Point-of-care ultrasound in primary care

Previously, ultrasound examinations have been performed by specialized personnel using advanced scanning devices. But with the current development in technology the devices are now smaller, more portable as well as cheaper, and thus more available also to clinicians in primary care.

SBU Enquiry Service

Consists of structured literature searches to highlight studies that can address questions received by the SBU Enquiry Service from Swedish healthcare or social service providers. We assess the risk of bias in systematic reviews and when needed also quality and transferability of results in health economic studies. Relevant references are compiled by an SBU staff member, in consultation with an external expert when needed.

Question

What scientific studies are there investigating the use of point-of-care ultrasound in primary care?

Identified literature

One systematic review with high risk of bias [1] and eight primary studies [2-9] were found relevant for the question. The primary studies were not assessed for risk of bias.
