  • Title: Is public access defibrillation needed in Hong Kong?
    Author: Lo CB, Wong TW, Lai KK.
    Journal: Hong Kong Med J; 2003 Apr; 9(2):113-8. PubMed ID: 12668822.
    Abstract:
    The survival rate for non-traumatic out-of-hospital cardiac arrest in Hong Kong is low (1.25%-1.6%). Despite the reduced time interval between call receipt and first defibrillatory shock to 11.12 minutes during the past decade, the time interval between collapse/recognition and first defibrillatory shock, at 14.25 minutes, is too long. Studies of out-of-hospital cardiac arrest performed in Hong Kong were reviewed to ascertain whether a public access defibrillation programme can improve survival in Hong Kong. Three delays were found in the traditional response by emergency medical service, namely in the collapse/recognise-to-call receipt, call receipt-to-vehicle stops, and vehicle stops-to-first defibrillatory shock time intervals. The first delay is related to public education, while the second and third delays are intrinsic to a dispatched response. A public access defibrillation programme employing responders at scenes of cardiac arrests can eliminate the collapse/recognise-to-call receipt and call receipt-to-vehicle stops time intervals before defibrillation. Possible sites of public access defibrillation could include the airport and other immigration points, which have a high volume of people passing through, with projected figures for out-of-hospital cardiac arrest at these sites supporting this consideration. For successful implementation of public access defibrillation, a comprehensive educational programme and coordination with the emergency medical service are required.
