概要:

Purposes: Ambulance response time is a major factor associated with survival in out-of-hospital cardiac arrests (OHCAs); the fast emergency vehicle pre-emption system (FAST™) aids response time by controlling traffic signals. This eight-year observational study investigated whether FAST™ implementation reduced response times and improved OHCA outcomes. Methods: Data was prospectively collected from 1161 OHCAs that were not witnessed by emergency … medical technicians from April 1, 2003, to March 31, 2011. The study took place in Kanazawa city, where ambulances without FAST™ (non-FAST™-equipped) were being progressively replaced by new FAST™-equipped ambulances. OHCA data, including the response times recorded in seconds, were collected and compared between the FAST™-equipped and non-FAST™-equipped ambulances. OHCA outcomes were subsequently compared in the subgroup of OHCAs managed by emergency medical technicians without tracheal intubation or epinephrine administration. The primary end-point of this study was one-year (1-Y) survival. Results: The median response time significantly differed between the FAST™-equipped and non-FAST™-equipped groups at 327 and 381 s, respectively. The 1-Y survival rates were 7.0% in the FAST™-equipped group and 2.8% in the non-FAST™-equipped group. Logistic regression analysis revealed that the dispatch of a FAST™-equipped ambulance was an independent factor for 1-Y survival (adjusted odds ratio = 3.077, 95% confidence interval = 1.180-9.350). Conclusions: The FAST™ implementation significantly reduced ambulance response times and improved OHCA outcomes in Kanazawa city. © 2013 Elsevier Inc. All rights reserved. 続きを見る
