Diagnostic studies: methods and critical appraisal (22/09/17)

The 'Introduction to diagnostic test accuracy studies' workshop is an intensive half-day course designed for clinicians, researchers, health professionals and students who want to understand and critically appraise diagnostic accuracy studies.

Delivered through presentations and interactive examples, the workshop will take participants through different types of diagnostic study designs, measures of diagnostic accuracy and the process of critical appraisal, including an extensive risk of bias assessment.

What will you learn?

The workshop will cover the following areas:

  • An introduction to diagnostic accuracy studies
  • Characteristics of different diagnostic study designs
  • A summary of how diagnostic studies differ from prognostic risk factor and prognostic risk tool studies
  • Measures of diagnostic accuracy, such as sensitivity, specificity, positive and negative predictive value and receiver operating characteristic (ROC)/area under the curve (AUC)
  • Assessment of the risk of bias of published diagnostic accuracy studies
  • An introduction to test-and-treat trials (‘diagnostic RCTs’)

Interactive examples will help participants strengthen new skills and put them into practice.

Dates and booking details

Time: 13:00-16:30. Please note that the times may change.

Aims

By the end of this course participants will be able to:

  • understand the principles of diagnostic test accuracy studies
  • identify the strengths and weaknesses of different diagnostic accuracy study designs
  • appraise study outcomes and judge the quality of study methodology
  • be familiar with measures of diagnostic accuracy, such as sensitivity, specificity, positive and negative predictive value and receiver operating characteristic (ROC)/area under the curve (AUC)
  • understand the difference between diagnostic test accuracy studies, test-and-treat studies, and prognostic studies

The course is aimed at:

  • all levels and grades of doctor
  • medical students
  • nurses and midwives
  • pharmacists
  • allied health professionals
  • researchers
