Point-of-care-ultrasound for the assessment of post-renal transplant recipients.

ABSTRACT

INTRODUCTION: Postoperative imaging for deceased donor renal transplants is often delayed, as these surgeries occur after-hours. These delays can be critical in identifying immediate complications. To our knowledge, there are no formal training programs for point-of-care ultrasound (POCUS) in this setting; therefore, we aimed to develop and evaluate a feasible and practical POCUS curriculum for the assessment of a renal transplant graft. METHODS: Urology and nephrology transplant physicians completed a three-hour online course, followed by a five-hour hands-on seminar for sonographic scanning. Simulated patients with transplanted kidneys were used. Course material was developed with licensed ultrasound technologists based on Sonography Canada national competency profiles. Pre- and post-course surveys focused on user confidence, while pre- and post-course multiple-choice questionnaires assessed theoretical knowledge. RESULTS: Twelve participants were included, six of whom were urologists. Theoretical knowledge in POCUS improved significantly (p<0.001). Confidence in manipulation of ultrasound controls, Doppler imaging, and POCUS of the transplant kidney also improved (all p<0.001, d>2.0). Participants indicated an increased likelihood of POCUS use in clinical practice and that training should be integrated into a transplant fellowship. CONCLUSIONS: We introduced a novel and guideline-based POCUS curriculum that leveraged local ultrasound educators and found improved theoretical knowledge and skill confidence in our cohort of transplant physicians. This course will serve as the first step toward a validated competency-based training system for POCUS use in the immediate post-renal transplant setting, and likely will be incorporated into the training of the modern transplant physician.
