Anaphylaxis in practice: A guide to the 2023 Practice Parameter Update.

This review will summarize new research developments and clinical practice recommendations for the diagnosis and management of anaphylaxis presented in the Joint Task Force on Practice Parameters' 2023 Anaphylaxis Practice Parameter Update. It is intended to serve as a high-level summary of the 2023 practice parameter, which makes clinically impactful recommendations based on new evidence that has emerged since the 2015 practice parameter. We invite clinicians to explore the full 2023 practice parameter to better understand the research methods and underlying evidence that have informed the recommendations summarized here. There are new and evolving diagnostic criteria for anaphylaxis, rules for defining elevated tryptase levels, and recognition of signs and symptoms particular to infants and toddlers. The administration of epinephrine should not be used as a surrogate to diagnose anaphylaxis. Risk factors for anaphylaxis should be assessed on a case-by-case basis. Patient counseling and shared decision making (SDM) are essential for supporting patients' treatment decisions and capacity to manage the risk of anaphylaxis at home and in other community settings. Activation of emergency medical services following home epinephrine administration may not be required in all cases, and patients should be engaged in SDM to determine when home management may be appropriate.
