To determine the feasibility of police officers providing defibrillation with automated external defibrillators (AEDs) and to assess the effectiveness of this strategy in reducing time to defibrillation of victims of out-of-hospital sudden cardiac arrest.
This was a prospective, interventional cohort study with historical controls conducted in 7 suburban communities in which police usually arrived at the scene of medical emergencies before EMS personnel.
All adult patients who suffered cardiac arrest before EMS arrival and on whom EMS personnel attempted resuscitation were enrolled.
Police officers who were trained to use and equipped with AEDs during the intervention phase were dispatched simultaneously with EMS to medical emergencies.
Police were instructed to use the AED immediately on determination of pulselessness.
Outcome measures were the difference between control and intervention phases in interval from the time the call was received at dispatch to the time of first defibrillation and in rate of survival to hospital discharge for patients initially in ventricular fibrillation.
EMS personnel attempted 183 resuscitations in the control phase and 283 during the intervention ; of these, 80 (44%) and 127 (45%), respectively, involved patients with initial ventricular fibrillation rhythms.
Mean time to defibrillation decreased from 11.8±4.7 minutes in the control phase to 8.7±3.7 minutes in the intervention phase (P<. 0001). (...)
