Figure 6.

Impact of an optimised system. Map shows Ireland broken into 139 regions with geographic centres plotted. Door to needle time is reduced to 30 min, time from alteplase administration to departure for the endovascular thrombectomy (EVT) centre is reduced to 30 min, door to groin puncture time is reduced to 60 min in the mothership scenario and remains at 10 min in the drip-and-ship scenario. Panel A displays one EVT centre; panel B shows two EVT centres. Regions are colour coded to show the method predicting the best probability of good outcome.

DIDO: door-in-door-out; DTN: door to needle; DTP: door to puncture.
