Gaps in point of care ultrasound provision and the cost of ultrasound equipment provision: results of a nationwide audit of acute medical units

Abstract

Introduction: Advances in ultrasound technology have allowed an investigation previously restricted to the radiology department to be used more liberally in clinical decision making. Point-of-Care-Ultrasound (PoCUS) has superior diagnostic performance to traditional clinical examination across a range of pathologies in the hands of a suitably experienced practitioner. The utilisation of PoCUS has the potential to greatly influence the delivery of acute care, but little is known about the current level of resource provision within the acute medical setting. Methods: To establish the availability of ultrasound equipment and appropriately trained clinicians within Acute Medical Units (AMUs) in the United Kingdom (UK) we asked specific questions with an annual day of care survey, undertaken by the Society for Acute Medicine. We compared data across two years to assess interval changes. Results: 58.1% (75/129) of AMUs had access to dedicated ultrasound equipment in SAMBA’19. This represents a small increase from SAMBA’18. Ultrasound expertise is concentrated across a small number of AMUs. Growth in the number of ultrasound trained clinicians is greatest units with established expertise. Conclusion: The equipment to provide PoCUS is not present on all AMUs and appropriately trained clinicians are not distributed evenly across units. This is likely to affect individual AMUs ability to deliver bedside ultrasound to appropriate patients who may benefit. Bridging the gap to ensure all AMUs have the option to use PoCUS will require planning and investment.
