Now days Information technology has become a part of healthcare delivery this makes life much easier for patients and healthcare professionals. The increase in demand for communication among the different health information systems and health professionals has made interoperability complex and whereas interoperability is mainly focused at semantic and technical levels of communication. Yet, the social interoperability, an important part of communication between computerized systems and health professionals, is overlooked. In this study we explore the differences between interoperability and social interoperability. Furthermore investigate the social interoperability in practice and the problems that affect the healthcare. We start with the literature survey to learn the definitions of interoperability and social interoperability. Later, case study approach is carried out to investigate the social interoperability in Interoperability. Interviews were also conducted as part of the observations in cases. The similarities and differences in definitions of interoperability and social interoperability are sorted out from the literature study.
