Study Notes

Critical Appraisal

Critical appraisal is the process of carefully and systematically examining research to judge its trustworthiness, value, and relevance in a particular context.
It is an essential skill for evidence-based medicine, allowing clinicians to find and use research evidence reliably and efficiently.

Critical Appraisal Process

Critical appraisal involves systematically evaluating clinical research papers to establish: • Does the study address a clearly focused question? • Did the study use valid methods to address this question? • Are the valid results of this study important?
It also involves assessing the data in published research, applying the rules of evidence, adherence to reporting standards, conclusions, generalizability, and risk-of-bias.

Critical Appraisal Skills

The Critical Appraisal Skills Program aims to help people develop the necessary skills to make sense of scientific evidence, and has produced appraisal checklists covering validity, results, and relevance.
Different research questions require different study designs, and the best design for studies evaluating the effectiveness of an intervention or treatment is a randomized controlled trial.

Critical Appraisal Tools

Systematic reviews, which collect, appraise, and combine evidence, should be used when available.
Critical appraisal checklists help to appraise the quality of the study design and (for quantitative studies) the risk of bias.
Critical appraisal tools for cross-sectional studies include the AXIS tool and JBI tools, and the JBI tool for assessing case series.

Purpose of Critical Appraisal

The purpose of critical appraisal is to determine the scientific merit of a research report and its applicability to clinical decision-making.
It helps to evaluate a study for the general purpose of understanding current information in areas of practice, or for its application to a particular patient problem.
Critical appraisal is used to frame a clinical question using the PICO format, directing a search and identifying appropriate research reports.

PICO Format

The PICO format is used to frame a clinical question, including: • Patient / Population • Intervention • Comparison • Outcome

Importance of Critical Appraisal

Critical appraisal is necessary to ensure reliable information about what might harm or help us when making healthcare decisions.
Not all research is good quality, and many studies are biased, leading to false conclusions.
Critical appraisal helps to determine whether a piece of research has been done properly and that the information it reports is reliable and trustworthy.
