Hello! Your question is quite relevant in our field. For our pharmaceutical firm, we have been looking for a long time for a company that could develop a budget impact model. You yourself, as healthcare workers, understand how many nuances you need to take into account when building it: epidemiology, administration costs and the purchase of necessary materials and equipment, the effect of treatment, the cost and tariffs for healthcare, etc. The guys from this company Budget Impact Model - Developing For Pharma and Medtech Companies | Digital Health Outcomes coped with the task very competently and efficiently. Their model is accurate and working, and it also quickly changes after changing the set parameters. I recommend that you pay attention to them.
