The health technology assessment (HTA) process takes time, but how much delay in market access should you expect? The time it takes for an HTA agency to issue a reimbursement decision can be a major factor in the overall market access timeline. While HTA agencies publish timelines to set an expectation, those timelines are not always adhered to and decisions that take longer slow down speed to market. This can result in significant business repercussions for the manufacturer including decreased ability to gain market share and increase in time to revenue generation. So, when formulating a market access strategy, an understanding of the observed time for decision versus the published timelines can help to plan and set appropriate expectations. We also want to identify other important factors of market access that take place after a decision is issued and have the potential to affect market access.
