Introduction:Our telestroke (TS) network instituted a regional transfer protocol (RTP) that allows for stroke patients in need of higher level of care to be pre-accepted and transferred to the nearest appropriate comprehensive stroke center (CSC). We studied the impact of the RTP on resource utilization and time metrics in patients transferred for evaluation of intra-arterial thrombectomy (IAT). Before the RTP, all potential IAT patients were transferred to one central CSC. After the RTP was initiated, the network had the capability to transfer to two additional CSCs within the same health system that are strategically located in the Houston area.Methods:We identified patients evaluated via TS in spoke emergency rooms that were subsequently transferred for IAT evaluation from 1/1/2016 to 12/31/2017 - one year prior and one year after the RTP. Baseline demographic characteristics, transfer and IAT metrics, and outcomes were compared for the two time periods.Results:Of 220 patients, 102 patients were transferred pre-RTP, and 120 were transferred to the three CSCs post-RTP. There were no significant differences in baseline characteristics, except fewer patients received tPA post-RTP (Table 1). In total, 30 patients (29%) pre-RTP and 42 patients (35%) post-RTP underwent IAT (p=0.38). Post-RTP, there was a trend toward faster travel times (median 40 vs 32 minutes, p=.07) and transfer initiation times to hub arrival times (median 109 vs 100.5 minutes, p=0.09). Door to groin puncture times were not statistically different between the two time periods. Post-RTP patients had a significantly shorter length of stay (median 6 vs 5 days, p=0.03).Conclusions:Regional transfer protocols can potentially help reduce transfer times and length of stay for stroke patients at CSCs that were initially seen by TS at community hospitals; however, larger sample size is needed to study its impact on other IAT-related metrics and clinical outcomes.
