Nowadays implementing an effective First Aid system at the workplace is a major challenge. However, there is little available data on specific regulations and training in these locations. 1 A previous survey has shown heterogeneity of practice in emergency care across the world, but without detailed answers to questions about First Aid regulations and training. 2 We aimed to conduct an online survey about world-wide First Aid regulation and cardiac arrest training, using International Red Cross and Red Crescent Societies and International Company Networks, and to describe inequalities correlating with country income.In December 2015 and January 2016, 109 questionnaires were analyzed from 64 countries, divided into three groups, according to Gross Domestic Product per capita, and purchasing power parity (current international US dollar, $27,000 and more for group A, 9000-26,999 for group B, and 0-8999 for group C). 3 ଝ All authors have participated to the conception and design of the study, or acquisition of data, or analysis and interpretation of data, drafting the article or revising it critically for important intellectual content, and final approval of the version submitted.
