title: Data of "Epidemiology of Out-of-Hospital Cardiac Arrests,Knowledge of Cardiovascular disease and Risk Factors in a regional setting in India: The Warangal Area out-of -hospital Cardiac Arrest Registry (WACAR)

description: Out-of-Hospital Cardiac Arrest (OHCA) is a global public health problem.While several OHCA registries are developed based on the Utstein template, there is limited data on OHCA from India.The Warangal Area out-of-hospital Cardiac Arrest Registry (WACAR) was designed to gain a better understanding of OHCA in a regional setting in India. The WACAR is a prospective one-year observational study of OHCA in Warangal area in the State of Telangana, India.OHCA cases were obtained from a regional Government Hospital, Mahatma Gandhi Memorial Hospital, a secondary care District Headquarters Hospital. Study subjects included all those above 18 years brought to the hospital with a history of non-traumatic OHCA of presumed cardiac origin from January 1, 2018 - December 31, 2018. A total of 814 individuals were included in the study for data analysis. The data are collected on a standard collection form designed with Utstein variables with additional data on clinical characteristics (modified Utstein template). It includes information on demographics, patient characteristics, risk factors, history of heart disease, comorbidities, prior symptoms, resuscitation characteristics, event timing, utilization of Emergency Medical Services (EMS) and outcomes. Study data were obtained from a review of hospital records. Medical staff involved in the care of OHCA were given data collection forms that were filled out in the emergency room setting. Information not obtained during initial emergency room evaluation was obtained from bystanders (including victim’s relatives and attendants) through telephone interviews. Results: A total of 1106 subjects of OHCA attended MGM Hospital during January 2018 and December 2018. After excluding those due to trauma, hanging, and burns, the sample size of OHCA was sized down to 926 subjects and 814 subjects with Presumed Cardiac etiology were included in the study for analysis. The results are tabulated into demographics, patient characteristics and resuscitation characteristics. Majority of subjects were male, with a median age of 60 years. The majority occurred in residential locations and sustained OHCA within one hour of symptom onset. Individuals with knowledge of CVD risk factors were more likely to report symptoms before OHCA. Data on resuscitation characteristics were inadequate. Conclusions: WACAR gives insight into the epidemiology of OHCA in India.The results of WACAR highlight that OHCA of cardiac etiology is a significant public health problem in India.The study demonstrated barriers involving patient knowledge of CVD ,risk factors, data collection, and access to health care. The study results also convey that the knowledge level of CVD risk factors and personal CVD disease have a significant impact on OHCA outcomes. The information from the WACAR registry, the first registry on OHCA in this setting points to the need for a Indian National OHCA Registry and might help to guide future steps to improve care OHCA in India.
