Have you ever wondered what goes into getting pharmaceuticals and medical devices and diagnostics to market? Patient access to these products is not as simple as going to your doctor and demonstrating a need. Even after demonstrating safety and efficacy in clinical trials, access may be limited by the primary payer (typically insurance in the US) for a variety of reasons. Decision-analytic models provide a framework for compiling clinical and economic evidence in a systematic fashion which enables the demonstration and communication of a product’s value which can be assess by healthcare decision makers. In this presentation, we will review the market access hurdles for these types of products and present examples of real-world case studies using decision analytic modeling methods to solve problems in the pharmaceutical industry.
