Point-of-care ultrasound, anchoring bias, and acute pulmonary embolism: A cautionary tale and report.

Emergency physicians often rely on heuristics to facilitate clinical decisions due to the large volume of patients they see daily. Consequently, they are vulnerable to error and bias. We report the case of a 69-year-old male that presented to the emergency department (ED) with shortness of breath, productive cough, and dyspnea on exertion. One day prior to ED admission, he was diagnosed with bronchitis; however, point-of-care ultrasound (POCUS) in the ED identified acute pulmonary embolism. This case illustrates the potential dangers of anchoring bias and shows the benefits of using point-of-care ultrasound of the lungs and heart to assist in the diagnosis of acute pulmonary embolism.
