Multi-institutional Implementation of the National Clinical Assessment Tool in Emergency Medicine: Data From the First Year of Use.

Abstract

Uniformly training physicians to provide safe, high-quality care requires reliable assessment tools to ensure learner competency. The consensus-derived National Clinical Assessment Tool in Emergency Medicine (NCAT-EM) has been adopted by clerkships across the country. Analysis of large-scale deidentified data from a consortium of users is reported. Thirteen sites entered data into a Web-based platform resulting in over 6,400 discrete NCAT-EM assessments from 748 students and 704 assessors. Reliability, internal consistency analysis, and factorial analysis of variance for hypothesis generation were performed. All categories on the NCAT-EM rating scales and professionalism subdomains were used. Clinical rating scale and global assessment scores were positively skewed, similar to other assessments commonly used in emergency medicine (EM). Professionalism lapses were noted in <1% of assessments. Cronbach's alpha was >0.8 for each site; however, interinstitutional variability was significant. M4 students scored higher than M3 students, and EM-bound students scored higher than non-EM-bound students. There were site-specific differences based on number of prior EM rotations, but no overall association. There were differences in scores based on assessor faculty rank and resident training year, but not by years in practice. There were site-specific differences based on student sex, but overall no difference. To our knowledge, this is the first large-scale multi-institutional implementation of a single clinical assessment tool. This study demonstrates the feasibility of a unified approach to clinical assessment across multiple diverse sites. Challenges remain in determining appropriate score distributions and improving consistency in scoring between sites.
