Systematic Reviews examine the quality, quantity, and consistency of the scientific evidence regarding the effectiveness of programs, policies, or initiatives.
Many organizations focus on conducting systematic reviews to continually examine the best available evidence of public health activities. Some examples include:
The Cochrane Database of Systematic Reviews
The Cochrane Library publishes systematic reviews related to a wide variety of public health topics including injury prevention, nutrition labeling, tobacco reduction, obesity prevention, the use of social media in health promotion and more. Technical as well as plain language summaries are available for many systematic reviews and reviews are available
- What has worked for others and how well?
- What might the intervention cost and what is likely to be achieved through the investment?
- What are the evidence gaps?

The Clearinghouse for Military Family Readiness (Pennsylvania State University)
The Clearinghouse for Military Family Readiness is an applied research center designed to help military communities identify, implement, evaluate and improve programs to strengthen military service members and families. The Clearinghouse has reviewed currently available evidence for
more than 1,000 community-based and school-based programs
and rates them as ineffective, unclear, promising, or evidence-based. These include programs specifically implemented within the military as well as non-military programs that could be implemented in a military setting. Fact sheets summarizing the available evidence for each program are publicly available.

Where a systematic review has not been conducted or there is insufficient existing scientific evidence to conduct a systematic review, the evidence base can be developed through
program evaluation studies that use well-accepted program evaluation methods (to include non-experimental, quasi-experimental, and experimental designs).
Programs improve and thrive as they grow in evidence along a continuum from Unsupported (that is, cannot produce evidence of a relationship between program services and program outcomes; sufficient data are not available) to evidenced-based (that is, endorsed by a systematic review). Click
here to see the current Army continuum of evidence-based public health practice.
PH programs, policies, and initiatives should demonstrate a commitment to establishing, measuring, and growing their evidence base over time. This requires a
variety of evaluation studies and methods conducted in various settings and with various populations. If initial program evaluation studies reveal evidence of program, policy, or initiative effectiveness, further evaluation studies strive to enhance scientific rigor of and confidence in findings through improvements in methods that minimize threats to internal and external validity of evaluation findings.
