A new updated edition of the FRCEM Final Critical Appraisal. This 2020 edition of the revision material has been updated to include new and revised guidelines, correct typographical errors, and reference all chapters as recommended by readers. It replaces the 2019 edition. This small compilation provides aspiring candidates with a glossary of medical terms used in evidence-based medicine, a step-by-step guide to critically appraising articles published in medical journals, and guidelines for searching reports. Critical appraisal aims to help health professionals read research studies objectively by identifying valid and irrelevant points, a report's strengths and weaknesses, and its benefits and limitations. Critical reading of research reports improves the clinician's understanding of the research process. Doctors who conduct their research will ultimately benefit from strengthening their critical appraisal skills by helping them to assess their research projects and improve their skills at all stages of the research process, from project design to writing the final report. Readers are guided through the processes and given information on the factors that can influence the quality of the literature search and the research articles found. Exercises and past exams are included to deepen understanding of the text.
