National Register of Assisted Reproduction (NRAR)

PURPOSE OF DETECTION OF REQUESTED DATA

The purpose of the register is registration of all women in whom ovarial stimulation was started or monitoring with the purpose of therapy of sterility (their own sterility or sterility of another woman in case of oocyte donation) was started by method of extracorporal fertilisation (IVF) or by related technique. Monitoring of IVF cycles secures necessary information on the method, progress, results and possible complications for the needs of professional health care workers, Ministry of Health of the CR, health insurance companies and also for international presentation of data. Information thus obtained allows evaluation f therapeutic procedures and are used for management and qualitative improvement of care for infertile couples and for realisation of state policy in the field of assisted reproduction and therapy of sterility. National register of assisted reproduction ()NRAR is a nationwide population register.

RANGE OF DATA PROVIDED BY HEALTH ESTABLISHMENTS TO NRAR

Since 2007, NRAR is operated as a web application with central database. Assisted reproduction centres insert data into the register by means of internet connection via secure https protocol. Access to the register and assignment of user roles is authorised by the administrator of the register.
