Interoperability Capability to interoperate in a shared work practice using information infrastructures studies in ePrescribing

Abstract: The ability to interoperate between systems, people, and organizations is considered an important issue within eHealth in order to deliver patient centered care. The achieving and improving of interoperability is a complex undertaking involving the evolution of an information infrastructure, sharing of knowledge and resources, governance of the interoperation between organizations, people and work practices, and handling of economic and legal matters.This thesis contributes with practical knowledge on improving interoperability, based on active participation in and empirical studies of improving interoperability in ePrescribing. A case study describes and analyzes the evolution of ePrescribing in Sweden since the early pioneering years in 1980s, its growth and consolidation before the reregulation of the pharmacy market in 2009. Apractical theory on ePrescribing is presented. A unique field experimental study measuring improvement of interoperability in ePrescribing, before and after a major intervention to improve the quality of ePrescriptions between 2004 and 2009 is presented.Furthermore, a practical theory on interoperation and interoperability is presented. Interoperability is seen as the exercised capability of organizations through their agents to interoperate in a shared work practice in an effective, efficient, and satisfactory manner based on a common ground in a mediated, prescriptive, and non-personal communicative setting using an information infrastructure for mediating interoperation.
