George Dafoulas, internal medicine resident at the University of Athens, talks about how they used data from one of the largest e-prescription databases to develop epidemiology outcomes, and correlations with other diseases, concerning three specific non-biased chronic diseases. With the use of a university grant they analysed the Greek e-prescription data, which includes over 98% of local residents, developing one of the first large epidemiology studies in Europe. He and his team plan to continue developing their algorithm and methodology, well into the future. Interviewed by Vicki Kolovou for Tech Talks Central.
