The Digitization of the ICU: An Evaluation of Usability and Hospital-Wide Acceptability.

This paper explores the impact of an electronic medication management system (EMMS) on users in an intensive care unit using the Unified Theory and Use of Technology constructs. It also explores the impact of having a consistent EMMS hospital wide, as it is the first Australian hospital to implement the same EMMS hospital wide. The research model was evaluated using survey data from 100 nurses, doctors and pharmacists both within the ICU and externally, to assess the usability and acceptability of the system. Results showed that performance expectancy, effort expectancy, social influence and facilitating condition all correlate with overall user satisfaction. Overall, teams external to the ICU are in strong favor of its implementation whist user acceptance from within the ICU itself is poor.
