“Exclusive-Use Scenario. In this scenario, the overall wait time probability at angioINR was reduced compared to baseline (red line in Figure 2B compared to Figure 2A). This represents a decrease in ECR patient wait time for angioINR by an average of 6 min.” Huang et al. (2019)

“Two angioINRs Scenario. This scenario simulates the effect a facility upgrade to two biplane angiographic suites, but without additional staff changes. The wait time probability at angioINR was reduced compared to baseline (Figure 2C). The reduction represents an average of 4 min less in queue for angioINR.” Huang et al. (2019)

“Extended Schedule Scenario. The wait time probability at angioINR in the exclusive- use scenario was further reduced by extended work hours (Figure 3B). In contrast, work extension did not affect baseline or the 2 angioINRs scenario (Figures 3A,C). For the baseline scenario, 1 and 2 h of extra work resulted in an average wait time of 1.7 and 0.9 min reduction, respectively. For the 2 angioINRs scenario, 1 and 2 h of extra work resulted in an average wait time gain of 1 and 0.3 min, respectively.” Huang et al. (2019)
