The Acute Care Common Stem (ACCS) is a globally recognised framework that offers a suite of standardised clinical scenarios, assessment tools, and teaching resources designed to train and evaluate healthcare professionals working in emergency, intensive‑care, and other acute‑care environments. By presenting realistic, high‑stakes cases that emphasize rapid decision‑making, effective teamwork, and mastery of essential procedural skills, ACCS helps learners develop the core competencies needed to manage critically ill patients safely and efficiently. The curriculum integrates simulation‑based learning, objective structured clinical examinations, and competency‑based milestones, ensuring that trainees receive consistent, evidence‑based instruction regardless of their institution or geographic location. Ultimately, ACCS aims to raise the overall quality of acute‑care delivery, improve patient outcomes, and foster a culture of continuous improvement among clinicians who regularly confront life‑threatening situations.
