OBJECTIVE: In Japan, number of PAD case have been increasing after the governmental approval in 2004, but its detail has not been reported. Our objective is to clarify the actual situation of PAD in Hyogo prefecture, located in the mainland Japan, with 5.6 million populations.
METHODS: We retrospectively analyzed the ambulance records about bystander AED use from the first case in September, 2005 to September, 2008, which local fire departments provided.
FINDINGS: One hundred and seventy four case reports were collected. Patients’ age was 67.5±10.6 (mean±SD, 2 to 98) yo, and 113 were male while 61 were female. The number of PAD cases steadily increased from 3 in the first 4 months to 31 in the last 3 months (Fig.⇓). The most frequent location PAD applied was elderly nursing homes in 71 cases, followed by athletic venues or sports competition in 32 cases. Fifty seven cases were counter shocked, while 83 were prompted to be no-indicated. ROSC prior to hospital arrival was achieved in 45 patients. Inappropriate operation of AED was reported in 18 cases: incorrect handling in 6; pad removal after prompt or counter shock in 5; bystander hesitation to counter shock in 5; bystander confusion with implanted pacemaker in 1; and AED malfunction by soaking in 1. Also AED was applied in 6 non cardiac arrest patients.
CONCLUSIONS: PAD cases in Hyogo prefecture was increasing, but inappropriate operation was not rare. More promotion and knowledge provision about AED are needed.
