Aromatherapy intervention on anxiety and pain during first stage labour in nulliparous women: a systematic review and meta-analysis. Methods 2.1. ... • First stage of screening involved screening the title/abstract against the inclusion and exclusion criteria. '[38] The Cochrane Handbook also outlines the key steps for preparing a systematic review[38] and forms the basis of two sets of standards for the conduct and reporting of Cochrane Intervention Reviews (MECIR - Methodological Expectations of Cochrane Intervention Reviews). The authors concluded that while the adoption of such measures may be safe, they cannot be recommended as an effective intervention to reduce the duration of first stage of labour. A meta-analysis is a statistical analysis that combines the results of multiple quantitative studies. This review included 25 studies (involving 5218 women). Synthesizing the evidence (appraising the evidence, interpreting results, performing a qualitative and/or quantitative/meta-analysis-optional), 7. [121][122][123][124][125] A host of studies have identified weaknesses in the rigour and reproducibility of search strategies in systematic reviews. EBM Pyramid and EBM Page Generator, copyright 2006 Trustees of Dartmouth College and Yale University. The version of record as reviewed is: Jack Nunn; Steven Chang; et al. Joining a collaborative volunteer effort to help categorise and summarise healthcare evidence, Data extraction and risk of bias assessment, Translation of reviews into other languages, Swift Active Screener: a paid web application. Many of our librarians are available to provide systematic review education. Screening is done independently by two reviewers, with a third as a tiebreaker. A potent means of doing so is that of systematic reviews. Source: Undertaking Systematic Reviews of Research on Effectiveness. The method characterizes quantity and quality of literature, including by study design and other features. [36] Effectively, relevant data being extracted and 'combined' in a Cochrane intervention effect review, where a meta-analysis is possible. This method for integrates or compares findings from qualitative studies. It can also refer to a combination of review approaches such as combining quantitative with qualitative research. Screening is done independently by two reviewers, with a third as a tiebreaker. What makes a good systematic review and meta-analysis? Mapping reviews can be used to identify the need for primary or secondary research. Choose to affiliate with Temple University. See our Systematic Review Search Service for help conducting the search! A scoping review is an attempt to search for concepts by mapping the language and data which surrounds those concepts and adjusting the search method iteratively to synthesize evidence and assess the scope of an area of inquiry. Learn more here. Systematic reviews are a type of evidence synthesis which formulate research questions that are broad or narrow in scope, and identify and synthesize data that directly relate to the systematic review question. Screening is done independently by two reviewers, with a third as a tiebreaker. Most notable among international organisations is Cochrane, a group of over 37,000 specialists in healthcare who systematically review randomised trials of the effects of prevention, treatments and rehabilitation as well as health systems interventions. [53] The essential difference between a living systematic review and a conventional systematic review is the publication format. Scoping reviews are helpful when determining if it is possible or appropriate to carry out a systematic review, and are a useful method when an area of inquiry is very broad,[28] for example, exploring how the public are involved in all stages systematic reviews. '[97] The Campbell Collaboration is a sibling initiative of Cochrane, and was created in 2000 at the inaugural meeting in Philadelphia, USA, attracting 85 participants from 13 countries.[98]. The present systematic review and meta-analysis aims to summarize and critically analyse the effect of acupressure on pain reduction in first stage of labour based on randomized controlled trials (RCTs). [38], Common information sources used in searches include scholarly databases of peer-reviewed articles such as MEDLINE, Web of Science, Embase, and PubMed as well as sources of unpublished literature such as clinical trial registries and grey literature collections. 5. A rapid review speeds up the systematic review process by omitting stages of the systematic review making it less rigorous. 4. [8] Several specialized PRISMA guideline extensions have been developed to support particular types of studies or aspects of the review process, including PRISMA-P for review protocols and PRISMA-ScR for scoping reviews. Screening is done in two phases. [112][113][114] Eligibility criteria must be justifiable and not arbitrary (for example, the date range searched) as this may affect the perceived quality of the review.[115][116]. For qualitative reviews PICo is 'Population or Problem', 'Interest' and 'Context'. [14][15][16] Several reporting guidelines exist to standardise reporting about how systematic reviews are conducted. 1.Define research questions (PICO) 2.Outline eligibility criteria, define 'subjects' and type of study 3.Comprehensively search the literature in more than one database, … The main question addresse d here is: Does encouraging wome n to adopt an upright position [75], The Cochrane Library is owned by Cochrane. [40], To be systematic, searchers must use a combination of search skills and tools such as database subject headings, keyword searching, Boolean operators, proximity searching, while attempting to balance the sensitivity (systematicity) and precision (accuracy).

The CEE has a journal titled Environmental Evidence which publishes systematic reviews, review protocols and systematic maps on impacts of human activity and the effectiveness of management interventions. A key step in the process of systematic review is citation screening, which involves manual review of study report titles and abstracts to identify potentially eligible articles for inclusion in the review [ 3 ]. Moller AM, Myles PS. Create a table of study results and prepare a forest plot to demonstrate the relative … The Cochrane Library also contains the Cochrane Central Register of Controlled Trials (CENTRAL) which is a database of reports of randomized and quasi-randomized controlled trials. A systematic search for data, using a repeatable method. It was originally published by Update Software and now published by the share-holder owned publisher John Wiley & Sons, Ltd. as part of Wiley Online Library. [56] Critical appraisal and synthesis of research findings in a systematic way emerged in 1975 under the term 'meta analysis'. A ‘systematic review’, or ‘overview’, has formally been defined as ‘a scientific tool which can be used to summarize, appraise, and communicate the results and implications of otherwise unmanageable quantities of research’. Questioning (Define a narrow question, may use PICO)  Is your review question a complex intervention? He used a meta-analytic approach to aggregate the outcomes of multiple clinical studies. (2020). (9 November 2020), "What are Systematic Reviews?" ", "Poor reporting and inadequate searches were apparent in systematic reviews of adverse effects", "PRISMA-S PRISMA Search Reporting Extension", "Preferred Reporting Items for Systematic reviews and Meta-Analysis Search Extension (PRISMA-S) 2019: Explanation and Elaboration", "AMSTAR 2: a critical appraisal tool for systematic reviews that include randomised or non-randomised studies of healthcare interventions, or both", "Development of AMSTAR: a measurement tool to assess the methodological quality of systematic reviews", "AMSTAR is a reliable and valid measurement tool to assess the methodological quality of systematic reviews", "ROBIS: A new tool to assess risk of bias in systematic reviews was developed", Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement, PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and explanation. Multiple authors may improve the 'validity' of the data by potentially reducing individual bias. An understanding of systematic reviews and how to implement them in practice is highly recommended for professionals involved in the delivery of health care, public health and public policy. [119] For example, in the past 10 years 8.7 million patients have taken part in trials that have not published results. There are 3.66 billion people around the world who have access to the Library through national licences (national licences cost £1.5 billion[76]) or free provision for populations in low- and middle-income countries eligible under the WHO's HINARI initiative. Here is a helpful article about review types. A tool to select the appropriate reporting guideline for your review. When appropriate, they also include the results of other types of research. [4] Systematic reviews may examine clinical tests, public health interventions, environmental interventions,[5] social interventions, adverse effects, qualitative evidence syntheses, methodological reviews, policy reviews, and economic evaluations.[6][7]. The 'AllTrials' campaign highlights that around half of clinical trials have never reported results and works to improve reporting. [74] The Cochrane Library is also available in Spanish. [106] A 2003 study suggested that extending searches beyond major databases, perhaps into grey literature, would increase the effectiveness of reviews.[107]. The main question addressed here is: Does encouraging women to adopt an upright position or to ambulate during the first stage of labor … While many systematic reviews are based on an explicit quantitative meta-analysis of available data, there are also qualitative reviews and other types of mixed-methods reviews which adhere to standards for gathering, analyzing and reporting evidence. The first phase is screening titles/abstracts, the second phase is screening full texts. [88] In addition, Cochrane has created a short video What are Systematic Reviews which explains in plain English how they work and what they are used for. The development of inclusion/exclusion criteria is discussed, and steps in the study selection process are followed from initial evaluation to the final acceptance of studies for systematic review. Scoring levels are sometimes used to rate the quality of the evidence depending on the methodology used, although this is discouraged by the Cochrane Library. [101] Such economic evidence is crucial for health technology assessment processes.

All Rights Reserved. A systematic review is a rigorous review of existing literature that addresses a clearly formulated question. The authors argue that systematic review is Each included study may be assigned an objective assessment of methodological quality, preferably by using methods conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement,[18] or the high-quality standards of Cochrane. There are over 30 types of systematic review and the Table 1 below summarises some of these, but it is not exhaustive. [117] This lack of reporting has extremely serious implications for research, including systematic reviews, as it is only possible to synthesize data of published studies. Conclusion: It is recommended that aromatherapy could be applied as a complementary therapy for reducing anxiety during the first stage of labor, but methodologically rigorous studies should be conducted in this area. Or you may reach the Team Lead, Stephanie Roth: Email, https://guides.temple.edu/systematicreviews. As a scoping review should be systematically conducted and reported (with a transparent and repeatable method), some academic publishers categorize them as a kind of 'systematic review', which may cause confusion. Reporting guidelines for reviews of Interventions. [41][42][43][44][45], Relevant data are 'extracted' from the data sources according to the review method. For this reason, it was decided to carry out a systematic review with the objective of assessing the effect of adopting the upright position or ambulating during the first stage of labor on selected obstetrical and perinatal outcomes. Often policy makers require a short deadline and a systematic review for synthesizing the evidence is not practical. This review evaluated the effectiveness of keeping an upright position or ambulating during the first stage of labour. [2] Systematic reviews are often designed to provide an exhaustive summary of current evidence relevant to a research question. The rapid growth of systematic reviews in recent years has been accompanied by the attendant issue of poor compliance with guidelines, particularly in areas such as declaration of registered study protocols, funding source declaration, risk of bias data, issues resulting from data abstraction, and description of clear study objectives. Due to the different nature of research fields outside of the natural sciences, the aforementioned methodological steps cannot easily be applied in all areas of business research. [37] Clinical reviews of quantitative data are often structured using the acronym PICO, which stands for 'Population or Problem', 'Intervention or Exposure', 'Comparison' and 'Outcome', with other variations existing for other kinds of research. KEY WORDS: study selection criteria, study quality grading, study evaluation, inclusion/exclusion criteria, [14], Developments in systematic reviews during the 21st century included realist reviews and the meta-narrative approach, both of which addressed problems of variation in methods and heterogeneity existing on some subjects.[21][22]. [111] Some website have described retractions of systematic reviews and published reports of studies included in published systematic reviews. Can be used for a variety of disciplines and review types. [86], Cochrane has produced many learning resources to help people understand what systematic reviews are, and how to do them. [47] The 'Systematic Review Toolbox' is a community driven, web-based catalogue of tools, to help reviewers chose appropriate tools for reviews. Managing & reporting (all methods are transparent and reproducible). [1] While some people might associate 'systematic review' with 'meta-analysis', there are multiple kinds of review which can be defined as 'systematic' which do not involve a meta-analysis. Methods: This is a systematic review of the effect of maternal position during the first stage of labor. A mapping review maps existing literature and categorizes data. Managing & reporting (all methods are transparent and reproducible), 6. [46], This stage involves assessing the eligibility of data for inclusion in the review, by judging it against criteria identified at the first stage. Gathering your team (Minimum of two reviewers with a third to serve as a tiebreaker). GRADE (Grading of Recommendations, Assessment, Development and Evaluations) is a transparent framework for developing and presenting summaries of evidence and is used to grade the quality of evidence. [63], There are several types of Cochrane Review, including:[64][65][66][67]. 2016. Such visualisations may have advantages over other types when reviewing complex interventions. Mixed studies review/mixed methods review. Guidance for authors when choosing between a systematic or scoping review approach", "PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and Explanation", "Animated Storyboard: What Are Systematic Reviews? [91][92][93][94] The Critical Appraisal Skills Programme (CASP) provides free learning resources to support people to appraise research critically, including a checklist which contains 10 questions to 'help you make sense of a systematic review'. Systematic review – a method for nursing research This article by Arja Holopainen, Tuovi Hakulinen-Viitanen and Kerttu Tossavainen explains the five stages of the systematic review process and describes how this method was applied to an analysis of studies dealing with nurse ‘teacherhood’. ususally based on systematic reviews. Subsequent articles covered devising a review question and a search strategy and appraising and extracting data from studies found in the search. When appropriate, some systematic reviews include a meta-analysis, which uses statistical methods to combine data from multiple sources. March 2001. [11][12][13], The EPPI-Centre, Cochrane and the Joanna Briggs Institute have all been influential in developing methods for combining both qualitative and quantitative research in systematic reviews. [54], A 1904 British Medical Journal paper by Karl Pearson collated data from several studies in the UK, India and South Africa of typhoid inoculation. The goal can be to assess how much data or evidence is available regarding a certain area of interest. Reporting guidelines for observational reviews of cohort, case-control or cross-sectional studies. PROSPERO -registry for medical/health systematic reviews, SYREAF-systematic reviews for animals and food, Joanna Briggs Institute Systematic Review Register, Inclusive Systematic Review Registration Form. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement[17] suggests a standardized way to ensure a transparent and complete reporting of systematic reviews, and is now required for this kind of research by more than 170 medical journals worldwide. Such reporting guidelines are not quality assessment or appraisal tools. [36] The search strategy should be designed to retrieve literature that matches the protocol's specified inclusion and exclusion criteria. Choosing a Review Type: This guide explains other comprehensive literature reviews of similar methodology to the systematic review. [59] Inspired by his own personal experiences as a senior medical officer in prisoner of war camps, Archie Cochrane worked to improve how the scientific method was used in medical evidence, writing in 1971: 'the general scientific problem with which we are primarily concerned is that of testing a hypothesis that a certain treatment alters the natural history of a disease for the better'. These standards are adapted from the Cochrane MECIR standards and are for disciplines beyond medicine such as crime, justice, education, international development, methods, social welfare, disability, business knowledge translation/implementation and food security. (Meeting the Review Family: Exploring review types and associated information retrieval requirements, 2019,Sutton et al.). The two most popular measurement instruments and scoring tools for systematic review quality assessment are AMSTAR 2 (a measurement tool to assess the methodological quality of systematic reviews)[135][136][137][138] and ROBIS (Risk Of Bias In Systematic reviews); however, these are not appropriate for all systematic review types.[139]. video", "Building partnerships with the public by learning about Cochrane evidence", "Making systematic reviews work for international development research", "Environmental Evidence: Reliable evidence, informed decisions, better environment", "Epidemiology and reporting characteristics of systematic reviews", "The knowledge system underpinning healthcare is not fit for purpose and must change", "Retraction Of Scientific Papers For Fraud Or Bias Is Just The Tip Of The Iceberg", "Retraction and republication for Lancet Resp Med tracheostomy paper", "BioMed Central retracting 43 papers for fake peer review", "Search Smart: Systematic Reviews: Methodology overview", "Half of all clinical trials have never reported results", "Compliance of systematic reviews in ophthalmology with the PRISMA statement", "Adjudication rather than experience of data abstraction matters more in reducing errors in abstracting data in systematic reviews", "Reproducibility of Search Strategies Is Poor in Systematic Reviews Published in High-Impact Pediatrics, Cardiology and Surgery Journals: A Cross-Sectional Study", "Analysis of the reporting of search strategies in Cochrane systematic reviews", "Compliance of systematic reviews in veterinary journals with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) literature search reporting guidelines", "Reporting quality of search methods in systematic reviews of HIV behavioral interventions (2000-2010): are the searches clearly explained, systematic and reproducible? Most of the learning resources can be found at the 'Cochrane Training' webpage,[87] which also includes a link to the book Testing Treatments, which has been translated into many languages. Learn more here. This review includes 15 trials conducted between 1990 and 2015 (3663 women): eight involved water immersion during the first stage of labour; two during the second stage only; four during the first and second stages of labour, and one comparing early versus late immersion during the first stage of labour. How to review the evidence: Systematic identification and review of the scientific literature, Lockwood, Geum. Analyze results. Searching/Screening (Exhaustive, transparent & repeatable searching for evidence/selecting studies) Includes database, grey literature/clinical trial registry and handsearching of the literature. Some systematic reviews critically appraise research studies, and synthesize findings qualitatively or quantitatively. Produced by Jan Glover, David Izzo, Karen Odato and Lei Wang. Key references can also be yielded through additional methods such as citation searching, reference list checking (related to a search method called 'pearl growing'), manually searching information sources not indexed in the major electronic databases (sometimes called 'hand-searching'),[39] and directly contacting experts in the field. National Academies of Science, Engineering, & Medicine (Formerly Institute of Medicine (IOM)) Standards for systematic reviews. Member of Student Research Committee, Abhar School of Nursing, Zanjan University of Medical Sciences, BSc in Nursing Rapid reviews are still a systematic review, however parts of the process may be simplified or omitted in order to increase rapidity. A systematic review can be designed to provide an exhaustive summary of current literature relevant to a research question. Register a systematic review protocol, including non-medical/health topics. Planning how the review will search for relevant data from research that matches certain criteria is a decisive stage in developing a rigorous systematic review.
