Background and purposeLiver cirrhosis is common, and timely diagnosis of decompensated cirrhosis may impact acute care and resuscitation. Point-of-care ultrasound is a core competency of US emergency medicine training and is increasingly available in many acute care settings, including those where usual diagnostic modalities of cirrhosis may not be available. Only a few works of literature exist that evaluate the ultrasound diagnosis of cirrhosis and decompensated cirrhosis by emergency physicians (EPs). We aim to evaluate whether EPs can diagnose cirrhosis by ultrasound after a brief educational intervention and determine the accuracy of EP-interpreted ultrasound compared to the radiology-interpreted ultrasound as a gold standard.MethodsThis single-center prospective single-arm educational intervention evaluated the accuracy of EPs diagnosing cirrhosis and decompensated cirrhosis on ultrasound before and after a short educational intervention. Responses were paired across the three assessments, and paired sample t-tests were performed. Sensitivity, specificity, and likelihood ratios were calculated using attending radiology-interpreted ultrasounds as the gold standard.ResultsEPs scored a mean of 16% higher on a delayed knowledge assessment one month after the educational intervention than on the pre-intervention assessment. EP-interpreted ultrasound revealed a sensitivity of 0.90, specificity of 0.71, positive likelihood ratio of 3.08, and negative likelihood ratio of 0.14 compared to radiology-interpreted ultrasound. The sensitivity of our cohort was 0.98 for decompensated cirrhosis.ConclusionsAfter a brief educational intervention, EPs can significantly increase their sensitivity and specificity in diagnosing cirrhosis using ultrasound. EPs were particularly sensitive in their diagnosis of decompensated cirrhosis.
