Abstract

Objectives: Quality assessment of included studies is a crucial step in any systematic review. Review and synthesis of prediction modelling studies is a relatively new and evolving area. The QUIPS tool for prediction finding studies has been recently updated. However, a tool facilitating quality assessment for prognostic and diagnostic prediction modelling studies is needed. We are currently developing PROBAST, a tool for assessing the risk of bias and applicability of prediction modelling studies. Description: The workshop will be split into two sessions. The first session will be an overview of the development and structure of PROBAST. We have used a Delphi process, including thirty-nine experts in the field of prediction research. Feedback from the first rounds of our survey suggests that a domain-based approach similar to that implemented in QUADAS-2 will be used. The presentation will give an overview of the process, the current version of the tool (including the domains covered and signalling questions) as well as an insight into underlying discussions. In the second half of the workshop, participants will have the opportunity to discuss and pilot-test PROBAST. Feedback gathered during the workshop will contribute to the evaluation, and possible revision, of PROBAST.
