Figure 1. Real-time renal biopsy simulation improves trainees’ confidence. From: Impact of ultrasound-guided kidney biopsy simulation on trainee confidence and biopsy outcomes.

(a) Comparing the pre-simulation (pre-test) to post-simulation (post-test) responses, trainees (n=16) gained 46.9 points in their confidence level (0-100 scale), increasing from 23.4±7.7(SEM) to 70.3±4.0 (p=0.001). (b) Fellows’ confidence was improved with the simulation training regardless of prior experience performing renal biopsy procedure, indicated by a non-significant interaction between experience and time (pre vs post-simulation; F[1,14]=4.18; p=0.060; eta squared 0.23; grey shading corresponds to pre-simulation and black shading to post-simulation responses).

Figure 2. Real-time renal biopsy simulation improves trainees’ competence and reduces biopsy-associated blood loss. From: Impact of ultrasound-guided kidney biopsy simulation on trainee confidence and biopsy outcomes.

(a) Fellows who received the simulation training had higher success rate in retrieving biopsy core pieces per pass than those who did not receive the training [0.94 ± 0.05 vs 0.73 ± 0.04 pieces per pass; t=(−3.75); p=0.002]; based on 53 biopsies performed by fellows who did not (21 biopsies) vs did (32 biopsies) participate in the simulation training.
(b) Fellows who received the simulation training had lower post- vs pre-biopsy Hct decline (1.18 ± 0.49 vs 2.13 ± 0.50; t=2.13; p=0.049). There was no major bleeding complication in this group of patients.
