Abstract

PURPOSE: To develop an internationally standardized and validated tool to assess skill in performing tube shunt surgery. DESIGN: A panel of 6 glaucoma surgeons developed a tool for assessing tube shunt surgery using a modified Dreyfus scale for skill acquisition. The tool was reviewed by a panel of 10 international content experts, and their comments were incorporated into the final rubric. PARTICIPANTS: A different panel of 8 international glaucoma specialists independently graded videos of surgical procedures performed by 6 surgeons at various levels of ophthalmic training. MAIN OUTCOME MEASURES: Inter-rater reliability for each step in the rubric was calculated. RESULTS: The tube shunt rubric contained 13 steps specific to tube shunt surgery and 7 global indices. The Cronbach α statistic, a measure of internal reliability, ranged from 0.75 to 0.97, indicating strong internal reliability for all 13 steps. CONCLUSIONS: The tube shunt assessment tool has face validity, content validity, and interobserver reliability, and can be used to assess tube shunt surgery skills. Further studies are required to determine predictive and construct validity.
