“…3,7,12,15 Unsurprisingly, for the nonshockable rhythms the mean time from collapse to application of the AED was 10 [2][3][4][5][6][7][8][9][10][11][12][13][14][15] min. This could probably be explained by the fact that fewer OHCAs with an initial non-shockable rhythm were witnessed (54% versus 94%).…”

“…6,[9][10][11][12] Although deployment of AEDs is increasing 7,13 the application rate is poor even when trained bystanders are on scene. 5,14 These operational aspects of PAD have been less intensively studied and detailed information about the characteristics of the deployed AEDs, bystander background, and circumstances of the OHCA is scarce. These characteristics could be useful to optimize future organization of PAD programmes.…”

“…Early studies of PAD suggested that the few AEDs available were actually underused even when trained bystanders were on scene,7 17 and although distribution of AEDs is increasing,8 18 19 little is known about the current availability and use of AEDs in the community. With clearly documented survival benefits of PAD programmes, it is important to understand how the early links in the chain of survival can be strengthened.…”

IntroductionPublic access defibrillation (PAD) prior to ambulance arrival is a key determinant of survival from out-of-hospital (OOH) cardiac arrest. Implementation of PAD has been underway in the UK for the past 12 years, and its importance in strengthening the chain of survival has been recognised in the government's recent ‘Cardiovascular Disease Outcomes Strategy’. The extent of use of PAD in OOH cardiac arrests in the UK is unknown. We surveyed all OOH cardiac arrests in Hampshire over a 12-month period to ascertain the availability and effective use of PAD.MethodsA retrospective review of all patients with OOH cardiac arrest attended by South Central Ambulance Service (SCAS) in Hampshire during a 1-year period (1 September 2011 to 31 August 2012) was undertaken. Emergency calls were reviewed to establish the known presence of a PAD. Additionally, a review of all known PAD locations in Hampshire was undertaken, together with a survey of public areas where a PAD may be expected to be located.ResultsThe current population of Hampshire is estimated to be 1.76 million. During the study period, 673 known PADs were located in 278 Hampshire locations. Of all calls confirmed as cardiac arrest (n=1035), the caller reported access to an automated external defibrillator (AED) on 44 occasions (4.25%), successfully retrieving and using the AED before arrival of the ambulance on only 18 occasions (1.74%).ConclusionsDespite several campaigns to raise public awareness and make PADs more available, many public areas have no recorded AED available, and in those where an AED was available it was only used in a minority of cases by members of the public before arrival of the ambulance. Overall, a PAD was only deployed successfully in 1.74% OOH cardiac arrests. This weak link in the chain of survival contributes to the poor survival rate from OOH cardiac arrest and needs strengthening.

“…During the intervention period, all 57 survivors in whom witnessed status could be confirmed were witnessed by either bystanders or EMS-crews. 2 We therefore agree with Kee and co-workers that the baseline incidence of witnessed cardiac arrest is critical to the success of a first responder defibrillation program. The incidence of witnessed cardiac arrest was very different in the SALSA study compared with the NIPAD study (70.6 vs. 33.8%).…”
