Annals of Internal Medicine is an academic medical journal published by the American College of Physicians (ACP). It is one of the most widely cited and influential specialty medical journals in the world. Annals publishes content relevant to the field of internal medicine and related sub-specialties. Annals' mission is to promote excellence in medicine, enable physicians and other health care professionals to be well informed members of the medical community and society, advance standards in the conduct and reporting of medical research, and contribute to improving the health of people worldwide. To achieve this mission, the journal publishes a wide variety of original research, review articles, practice guidelines, and commentary relevant to clinical practice, health care delivery, public health, health care policy, medical education, ethics, and research methodology. In addition, the journal publishes personal narratives that convey the feeling and the art of medicine. Selected articles in the journal are open access; these include patient oriented content and Clinical Guidelines (and related reviews).[3]

In 2016 a commentary published in Nature claimed that Annals of Internal Medicine supports and defends the unethical, un-scientific practice of undisclosed research . The claims made by the author/activist were unsubstantiated and were addressed by the Annals editors in letters published online first in Annals of Internal Medicine.[6]
