Abstract 234: Temporal Trends of Resuscitation Characteristics After Out of Hospital Cardiac Arrest: Data From a National Survey of Sudden Cardiac Arrest Survivors
Introduction: We have little data from survivors of sudden cardiac arrest (SCA). We sought to learn resuscitation characteristics of those who survived out of hospital cardiac arrest (OHCA) and determine if these changed over recent years.
Methods: An on-line survey regarding circumstances before and after cardiac arrest was emailed to 591 SCA survivors registered with the Sudden Cardiac Arrest Association (Washington, DC) between 10/2012 and 1/2013. Data were analyzed for temporal trends in resuscitation characteristics among survivors whose cardiac arrest was outside the hospital.
Results: Overall, 189 (32%) survivors responded; of these, arrest occurred outside the hospital in 169. Mean age of respondents with OHCA was 55+/-12 years (range 18-82); 55% were male, and 94% white. Heart disease was known to be present before the arrest in 37% and was diagnosed in 22% after arrest; no heart disease was found in 41%. Arrest occurred within the last two years in 22%, between two and five years ago in 38%, and greater than five years ago in 63% (range 1 month-17 years). Bystander CPR rates were high and trended higher in more recent years. There were no home uses of AED reported; AED use at public sites did not differ by time period. The frequency of therapeutic hypothermia was higher if arrest occurred within the last five years.
Conclusion: Among OHCA survivors, treatment with therapeutic hypothermia increased over time among survivors, but rates of bystander CPR and AED use did not. Opportunities for improved initial care of persons with OHCA persist, both prehospital and after hospital arrival.
