Update in Outpatient General Internal Medicine: Practice-Changing Evidence Published in 2021

It can be challenging to identify new evidence that may shift clinical practice within internal medicine. Synthesis of relevant articles and guideline updates can facilitate staying informed of these changes. The titles and abstracts from the 7 general internal medicine outpatient journals with highest impact factors and relevance were reviewed by 8 internal medicine physicians. Coronavirus disease 2019 research was excluded. The New England Journal of Medicine (NEJM), The Lancet, Journal of the American Medical Association (JAMA), The British Medical Journal (BMJ), Annals of Internal Medicine, JAMA Internal Medicine, and Public Library of Science Medicine were reviewed. Additionally, article synopsis collections and databases were reviewed: American College of Physicians Journal Club, NEJM Journal Watch, BMJ Evidence-Based Medicine, McMaster/DynaMed Evidence Alerts, and Cochrane Reviews. A modified Delphi method was used to gain consensus based on clinical relevance to outpatient internal medicine, potential impact on practice, and strength of evidence. Article qualities and importance were debated until consensus was reached. Clusters of articles pertinent to the same topic were considered together. In total, 8 practice-changing articles were included.
