Information deals with how to write a organized review. Systematic reviews have become popular during the last 20 years approximately, particularly in health and health care related areas. Systematic Books Review, sometimes known as organized reviews, are associated with evidence-based healthcare practice, the idea that medical and related healthcare disciplines should be grounded in the the majority of up-to-date and accurate research evidence.
However , they are more and more used in other locations. Systematic testimonials assess whenever possible of the available research in the area of concern. The goal is to create a rigourous and impartial review of evidence based upon clear, reproducible protocols and transparent selection methods.
Carrying out a Organized Review
A scientific review may be divided into crystal clear, logically distinctive stages:
Creating the research issue
Devising the study protocol
Undertaking the literature search
Taking out the data
Appraising the quality
The first step is to make a research problem. This stage forms a part of a larger level of devising the research process. The question needs to be clearly focussed, neither too small nor also broad. The acronym EXTREMIDAD has been created to sum up the several parts a question should take into consideration (the population or individual group studied, the treatment, treatment or test, an evaluation or substitute intervention, and the outcome with the intervention (see figure you for an example)
The research process covers the methods for looking the literature and removing and analysing the data. The methodology must be clearly defined before beginning, in order to reduce bias. Inclusion and exclusion criteria also need to be established at this stage. For example , it might be chosen to include simply published articles or blog posts, and banish studies in languages apart from English.
The literature search is the next step. Bibliographic databases including Pubmed, Medline, the Cochrane Collection and Embase (for healthcare) can be used. It can be wise to employ more than one on the web database as each a single includes a several range of periodicals. Reference lists of articles or blog posts are useful for locating new areas to investigate, just like handsearching of journals. The aim of searching the literature should be to produce an inclusive list of relevant research studies that to select the studies included in the review. This stage also involves screening process for and removing replicates. This can be performed through a computer based research management system just like EndNote.
Data extraction can be achieved using a standardised form. This links to the example of such a form: http://www.ncbi.nlm.nih.gov/books/NBK56167/. Such a form means info can also be created a databases, making future use simpler. Different types of organized review require different forms, so ensure you employ the most appropriate type.
Top quality appraisal is perhaps the most central step, and a number of check-lists which have been created to help with this process. This kind of links into a simple and easy to comprehend example: http://www.gla.ac.uk/media/media_64047_en.pdf. It should be considered, however , that different check-lists can produce very different results.
On such basis as quality evaluation, studies happen to be rejected and accepted. Data analysis may be the next level. A simple type of data examination is to descriptively evaluate the research, summarising these in table formatting. Such dining tables typically are the population studied, interventions and outcomes. Method and potential bias may additionally be outlined. Metaanalysis may additionally be completed.
The the desired info is then interpreted. Strengths and weaknesses with the studies contained in the review are believed. The findings of the research are summarised, and conclusions indicated. Recommendations for future research are often made.
Writing up a Systematic Review
Organized reviews stick to clear composition, generally from the format
It should be to the point and appropriate
The abstract ought to be clearly structured
The intro should sum up the topic and explain so why the assessment is necessary. It should end with a summary assertion of the aims
The method should adhere to clear structure, looking at inclusion/exclusion characteristics, how studies were indentified, just how studies included were taken care of, data extraction and quality assessment
The results section covers the way the data was handled (including any statistical analysis)
The results needs to be set out realistically. This section addresses the number of research found, how many ruled out, details of study range and characteristics, examine quality, and so on.
The discussion section should also become clearly ordered. It depends on a summary affirmation setting out the primary finding. The next paragraph explains limitations of studies included and of the review process. The third paragraph should cover the unfavorable and strengths of the method, while the last paragraph contexualises the leads to terms of existing expertise. The final passage sets out a conclusion and ramifications.
