摘要：

Objectives: Stroke patients are frequently transported to a comprehensive stroke center for treatment, either from a regional hospital via interhospital transfer or from the field via direct-from-scene transfer, by air or ground transportation. We sought to determine whether air or ground transport was faster in both transfer circumstances. Materials and methods: A retrospective study of patients transferred to a single comprehensive stroke center for stroke treatment was conducted. EMS and medical records were used to evaluate the time and distance of transfer and functional outcome. Results: Of the 205 transfers, 47 were interhospital transfers by air (22.9%), 68 were interhospital transfers by ground (33.2%), 40 were scene transfers by air (19.5%), and 50 were scene transfers by ground (24.4%). Ground transfers had shorter alarm to EMS departure times (30 min. vs 40 min.; p<0.0001). Air transfers had shorter EMS departure to arrival times when normalized by transfer distance indicating a faster travel velocity. Interhospital transfers by air were predicted to be faster than ground over 40 miles, and scene transfers by air were predicted to be faster than ground over 28 miles. Transfer mode had no significant effect on functional outcome when controlling for tPA, thrombectomy, and NIH Stroke Scale in this small study. Conclusions: Transfer efficiency for stroke patients depends on logistics prior to EMS arrival as well as the speed of travel. While air transport clearly results in faster travel velocity, total interhospital transfer times are faster for air transportation only when traveling more than 40 miles.
