With consistent cross-country information on these issues largely absent, the OECD has used lessons learned from case studies in Australia, Canada, the Netherlands, Spain, Sweden and the United States to identify the opportunities offered by ICTs and to analyse under what conditions these technologies are most likely to result in efficiency and quality-of-care improvements. The findings highlight a number of practices or approaches that could usefully be employed in efforts to improve and accelerate the adoption and use of these technologies.
