Results: We analysed 49,894 sampled patients (48% positive) over a period of 10,000 weeks with 19,830 slots available. Introducing a waiting list would increase ΔNTCP gain and capacity utilisation (Figure 2), especially when comparing no waiting list to a 1-week waiting list (3.26% ΔNTCP gain and >10% gain in capacity utilisation). With a 1-week waiting list, average waiting time was only 0.19 weeks, so most patients were referred directly to proton therapy. No patient waited longer than 8 weeks, suggesting max_waitlist_time > 8 weeks does not improve outcomes.
