Step-by-step explanation:
The beginning of the modern Emergency Medical Services (EMS) system is widely considered to be marked by a groundbreaking paper titled Accidental Death and Disability: The Neglected Disease of Modern Society, published in 1966. This report was instrumental in highlighting the deficiencies of pre-hospital care and the urgent need for improved emergency medical systems. From professionalization efforts by the National Medical Association to the implementation of municipal planning and medical reforms, the development of EMS has been shaped by various advances in medicine and public health policies influenced by social perspectives on health and medicalization.
