Table 6 Simulation results for hotspots across multiple disease groups and across a subgroup with no aggregate change

From: Detecting and diagnosing hotspots for the enhanced management of hospital emergency departments in Queensland, Australia

Hotspot Number found by hotspot peak Number found by hotspot end
Univariate control chart Surveillance tree Univariate control chart Surveillance tree
a. Subgroup of All Cases 407 634 725 968
b. Subgroup of Flu Cases with ceiling 39 943 70 1000
  1. The performance results for each method over the 1000 simulations for two hotspots: one over the subgroup of cases aged 2-12 and with departure status admitted across all 3 disease groups and the other over the same subgroup in only Flu cases but with a corresponding decrease in other Flu cases.
