    AbstractThe objective of this study is to determine factors associated with successful resuscitation of out-of-hospital cardiac arrest (OHCA) patients by Narenthorn Emergency Medical Service Center (EMS), Thailand. A retrospective observational study was conducted with 73 OHCA patients who were resuscitated from December 2004 to January 2007. Inferential statistics, univariate (χ(2)) and multivariate analyses (logistic regression) were applied for data analysis. A total of 73 OHCA patients were included. The mean age was 58.3 years; 86.3% were ≥40 years, 72.6% were male. The causes of arrest were cardiac problem 53.4%. In all, 46.6% were witnessed arrest; 53.4% had response time (RT) ≥10 minutes, and 27.4% had bystander cardiopulmonary resuscitation (CPR). Overall, 79.5% were found in the residence. Initial electrocardiogram showed that 74% were nonshockable rhythm. A total of 34.2% were resuscitated by an EMS team with <4 members, and 53.4% had return of spontaneous circulation, survival to admission was 61.5% and survival to discharge was 7.7%. Witnessed arrest (odds ratio [OR] = 7.403; 95% confidence interval [CI] = 2.169-24.683) and bystander CPR (OR = 5.619; 95% CI = 1.014-36.170) had correlation with successful resuscitation of OHCA patients. RT showed a trend toward statistical significance (OR = 1.051; 95% CI = 0.765-16.083). This study found that witnessed arrest and bystander CPR were major factors associated with successful resuscitation of OHCA patients. Our findings will be useful for the development of community programs to decrease the mortality from OHCA.
