Systematic
reviews are a summary of high quality, evidence based research studies that are
used to condense data on a topic into one well researched review. Systematic
reviews are used in hopes to help biased opinions analyze the different data on
a topic to better understand the evidence behind the topic. Systematic reviews
are especially helpful in healthcare research due to the revolving amount of
technology in the 20th century.

Systematic
reviews consist of multiple different components that help guide data to a
synthesized conclusion. According to, Systematic Reviews and Meta-Analyses,
there are eight steps in formulating this type of review (Uman, 2011). Some, but
not all, reviews include a meta-analysis which is a comparison of statistical
data used to obtain stronger explanation.

First and
foremost, the reviewer must develop the question with inclusion and exclusion
criteria often referred to as a ‘PICO’ question (Participants, Interventions,
Comparisons and outcomes) (Riva, Malik, Burnie, Endicott & Busse, 2012).  The reviewer must then develop a search
strategy and choose literature from a comprehensive search. The data must then
be pulled together and organized from the chosen literature. The literature
must also be evaluated to assess the quality of the data. An interpretation of the
analyzed results can then be made to help better explain the data in
quantitative or qualitative form (Uman, 2011). Lastly, an evidence based
conclusion must be drawn from the supported literature and research.

The
different literatures chosen for a systematic review are fully dissected to
find the most pertinent and relevant data for the study. These reviews are used
in the determination of the evidence primarily because it pulls together all
the data on a specific topic to allow healthcare professionals to compare and analyze
the results to make changes in healthcare. Unfortunately, health professionals
do not always have the time to read the original articles in full link to find
the evidence where systematic reviews narrow down the evidence to one article
making them more convenient for quick decision making. They allow health professionals
to stay up to date with their field of study and are also helpful when
controversy arises on a topic (Gopalakrishnan & Ganeshkumar, 2013).
