Background: The Advanced Trauma Life Support (R) (ATLS (R)) course
provides a standard approach to trauma. Participants must pass the ATLS
(R) post-test. We deployed the test online to allow ongoing psychometric
item analysis and potential objective refinement.
Methods: A two-phase study was undertaken with the ACS COT permission.
In the first phase, ATLS (R) post-test #2 was computerized and deployed
using Qualtrics (c). Data were collected from fourteen courses conducted
between 2014 and 2015 (n = 306) at one ACS AEI site. In the second
phase, the same post-test was administered to 238 trainees in 10 courses
via secured computers at four ACS AEI sites in 2016.
Results: Phase 1 item analyses showed two items with very low
percentages correct, and one of these also showed a low discrimination
index. Phase 2 item analyses suggested four items as candidates for
review and possible revision. We also found differences by learner
background and by instructional site.
Conclusions: This study demonstrates computerized delivery of the ATLS
post-test is feasible, promotes psychometric analysis, and could improve
the quality of the test. Further collaboration between the ACS COT and
ACS AEI would be beneficial. (C) 2018 Elsevier Inc. All rights reserved.
