Abstract

OBJECTIVES: To study the construct validity and reliability of a novel endovascular global rating scale, Structured Assessment of endoVascular Expertise (SAVE). DESIGN: A Clinical, experimental study. MATERIALS: Twenty physicians with endovascular experiences ranging from complete novices to highly experienced operators performed a video-recorded simulated contra-lateral iliac-artery-stenting procedure. The virtual-patient case was a novel technically challenging procedure presenting the distal arteries below the knee. METHODS: Three experts assessed the performances blinded to operator identity. Validity was analysed by correlating experience with performance results. Reliability was analysed according to generalisability theory. RESULTS: The mean score on the 29 items of the SAVE scale correlated well with clinical experience (R = 0.84, P 5000 procedures) obtained maximum scores. The inter-rater reliability was high (G = 0.94 and G = 0.95). The procedure time (median 69 min, range 32-86) correlated moderately with clinical experience (R = -0.53, P
