Founded in 1905, the American Society of Anesthesiologists (ASA) is a professional association representing physicians specialising in anesthesiology. With over 53,000 members across the United States and worldwide, it serves as the leading body for the specialty, offering advocacy, education, and clinical resources.
The organisation publishes the peer-reviewed journal Anesthesiology and hosts the annual ANESTHESIOLOGY meeting, one of the field's principal professional gatherings. It also developed the Perioperative Surgical Home model, a programme aimed at improving surgical patient care through coordinated, team-based approaches.
ASA's work centres on advancing patient care and safety, supporting medical research, and providing professional development resources for its members. Its activities span the broader healthcare and medical sectors, with a primary focus on anesthesiology practice, policy, and scientific advancement.
