Decision models are becoming more and more complex in order to better represent the underlying clinical conditions and to provide more and better insight to decision makers. New methodological techniques around decision modeling are being developed which rely heavily on statistical and mathematical techniques (e.g. model calibration, value of information, evidence synthesis). Current commercially available software can be limiting as they sometimes provide limited flexibility in embedding such statistical techniques within a decision model framework.

R is an open-source software that provides a flexible environment where advanced statistical analyses can be combined with decision models of varying complexity within the same framework and the results can be presented in publication ready tabular and graphical forms. The fact that R is freely available also improves model transparency and reproducibility.

The Child Health Evaluative Sciences (CHES) department of the Hospital for Sick Children and the THETA collaborative will be providing a 3-day workshop on decision modeling using R April 4th to 6th, 2018 at the Peter Gilgan Centre for Research and Learning, Toronto, Canada. Petros Pechlivanoglou PhD, a scientist at CHES together with guest instructors Hawre Jalal PhD from University of Pittsburg and Fernando Alarid Escudero PhD from University of Minnesota will guide participants on building probabilistic decision trees, Markov models and microsimulations, creating publication-quality tabular and graphical output and will provide a basic introduction to value of information methods and model calibration using R.

*Please note that you may register to attend in-person or by webinar

Participant Experience

Participants will be expected to have some experience with decision modeling and to be able to grasp basic concepts of economic evaluation. Participants are also expected to be familiar with R. For those with no or little experience in R, we will be providing an extra one-day "Introduction to R for decision modellers" on Tuesday, April 3rd, 2018.  

Should you wish to register for this day, there is an option to do on this site as you register for the full course.
