New healthcare technologies, such as bar-coded medication administration (BCMA), are implemented into rich, multiple-level work system, and jointly shape work processes. We provide theoretical and methodological rationale for studying these processes as a way to understand the impact of technologies in healthcare. Results are reported from a study conducted before and after implementation of BCMA in a pediatric hospital, in which the outcome of interest was satisfaction with the medication administration process. As predicted, two beliefs about the medication process, perceived ease of use and perceived usefulness, predicted satisfaction with the process before and after BCMA.
