Figure 4.

Impact of reducing door-in-door-out time. Map shows Ireland broken into 139 regions with geographic centres plotted. Actual median door to needle time for each centre is used, door-in-door-out time is reduced by reducing time from alteplase administration to departure for the endovascular thrombectomy (EVT) centre to 30 min, door to groin puncture time is 100 min in the mothership scenario and 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.
