Epidemiology and outcomes of out-of-hospital cardiac arrest in Qatar: A nationwide observational study.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) studies from the Middle East and Asian region are limited. This study describes the epidemiology, emergency health services, and outcomes of OHCA in Qatar. METHODS: This was a prospective nationwide population-based observational study on OHCA patients in Qatar according to Utstein style guidelines, from June 2012 to May 2013. Data was collected from various sources; the national emergency medical service, 4 emergency departments, and 8 public hospitals. RESULTS: The annual crude incidence of presumed cardiac OHCA attended by EMS was 23.5 per 100,000. The age-sex standardized incidence was 87.8 per 100,000 population. Of the 447 OHCA patients included in the final analysis, most were male (n=360, 80.5%) with median age of 51years (IQR=39-66). Frequently observed nationalities were Qatari (n=89, 19.9%), Indian (n=74, 16.6%) and Nepalese (n=52, 11.6%). Bystander cardiopulmonary resuscitation (CPR) was carried out in 92 (20.6%) OHCA patients. Survival rate was 8.1% (n=36) and multivariable logistic regression indicated that initial shockable rhythm (OR 13.4, 95% CI 5.4-33.3, p=0.001) was associated with higher odds of survival while male gender (OR 0.27, 95% CI 0.1-0.8, p=0.01) and advanced cardiac life support (ACLS) (OR 0.15, 95% CI 0.04-0.5, p=0.02) were associated with lower odds of survival. CONCLUSIONS: Standardized incidence and survival rates were comparable to Western countries. Although expatriates comprise more than 80% of the population, Qataris contributed 20% of the total cardiac arrests observed. There are significant opportunities to improve outcomes, including community-based CPR and defibrillation training.

Craniocerebral gunshot injuries in preschoolers.

INTRODUCTION: Gunshot wounds (GSW) to the head are the most lethal form of trauma; unfortunately, the frequency of children being involved in such form of trauma is increasing at an alarming rate worldwide. We present our experience with four children from 2 to 3 years of age with craniocerebral GSW admitted to the neurosurgery service at a tertiary care hospital. METHODS: For this study, four children, 2 to 3 years old, injured solely from bullet injuries to the head were selected. Their history, arrival Glasgow Coma Scale (GCS), clinical presentation at the time of arrival in ER, radiological findings, management, and follow-up reviewed. RESULTS: Out of four children, only one did not survive. The bullet entrance wound was in the parietal region in robbery-related incidences, and, in three cases, the injury was bihemispheric. The time taken to reach the emergency department was less than 2 h for all patients except one. Of four patients, three presented with GCS between 3 and 5 while 1 presented with GCS well above ten. CONCLUSION: Our results show that even in children presenting with low GCS<5, an early act of aggressive surgical intervention can prove to be a life-saving measure.
