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 TM ) aids response time by controlling traffic signals. This eight-year observational study investigated whether FAST TM implementation reduced response times and improved OHCA outcomes.
Results:The median response time significantly differed between the FAST TM -equipped and non-FAST TM -equipped groups at 327 and 381 s, respectively. The 1-Y survival rates were 7.0% in the FAST TM -equipped group and 2.8% in the non-FAST TM -equipped group. Logistic regression analysis revealed that the dispatch of a FAST TM -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 TM implementation significantly reduced ambulance response times and improved OHCA outcomes in Kanazawa city. (Word count: 231)
