The American College of Medical Toxicology (ACMT) is an association of physicians with recognized expertise in the diagnosis, management, and prevention of human poisoning and other adverse health effects due to medications, occupational and environmental toxins, and biological agents. ACMT is proud to join the Choosing Wisely® campaign, as it directly aligns with its mission of advancing quality care of poisoned patients and public health. Concern for adverse health effects resulting from exposure to environmental toxins and medications used to treat disease affects all members of the population, and information available to the public and physicians regarding the diagnosis and management of poisoning can be confusing and conflicted. As the only organization representing Board Certified Medical Toxicologists, ACMT values the importance of research and evidence based practice in combating human poisoning. The Choosing Wisely campaign connects with these values and promotes awareness for patients and physicians of practices that are not cost-effective, necessary, or are potentially harmful. Joining this campaign supports ACMT’s goals of advancing the optimal care of poisoned patients and of being the pre-eminent education resource for all issues related to human poisoning.
