Experience and training as determinants of grading reliability when assessing the severity of contact lens complications
Efron, Nathan, Morgan, Philip B., Farmer, Craig, Furuborg, Jan, Struk, Robert, & Carney, Leo G. (2003) Experience and training as determinants of grading reliability when assessing the severity of contact lens complications. Ophthalmic and Physiological Optics, 23(2), pp. 119-124.
PURPOSE: A study was conducted to investigate the influence of experience and training on grading reliability when assessing the severity of contact lens complications. METHODS: Twenty-three optometry students who were unfamiliar with the use of grading scales each used the Efron Grading Tutor computer program to ascertain grading reliability at an 'initial' experimental session and a 'final' session 3 weeks later. Twelve subjects (the 'trained' group) were given a tutorial on grading techniques and were asked to complete two grading exercises between the initial and final sessions. The other 11 subjects (the 'untrained' group) received no such training between the two sessions. Differences in grading reliability between the initial and final grading sessions were evaluated. RESULTS: Grading reliability was superior (lower) for the combined subject cohort at the final session (mean +/- standard deviation 0.33 +/- 0.12) compared with the initial session (0.46 +/- 0.25) (p = 0.004). However, there was no difference in the improvement in grading reliability between the two groups. CONCLUSIONS: Grading reliability improves statistically with some experience, although perhaps not to a clinically meaningful extent. No added benefit can be derived from supplemental training.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
