Liam Shaddock,1 Tony Smith2 1Medical Radiation Science, School of Health Sciences, The University of Newcastle, Newcastle, New South Wales, Australia; 2The University of Newcastle Department of Rural Health & School of Health Sciences, The University of Newcastle, Newcastle, New South Wales, AustraliaCorrespondence: Tony Smith, The University of Newcastle Department of Rural Health, C/- 69A High Street, Taree, Newcastle, NSW, Australia, Tel [phone], Email [e-mail]: Point of care ultrasound (POCUS) has become more common for rapid evaluation. Applications are limited by lack of training of users, difficulty maintaining ultrasound competencies, access to equipment for optimal imaging, and limitations in quality control. Such barriers exist in low-resource, underserved health care settings.Objective: The aim was to explore the use of POCUS in under-resourced health care settings, such as rural and remote locations in Australia and other countries. Key variables include health outcomes, quality of care, service availability, examinations types performed, equipment used, who performs the examinations, and the ultrasound training received.Methods: Literature was identified via CINAHL, Cochrane, Embase, Medline, PubMed, SCOPUS, and Web of Science, plus grey literature. Recommended guidelines were followed, and only research-based articles were included, with searches limited to English language and 2010–present.Results: After screening, 23 articles were reviewed. No studies had low risk of bias and, overall, the quality was poor and only two studies used random sampling. The majority were from developing countries, with only one performed in Australia. Echocardiographic screening in schools was common. Others included emergency department (ED) patients, abdominal aorta screening, obstetric scans, and intensive care unit (ICU) management. Operators included ED doctors, medical students, nurses, community healthcare workers and general practitioners, who received limited training in protocol-driven scanning, often monitored by experts. In comparison to clinical assessment, standard ultrasound or other imaging, accuracy was of the order of 70– 95%, depending on the condition, with high efficacy in improving patient care.Conclusion: Lack of studies of POCUS in Australia and other developed countries suggests a need for further research. Current evidence supports use of limited ultrasound using portable machines in locations with limited access to diagnostic ultrasound performed by sonographers, which has the potential to improve health outcomes in under-resourced communities in Australia and elsewhere.Keywords: point-of-care, POCUS, sonography, mobile, handheld, rural health
