Modelling treatment uptake scenarios
Dear TP modellers,
I have already developed a cost-effectiveness model and would like to also conduct a Budget Impact Analysis in TreeAge Pro comparing a new treatment to the standard of care. I want to incorporate different uptake (market share) scenarios into the model. Specifically, I want total costs to reflect a weighted mix of treatments (e.g. 10% new treatment and 90% curretm standard, or 60% vs 40%), but I am unsure how to implement this correctly.
I also want uptake to vary over time, following a diffusion pattern: 10% in year 1, 25% in year 2, 50% in year 3, and 60% thereafter. My model uses 6-month cycles, so I am unsure how best to translate these yearly uptake rates into cycle-specific probabilities and implement them dynamically (e.g. via functions or tables).
I would appreciate any guidance on the best way to structure this in TreeAge Pro to correctly reflect both market share weighting and time-varying uptake without reassigning patients after model entry.
Thank you very much!
Zey

There is a Budget Impact example in our help files.
https://www.treeage.com/help/Content/35-Budget-Impact-Analysis/0-Intro-Budget-Impact-Analysis.htm
This includes how to export the annual cost data from your TreeAge model as well as an Excel template for applying the changes with uptake over several years.
When using the Budget Impact export process...
since you have a 6 month cycle, you will want to export annual data for every 2 cycles.
Then you can use the exported data with the Excel template to apply those costs at a population level.
Sincerely,
Andrew
Thanks, Andrew! Does this mean that I cannot implement the uptake scenarios in the model structure? I would have to calculate this after exporting the cost data to Excel. Is this correct?
The TreeAge model just exports the costs by year. The population counts and uptake go into the Excel document.
