Background: Although some studies have questioned whether cardiopulmonary resuscitation (CPR) in older people could be futile, age is not considered an essential out-of-hospital cardiac arrest (OHCA) prognostic factor. However, in the daily clinical practice of mobile medical teams (MMTs), age seems to be an important factor affecting OHCA care. Aims: The purpose of this study was to compare OHCA care and outcomes between young patients (<65 years old) and older patients. Methods: We performed a case-control study based on data extracted from the French National Cardiac Arrest (CA) registry. All adult patients with CA recorded between July 2011 and May 2014 were included. Each older patient was matched on three criteria: sex, initial cardiac rhythm and no-flow duration. Results: We studied 4347 pairs. We found significantly less basic life support initiation, shorter advanced cardiac life support duration, less MMT automated chest compression, less MMT ventilation and less MMT epinephrine injection in the older patients. Significant differences were also observed for return of spontaneous circulation (odds ratio (OR)=0.84, 95% confidence interval (CI) 0.77–0.92, p<0.001), transport to hospital (OR=0.58, 95% CI 0.51–0.61, p<0.001), vital status at hospital admission (OR=0.55, 95% CI 0.50–0.60, p<0.001) and vital status 30 days after CA (OR=0.42, 95% CI 0.35–0.50, p<0.001). Conclusion: All OHCA guidelines, ethical statements and clinical procedures do not propose age as a discrimination criterion in OHCA care. However, in our case-control study, we notice a shorter duration and less intensive care among older patients. This finding may partly explain the lower survival rate compared with younger people.
