Promoting the use of EHR Patient Portals is becoming more relevant for our society. With the increased usage of digital services to the consumers, the healthcare systems are one of the areas that demand more growth in their usage. With an increasingly older population and less healthcare resources available, the use of eHealth tools could play a critical role in the future sustainability of healthcare systems. We did a national survey, in Portugal, based on randomly generated mobile phone numbers and 8.6% of the responders mentioned that they are users of EHR Patient Portals. We also collected the usage patterns and socio-demographic information about healthcare consumers that use EHR Patient Portals. Compared with the Portuguese population they are younger, more educated and have a higher proportion of private health insurances.
