TRIP)
The EPCs review all relevant scientific literature on clinical, behavioral, and organization and financing topics to produce evidence reports and technology assessments. These reports are used for informing and developing coverage decisions, quality measures, educational materials and tools, guidelines, and research agendas.

Bandolier (included in TRIP)
The impetus behind Bandolier was to find information about evidence of effectiveness (or lack of it), and put the results forward as simple bullet points of those things that worked and those that did not: a bandolier with bullets. Information comes from systematic reviews, meta-analyses, randomized trials, and from high quality observational studies.

EPPI-Centre (Social Science Research Centre, University of London)

Campbell Collaboration Register of Interventions and Policy Evaluations
“The Campbell Collaboration was founded on the principle that systematic reviews on the effects of interventions will inform and help improve policy and services. C2 offers excellent editorial and methodological support to review authors throughout the process of producing a systematic review. ” Reviews are in the areas of criminal justice, education, and social welfare.

PubMed link for the public (National Library of Medicine)

  • PubMed is free to the public. Searches will retrieve an abstract and links to the online FT when available.
  • Use the PubMed search filter that has been developed to help you find SRs.

Assessments of Effects

  • Technology Assessments (Agency for Healthcare Research and Quality) “AHRQ’s technology assessment program uses state-of-the-art methodologies for assessing the clinical utility of medical interventions. Technology assessments are based on a systematic review of the literature, along with appropriate qualitative and quantitative methods of synthesizing data from multiple studies.”
  • Centre for Reviews and Dissemination Databases(Centre for Reviews and Dissemination, University of York, UK)
    • Health Technology Assessment Database “The HTA database brings together details of completed and ongoing health technology assessments from around the world. The abstracts in the database are descriptive rather than analytical and do not form critical appraisals of the reports.” Limit your search to the HTA database by checking the box next to it.
  • Natural Standard (Natural Standard)
    “Natural Standard is an international research collaboration that aggregates and synthesizes data on complementary and alternative therapies.” More about this site…

  • Testing Treatments: Better Research for Better Healthcare
    “Aimed at both patients and professionals, Testing Treatments builds a lively and thought provoking argument for better, more reliable, more relevant research, with unbiased or fair trials, and explains how patients can work with doctors to achieve this vital goal.”

Economic Assessments

Search for Clinical Trials

On January 11, 2011, the BMJ published an editorial and an analysis written by members of the Cochrane Acute Respiratory Infections Group. The Cochrane members discussed issues concerning the importance of drawing on data from trials, not just those reported on in the research literature. The authors had earlier written a systematic review that reported favorably on Tamiflu based on a meta-analysis that included 10 trials, only 2 of which were reported on in the peer-reviewed literature. They were criticized for their analysis as they had not reviewed the actual data, so they contacted those involved with the trials to get the original data. However, they were unable to do so. Consequently, when they updated their review, they opted to not include the original meta-analysis. The article then goes on to discuss the importance of reviewing all trial data, not just those trials that are written up in the research literature.

This article is a must-read if you are considering a systematic review which involves clinical trials. If you decide you want to use original data from clinical trial, how do you find existing and past clinical trials? Take a look at these registries.

EBPH Meta-Sites

These sites provide additional links to EBPH resources. Many of the items listed on this page can be found on these pages as well.

Free Online Research Journal Collections

There are many sites that provide access to free research journals. As you review the sites, be sure to pay close to attention as to what is free. Some publishers restrict access by date—the most current issue is subscription-based only, for example. Some offer certain sections for free but other sections require a subscription. There may be overlap between these collections and some of the journals that are free may require you to register before viewing.
