Technology Characteristics Predicting End User Acceptance of Smart Intravenous Infusion Pumps

Abstract

Technology acceptance is an important predictor of end user technology usage. Perceptions of technology characteristics relating to usability and technical performance are particularly important to understanding user acceptance. This paper reports on the implementation of Smart intravenous infusion pumps at a tertiary care hospital. Nurse user perceptions of the technology usability (five dimensions), technical performance, and acceptance were measured one month after implementation. Overall, 42% of nurses responded positively towards accepting the pump. For 21 of 23 usability characteristics and performance questions, nurses were more likely to report neutral perceptions than positive or negative perceptions. The highest positive perceptions were for ease of learning to operate the pump and reliability of the pump. Six characteristics predicted end-user acceptance. Perceptions that the IV pump enhanced job effectiveness, made the job easier, increased safety of care, and functioned as expected predicted higher acceptance, while perceptions that alarm messages were frustrating and the pump interface was rigid predicted lower acceptance. Therefore, a new finding provided in this study is that highlighting improved patient safety when hospitals implement Smart intravenous infusion pumps may improve user acceptance of the pump.
