In budget impact analysis, it is usual to compare a hypothetical future scenario (i.e. the approval of a new technology) against the counterfactual (i.e. no approval of the technology).  Because it is rare for a new technology to be provided universally to all eligible patients, budget impact models usually make an assumption about the ‘uptake’ of the technology.  This is usually characterised as the proportion of patients that would receive the technology in each consecutive year after its introduction.  Often, the uptake may start slowly (with a low % of patients) and gradually increase over time.  Careful consideration should be given to whether the new technology will only to new (incident) patients, to existing (prevalent) patients or to both.
