Enthusiasts are plentiful as are detractors. Enthusiasts claim that POCUS augments clinical examination to expedite diagnosis, thus improving management. Detractors claim that POCUS is an inadequate substitute for comprehensive diagnostic ultrasound that leads to misdiagnosis. Both are true. This issue of AJUM is all about POCUS.</p><p>Wong <i>et al</i>.<span>¹</span> present data on the role of focussed cardiac and lung ultrasound performed by a junior doctor as part of the pre-operative assessment in patients undergoing non-cardiac surgery. 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. Point-of-care ultrasound will change management regardless of its accuracy, highlighting the importance of adequate training and quality assurance structures for novice users, particularly for identifying when image quality is too poor to allow meaningful interpretation.</p><p>Using ultrasound to augment clinical examination is an important part of POCUS, and Pettit <i>et al</i>.<span>²</span> present a study showing that, after brief training, medical students and junior doctors improved their diagnosis of elevated jugular venous pressure (JVP) using ultrasound and that ultrasound resulted in similar clinical estimations as experienced cardiologists using physical examination.

A more nuanced reply to the question as to why the examination is being done might be, ‘To assist your doctor make decisions about your management’. As to whether the report is useful, ‘If you answered the clinical question and provided measurements and information that will help guide management it was useful’. And to the third question, the ubiquitous pre-discharge examination, my typical reply is almost always, ‘Do it as an outpatient, or if it's critical to your management decisions, keep them in and we will do it next week’.
