In our #SmartHealthSystems study, we analyzed 17 countries on the state of digitization in health care. Estonia ranks first in our specifically developed Digital Health Index . As our country report shows, e-prescription and electronic patient files have been legally required in Estonia for a decade. Citizens can view their personal health data, find out about illnesses or book medical appointments online via the national health information portal. Since 2012, video consultations and telediagnostics are also permitted and integrated into outpatient care. In a Skype interview, Dr. Madis Tiik, family doctor and digital health expert, explains how Estonia has successfully accomplished digitization. The former CEO of the Estonian eHealth Foundation emphasizes the importance of clear competencies and a dedicated organization for the implementation of digital health processes. The trust of citizens thanks to transparency and a secure national infrastructure are further success factors, he points out.
