A comprehensive needs assessment was conducted at ATA hospital to determine the root causes of a high number of errant radiology orders from requesting physicians. The Human Performance Technology Model, Gilbert's Behavior Engineering Model, and Rummler and Brache's Nine Performance Variables Model guided the needs assessment process. Three solutions were proposed. The development of the long-term solution, a software utility, has been initiated. The Behavior Engineering Model was used to identify possible solutions to post-training performance gaps identified during the evaluation.
