Cardiopulmonary point-of-care ultrasonography (POCUS) is a rapid bedside tool that could improve diagnostic accuracy and timeliness for patients with dyspnea. Despite growing endorsement from professional societies, POCUS adoption among hospitalists remains inconsistent and is hindered by variable training, time constraints, and lack of structured implementation. In a quality-improvement study — with a 6-month, stepped-wedge, randomized design — at a U.S. tertiary academic hospital, researchers evaluated 208 patients (median age, 71) who were admitted with undifferentiated dyspnea to receive either standard care (formal echocardiography when clinically indicated) or cardiopulmonary POCUS evaluation. Twenty percent of POCUS exams were…
