5.9.3 Overview of analyzed scenarios
Different scenarios were simulated according to chamber size, average number of
sessions per day, and average occupancy rate of the chamber. Concerning chamber size,
three scenarios are analyzed: a monoplace chamber, a six- and a 12-place chamber.
Most of the Belgian centres can be put into one of these three categories (see section
5.6). Furthermore, there are three scenarios on the average number of sessions per
day, i.e. one, two or three. Theoretically, up to four sessions could be given per day.
Currently, however, only up to two sessions are given at the Belgian centres.
Therefore, we restrict our analysis to the three proposed scenarios. Finally, four
scenarios on the occupancy rate are analyzed: 30%, 50%, 70% and 90%. These are the
approximate occupancy rates that were actually observed at Belgian hospitals (see
section 5.7.1). By combining all these scenarios, 36 outcomes are obtained (Figure 31).
However, not all of these scenarios are realistic, e.g. a chamber with 3 sessions per day
with occupancy rate of only 30%, since it would reasonable to assume that instead one
or two sessions per day would be given with a higher occupancy rate. However, for the
completeness of the exercise, no scenarios were omitted.

5.9.4 Variables with probability distribution functions
Many of the input variables in this cost analysis are estimates of costs that in reality can
be quite variable and uncertain. For some of these uncertain values we therefore
determined probability distribution functions. The following distribution functions were
applied (see Table 25).
