These keywords will be used in searching databases. PICO, PICOS and SPIDER: A comparison study of specificity and sensitivity in three search tools for qualitative systematic reviews. Most process evaluation data collection occurred post-intervention undermining the ability to evaluate the process of implementation. Research questions are often devised with the use of the PICO structure: Population, Intervention (or Exposure), Control/Comparator, Outcomes. A clearly defined, focused review begins with a well-framed question. There are different types of Systematic Reviews. A proportion of these will look as though they are relevant to the review's research questions. In some cases the review question may also include the Study Design (PICOS). The PRISMA Statement consists of a 27-item checklist and a four-phase flow diagram … Note the iterative nature of the process (arrows on the left). Should previous systematic reviews and meta-analyses be included in a systematic review? A solid understanding of the systematic review process can be of benefit to nurses that carry out such reviews, and for those who make decisions based on them. Write the protocol, which includes the inclusion/exclusion and eligibility criteria. 4 or more team members are recommended. ... By promoting transparency in the process and enabling comparison of reported review findings with what was planned in the protocol PROSPERO also aims to minimise the risk of bias in systematic review. Conducting a systematic review is a complex process. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. It will focus on the practicalities, and build on the introductory modules. 1. It is important to have a record of decisions made in order to ensure reproducibility and minimize errors. You can read more about the peer-review process here. Systematic review automation technologies. people, and embrace their culture, wisdom and knowledge. Some key steps in searching for studies include: It’s important to note that the IOM recommends working “with a librarian or other information specialist trained in performing systematic reviews to plan the search strategy” (IOM Standard 3.1.1). "As well as drawing results together, synthesis should consider the strength of evidence, explore whether any observed effects are consistent across studies, and investigate possible reasons for any inconsistencies" (Centre for Reviews and Dissemination, 2009, section 1.3.5). Standard systematic reviews come in many shapes and sizes and vary between subjects. Here, data simply refers to information about or details from a study including its methods and design, participants, setting, interventions, results, etc. Identify any recent or ongoing systematic reviews. Many commissioning bodies and journals have adopted PRISMA as the required methods for reporting systematic reviews. The PRISMA Checklist gives an overview of the whole process of conducting a systematic review. Systematic reviews adhere to a strict scientific design based on pre-specified and reproducible methods. Systematic Reviews are not limited to questions about effects of interventions, they may address trends, accuracy of diagnostic tests, effectiveness of programs, etc. This PRISMA flow diagram shows the number of studies/papers remaining at each stage. P: Perspective Assessment of study quality gives an indication of the strength of the evidence provided by your review. Systematic review authors need to both identify the tool they have used for data extraction and the reasons for selecting (or adapting) it. For further details and guidance, refer to the Standards section of this guide. The steps for revision or amendment are the same as those for preparation of a new standard (see ISO/IEC Directives, Part 1, Clauses 2.3 to 2.8). This is typically the domain of clinical practice guidelines. Includes a written protocol (a reasoned plan for the entire review process). A recent review of 87 systematic reviews found that about half included a QUOROM flow diagram.133 The authors of this research recommended some important ways that reviewers can improve the use of a flow diagram when describing the flow of information throughout the review process, including a separate flow diagram for each important outcome reported.133 It attempts to uncover “all” of the evidence relevant to a question. It's a simple and useful way of documenting the study selection process and should be included in your final report. If a high quality review exists but was completed several years ago, a new review may be justified. Synthesis may be done quantitatively using statistical techniques, such as a meta-analysis, or through a narrative approach. A systematic review is a complex piece of research that aims to identify, select and synthesise all research published on a particular question or topic. Cochrane Collaboration Handbook . To be included, a study must meet all eligibility/inclusion criteria and not meet any exclusion criteria. A systematic review answers a defined research question by collecting and summarising all empirical evidence that fits pre-specified eligibility criteria. We are starting this service to help the UCSF community by clarifying the systematic review process. (see box below). Systematic reviews differ from narrative reviews in that narrative reviews tend to be mainly description and do not involve a systematic search of literature and are often based on author selection. (2012). Smaller teams are possible, three is the realistic minimum. A meta-analysis is the use of statistical methods to summarise the results of these studies. 2. Circulation: 410-706-7928.

Quantitative systematic reviews use formal statisitical techniques such as meta-analysis to perform this step. It contains resources for "writing a great research paper using reporting guidelines. NOTE: If you are considering purchasing a book, buy the 2nd edition (2017). Appraise and select suitable studies. So, having explicit criteria against which to assess studies makes the process more efficient in terms of time. You will consider the importance of systematic literature reviews for organisations and you will have the opportunity to learn about the process of identifying a research topic. "Being comprehensive means that the search strategy attempts to uncover published and unpublished, easily accessible and harder to find reports of research studies. In general, making recommendations for practice does not fall within the purview of systematic reviews. The citation databases, Web of Science and SCOPUS are useful for identifying key journals and authors, as well as tracking research and citation searching. Scoping reviews. Systematic reviews synthesise relevant research around a particular question. The stages in conducting a review are: Formulate the question - a clearly defined question will ensure that your research produces relevant results. Formulate a specific research question that is clear and focused. History of systematic reviews to inform policy (EPPI-Centre) Six reasons why it is important to be systematic (EPPI-Centre) Different Types of Systematic Reviews There are many types of systematic reviews. A standard formula for structuring the review question is PICO(S) for quantitative questions and SPIDER for qualitative questions. The Systematic Review Process Systematic reviews are considered the highest levels of evidence, but only if they are done rigorously. Systematic reviews, just like other research articles, can be … Systematic reviews are characterized by a methodical and replicable methodology and presentation. Many potential systematic review authors approach us. Explicit, reproducible search strategies and eligibility criteria are used and every effort should be made to search a variety of sources for relevant articles, including grey and unpublished literature. A systematic review uses specific procedures to locate, evaluate and synthesize the results of relevant research to address your research question. As a minimum, one researcher should extract data with a second person checking for accuracy. This explainer video from The Evidence Synthesis Academy at Brown University walks you through the basic steps. But, The Cochrane Collaboration states that "efforts should be made to identify unpublished studies." Systematic Reviews. Modiﬁcations may arise from a clearer understanding of the review question, and should not be made because of an awareness of the results of individual studies. The topic may be broad. Answers a well-defined and focused research question. PubMed). These mnemonics can be used to construct your research question and break down your search strategy. On this course you will consider the answers to this question as you explore the different types of literature review. The systematic review process. Evidence synthesis Designing the Question The design of a research question requires careful selection of language, which mirrors the intent of the research. BMC Health Services Research, 14(1), 579. doi:10.1186/s12913-014-0579-0, What authors do by Jessica Kaufman, Cochrane Consumers & Communication review Group /CC BY-SA 4.0. A systematic review usually involves more than one person in order to increase the objectivity and trustworthiness of the reviews methods and findings. PROSPERO accepts registrations for systematic reviews, rapid reviews and umbrella reviews. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flow diagram or similar chart can be useful to visualise and report the study selection process. It looks like you're using Internet Explorer 11 or older. I: Interest (The phenomena of Interest relates to a defined event, activity, experience or process) Identify your research question. For further details and guidance, refer to the Standards section of this guide. I: Intervention This process should involve at least two members of your group to help reduce bias. Identify any recent or ongoing systematic reviews. The National Academies Press (formerly IOM) standards address the entire systematic review process, from locating, screening, and selecting studies for the review, to synthesizing the findings and assessing the overall quality of the body of evidence, to producing the final review report. PROSPERO has been developed and is managed by the Centre for Reviews and Dissemination (CRD) … Include elements of systematic review process, but searching is often not as comprehensive as a systematic review and may not include quality assessments of data sources. The below handbooks provide step by step guidance for conducting a systematic review. Developing a literature search strategy is a key part of the systematic review process, and the conclusions reached in a systematic review will depend on the quality of the evidence retrieved by the literature search. The module will use a problem-based learning approach in which each participant brings a specific topic for a systematic review to discuss, justify and revise during the module. Search the Grey Literature, such as conference proceedings, theses, reports and unpublished literature. Systematic reviews and meta-analyses are not the same. This may require preliminary searching (scoping) to see what evidence is already available and whether a systematic review has been done before. Collecting too much or too little information may be a waste of time and result in the omission of crucial data. A systematic review is a process to: determine a question; set inclusion and exclusion criteria; find and select the literature The following information is intended to be a general introduction to the process of conducting systematic reviews.
