Current use, training, and barriers in point-of-care ultrasound in nephrology: A national survey of VA medical centers.

BACKGROUND

Point-of-care ultrasound (POCUS) can improve diagnostic accuracy, reduce procedural complications and enhance physician-patient interactions in nephrology. Currently, there is limited knowledge about how practicing nephrologists are using POCUS.

OBJECTIVE

This study aimed to characterize current POCUS use, training needs, and barriers to use among nephrology groups.

MATERIALS AND METHODS

A prospective observational study of all Veterans Affairs (VA) medical centers was conducted between August 2019 and March 2020 using a web-based survey sent to all chiefs of staff and nephrology specialty chiefs.

RESULTS

Chiefs of staff (n = 130) and nephrology chiefs (n = 79) completed surveys on facility- and service-level POCUS use (response rates of 100% and 77%, respectively). Current diagnostic or procedural POCUS use was reported by 41% of nephrology groups, and the most common POCUS applications were central line insertion (28%) and assessment of urinary retention (23%), hydronephrosis (18%), volume status (15%), and bladder (14%). Lack of training was the most common barrier (72%), and most nephrology groups (65%) desired POCUS training. Limited access to ultrasound equipment and POCUS training were barriers reported by 54% and 18% of groups, respectively.

CONCLUSION

A minority of nephrology groups currently use common POCUS applications including evaluation of urinary retention, hydronephrosis, and volume status. The most common barriers to POCUS use in nephrology were lack of trained providers and ultrasound equipment. Investment in POCUS training and infrastructure is needed to expand and standardize POCUS use in nephrology.
