The purpose of this article is to use System Dynamics approaches for early design decision support. Telehealth is proposed in many articles as one of the possibilities to answer the challenges of keeping and reinforcing the goodness and fairness of the healthcare systems. But very few studies focus on predicting telehealth integration in the current healthcare system. The model proposed in this paper simulates several scenarios of telehealth integration in order to reduce healthcare cost and save valuable medical time. It also highlights the main factors that have the most influence on the results and provides help for healthcare managers to choose between different strategies and healthcare policies.
