Background

As for any healthcare intervention, medical tests require thorough evaluation. Identifying the accuracy of a test is a key step in the evaluation process. Understanding other ways in which tests affect the clinical management of patients is also important – a new test may be more acceptable to patients, easier to administer, or provide a faster diagnosis or treatment.

The accuracy of a test is a measure of how well it differentiates those with a disease or condition from those who do not. Different, sometimes complex, study designs can be used to evaluate diagnostic accuracy. Measures of accuracy are also not fixed properties of a test and may not be transferable across different populations and settings. A systematic review aims to provide an overview of currently available evidence about a test’s diagnostic accuracy. A basic understanding of study designs, potential sources of bias, and factors that might affect the applicability of a study’s findings, are essential to ensure that the included studies answer a relevant review question.

Aim

To provide an introduction to systematic reviews of diagnostic test accuracy.

Learning outcomes

In this course participants will be enabled to:

• describe the key differences between systematic reviews of interventions and systematic reviews of test accuracy
• be aware of study designs used to estimate and compare the accuracy of tests
• be aware of the sources of bias and variation that occur in test accuracy studies
• be aware of the approaches used for meta-analysis of test accuracy and interpretation of meta-analytic estimates

This workshop will not cover how to conduct a meta-analysis of test accuracy studies

Teaching strategies

The workshop will consist of a mixture of short presentations and practical exercises.
