Patients were divided into two groups. Group 1 consisted of patients transferred from facilities where CTP (using automated RAPID software) was routinely performed and group 2 consisted of patients transferred from facilities that did not perform perfusion imaging.Results We identified a total of 132 patients, all of whom were transferred to our center, from April 2014 to April 2017. There were no differences in baseline characteristics between the two groups. A total of 34 patients were transferred from a facility after CTP (group 1) and 98 were transferred from a facility with no CTP (group 2). Door to puncture time was significantly shorter for patients in group 1 compared with those in group 2 (median 12 (IQR 8–16) min and 48.5 (32.8–71.8) min, respectively; P<0.001). Despite obtaining additional pre-transfer imaging in group 1, there was no difference in door in and door out times at the referring facilities compared with group 2.Conclusions We found that triaging from a primary stroke center after CTP RAPID was feasible and significantly reduced the door to puncture time without any significant delay in the transfer process.
