INTRODUCTION: The establishment and operation of disease registry can be used to collect data on epidemiology cases. In addition, the registry can help to work out medical and health economical and political decisions for longer term. AIM: The aim of the authors was to collect and analyse data of @entity1 with @entity5 in Hungary and draw conclusions about the basic types and features of the relevant disease. METHOD: An online electronic data collection system has been established, based on the permission of the Regional and Institutional Committee of Science and Research Ethics obtained in April 8, 2013. Data collection has been initiated by hematology centres in Hungary. In addition to collection of the epidemiology data, blood and bone marrow analysis data have been collected. Also, based on cardiovascular medical factors, risk stratification has been carried out. Finally, the authors have investigated the method and practice for @entity1 treatment in Hungary. RESULTS: Data of 901 @entity1 from 15 Hungarian haematology centres have been recorded up to the date of June 30, 2015. After clarification of the data, 426 @entity11998 vera, 350 essential thrombocythaemia and 82 @entity4018 cases were used for analysis. CONCLUSIONS: An online registry has been established which helps to clarify and analyse the basic features of certain medical cases and their treatment in Hungary. Including additional medical centres could help to improve the accuracy of medical analysis. Orv. Hetil., 2016, 157(3), 98-103.
