Abstract

The overall aim of this study is to evaluate the usability of U.S. military electronic health record (EHR) system AHLTA using a systematic work-centered evaluation framework UFuRT --- User, Functional, Representational, and Task Analysis. This paper with the focus of Functional Analysis (FA) of AHLTA explores operationalizable methods to study functions supported by user interfaces. A system hierarchy was created to map and uniquely identify all items on the interfaces. These items were then classified independently by 2 evaluators as Operations or Objects. Operations were further classified as either Domain or Overhead function. With acceptable inter-rater agreement, of the 1996 items in the interfaces, 61% were operations, around one fourth of which were Overhead functions. Overhead functions are hypothesized to be targets to be redesigned for improvements in usability.
