This innovation action will give a powerful impulse to implementation of ISO IDMP (ID of Medicinal Products) standards in EU Member States drug databases, supporting safe cross-border ePrescription/eDispensation and effective pharmacovigilance. Once EU-interoperable data on medicines taken by patients become available, further benefits will accrue through better health data for improved clinical decision support, patient empowerment, public health and clinical research. New opportunities will arise for pharma industry, software developers, SMEs providing smart apps and others, thereby fostering their innovation capacity and competitiveness. The many challenges still to be faced on this road will be tackled by a powerful consortium assembling all relevant actors, with critical mass for impact throughout the EU. After 10 years of development, the IDMP suite of standards is ready for implementation. Though some isolated implementation work has started, the time is now ripe for a more concerted effort towards large-scale implementation, contributing to this global interoperability endeavour and delivering benefits to EU citizens. Project ambition centres on conversion of key regulatory and clinical processes to use IDMP. These information value chains must be converted over their full length from data input to data repositories to data usage. Project work spans all three areas, focussing on the most challenging, the implementation of EU and national SPOR (substances, products, organisations, referentials) data bases, including establishing an EU Substance Reference System (EU-SRS). Such information is fundamental to cross-border ePrescription where safe dispensation may require reliable identification of substances in available products. 19 countries are represented, including 26 national Drug and eHealth Agencies. Stakeholders are involved through their associations. Duration is 4 years, budget € 21 m, with requested funding € 19 m.
