**Core Concept**
The Advanced Trauma Life Support (ATLS) program is a standardized course for teaching the principles of trauma care. It emphasizes a systematic approach to assessing and managing trauma patients, focusing on the 'ABCDE' approach: Airway, Breathing, Circulation, Disability, and Exposure.

**Why the Correct Answer is Right**
The ATLS program was developed by the American College of Surgeons (ACS) Committee on Trauma (COT) to provide a uniform approach to trauma care. The program teaches healthcare professionals to assess trauma patients using a systematic approach, prioritize life-threatening injuries, and manage trauma patients in a standardized and efficient manner. The 'ABCDE' approach is a key component of ATLS, guiding healthcare providers to assess and manage trauma patients in a logical and systematic way.
