They provide a complete summary of the current literature relevant to a research question and can be of immense use to medical professionals.
Our goal with this paper is to conduct a narrative review of the literature about systematic reviews and outline the essential elements of a systematic review along with the limitations of such a review. It compiles published research on a topic, surveys different sources of research, and critically examines these sources [ 1 ].
A literature review may be argumentative, integrative, historical, methodological, systematic, or theoretical, and these approaches may be adopted depending upon the types of analysis in a particular study [ 2 ].
Our topic of interest in this article is to understand the different steps of conducting a systematic reading writing and systematic review of research. Systematic reviews, according to Wright, et al. A systematic review provides an unbiased assessment of these studies [ 4 ].
Such reviews emerged in the s in the field of social sciences. Systematic reviews, as well as the meta-analyses of the appropriate studies, can be the best form of evidence available to clinicians [ 3 ].
The unsystematic narrative review is more likely to include only research selected by the authors, which introduces bias and, therefore, frequently lags behind and contradicts the available evidence [ 5 ]. Epidemiologist Archie Cochrane played a vital role in formulating the methodology of the systematic review [ 6 ].
Cochrane loved to study patterns of disease and how these related to the environment. In the early s, he found that many decisions in health care were made without reliable, up-to-date evidence about the treatments used [ 6 ].
A systematic review may or may not include meta-analysis, depending on whether results from different studies can be combined to provide a meaningful conclusion.
While the systematic review has several advantages, it has several limitations which can affect the conclusion. Inadequate literature searches and heterogeneous studies can lead to false conclusions.
Similarly, the quality of assessment is an important step in systematic reviews, and it can lead to adverse consequences if not done properly. The purpose of this article is to understand the important steps involved in conducting a systematic review of all kinds of clinical studies.
We conducted a narrative review of the literature about systematic reviews with a special focus on articles that discuss conducting reviews of randomized controlled trials. We discuss key guidelines and important terminologies and present the advantages and limitations of systematic reviews.
Review Narrative reviews are a discussion of important topics on a theoretical point of view, and they are considered an important educational tool in continuing medical education [ 9 ]. Narrative reviews take a less formal approach than systematic reviews in that narrative reviews do not require the presentation of the more rigorous aspects characteristic of a systematic review such as reporting methodology, search terms, databases used, and inclusion and exclusion criteria [ 9 ].
With this in mind, our narrative review will give a detailed explanation of the important steps of a systematic review. Preferred reporting items for systematic review and meta-analysis protocols PRISMA-P checklist Systematic reviews are conducted based on predefined criteria and protocol.
It also identifies a plan for documenting important protocol amendments, registry names, registration numbers, financial disclosures, and other support services [ 10 ]. Research question Writing a research question is the first step in conducting a systematic review and is of paramount importance as it outlines both the need and validity of systematic reviews Nguyen, et al.
It also increases the efficiency of the review by limiting the time and cost of identifying and obtaining relevant literature [ 11 ]. The research question should summarize the main objective of a systematic review. Try to avoid research questions that are too narrow or broad—they can lead to the selection of only a few studies and the ability to generalize results to any other populations may be limited.
It helps to formulate a research question related to prognosis, diagnosis, and therapies [ 12 ]. A year-old white woman visited her psychiatrist with a diagnosis of major depressive disorder. She was prescribed fluoxetine, which she feels has been helpful.
However, she experienced some unpleasant side effects of nausea and abdominal discomfort. She has recently been told by a friend about the use of St.
Formulating research questions, unpublished data. In the above-mentioned scenario, the sample population is a year-old female with major depressive disorder; the intervention is St.
In order to see the outcome of both efficacy and safety, we will compare the efficacy and safety of both St.Sep 01, · Systematic review is typically viewed in the health sciences as the most objective--that is, rigorous, transparent, and reproducible--method for summarizing the results of research.

Title. Reading, writing and systematic review. Aim. This paper offers a discussion of the reading and writing practices that define systematic review. Background.
Although increasingly popular, systematic review has engendered a critique of the claims made for it as a more objective method for summing up research findings than other kinds of reviews. Sep 12, · A systematic review is often used to analyze current medical research landscape or scope and to identify new research areas.
Systematic reviews are used as the basis for developing clinical guidelines and informed clinical decisions.
