|Abstract:||Checklists and global rating scales (GRSs) are used for assessment of anesthesia procedural skills. The purpose of this study was to evaluate the reliability and validity of a recently proposed assessment tool comprising a checklist and GRS specific for ultrasound-guided regional anesthesia. In this prospective, fully crossed study, we videotaped 30 single-target nerve block procedures performed by anesthesia trainees. Following pilot assessment and observer training, videos were assessed in random order by 6 blinded, expert observers. Interrater reliability was evaluated with intraclass correlation coefficients (ICCs) based on a 2-way random-effects model that took into account both agreement and correlation between observer results. Construct validity and feasibility were also evaluated. The ICC between assessors' total scores was 0.44 (95% confidence interval, 0.27-0.62). All 6 observers scored "experienced trainees" higher than "inexperienced trainees" (median total score 76.7 vs 54.2, P = 0.01), supporting the test's construct validity. The median time to assess the videos was 4 minutes 29 seconds. This is the first study to evaluate the reliability and validity of a combined checklist and GRS for ultrasound-guided regional anesthesia using multiple observers and taking into account both absolute agreement and correlation in determining the ICC of 0.44 for interrater reliability. There was evidence to support construct validity.|
