The study provides the result of a survey on Benchmarking deployment of eHealth services in acute hospitals in 30 European countries. Chief Information Officers were asked about the availability of eHealth infrastructure and applications in their hospitals whereas Medical Directors were asked about priority areas for investment, impacts and perceived barriers to the further deployment of eHealth. Applying state of the art multivariate statistical analysis to the data of survey of eHealth deployment in Acute European Hospitals funded by DG INFSO, JRC-IPTS researchers have constructed a composite indicator of take up and usage of eHealth in European hospitals, as well as a typology of impacts.
