Below, you will find a sample of four popular quality assessment tools and some basic information about each. . What the quality assessment or risk of bias stage of the review entails Existing tools for assessing the quality of human observational studies examining effects of exposures differ in their content, reliability and usability (7-9). Traditionally, evidence-based practice has been about using systematic reviews of randomised controlled trials (RCTs) to inform the use of interventions.10 However, other types/designs of research studies are becoming increasingly important in evidence-based practice, such as diagnostic testing, risk factors for disease and prevalence studies,10 hence systematic reviews in this area have become necessary.

For example, if one item in the inclusion criteria of your systematic review is to only include randomized controlled trials (RCTs), then you need to pick a quality assessment tool specifically designed for RCTs (for example, the Cochrane Risk of Bias tool). A longitudinal study is a type of correlational research study that involves looking at variables over an extended period of time. Objectives To evaluate the risk of bias tool, introduced by the Cochrane Collaboration for assessing the internal validity of randomised trials, for inter-rater agreement, concurrent validity compared with the Jadad scale and Schulz approach to allocation concealment, and the relation between risk of bias and effect estimates. It has been adapted and updated from the former Health Evidence Bulletins Wales (HEBW) checklist (http://www.cardiff.ac.uk/insrv/libraries/sure/doc/Project%20Methodology%205.pdf)with reference to the NICE Public Health Methods Manual (2012) and previous versions of the Critical Appraisal Skills Programme (CASP) checklists, with reference to the CONSORT statement. Data were collected from 51 483 participants in Jiangxi province using the multistage stratified random cluster sampling method. The Newcastle-Ottawa Scale (NOS) was selected for cohort studies, and two ROB tools were selected for cross-sectional studies, namely the Agency for Healthcare Research and Quality (AHRQ), and the Effective Public Health Practice Project (EPHPP).

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. However, it has been debated that quality numerical scales can be problematic as the outputs from assessment checklists are not linear and as such are difficult to sum up or weight making them unpredictable at assessing study quality.39 ,42 ,43 The AXIS tool has the benefit of providing the user the opportunity to assess each individual aspect of study design to give an overall assessment of the quality of the study.

This is because when reading any type of evidence, being critical of all aspects of the study design, execution and reporting is vital for assessing its quality before being applied to practice.13 Systematic reviews have been used to develop guidelines and to answer important questions for evidence-based practice3 ,4 and CA to assess the quality of studies that have been included is a crucial part of this process.5 Teaching CA has become an important part of the curriculum in medical schools and plays a central role in the interpretation and dissemination of research for evidence-based practice.69. A detailed explanatory document was also developed with the tool, giving expanded explanation of each question and providing simple interpretations and examples of the epidemiological concepts being examined in each question to aid non-expert users. The ROBINS-I is a tool developed to assess risk of bias in the results of non-randomized studies that compare health effects of two or more interventions.

The purpose of the Delphi panel was to reach consensus on what components should be present in the CA tool and aid the development of the help text. The tool was used in the analysis of CSSs for a published systematic review.30 The tool was also trialled in a journal club and percentage agreement analysis was carried out and used to develop the tool further. , Were there enough subjects in the study to establish that the findings did not occur by chance?
