EM Guideline Updates: Practical Take-Home Changes with Dr. Michael McCrea

Emergency medicine clinical practice is shifting due to recent guideline updates from major health organizations, including the AHA and ACEP. Key changes include simplified tachycardia algorithms for ACLS and PALS, which now emphasize standardized cardioversion dosing. Pulmonary embolism management now utilizes a five-category risk stratification system (A-E), empowering clinicians to safely discharge low-risk patients on direct oral anticoagulants. Stroke protocols have evolved to include pediatric stroke recommendations, extended-window thrombolysis for wake-up strokes using perfusion imaging, and a move against thrombolysis for sensory-only strokes. Furthermore, a new ACEP clinical policy enables the exclusion of non-traumatic aortic dissection by combining the Aortic Dissection Detection Risk Score (ADDRS) with a negative D-dimer. Dr. Michael McCrea, a speaker of the council and academic educator, details these evidence-based shifts to help community physicians optimize patient care and resource utilization.
