Abstract 13655: Factors Influencing the Occurrence of Cardiopulmonary Arrest in the Great East Japan Earthquake Disaster
Background: We have previously reported that the Great East Japan Earthquake increased the occurrence of cardiopulmonary arrest (CPA). In this study, we assessed the factors influencing the occurrence of CPA of presumed cardiac origin in the Disaster.
Methods and Results: We enrolled all patients with CPA of presumed cardiac origin by using the ambulance transport records database of Miyagi Prefecture, the center of the Disaster area, from February 11 to June 30 of 2008-2011 (n=2,534) and compared the weekly occurrences in 2011 with those in the previous 3 years. In the whole patients, the weekly occurrence of CPA was significantly increased with the bimodal peaks noted in the first 2 weeks after the Earthquake (March 11, 2011) and in the week just after the largest aftershock (April 7, 2011) compared with the previous 3 years. Sub-group analyses for sex, age (<75 or ≥75 years) and residence (seacoast vs. inland area) showed that the occurrence of CPA was significantly increased soon after the Earthquake in all groups, whereas the second peak after the largest aftershock was noted only in female, elderly and inland patients (Figure). In addition, elderly and seacoast patients had a sustained increase in the occurrence of CPA over a period of 4 weeks after the Earthquake (Figure). A multivariate analysis was performed to identify the factor that contributed to the increase in CPA after the Earthquake, demonstrating that significant influence of higher age ≥75 years on the increase in CPA [OR (95% CI); 1.82 (1.04-3.20), P=0.04] was noted in 4-6 weeks after the Earthquake, while female gender [1.57 (0.97-2.54), P=0.07] and seacoast residence [1.54 (0.91-2.59), P=0.11] tended to correlate with the increase in CPA in the period of 0-4 weeks after the Earthquake.
Conclusions: These results indicate that the increase in the occurrence of CPA after the Earthquake was influenced by sex, age, and residence, providing a clue to reduce CPA in future disasters.
