They found that the rate of pathology picked up rose from 28% based on clinical examination to 72% after the POCUS examination. Point-of-care ultrasound led to changes in patient management, predominantly in fluid administration. Interestingly, on retrospective review, there was poor agreement between the junior doctor and POCUS expert reviewer on the interpretation of haemodynamic status, which had guided these management changes.
