Summary: A critical appraisal tool that includes the criteria appropriate for criticizing cross-sectional study design developed through a Delphi survey of 15 academics. of General Practice, University of Glasgow, UK, http://cobe.paginas.ufsc.br/files/2014/10/MINORS.pdf. It was the view of the Delphi group that the assessment as to whether the published findings of a study are credible and reliable should relate to the aims, methods and analysis of what is reported and not on the interpretation (eg, discussion and conclusion) of the study. If an important aspect of a study is not in the manuscript, it is unclear to the reader whether it was performed, and not reported, or not performed at all. Two authors independently assessed the quality of the studies. Were the groups comparable? During round 1 (undertaken in February 2013) of the Delphi process, 20 components reached consensus, 13 components were assessed to require modification and it was deemed appropriate to remove 4 components from the tool. Two contacts felt they were not suitably qualified for the Delphi panel (n=2); one was retired and the other was a lecturer with research and clinical duties. With the reduction in the number of questions and modification of the wording, comments in round 2 reflected the positive nature to the usability of the tool.I like the fact that it is quite simplenot too overloaded with methodological questions. It is important to note that a well-reported study may be of poor quality and conversely a poorly reported study could be a well-conducted study.33 ,34 It is also apparent that if a study is poorly reported, it can be difficult to assess the quality of the study. You can opt to manually customize the quality assessment template anduse a different tool better suited to your review. Critical appraisal aims to identify potential threats to the validity of the research findings from the literature and provide consumers of research evidence the opportunity to make informed decisions about the quality of research evidence. What is the measure? Int J Environ Res Public Health. A cross-sectional study assesses risk factors and the outcome at the same moment in time. A cross-sectional study is conducted over a specified period of time. In case of disagreement, another author was consulted, and discussions were held until a consensus was reached. Objectives: [9] Critical appraisal may also be an integral part of formalized approaches to turn evidence into recommendations for practice such as GRADE. OARSI recommendations for the management of hip and knee osteoarthritis, part I: critical appraisal of existing treatment guidelines and systematic review of current research evidence.

Higgins JP, Green S. Cochrane handbook for systematic reviews of interventions. The comments suggested that a long questionnaire would lead to the tool being cumbersome and difficult to use, and for this reason, efforts were made to develop a much more concise tool. Prior to conducting the Delphi process, it was agreed that consensus for inclusion of each component in the tool would be set at 80%.31 ,32 This meant that the Delphi process would continue until at least 80% of the panel agreed a component should be included in the final tool. A CA tool to assess the quality and risk of bias in CSSs (AXIS), along with supporting help text, was successfully developed by an expert panel using Delphi methodology.

The components of the AXIS tool are based on a combination of evidence, epidemiological processes, experience of the researchers and Delphi participants. The process was repeated, with a new draft of the CA tool circulated each time based on the findings and consensus of the previous round, until 80% consensus on all components of the tool was achieved. One of the key items raised in comments from the experts was assessing quality of design versus quality of reporting.

After 3 rounds of the Delphi process, the Appraisal tool for Cross-Sectional Studies (AXIS tool) was developed by consensus and consisted of 20 components. The basis of a cross sectional study design is that a sample, or census, of subjects is obtained from the target population and the presence or the absence of the outcome is ascertained at a certain point.11 Various reporting guidelines are available for the creation of scientific manuscripts involving observational studies which provide guidance for authors reporting their findings. Using this type of survey is a fast, easy way for researchers . Federal government websites often end in .gov or .mil. To ensure that the tool was developed to a high standard, a high level of consensus was required in order for the questions to be retained.31 ,32 ,39 There was a high level of consensus between veterinary and medical groups in this study, which adds to the rigour of the tool but also demonstrates how both healthcare areas can cooperate effectively to produce excellent outcomes. 0000120034 00000 n Two contacts did not respond to the emails; these were both lecturers with research duties.

Critical appraisal (or quality assessment) in evidence based medicine, is the use of explicit, transparent methods to assess the data in published research, applying the rules of evidence to factors such as internal validity, adherence to reporting standards, conclusions, generalizability and risk-of-bias. List is too long at present and contains too many things that are general to all scientific studies. The use of a multidisciplinary panel with experience in epidemiology and EBM limits the effect of using a non-representative sample, and the use of the Delphi tool is well recognised for developing consensus in healthcare science.38 The selection of a Delphi group is very important as it effects the results of the process.31 As CSSs are used extensively in human and veterinary research, it was appropriate to use expertise from both of these fields. If consensus was 50%, components were removed from the tool. , Were subjects randomly allocated?
