Sustainability, as a science, is the guideline of the present work. It aims to analyse, by means of a literature review, various areas of healthcare in which information technology (IT) has been-or could be-used, leading to several sources of sustainability, for example, cost savings, better teamwork, higher quality and efficiency of medical care. After a brief introduction analysing the strategic contexts in which innovation in general, and IT in particular, can be a source of general improvements in efficiency, cost savings and service quality, the research focuses on the healthcare system by discussing the different nature of private and public organizations in terms of adopting innovations and changes and discussing the issue of consumer health costs and consumer choices. The following part focuses on the qualitative benefits of IT in healthcare and discusses the importance of metrics for measuring performance, costs and efficiency in this area. The work then qualitatively introduces a new set of Key Performance Indicators (KPI), partly based on literature from different topics and existing and validated sets of metrics, analysing, under the point of view of sustainability, the implementation of IT in healthcare, namely in management, organization, technology, environment and social fields (HHC-MOTES framework). The model, inspired by and to sustainability, can be used as a decision support at the strategic management level as well as for the analysis and investigation of the effects of IT systems in the healthcare sector from various perspectives.
