The goal of this longitudinal study is to examine the evolution of the perceptions, namely anxiety, ease of use, usefulness, misfit (not customization), trust and usefulness, related to an Electronic Medical Record (EMR) for the clinical staff in a French Teaching hospital. Two surveys were conducted first in September 2013 and second in December 2015, based on a questionnaire consisting of items on the Likert scale. As results, the correlation of all the variables between the two surveys is very significant (except for usefulness, for which the relationship is significant). This is not surprising, given previous studied focused on habits and learning related to technology adoption. Nevertheless, the increase is not spectacular and it makes necessary to evaluate EMR satisfaction and perceptions in order to elaborate a measure standard enabling comparisons and benchmarking among hospitals.
