- W2892091043 abstract "Aim: There is a scarcity of population based studies on out-of-hospital cardiac arrest (OHCA) in the Middle East and the wider Asian region. This study describes the Epidemiology and outcomes of OHCA in Qatar, a Middle Eastern country. Methods: Data was extracted retrospectively from a national registry on all adult cardiac origin OHCA patients attended by Emergency Medical Services (EMS) in Qatar, from June 2012 - May 2013. Results: The annual crude incidence rate of cardiac origin OHCA attended by EMS was 23.5 per 100,000. The age-sex standardized incidence rate was 87.83 per 100,000 population. The annual sex-standardized incidence rate for males and females was 91.5 and 84.25 per 100,000 population respectively. Of 447 adult, cardiac origin OHCA patients included in the final analysis, most were male (n=360, 80.5%) with median age of 51 years (IQR = 39-66). Frequently observed nationalities of OHCA cases were Qatari (n=89, 19.9%), Indian (n=74, 16.6%) and Nepalese (n=52, 11.6%). Common initial cardiac arrest rhythms were asystole (n=301, 67.3%), ventricular fibrillation (n=82, 18.3%) and pulseless electrical activity (n=49, 11%). OHCA was unwitnessed (n=220, 49%) in nearly half of the cases while bystanders witnessed it in 170 (38%) patients. Bystander CPR was carried out in 92 (20.6%) of the cases. Of 187 (41.8%) patients who were given shocks, bystander defibrillation was delivered to 12 (2.7%) patients. Prehospital outcomes; 332 (74.3%) patients did not achieve return of spontaneous circulation (ROSC), 40 (8.9%) patients achieved unsustainable ROSC, 58 (13%) achieved ROSC till Emergency department (ED) handover and 5 patients achieved ROSC but rearrested again before reaching ED. Survival to hospital discharge occurred in 38 (8.5%) patients. Neurological outcomes were assessed utilizing Cerebral Performance Category [CPC] scores with a favorable CPC score of 1-2 at discharge in 27 (6%) patients, while 11 (2.5%) patients had a poor CPC score of 3-4. Of those with CPC score 1-2 at hospital discharge, 59% and 26% had CPC score 1-2, at 1 and 3 years follow-up respectively. Overall survival was 9.7%. Conclusion: Standardized rates are comparable to western countries, there are significant opportunities to improve outcomes, including better bystander CPR." @default.
