title: Incidence and outcomes of out-of-hospital cardiac arrest in the eastern part of Yamaguchi prefecture.
abstract: The aim of the present study was to evaluate the factors related to poor prognosis of out-of-hospital cardiac arrest patients in one local area of Japan. From May 1, 2002 to April 30, 2008, a total of 442 patients with cardiopulmonary arrest were transferred for resuscitation to the National Hospital Organization, Iwakuni Clinical Center. Of 325 patients with cardiopulmonary arrest of cardiac etiology, 126 patients were witnessed by a bystander. However, only 37 received bystander cardiopulmonary resuscitation, 13 had shockable cardiac rhythm, 3 survived 1 month, and 2 had a good neurological discharge. Multivariate analysis of overall cardiac arrest showed that 1-month survival and neurologically favorable discharge were associated with bystander cardiopulmonary resuscitation (P=0.049 and 0.013) and initial shockable cardiac rhythm (P=0.001 and 0.007). In this region, the survival rate for patients with cardiopulmonary arrest was lower than that reported in other areas, probably because fewer patients received bystander CPR or had shockable cardiac rhythm. This may result from CPR being less popularized in this region than in other areas, suggesting that raising the awareness of CPR would improve the survival rate.
