Pre-conference Courses

Clinical prediction models are used to estimate an individual’s risk of a health-related outcome to help guide patient counselling and clinical decision making. Examples include QRISK, which is widely used in the UK during primary care consultations to estimate a person’s 10-year cardiovascular disease risk. 

In this course, participants will be provided with an introduction to clinical prediction models and how to improve standards, which currently are often poor. A pathway will be described from model development to model evaluation and impact assessment.  

We then focus primarily on sample size calculations for model development and evaluation. We introduce the theory behind existing and emerging approaches, and showcase the pmsampsize, pmstabilityss and pmvalsampsize packages in Stata and R that implement them. Hands-on practicals are included, and participants will be supported by a dedicated and experienced faculty. Participants are required to bring their own laptop with either R or Stata installed.

Faculty includes: Dr Joie Ensor, Dr Kym Snell, Dr Lucy Archer, Dr Becky Whittle, Dr Amardeep Legha and Prof Richard Riley from University of Birmingham

Systematic reviews of prognosis studies

Prognosis studies are abundant in this era of personalized and precision medicine, which all has to do with prognosis research. Hence, systematic reviews of prognosis studies are increasingly required and conducted. 

This workshop will introduce participants to the different types of prognosis research and explain the differences between prognosis, diagnosis and intervention studies. We then provide explicit guidance how to define a proper review question using the PICOTS format, to design a review protocol, to search the literature, to extract the data using the CHARMS checklist, to assess the risk of bias in the primary studies using PROBAST+AI and QUIPS, and finally to conduct a meta-analysis of the retrieved data and test for heterogeneity across studies. We will illustrate all this using many empirical examples, and frequently apply small group practicals and discussions. 

After this workshop, participants have a good overview of the essentials of prognosis research and systematic reviews of such studies.

Faculty includes: Dr Anneke Damen, Prof Karel Moons from UMC Utrecht

Either course can be selected during conference registration and are only open to those registering for the conference. Please note that only one course should be selected as the two options will run in parallel. Limited places available.
