Ultrasound has been described as the stethoscope for the 21st century. It can rapidly answer a specific clinical question or support a procedure. Use of point-of-care ultrasound (PoCUS) by doctors has increased in the UK and internationally over the past decade. Training in PoCUS is now a core part of some undergraduate and postgraduate learning curricula. The World Organization of Family Doctors (WONCA Europe) has endorsed use of PoCUS in general practice. The rapid uptake of PoCUS in primary care in other countries suggests that the UK may soon follow suit. This article aims to provide an overview of PoCUS in primary care, including what PoCUS is, its current and potential use within primary care, limitations, legal considerations, and resources to develop an interest and skill in PoCUS as a GP in the UK.
